Has anybody got any idea as to the best way to calculate the above.
The hall double panel 19" x 24" with one fin laye rradiatr does not have a temperature valve fitted, the landing, a singfle panel the smae size does. The hall and stairway feels as if it needs more heat, i.e. a biggerhall...
I have a steel double panel radiator with single fins, size 19" x 24" app 25 years old and want to replace it.
I need to know what the BTU of this radiator is before I can replace it with one with more BTU.
Can anybody advise please?
Thanks.
