home and garden indoor environmental qualityHow do air to water heat pumps work?
Last Updated: 5th February, 2020
An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. An air-to-air system produces warm air which is circulated by fans to heat your home. They are unlikely to provide you with hot water as well.

Accordingly, how efficient are air to water heat pumps?
An air to water heat pump typically costs 50% to 60% less to heat your home than a tradition fossil fuel system such as an oil or gas boiler. Put simply the 'efficiency' of an air to water heat pump is from 320% to 400% or more where as even a condensing boiler has an efficiency of only 92%.
Similarly, are air source heat pumps expensive to run? The reduction in air source heat pump running costs would be of only 3.5% in comparison to a gas boiler. If you're using the heat pump to produce DHW as well, your running costs will increase. As stated above, when the ground-source heat pump is used for space heating only, the running costs are reduced by 52%.
Additionally, what is the best air to water heat pump?
According to the test result, Thermia Atec is the heat pump that delivers the biggest overall savings. Moreover, Thermia Atec has top results in terms of hot water temperature, low noise levels and low energy losses. The test results in brief – Thermia ATEC: Has the highest annual efficiency.
What temperature is a heat pump not effective?
If you are impatient, I won't make you wait; heat pumps don't work well below 25-30 degrees Fahrenheit. But what you might not know is that the heat pump temperature range is broader than most people think, and with the addition of supplemental heating it can work even in the chilliest of temperatures.
