Heating The Energy Conscious Home
Twinning Low Mass Heating Solutions with Heat Pump Systems
Saving Energy; Heating Better!
Jaga manufactures a range of high quality wall-mounted, free standing and in-floor heating solutions. These are increasingly viewed as an attractive, responsive, energy-efficient alternative to under-floor heating for use in heat pump systems.
At the heart of all Jaga products is the company’s patented Low-H2O technology. A Jaga radiator with Low-H2O technology weighs only one tenth as much as a traditional steel panel radiator and contains 90% less water. This means that it has an extremely low thermal mass. Allowing it to react much faster. And deliver heating exactly when, and only when, it is needed with proven energy saving for the home owner.
By contrast, high mass systems cannot react appropriately to save energy due to their sheer thermal inertia.
In fact in testing carried out by the Building Research Establishment (BRE), Jaga Low-H2O radiators were proven to react three times faster to fluctuations in temperature than traditional high mass steel panel radiators and reduce fuel consumption by 10%. Thereby reducing CO2 emissions and setting a new standard for sustainable heating.

Small But Powerful
Listen to most under-floor heating manufacturers and you might be forgiven for thinking that under-floor heating, and only under-floor heating, will work with heat pump systems because of its lower flow temperatures.
Or that if you insist on traditional radiators – which normally have a flow and surface temperature of around 80°C - you have to use unfeasibly large models to achieve a comfortable output when working with the typical 35°C to 45°C water temperatures obtained from heat pump systems.
Jaga’s patented Dynamic Boost Effect (DBE) works in harmony with the Low-H2O heat exchanger to deliver maximum output from much smaller radiators.
Actually today’s reality is very different. A radiator featuring Jaga Low-H2O heat exchanger fitted with a DBE system is designed to deliver up to 250% more heat output than normal radiators.
The result is a smaller radiator that takes up less wall space yet provides optimal heating performance even at water flow temperatures as low as 40°C – the sort of flow temperatures of course that are produced when using ground source heat pumps or other low energy systems.
In a DBE powered system, it is actually a microprocessor controlled unit that intelligently regulates the speed of the incredibly quiet thermal activators to ensure that the correct level of heating is delivered at all times to achieve and maintain a comfortable temperature. This microprocessor which is in effect the DBE’s “brain” works on 12 volt DC. Even during the few minutes each day when boost mode might be employed - such as when switching from night to day or during periods of extreme cold, electricity use is lower than a TV in standby mode.
Critically too, DBE equipped Jaga radiators have been found to warm a room up 9 times faster than a steel panel radiator with a comparable output.
The output and speed of DBE also cuts the length of the heating periods to a minimum, meaning a reduction of 15% - 25% in heating bills for an average home.

How do I select a DBE radiator?
There are three outputs for DBE radiators: standby, comfort and boost. Sizing a radiator based on the comfort mode means you will have smaller radiators which also ensure faster warming up and greater comfort.
The outputs are as follows:
StandbyThe DBE is in standby but is not working. The normal static capacity of the Low-H2O radiator, without the assistance of DBE is sufficient to keep the room up to temperature.
Comfort (automatic)If the DBE measures too low a room temperature it automatically switches to comfort mode. In this mode it will accelerate heating by gradually increasing the capacity relative to the measured temperature up to a maximum of 150% of the static capacity.
Boost (manual)When you press the boost button the DBE will provide maximum heat emission for approximately 15 minutes. The capacity increases to 250%. This means that an unheated room can be heated up in no time.
The Jaga DBE rangeThere are a range of different Jaga products available that are the ideal partner for heat pump systems and these include the options on the following pages:

Free Standing
Knockonwood DBE
As an alternative to trench heating, the Knockonwood Freestanding DBE is small and compact yet offers powerful heating performance.
Height: 21 cmLength: 110 - 130 - 170 - 210 cmOutput: 1178 to 4106 watts
Mini DBE
This slim and discreet solution is surprisingly powerful and produces a curtain of heated air for use in front of large glazed areas to banish cold downdraughts and condensation. The Mini DBE can also be used as the primary heat source in virtually any room.

Key Advantages of Jaga DBE Heating
In the UK, there is now a strong move towards alternative technologies that are sustainable and environmentally much more acceptable. The Ground Source Heat Pump Association have calculated that 40% of CO2 emissions are derived from the heating of buildings.
By using renewable sources of energy to heat a property you can help to reduce these emissions, particularly when compared to burning fossil fuels such as oil.
Most electricity suppliers are now offering ‘clean green’ electricity from a renewable energy source. If a self-builder or homeowner were to use this to power a heat pump running Jaga DBE radiators or in-floor heating solutions, the property would be totally heated from renewable energy with zero carbon emissions.
