We have one old style radiator that's just not releasing all its heat.
The return pipe is just as hot as the supply pipe. So, not that it's
such a great idea from the cost perspective, but would it help to have
a fan blowing air onto the radiator?
Maybe try it, Is it HW is it bled of air, or steam, if one pipe steam
