Energy Summary
- Ground source heat pump
- Greenskies solar panels
- Greenstar 12i System boiler
This property demonstrates Worcester products which can either work individually or together. For the moment the hot water and heating for this property being used by the occupants is being generated by the Ground source heat pump.
The Energy House has a Greenstore combination ground source heat pump installed which provides heating and hot water for the house from one combined unit. Also installed in the Energy House is a Greenskies solar package together with a Greenstar system boiler. This combination also provides heating and hot water for the house. We are running one system at a time so that we can gather information on each one with the same heating and hot water demands from the homeowners.
What do the figures mean?
The letters kWh are an abbreviation of kilowatt hour and this is a measurement of energy. Your energy supplier's bills will show the amount of energy used in kWh and also how much they charge for each kWh. You can use this information on your energy bills to work out the benefits of renewable technologies, A-rated appliances, and the effect that SAP ratings have on the energy usage of your property.
The figures shown represent data taken in a typical week at the Energy House.

(1) Energy provided by the solar panels to the hot water tank which would otherwise have been supplied by the heat pump (2) The average amount of time the panels have been supplying energy to the hot water tank each day. (3) This shows the percentage of energy supplied by the solar panels to the hot water tank. (4) Total electrical energy used by the heat pump to extract energy from the ground (5) The COP is a measure of the efficiency and performance of the heat pump. This is the ratio of the useful heat energy produced by the heat pump compared to the electrical energy used to run the heat pump (6) Energy from gas used by the boiler to heat the house (7) Energy from gas used by the boiler to heat the hot water (8) Total energy provided (9) Energy from gas used by the boiler to heat the hot water tank. This energy is used by the boiler to supplement energy from the solar panels.
