Heat Loss Calculations

[RickH]

Would like to recalculate the Heating requirements to confirm correct sizing of a replacement boiler.
I know there are loads of ‘radiator sizing Apps’ , such as Stelrad or Castrads.
Anybody recommend a good one to use.

Anyone know of any free Apps to do this for whole house ?

Thnx ... I used Stelrad one a few times, but only for the odd room. I’ll go take a look.
