Hello all
I want to replace 5 of the 10 radiators in the house with more efficient modern ones. The five are at least 25 years old (as that’s how long we have been in the house).
Can I just go for a similar physical size of type 21 or 22?
I know, I will probably have to adjust the pipework and am OK with that.
I read things about old designs being designed for higher flow temps and nowadays it is lower. Do I have to consider BTU calculations for each room?
Boiler is a 30KW condensing Vaillant and the house is a Victorian terrace (three bed + loft room).
