Having a ground floor extension built to create an open plan kitchen dinner. In passing conversation with the builder he said that his plumber would want to replace my current 7 year old Glowworm 15r heat only boiler! Have not had any conversation yet as to why he feels this would be necessary.
During the build, 2 radiators will be removed and replaced with wet UFH in the rooms.
I'd like to hope that the plumber could provide good reason for his suggested boiler change but just so that I am in a position to challenge him could anyone recommend a resource where I could do my own calculations for the boiler size required?
Thanks
