Reclaim C02 hot water heat pump

FAQs about CO2 Hot Water Heat Pumps

What is a CO2 heat pump?

Heat pump water heaters absorb warmth from the air, amplify it and transfer it to heat water. Therefore, they are also referred to as ‘air-source heat pumps’. Heat pumps use electricity to operate the compressor rather than heating an electric element. Because of this a Reclaim system is nearly five times more efficient than a conventional electric water cylinder with an electric element. They save energy, save money and reduce greenhouse gas emissions from electricity generation. Find out more about how a CO2 heat pump works.

Why are CO2 heat pumps better for the environment?

Because they use the latest developments in refrigerant technology, highly efficient and natural CO2. The best heat pumps available have the highest co-efficient of performance (COP).  Reclaim for example has a COP of 4.7.  Less energy use reduces the environmental impacts from the electricity generation. Since CO2 is a naturally occurring gas there is no need to burn fossils fuels.

Will it work when the weather is colder?

Yes, in fact Reclaim CO2 heat pumps work extremely well in even very cold weather.  Due to the unique properties of natural carbon dioxide (CO2) as a refrigerant at 1°C a Reclaim heat pump still provides more than four times as much energy output as electricity in, saving 75% of power use compared to an electric element.

At minus 5°C there is almost 3 times as much output as input.  And at an incredible minus 10°C you will get 2.4 times output for electricity it uses.

Do frosts affect the Reclaim heat pump?

Once the temperature drops below freezing the heat pump will need to do occasional defrost cycles to free the fins of ice.  The energy needed for this is included in the savings calculated above, so high performance is maintained throughout.

Are CO2 heat pumps noisy?

The Reclaim CO2 heat pump is the quietest system on the market with whisper quiet functionality – average noise level: 37 dB.

Can I replace an existing gas hot water system with a CO2 heat pump?

The gas system is easily replaced because the Reclaim CO2 heat pump and its cylinder require the same services as the gas hot water heater – cold water in, hot water out, plus an electrical connection.

Can I combine is with a PV Solar system?

Combined with your PV system a Reclaim CO2 heat pump will optimise your investment, multiplying your savings on hot water five times and avoid exporting to the grid for little return with low buy back power tariffs.

I don’t have room for a hot water cylinder in my house can I still use this system?

The Reclaim CO2 heat pump allows for both indoor or outdoor cylinder installation, meaning you do not need extra room to fit it in your home.
