Hi.
How do I work out what size boiler to get? We are installing underfloor heating throughout our 5 bedroom house. Is there a tool to calculate what size I should be looking at?
Thanks

you need to calculate the heat loss from the house then add on for hot water requirements (usually 3kW)How do I work out what size boiler to get? We are installing underfloor heating throughout our 5 bedroom house. Is there a tool to calculate what size I should be looking at?

quick and dirty
Single or two storey?
What thickness slab?
Square meterage where pipes have been laid.
In very general terms a boiler that is too big will short cycle leading to loss of efficiency.
I work on 50 watts a square metre for sizing purposes, but this is NZ and I only install air sourced heat pumps.
