What size boilers?

[allwright]

Got 2 fualsavers 50B that needs changing. Each boiler has its own circuit, one doing 14rads and the other doing 12 rads. Both systems are all over the place so customer just wants boilers replacing. I'm thinking 2 x 18kw boilers. Any advice would be apreciated

Whole house size it and go from there or measure rads and get a idea of what outputs there using

100kW.....err :44:

But back in reality, calculate heat loss for house, then the load split between the two boilers and go from there

Work out the output from the rads and check they are sized correctly for the room. Ask the customer about any plans for extensions in the future etc and then size accordingly.
