I've done the Myson heat loss calculation and the heat loss is 13840 W. The calculation tells me I need a boiler output of 22.55 kW.
The B&Q "Installing a gas fired central heating system" leaflet says just add 10% to the heat loss to calculate the required boiler output.
Why the 63% extra for the Myson calculation?
Wickes rads seem fairly cheap. Anyone know of a better source with discounts for bulk?
Thank you,
Neil
