The Energy Saving Trust, at the end of its recent report which followed a study of 83 Ground Source, and Air Source heat pumps provided a list of consumer guidelines – something I’ve been looking for, for a long time. The trouble with everything else I’ve read is that it comes from a source with a vested interest. Here’s the list:
When you should consider a heat pump
- In a well-insulated existing property off the gas network. Heat pumps have the potential to reduce running costs compared with oil, direct electric, LPG, or coal, and can provide substantial carbon savings over the lifetime of the installation.
- In new-build properties
How to get the best performance from a heat pump
- Make sure that your home is as well insulated as possible (with. cavity and loft insulation) before installing a heat pump.
- Install the heat pump with low temperature under- floor heating or properly sized radiators.
- Insist upon understandable, user-friendly controls.
What to expect from a heat pump
- Since heat pumps provide a lower temperature heating than boilers, radiators will feel warm rather than hot.
- A house with radiators may heat up more slowly.
- The heat pump will run for longer hours than a conventional boiler, but if properly controlled it will switch on and off with the heating requirements of the house.
- A properly sized and installed heat pump should be able to provide all of a household’s domestic hot water, but many systems are installed with a supplemental electric immersion heater.
What to expect from a heat pump installer
Potential customers need to ask the right questions when choosing a heat pump, as with any other heating technology. Proper installation is essential to achieve the best performance from a heat pump.
- Ask the installer to explain how he or she has determined the appropriate type and size of heat pump for your property. The installer should explain how the heat demand of your property was calculated.
- Make sure the installer explains how the heat pump will work with your existing heating system (including radiators and hot water supply).
- Ask for guidance to operate the heat pump system controls.
- Ask how often you should run the heat pump.
Finally, the Energy Saving Trust recommends that householders speak to one of our advisors before installing a heat pump. Additionally, customers should speak to MCS accredited installers and manufacturers to determine whether a heat pump is a viable option.

This is a great comprehensive checklist, I’ve experienced great deductions in costs! If you’re doing more research into the various heat pumps available have a look at the different heat pump ratings and efficiency factors. Great article!

Every home is as individual as its owner. The key to selecting the right size heat pump for your home is an accurate estimate of the heat that will need to be transferred into your home in winter for heating, and out of your home in summer for cooling.
