Quick look at our latest RHI results
During the period Oct- Dec 2014, our heat pump produced 5137 kWh of heat. The cost of electricity to produce this heat was £113.99. Which equals 2.2p per kWh. The Renewable Heat Incentive payments generated during this time was £369.86. As a result this means we have effectively been paid £255.87 to heat the Heat Collector offices (150sqm).

Daily Data
Here we record the daily readings from the heat pump installed in the Heat Collector offices. As an MCS accredited installer, we think its important to have an installation that the customer can come and see. This page is updated daily and shows how much heat has been produced, how much electricity it’s taken to produce it and the perhaps most interesting of all, how much cashback from the government RHI is due each day. As it is a non domestic installation we get 8.7 pence per kWh for the next 20 years, if it was domestic it would be 18.8 pence per kWh for the next 7 years. (Have a look at our RHI page for a full explanation of how it works)

Thats a load of data! Confused?
Dont worry! Heat pumps are quite simple but sometimes the data is confusing. Lets explain a few of the fields in the table above that sometimes cause confusion!
Electricity Used
Is just that, how much electricity it has taken to run the heat pump, the kilowatt hour, or kilowatt-hour, or symbols kWh, kW·h, or kW h, or unit is an amount of energy equal to what it takes to run 10 x 100 watt light bulbs for one hour.
Heat Produced
This is how much heat has been produced from the heat pump, just like electricity this is measured in kilowatts (kWh). The Government Renewable Heat Incentive (RHI) Scheme currently pays back 18.8p per kWh on deemed usage for residential properties & 8.7p per kWh for Tier 1 usage on commercial properties. The current schemes are running for 7 years and 20 years respectively.
What it cost to heat the building
This is the total amount it has cost us to run the system. Electricity is used to run the heat pump and cirulating pumps. In the table you can see how many kWh it has used per day.
What it would cost if we used other fuels
Here we work out how much it would have cost to produce the same amount of heat using the other types of fuel to heat the building to the same level as using the heat pump.
Non Domestic RHI generated
A heat pump operating at COP (Coefficient of performance) of 3.5, provides 3.5 units of heat for each unit of energy consumed (i.e. 1 kWh consumed would provide 3.5 kWh of output heat). We designed the system in the Heat Collector offices from the ground up with the view of maximizing the COP, as a result we are currently running at 6.2 or 620% efficiency!.
