Does anyone know if the green-deal assessment gives a figure of the number of kWh a house will need to be heated by a (biomass) boiler annually, or does it state the size of the boiler that is required?
And also, how do I know how many hours my system will be running for?

The reason for asking is I'm looking at online calculators and figures for a biomass boiler and some calculators ask for a size of boiler and multiply the figure by 1314 to get operational hours (on which payments are made) and some ask for size of boiler and number of hours it will be running for.....which I assume the GD assessment won't tell me about.

Enlightenment is much appreciated.

The EPC gives the heat demand for space heating and hot water. The GDA gives estimated financial costs and potential savings.
RHI payments are based on renewable heat used and not influenced by operating hours, have a look at

Schuco solar hot water - 3300kWh/annum, 16 BP 4175N PV panels - 2.8kWp, log burner and back boiler and 18 Ying Li 235 PV panels - 4.2kWp, 42kW ground mount PV, 9kW Panasonic ASHP, 40kWh Nissan Leaf
