Electric heating is considered 100% efficient. Where this looks good
initially, it is actually pretty poor when you compare it to Air or
Ground source which are approx. 400% efficient, so four times more
efficient than electric. The more efficient your heating system is, the
lower your running costs are.
Our initial survey will give a very good estimate of return on the RHI which will then be confirmed by the Energy Performance Certificate (EPC) that is required in order to claim the RHI. The Energy Performance certificate must be no more than 2 years old.
An example of how the RHI is calculated is below:
Page 4 of your Energy Performance Certificate will detail estimated Space heating and hot water to be used over the period of a year, e.g.:
From these figures, a calculation will be made to show how much renewable heat will be generated to satisfy the demand.
The Renewable Heat Incentive is the amount paid to you from the government for having a renewable heat source installed instead of using fossil fuels.
A typical calculation would be both Air Source and Ground Source:
