Once a year. In many cases this is necessary to keep the warranty valid.

No, a ground source heat pump operates from the thermostats in the house. If you set the temperature at 18 °C and the temperature in that room drops below, a signal will be sent to the ground source heat pump which will deliver heat until the thermostat is satisfied. Many ground source heat pumps can now be operated remotely using a phone or computer.

Yes, in some cases you may need a larger heat pump because the properties heat loss is higher that a newer property but this will be determined on the heat loss report. If your property is very old and drafty it may be better to have some other energy saving methods put in place before a heat pump is installed we can advise you on this.

Co-efficency of Performance. This refers to the heat pumps levels of efficiency, a good example would be electric radiators which have a COP gets 1kW of heat for every 1kW of electricity. In the case of a heat pump it is more like 1kW of electric for 4 kW of heat. Electric radiators are 100% efficient whereas grouns source heat pumps are 400-500%. 

The SPF seems very similar to COP but it is the heat produced by the ground source heat pump. It’s less about the electrical input which doesn’t qualify as renewable heat.

Often done by using an immersion, the hot water sits in the tank at 50 °C and therefore needs to be taken up once a week to over 65 °C to kill any bacteria in the cylinder.

Ground Source Heat pumps have been running for over 20 years. Servicing your heat pump regularly helps ensure it continues to run smooth and efficiently.
