All of my radiators appear to be undersized in terms of BTU, Do I need to change all of the radiators???

hi

if all the rooms are cold with them full on then yes. if the rooms are ok the rads are ok

hi
ducati is quite right
but if this becomes an obsession you can do some research on the net regards radiater sizing or go to a supplier of central heating supplies and you can purchase some form of "matrix"device to work out the correct size

In fact this site in the projects section has a link to a radiator calculator.

What you need to be careful of is not to unbalance a system by fitting larger rads in some rooms and not others. If you do, some rooms may become very warm whilst others are cold.
