Ground source heat pumps are a great eco-friendly way to generate heat for your home, but there are ways to ensure that they run efficiently. Follow this advice to make sure that your ground source heat pump is saving you money on your energy bills.
Set your immersion heater
One of the reasons your ground source heat pump could be using a lot of electricity is if your immersion heater is set to the luxury setting. A heat pump usually heats water to 40 or 45 degrees, but if you set the immersion heater to luxury it will boost the temperature to about 50 degrees. The immersion heater in a ground source heat pump is a backup and comes on when the pump can’t get the water up to the right temperature, which can happen if it’s very cold. There shouldn’t be much need for the water to be set to 50 degrees usually.
Monitor your heat pump’s electricity usage
If you’re worried about the amount of electricity your heat pump is using, ask your ground source heat pump engineer if they can attach energy monitoring equipment to the circuits that power the heat pump. Then they can monitor it over a number of weeks and see whether they can identify a pattern where the amount of electricity being used increases. If there is a spike in electrical consumption, they can work out ways to minimise the amount of electricity it uses.
Check that your ground source heat pump is big enough
If you find that your immersion heater is coming on a lot of times during the day, it could be because your heat pump is too small for your needs. The bigger your house is, the bigger your heat pump needs to be. If it’s coming on multiple times a day, it’s going to cost you more in electricity.
