Boiler sizing from heatloss calculations
Hi,
I've done the heatloss calculations on my house and came out with a figure of 8.4kW. What factor would I need to multiply this figure with to get the boiler size? I am assuming that I will need to allow 7kW for the DHW. Is there any disadvantages in oversizing a modern (modulating) condensing boiler (ignoring the slight difference in purchase costs). FYI: I plan to get a heatbank like the McDonald Thermflow. Cheers, W |
