Bring invisible warmth into your home

As fuel costs continue to rise, even the most efficent modern gas boilers struggle to turn £1 of gas into more than £0.90p of heat in your home.

But with heat pump technology you can triple the heating value of your spend on fuel.

Heat pumps can convert each £1 of fuel into £3 or more of heat, tapping into the hidden warmth that surrounds us and bringing it into your home.

Teamed with gentle radiant heat from underfloor heating, your home can have a totally different kind of incredibly efficient warmth.

Thinking about installing a heat pump?
The read our quick guide to the advantages and disadvantages of heat pumps.


Traditional central heating relies on burning gas to heat up water, then circulates the water around your home into radiators that give out heat to your rooms.

Instead of burning fuel directly to create heat, heat pumps extract energy from the heat that exists all around us and use it to warm our homes and heat up domestic hot water.

There are two main types of heat pump. Those that extract heat from the air and those that take it from the ground.

Each type of pump has its own advantages and disadvantages (more about these later), but both types work incredibly efficiently, typically turning each £1 you spend on fuel into £3 or more of heat.


Heat pumps absorb solar energy trapped in the air and in the ground.

Even on cloudy days, heat from the sun warms the air and the ground (particularly the ground where, below the surface, the temperature remains warmer than above-ground even in winter).

We can tap into these heat sources using technology to harness the warmth they contain.


There are two types of heat pump - air to water and ground to water, known respectively as 'air source' and 'ground source'.

Air Source Heat Pumps

These work by taking the principle of the refrigerator and turning it inside out.

In a refrigerator, a special gas is pumped through pipework around the shell of the fridge. The gas absorbs heat from inside the refrigerator then disperses this heat into the surrounding air at the back of the fridge.

As a result, the refrigerator is cooler inside than it is outside.

With your home, an air source heat pump takes heat from the outside air (even on a cold day) then transfers this heat to water so the heated water can be pumped around your home, creating a warm home and providing hot water.

Ground source heat pumps

In ground source heat pumps, warmth trapped underground is absorbed into water circulating through underground pipes and this warmed water is then brought to the surface.

The heat energy in the warmed water is transferred to water circulating around the home to provide warmth and to heat up domestic hot water.


Because the source of heat is free (energy in the air or the ground), a heat pump is an extremely efficient way of creating warmth.

The main operating cost of a heat pump is the electricity used to pump the heat source (air or water) into the heat pump and the heated water around your home.



The key advantage of heat pumps is their operating efficiency - typically £1 of energy put into the pump generates £3 or more of heat energy for your home.


Heat pumps are currently more expensive to buy and install than traditional boilers.

The higher installation costs have to be taken into account when considering the benefits of choosing a heat pump over a traditional gas fuelled boiler if your home already has a mains gas supply.

If you can't connect to mains gas then heat pumps become much more attractive in comparison to the alternatives of oil or LPG due to the installation costs of fuel storage and a boiler.

In addition, heat pumps are eligible at the moment for financial incentives which can help with installation and running costs.


Typically, heat pumps produce heated water at around 45-55oC, fine for underfloor heating, but below that required for traditional radiator based heating and for providing domestic hot water.

As a result, whilst radiators can still be used with heat pumps they need to be bigger than normal to provide enough heat to a room.

This is because the surface temperature of a radiator on a heat pump system is lower than in gas powered heating.

Also, the temperature of the domestic hot water provided by a heat pump needs to be boosted by a secondary heat source (such as an immersion heater) to make it usable.

The hot water storage cylinder temperature also needs to boosted regularly to around 65oC to prevent the growth of Legionella bacteria in the cylinder.
