### Correct Boiler Size (Kw) - MyBuilder

It's always best to match a boiler to the output of the system, after all it is simple physics, radiators cannot give out more then their designed output (i.e a 1 kw rad can not output 2 kw's of heat). A 600x1000 single convector rad outputs approx 1kw so a 30kw boiler could heat up 30 of these radiators (to help give you some perspective).

### Annex 6.E Determining seasonal boiler efficiency

2014-9-30·To convert from net efficiency to gross, multiply the net calorific value for the boiler efficiency by the conversion factor for the appropriate fuel, e.g. a LPG boiler 80% net efficiency x 0.921 = 73.68% gross efficiency.. The boiler efficiencies, measured at 100% load and at 30%, are used as the basis for calculating the seasonal boiler efficiency as described by equation 1 below.
