Does anyone know which mathematical formulas are used to calculate heating requirements in a house?
I need to work out a figure, in KW/h or BTU, taking into consideration:
i) total volume of all rooms & corridoors to be heated
ii) daily hot water requirement
iii) number of radiators
iv) insulation in house, or lack thereof
Thank you in advance xx

Use this, get your toal heating requirements, add hot water 6-8 kw if a conventional boiler, not if a combi. Add 15%-20% and get a boiler to match, Condensing boilers have to run at load to be efficient, so allow for that in any calculations.

A rough guide is to allow 5000btus for each radiator, and add on 10000 for the hot water. hope it gives you an idea how big a boiler you need.0

simple answer is to go to your local plumbing or central heating supplier and ask them to work it out for you , if they think there going to get sale they will be very helpful
