husky air source heat pumps

Will a heat pump heat a home without the need for a

backup heating system?

The simple is yes! Provided the heat pump has sufficient

capacity for the demand and the installation itself is

designed and installed correctly.

Will the heat pump provide enough hot water?

Husky heat pumps can achieve hot water up to 60˚C and

heat 150 litres in only 20 minutes. This is when our pumps

are combined with our unique heat transfer hot water

cylinder.

Is a buffer tank needed?

The answer is yes! It is possible to install without a buffer

tank (although efficiency and life expectancy of unit will

lower), however it is important to consider the following:

Imagine your home in the winter. It’s -5˚C outside and the

heat pump is working hard. All air source heat pumps will

need to defrost on a regular basis at these temperatures.

During defrost, the heat pump stops heating the home and

actually takes heat from the home to perform a reverse

cycle defrost. If there is no buffer, the house will begin to

get colder and colder during this period. If however a

buffer tank is installed, this will continue to feed the home

with heat during the defrost cycle. It is simple logic. Some

installers insist it isn’t a problem without a buffer tank. We

do not agree.

If a heat pump is oversized, is it less efficient?

No! It is a common misconception that air to water heat

pumps will be less efficient (if oversized for the heat load

of the property). Actually logic tells us it would be slightly

more efficient if the unit was oversized. As long as there is

enough water in the buffer tank per KW output, the heat

pump will not multi-cycle, a common cause of inefficiency.

In the case of when it’s cold, an oversized unit will defrost

less than a perfectly sized unit meaning efficiency levels

will be slightly higher with an oversized heat pump.

Therefore whether the unit is perfectly sized or oversized,

the efficiency levels will be rather similar as long as the

design and installation is performed in the right way.

Does the Air Source Heat Pump work all year round?

Our system performs in temperatures as low as minus

20˚C. So the answer is yes!.

Will I need to install larger radiators in my home?

Possibly. If your current heating system is a condensing

boiler, if installed correctly, they only condense when

producing hot water below 60˚C. A heat pump will provide

virtually the same heat as this. However it is important to

note that the lower temperatures the heat pump

produces, the more efficient the system. Therefore having

oversized radiators is of benefit. Our engineers will

measure the heat output of your radiators for each room

and advise you accordingly.

How much annual maintenance is required on an Air

Source Heat Pump?

Generally, no annual maintenance is required. However it

is advisable to check it once a year for dirt, leaves etc. We

will show you how.

Where are Air Source Heat Pumps located?

We choose a suitable place outside your home. This can

be anywhere suitable on your premises.

Will it provide enough hot water for baths showers etc

and heating?

With the correct design (which we provide free of charge),

our heat pumps will provide everything you need.

How much hot water is produced each day by an Air

Source Heat Pump?

Hot Water is stored and made available in a pressurised

cylinder allowing for ample daily usage requirements.

Do Air Source Heat Pumps require single phase or three

phase electrical supply?

Air Source Heat Pumps can be powered by both types of

supply within the Voltage parameters of the building.
