Since 26 September 2015, all new heat pumps must be sold with an EU product label. It states how energy efficient the pump is on a scale from dark green (most efficient) to red (least efficient). Heat pumps must have an energy label on them. Check that any grills are free of leaves and debris on a regular basis and follow any other maintenance checks advised by your installer. You should also have your heat pump serviced every two to three years. Your installer should show you how to control your heat pump system. Often you'll need to set your heating to come on for longer than with a traditional system. To get the best from your heat pump, you'll need to know how to use it most effectively. For example, the figure will be higher if you are replacing coal or an oil boiler rather than natural gas.Ī heat pump needs a power source, usually electricity, to power the heat pump, so there will still be some resulting CO2 emissions. How much CO2 you'll save depends on the fuel you are replacing. Electricity is needed to drive the pump so they're not zero-carbon (unless the electricity comes from a renewable source such as solar panels or a wind turbine).Īn air source heat pump system can help to lower your carbon footprint as it uses a renewable, natural source of heat – air.Condenser units can be noisy and blow colder air into the area immediately around them.You'll need enough space in your garden for the external condenser unit.You could save money on heating compared with some older systems.Less disruptive than installing a ground source heat pump, especially if you're retrofitting.Energy efficient and low carbon - air source heat pumps generate less CO2 than many conventional heating systems.Here are some of the key advantages and disadvantages: Pros It can also cost less than retrofitting underfloor heating later on.Īir source heat pump advantages and disadvantagesĪir source heat pumps require little maintenance and can provide heating and hot water, but they aren't flawless systems. It is more straightforward to incorporate larger radiators or underfloor heating for a heat pump while you're extending your home or in a new-build property. To be most effective they need a large surface area to release the heat. They're most suitable for larger radiators or water underfloor heating because the heat they produce is cooler than that from a conventional gas or oil boiler. Air-to-water heat pumpsĪir-to-water heat pumps take heat from the outside air and feed it into your wet central heating system. They work in different ways and are compatible with different types of heating systems. There are two main types of air source heat pumps: air-to-water and air-to-air. Their size depends on how much heat they'll need to generate for your home - the more heat, the bigger the heat pump. They absorb latent heat from the outside air and use it to increase the temperature inside your home.Īir source heat pumps look similar to air-conditioning units. Our independent switching site, Which? Switch, will help you to find a cheap energy deal.Īn air source heat pump is a low-carbon way of heating your home. Make sure you're not paying too much for gas and electricity. Read on to find out more about the pros and cons of air source heat pumps, so you can decide whether getting one is the right decision for you. Other options to generate your own heat include: But remember, a well-insulated home is essential – otherwise the heat the pump is generating escapes more easily. Heat pumps can save you more on your heating bills if you're replacing an expensive system such as electric storage heaters, oil, LPG (liquefied petroleum gas) or coal, rather than gas. So you'll need to run them for much longer periods to heat your home to a comfortable temperature. They deliver heat at lower temperatures than gas and oil boilers. It will enable you to generate your own renewable heat and potentially save money on your energy bills. An air source pump is an alternative way to heat your home.
