Optimum comfort and efficiency with electrical heating Electrical heating is reliable, com-fortable, easy to use and economi-cal. It is suitable for all rooms in a house and post-construction in-stallation is easy. Electrical heating provides a comfortable and even warmth, making life a pleasure. No wonder that electrical heating is the most popular heating system in new single-family homes in Fin-land. The energy used for electri-cal heating transforms efficiently into heat. Energy consumption can be optimised and costs saved with accurate heating control. A well-designed heating control reacts to solar radiation and heat produced by a room’s occupants, keeping the temperature even in all conditions. The room temperature can be lowered for short periods of time, to save energy.

An economical and functional solutionThe initial investment in electrical heating is small; the saving com-pared to other systems can be more than 10,000 euros. Operating costs are comparable or even lower than those of oil heating. Geo-thermal pump heating is cheaper to use than electrical heating, but the high initial cost makes the in-

vestment pay-back time very long for an average-sized single-family home.

The maintenance required for electrical heating is almost negli-gible. Heating control is easy and there is no risk of fuel running out. When faults are detected they are easy to fix, and the fault will not damage the structures of the house.

Three ways to use electricity for heatingEnsto offers the possibility to design comfortable and efficient electrical heating. You can choose between floor and ceiling heating and tradi-tional heating using electrical panel heaters. Ensto also has solutions for defrosting main pipes, gutters and outside areas. A heating system suitable for each space can be de-signed by combining different heat-ing methods using Finnish quality products. Ensto’s product range also offers ease of installation and maintenance-free heating.

Why electrical heating?This pamphlet describes the vari-ous possibilities offered by electri-cal heating and frost protection, alongside examples. Instructions for design and installation are given with each selection. To aid

design, we have built three levels of electric heating: Superior, High and Medium. The main difference between the different levels is their heating comfort. Thermostats de-signed for each product are used to control heating. In this way, heating control is centralised and easy to use. Using the correct type of heat-ing control, optimises energy con-sumption and saves money. Techni-cal details and tables on Ensto’s products can be found at the end of this pamphlet. The tables will help in the design of frost protection and floor heating systems.

A heated floor feels pleasant and comfortable and is suitable for all rooms. With floor heating, the heat producing area is large and surface temperatures are low. Floor heat-ing is a dream solution for an in-terior decorator, since the heating devices are not visible, space can be freely used and furniture placed creatively.

Floor heating improves floor surface drying where water has been used, and prevents moisture from entering a house’s structures. Night-time electricity can be used with storage floor heating.

Floor heating for all living quartersFloor heating is suitable for all rooms and spaces in a house: Ensto has the correct product for you! It’s just a matter of selecting your product according to room size, heating requirements, floor structure and floor material. Floor heating can be either direct or partial storage heating.

The Tassu floor heating cable for new buildings and renovations The Tassu floor heating cable is a reliable and long-lasting heating solution for both dry rooms and those high in moisture content,

direct floor heating being the best choice for the latter. Partial storage heating is used in rooms with high floor surface material heat resist-ance. Such materials include wood, vinyl mats and textile carpets.

StepMat heating cable mat for simple and clear spacesStepMat is a reliable heating cable mat, which is easy to install. StepMat is suitable for dry areas as comfort heating as for bath rooms. Its heating power is designed for normal living quarters, but there are also solutions for spaces with less insulation for concrete, stone or tile floors, where more heating power is required.

StepKit floor heating cable package for small and complex spacesStepKit, a heating cable ready for installation, forms an excellent addition to Ensto’s product range. It is ideal for renovating small and complex spaces. It can be used on all floor structures – concrete, wooden or plate structure – and is very easy and fast to install. This product is ready for installation. The package includes a tempera-ture-limited thermostat, 10-35 °C, making the product suitable for

installation in all floor materials, e.g. in a wooden floor structure.

Reliability year after yearFloor heating products are in-stalled permanently inside the floor structure. This makes floor heating extremely safe. Correctly designed and installed floor heating lasts for decades. Since product reliability must meet with expec-tations, the manufacturer does matter. Ensto is responsible for the quality of StepKit, StepMat and Tassu products for 10 years from the date of manufacture.

Pleasant and versatile floor heating

Efficiency is maximised when elec-trical heating is designed correctly, since most of the energy consumed is transformed into heat. Accurate thermostats react quickly to chang-es in temperature, saving energy and improving living comfort.

Wide, flexible product rangeEnsto’s wide heater product range offers both combination panel heaters and flow panel heaters.

Tupa heaters are very high-quality combination heaters for all living quarters where comfort, cosiness and safety are required. Heat is generated in the most pleasant way; some being radiated from the front surface and the rest used to heat convection currents. Product names in the Tupa series include Taso, Lista, Peta and Roti.

Opera heaters are modern and elegant. Flow panel heaters produce heat quickly and comfort-ably and are suitable for perma-nent dwellings, summerhouses and cottages. The product range includes models with electronic and

Heating with panel heater – comfortable heat efficiently

mechanical thermostats. Electrical connections are either permanent or by using a plug, both in dry and wet locations.

Beta heaters are a safe choice for summer-houses and cottages, these basic heaters being durable, reliable and easy to use. They are equipped with a plug and a me-chanical thermostat.

Safe, practical and easy to installThe heater surface temperatures are low, even below 60 °C. An internal overheating protection switches the heater off if over-heating should occur. As class II appliances, the heaters require no protective earthing. They are equipped with a power switch for turning heaters on or off indi-vidually. Connecting and installing these heaters is very easy: a wall bracket can be used to determine the locations of the holes to which the heater will be fixed. The con-nection box can either be fixed to the wall or used as the connec-

tion box lid, and the connectors are spring-loaded, so no tools are needed when connecting the heater to the connection box. When the heater has been installed, it can be tilted with the help of the wall bracket , which eases cleaning from behind the heater.

Accurate, elegant and durableHeaters equipped with an electronic thermostat are extremely accurate and completely silent. The thermo-stats are factory-calibrated to an accuracy of ±0.2 °C or ±0.5 °C for mechanical thermostats. Adjust-ing the temperature is easy and the thermostat can be recalibrated if necessary. The material used is hot-dipped zinc steel and durable polycarbonate, so these heaters do not rust and are suitable for use in harsh environments. Some of the heaters are splash-water proof (IP24).

When ceiling heating is used the heat is radiated downwards from heating elements located above the ceiling’s surface material. The radiated heat warms surfaces in the room: the floor, the walls, the furniture and its occupants. Owing to direct heat radiation, the tem-perature can be kept 1–3 °C lower than with other heating methods. This saves a considerable amount of energy. Ceiling heating is very comfortable and, as with floor heating, offers endless possibilities for interior decoration. The heating technology is invisible and does not consume space.

An option for a wide range of spacesTypical venues for ceiling heating are permanent dwellings, sum-mer homes, offices, kindergartens, hospitals and sport facilities. Ceiling heating is also suitable for damp places with a high moisture content, such as shower rooms and indoor swimming pool areas. Ceil-ing heating can be used as a direct heating method or to complement storage floor heating.

Teval ceiling heating elementCeiling heating is implemented with ceiling heating elements in-stalled above the ceiling’s surface material or panel, such elements converting electricity into heat. The heat is radiated through the ceiling material into the room. Element temperatures depend on the power per area, the ceiling material and the thickness of the material.

Ceiling heating – pleasant radiant heating

Essi radiant heatersCeiling radiant heaters are ideal for heating shopping centres, sports

facilities, showrooms, industrial plants and warehouses.

Accurate and fast heating control ensures even heating and warmth in a room. This also means saving energy and substantial cost savings. Accurate control reacts to solar radiation and the heat produced by the room’s occupants, decreasing the electrical power used. Heating control is best designed alongside the design of the rest of the house: the best way to find the optimal solution, for each and every need.

Thermostats control heating individually for each roomThe heating of each room can be individually controlled with floor, room or combination thermostats. Major part of the panel heaters have their own thermostats. It is easy to lower the room temperature with a home/away switch. When you are away for a longer period of time, you can save heating costs by lowering the room temperature.

Floor heating controlThe best choice for controlling direct and partial storage floor heating is the ECO10F thermostat, which keeps the floor temperature at the correct level. This thermo-stat has a 4 °C temperature reduc-tion, which can be used to decrease the room temperature when no one is at home. The ECO16FR combina-tion thermostat should be used for floor heating control in living quarters, such as bedrooms and living rooms. This thermostat has an adjustable temperature reduc-tion of 1–15 °C.

Optimal energy consumption through heating control

Ceiling heating controlTeval ceiling heating elements and Essi i radiant heaters can be controlled using the ECO10R room thermostat.

Air heat pump supplementing electric heatingAn easy way to save energy is to use an air heat pump, an efficient way of transferring heat into a house from the outside. The heat produced by the air heat pump is usually directed downwards, so floor surfaces are heated effi-ciently and storage floor heating is only needed when the outside temperature is very low. The air heat pump is highly efficient and it is an ideal supplement for electric heating. This pump produces heat energy equivalent to twice its own electricity consumption even when the outside temperature is -15 °C. Its efficiency is around four-fold when the temperature is +15 °C.

Ensto frost protection solutionsControllable frost protection systems keep footways, driveways, gutters, rainwater systems and water pipes functional regardless of the conditions. They are easy to use and extremely reliable. These systems pay themselves back in the form of saved maintenance costs. Safety is improved since footways do not become slippery and pipe damage is avoided since pipes do not freeze.

Frost protection is easy when using Ensto’s heating cables, and the system is durable and easy to maintain. These products are developed for harsh winter condi-tions in the north. Home owners are responsible for avoiding the formation of life-threatening icicles above footpaths, safety mainte-nance also including keeping foot-paths ice-free. Keeping gutters, driveways and entrances ice-free guarantees safety, regardless of weather conditions, while the use of electric frost protection sys-tems saves on cleaning costs. In addition, the surface materials of walkways and driveways wear less when frost protection systems are used. Problems such as dust formation in springtime caused by salt and sand become things of the past.

Freezing of rainwater systems causes leaks, which can lead to moisture and mould damage and damage to the building’s load-bearing structures. Rain water systems and water pipes can be prevented from freezing using frost

protection cables, ensuring their smooth operation even in very low temperatures.

No ice, even in very low temperatures

Designing heating systems

Heating system design is very importantExpectations and needs are the key issue when designing an optimal solution for electric heating. A good design eases work and saves costs at all stages of a project. All three heating methods should be compared, while the need for frost protection must also be remembered. The next section introduces three different heating solutions to aid design work.

16

Superior

The “Superior” heating solution maximises the warmth and cosi-ness of all living quarters. Air flows caused by temperature differences are minimised by combining floor and ceiling heating to keep tem-peratures as even as possible in all rooms. Temperature differences between the neck and ankles are kept as small as possible, and al-lergic reactions are decreased by minimising airflows. The selected main heating methods include both direct and partial storage floor heating. Direct floor heating is selected for rooms in which the floor material is highly conductive, for example ceramic tiling. Partial

storage floor heating is used in rooms in which the surface mate-rial is less heat-conductive, for ex-ample parquet flooring. The heat is stored during times when electric-ity is cheaper, and heat is released into the room during the daytime. In such rooms, ceiling heating is used to complement other heat-ing methods, ceiling heating being turned on when the room tem-perature drops below a predefined limit. Floor heating is used in store rooms and garages. This improves floor drying and heating appliances are protected from damage and scratches. Individual floor heating and room thermostats are used to control the heating.

Outside areas are kept free of ice to ensure the safe use of foot-ways and driveways in the winter-time. Factory-made Ulla heating mats are used in front of garages and on porches (please note that the mat in front of the garage is folded, its actual size being 2 x 2.5 meters.) The self-regulating Opti-heat cable is used in front of other entrances and garage plumbing, and frost protection is controlled with an ECO900 thermostat.

in a permanent dwelling with nor-mal insulation. The wardrobe has a cover-proof panel heater (Peta), which switches off if something falls onto it.

High

The “High” heating solution is not as versatile as the Superior. This solution is ideal for both perma-nent dwellings and summerhous-es. It combines different heating methods and achieves a cosy feel-ing by providing even, comfortable warmth.

This solution uses partial stor-age floor heating in the living room, where the floor surface material is parquet and does not conduct heat

well. Direct floor heating is used in the kitchen, the shower room, the utility room, the toilet and the entrance room. All of these rooms have floors made of ceramic tiles.

Low Lista panel heaters are used for balancing heating in the living room. Individual floor heating thermostats are used in each room. Bedrooms have silent combined panel heaters equipped with electronic thermostats, the calculated heating power being 25 W/m3, enough to cover heat loss

Medium

The “Medium” heating solution generates cosiness using standard panel heaters and floor heating in washrooms. This solution has all the components needed for sound, basic heating. It is suitable for per-manent dwellings, summerhouses

and cottages. The main heating method is based on panel heaters. The utility room and washroom are equipped with floor heating to max-imise comfort and for quick floor drying, while individual floor heat-ing thermostats are used to control the floor heating. Living quarters have silent, combined panel heaters equipped with electronic thermo-

stats, and the calculated heating power is 25 W/m3, for which window widths are also taken into account. The living room has low Lista panel heaters under each high window. A splash-water proof heater Roti is used in the toilet, and the clothes closet has a cover proof Peta heat-er. Opera flow heaters are used in the garage and in the store room.

Continuous floor heatingDirect floor heating is the correct choice for saunas, washrooms and bathing rooms. It is also suitable as the only heating method for areas in which the floor surface material conducts heat well (ceramic tiles for instance) or where the floor struc-ture is other than concrete slab.

If the floor has a concrete structure, direct floor heating is achieved using Tassu floor heating cable. This cable is fixed to the reinforcement mesh or fixing strip so that the spacing remains the same during casting. The output should be 70 – 100 W/m2, installation spacing 15 – 25 cm and the installation depth approximately 5 cm.

In plasterboard flooring, a layer of boards is placed under the Tassu S heating cable, and additional strips of plasterboard are attached to the first board layer, the cable being installed between these strips. The

grooves containing the heating ca-bles are filled with a mineral-based plaster. An extra-hard plasterboard is installed next, then damp-proof-ing and then the final floor surface material. The output should be 70 – 100 W/m2 and the installation spacing 9 – 14 cm.

If the floor has a wooden structure, a 3 cm air gap must be left under the floor’s surface material. The Tassu S heating cable is attached to a mesh on top of the insulation and located in the air gap, while the output should be 60 – 80 W/m2 and the installation spacing 13 – 15 cm.

When installing the heating cable on an old floor, the Tassu S heat-ing cable is installed on the old floor surface material using either a mesh or fixing strips. An adhe-sion layer must be added on top of the old floor to make an adhesion surface for the new plaster. Floor insulation must be sufficient to prevent heat loss. The heat cable

is installed in a 1 cm thick layer of plaster so that it is totally covered. After this, the surface is levelled out and the surface material installed on the even surface. The output should be 70 – 100 W/m2, installation spac-ing 9 – 20 cm and the installation depth approximately 2.5 cm.

If the room is small, a toilet or vesti-bule for example, the self-regulated Ella floor heating cable without a thermostat can be used. This heat-ing cable is a self-regulated cable with a polyolefin sheath. Its nominal voltage is 230 V and the connecting cable length 2.5 meters. The installa-tion depth for the Ella heating cable is 3 – 5 cm and the installation spac-ing 20 – 30 cm.

The StepMat heating cable mat is easy to install due to its adhesive surface lining. It is easy to spread the mat out evenly on the instal-lation surface, and it can be cut and trimmed, making installation easy on floors of all shapes. When required, the StepMat heating cable can be easily detached from the mesh. The heating cable is a twin core ending cable, so there is only one cold end connected to the connection box. A thinner casting, than required for traditional floor heating cables, is sufficient enough for the StepMat heating cable mat.

Sizing and installation of floor heating

Partial storage floor heatingPartial storage floor heating is used in rooms where the floor surface material has a high heat resistance. Such materials include wood, vinyl mats and textile car-pets. The heat stored in the con-crete slab by using cheaper night-time electricity is transferred into the room during the day. The con-crete slab mass must be sufficient enough for partial storage floor heating, something which must be taken into account when designing the heating system. The Tassu floor heating cable is used for partial storage floor heating systems. The output is 80 – 150 W/m2, the installation spacing 15 – 25 cm and the installation depth 5 – 10 cm. When partial storage heating is used, the need for complementary heating should be considered, e.g. using ceiling heating, panel heat-ers or a floor heating cable already installed.

Optimal comfort through the correct temperature To obtain maximum cosiness and comfort in living quarters, floor surface temperatures should be as following:

Wood and cork surface 23–27 °CVinyl mat 26–28 °CCeramic tiles or concrete surface 26–28 °CLaminate 23–27 °C

Things to note when installing floor heating• The floor heating cables must

not be installed under closets or similar fixtures.

• Tassu and Tassu S heating cables must be installed in material with equal thermal conductivity. The cable loops must not touch each other and the cable must not cross over itself.

• The heating cable may not be fed through an expansion joint or areas in which there is a risk of the slab breaking or the heating cable overheating (e.g. the distance to a wood-fired sauna stove or storage heating fireplace must be at least 50 cm).

• The suitability of the floor material for floor heating must be checked from the floor material manufacturer.

• Cable element lengths intended for floor heating must not be changed.

• A 300 mA RCCB (residual current circuit breaker) should be used- in all wash rooms- in living quarters if the floor

surface material conducts electricity (e.g. ceramic tiles)

• The bending radius of the ther-mostat (e.g. ECO10F) sensor protection pipe must be such that the sensor element can be replaced, if necessary. The sen-sor must be installed between the heating cables so that it does not touch the heating cable.

• The floor heating cable installa-tion spacing should be smaller close to windows, doors and areas where heat loss is greater.

• Concrete takes approximately 30 days to dry, while levelling plaster takes approximately one week.

Sizing and installation of ceiling heating

SizingHeat loss is calculated for each room and the power requirement determined. As a rule of thumb for determing output, use 25W/m3.

There are three widths and several lengths of Teval ceiling heating elements. The element power is 150 W/m2 and the number of elements required is rounded upwards.

Location of the elementsThe ceiling heating elements are usually installed with battens crosswise to roof trusses. Teval ele-ments are placed as close as pos-sible to the outer and window walls, the recommendation being less than 30 cm from the window wall.

Space for pipes and plumbing can be left between the element and wall. An element installed next to a window must be at least 90 cm wide. All elements are installed parallel to one other with the cable ends in line. Elements next to one another can be installed onto the same batten.

Things to notePorous ceiling surface materials, such as Haltex or Styrox (expanded polystyrene) must not be used. The ceiling surface material’s heat resistance must be lower than 0.13 m K/W• The heating element must be at

least 2.3 meters from the floor surface.

• The elements can also be instal-led in an inclined ceiling, when the inclination is less than 45 degrees and the element distan-ce from the floor more than 2.3 meters.

• The conductive parts of the ele-ments must be at least 10 cm from other conductive structures (e.g. air ducts, outer roof material)

• A heating element cannot be installed in a ceiling, if the moisture blocking material used is aluminium foil or some other conductive material.

• No electrical piping should be installed in the same location as the element.

• Overlapping boarding must not be used. The maximum gap size in the ceiling surface material is 6 mm.

• A 30 mA RCCB (residual current circuit breaker) should be used in damp areas.

Radiant heatersEnsto’s Essi i radiant heaters act like the sun. By radiating heat, and the radiated heat warms the sur-faces. The surface temperature of a radiant heater element is 380 ºC.

The Essi i radiant heater is a quick way of providing heat, so it is suitable for rooms which are not used very often. Using an Essi i, the temperatures in a room can vary (e.g. between work areas). When ceiling heaters are used, the room temperature can be kept 1-3 degrees lower than normal without affecting comfort and cosiness. Night-time electricity can also be used to store heat.

PositioningThe Essi i radiant heater should be installed onto a light fixture rail or the ceiling surface close to the outer walls (1-2 meters from the wall or a minimum of 0.15 m). The minimum installation height is 3.5 meters.

SizingThe calculated output for stores and industrial halls with normal insulation in Southern Finland is 100 – 120 W/m2 and in Northern Finland 120 – 150 W/m2. If heat loss needs to be determined accurately, it must be calculated separately for each space. To ensure an even temperature, the distance between two heaters must be less than the height of the room.

InstallationThe parts needed for suspending the heater are included in the pack-age. The heater can be fixed onto the light fixture rail or the ceiling

or hung from the ceiling. Standard installation fixtures can be found in the connection box.

Frost protection for outside areasIn most cases, Ulla cable heating mats present the easiest way to design and implement the frost protection and de-icing of outside areas. Frost protection can also be reliably performed using Tash series resistance cables or the self-regulated Optiheat15/30 heating cable.

To keep outside areas, such as driveways, pathways, ramps and entrances, ice-free using electric-ity, the heating cables are usually installed in sand or concrete under the surface layer. Melting power can be maximised by insulating the area from below.

Installation in sandFor the installation of Ulla mats or Tash cables, the sand’s granular size must be 0.063 – 2 mm . A thin layer of sand should be levelled by hand using a splint with a long handle. The splint edges should be rounded or protected by a piece of felt. Dam-age to the cable surface should be avoided. Be careful that the cable do not detach from the grid or move during levelling. A surface layer of asphalt, tiles or concrete should be added on top of the levelled sand.

Designing and installing frost protection systems

Installation in concreteBegin by tying the cable to the rein-forcement mesh with cable ties. The binding should be loose so that the cable is not damaged and the cable shielding is not exposed. The cable should be placed above the rein-forcement mesh to make trouble-shooting and repairs easier.

Installation is quick and the result reliable when factory-made Ulla mats are used: the installation spacing and the output will be even for the whole area. Ulla mats have an output of 300 W/m2, which is sufficient for most uses. If the area is covered and snow cannot reach it, 200 W/m2 is usually enough. An output of 400 W/m2 is recommend-ed for driveways and ramps with heavy traffic.

If the desired output is other than 300 W/m2 or if the factory-made Ulla mat is not suitable, then the Tash cable should be used. The resistance, length and installation spacing can be calculated accord-ing to the instructions at Ensto’s website, www.ensto.com.

Frost protection of stairs and steps can be performed either using the self-regulated Optiheat15/30 or the Tash series resistance cable. We recommend the single or dou-

ble conductor Tash cable for large staircases and the self-regulated cable for smaller ones. Frost pro-tection systems for outside areas should be protected by a 300 mA RCCB.

sensors and the controller are needed for frost protection of out-side areas: the snow and ice sensor (ECOA901) is installed outside the heated area and the humidity and temperature sensor (ECOA902) is installed within it. A snow and ice sensor (ECOA903) installed in the gutter and an air temperature sensor (ECOA904) are needed when controlling the frost protection of rainwater systems.

Controlling of frost protection systems

The frost protection of outside areas, rainwater systems and pipes should be controlled by a purpose built controller, since this will enable energy savings. A control system facilitates the use of cheaper night-time electricity for frost protection of outside areas. The ECO900 con-troller installed in the distribution panel board is used to control the frost protection of outside areas and rainwater systems. Two ground

A supplementary unit ECOA905 controller can be connected to the ECO900 controller. The ECOA905 facilitates the star-delta-connec-tion of the heating and monitors the condition of the heating circuit.

Frost protection of rain-water drainage systemsIn rainwater drainage systems, the heating cables are installed in the bottom of horizontal gutters in drainpipes and when needed in the rainwater drainage systems.

Design and installationThe self-regulating Optiheat15/30 cable is recommended for instal-lation in drainpipes so that a loop is formed in the pipe’s lower end. If the drainpipe is very long or if it has bends, one-way cabling is used.

If the drainpipe is located in the end of the gutter, the cable in the gutter should be extended so that it reaches the lower end of the drainpipe. Strain reliefs VP300 are installed in the top end of the drainpipes. In rainwater drainage systems, the heating cables must be installed below the ground’s freez-ing level. If this is not possible, other means must be used to ensure that the pipes cannot freeze at any point. The free flow of water throughout the whole system must be ensured.

The lengths of the horizontal parts and the heights and numbers of drainpipes should be calculated when designing a frost protection system for rainwater gutters using the self-regulated Optiheat15/30 heating cable.

A rainwater gutter 100 – 150 mm wide and a drainpipe of diameter 100 – 150 mm requires approxi-mately 30 – 60 W/meter of gutter. If the gutter is more than 150 mm wide, the calculated power is 200 W/m2 in normal conditions. If the

area is in sunlight during the day, the melted snow may turn into ice during the night. Snow melting due to poor roof insulation freezes during the night or if the water runs in the shade. These issues must be noted when designing the heating system. Allowed maximum heating power loads and maximum temperatures of gutters should be checked with the manufacturer. All rainwater gutters and pipes must be cleaned of leaves and other debris during autumn to achieve maximum benefit from the heating. If the system is not well cleaned, the heating cable’s condition might deteriorate, affecting the system’s operation. The cables of the rainwa-ter drainage system are protected by a 30 mA RCCB.

ExampleThe rainwater system has one horizontal gutter, of a length of 16 meters, and three drainpipes as per the drawing. The first and third drainpipe are 7 meters long and the second has more bends and is 9 meters long. The supply cable enters a junc-tion box near the second drainpipe and the distances from this junction box to the first and third pipe are 5 and 10 meters. The maximum in-stallation length of the Optiheat

Frost protection of water pipesAll pipes and plumbing for a house should be protected with heating cables to prevent problems and damage caused by freezing. A variety of products suitable for frost pro-tection of pipes are available from Ensto’s wide product range. The maximum power of a heating cable inside a plastic pipe is 10 W/m. Self-regulated cables with more power or multiple cables, can be used in larger pipes. The heating power can be higher in metallic pipes. In addition, self-regulated Optiheat25 cable or the Tash series resistance cable can be used. When the cable is installed inside a pipe it lies on the bottom of the pipe. If the supply runs from the top of the pipe end there is no need to fix the cable end in any way. When the supply comes from the bottom end of the pipe, you should fasten the cable end to prevent it from moving. The self-regulated Optiheat cable or the factory-made Plug’n Heat element equipped with a Euro plug can be used when the heat-ing is installed inside a water pipe. The Optiheat9 and the Plug’n Heat heating cables have fluoropolymer sheaths and are tested for use with food so they can be installed also inside drinking water pipes.

The heating cables are installed in the pipe with a pressure resist-ant lead-through EFPLV 1. The maximum installation length of an Optiheat cable is determined by the installation method and the switch-on temperature of the heating cable (see the table on page 42).

When the heating is being used to prevent water meters and pipes from freezing, the self-regulated Optiheat cables should be installed according to the drawing.

When the plumbing work has been completed, frost protection can be easily performed using the Plug’n Heat element equipped with

a Euro plug. If the cable is installed on the pipe surface, it can be fixed with heat resistant LT20 tape round the pipe and the heating cable at intervals of approximately 30 cm. Contact between the cable and pipe must be ensured. To even the temperature the cable can also be attached with ALU50 aluminium tape, parallel to the pipe. The SV10 galvanised mesh can also be used for fixing the cable. The heating cable should not be installed to the bottom of the pipe, but slightly to one side in accordance with the drawing. The easy-to-use ELS-2000 thermostat is best suited for controlling frost protection of pipes. When the heating cable is installed inside the pipe, the sensor should be installed near the top of the pipe. If the heating cable is on the outside of the pipe, the sensor should be installed on the opposite side.

Tash heating cablesTash series resistance cables are generally used for frost protection of outside areas. They can also be used for frost protection of long pipes and for floor heating in industrial halls. These cables must be protected against mechanical stress. Ensto supplies both single and twin-conductor cables.

Optiheat heating cablesThese self-regulated heating cables are used for frost protec-tion of rainwater and drinking water pipes, roofs and rainwater drainage systems. They can also be used for frost protection of stairs and for floor heating of small areas. The output of self-regu-lated cables changes as conditions change. Since the cable attemps to keep the conductor tempera-ture constant, the cable output increases wherever more heat output is required. The output per length unit is not consistent, since the power changes according to the conditions along the cable.

Self-regulated cables can be cut to desired length, but always adher-

ing to the maximum installation lengths. When sizing fuse protec-tion for self-regulated cables, the variation in output according to temperature must be taken into account. The heating cable current will be large when it is switched on in cold circumstances, but the current will decrease as the cable warms up. If the fuse is underrated, it will blow. Size the protection according to the lowest operating temperature! Protection device for graph C.

Using the tablesPipe heat loss tableA safety factor of 1.3-1.5, is added to the table values. The heat loss table indicates how much power is needed per pipe meter to keep the water from freezing.1. The first column is the pipe outer

diameter2. The second column is the

insulation thickness3. The following five columns

20 °C - 60 °C are the temperature differences between the pipe and the surrounding air. If you want to keep the water from freezing and the outside temperature is - 30 °C, you must select the 40 °C column. The insulation heat conductivity used is 0.035 W/mK.

(Stone wool +10 °C)

ExampleThe plastic pipe outer diameter is 48 mm, the insulation thickness 50 mm and the temperature differ-ence 35 °C. The calculated heat loss is 7.8 W/m. The safety factor se-lected is 1.4, so the calculated power equals to 7.8 x 1.4 = 10.92 W. Since the allowed maximum power of the heat cable per meter for plastic piping is 10 W/m, the Optiheat10 should be selected.

Tash cable tablesThe maximum installation lengths for certain loadings per meter are indicated for each cable. The table also indicates the heating power per meter. Values are measured for supply voltages 230 V and 400 V. For instance, the table can be used when determining which Tash heat-ing cable is suitable for defrosting a certain pipe or an outside area.

ExampleAn outside area (7.5 m2), with a selected defrosting power of 350 W/m2. The total power is 2625 W. The cable is installed in concrete, so the maximum power is 30 W/m. The table indicates which cable should be used to achieve the desired power with 30 W/m. The Tash 0.21 is suitable when the length is 95 meters and the total power is 2652 W. The heating power per area is 354 W/m2 and the installa-tion spacing 8 cm. The cable is fixed to the reinforcement mesh with cable ties or with the PPN6 installation strip.
