Yes that sounds about right. Heating will be on 22mm pipework, branching off to 15mm for each rad/ a leg with only two radiators.

Hi All, Just in the process of starting to piece back together my house and i think I know the answer but would like to have it confirmed if anyone can help? It comes down to pipe sizes that I will choose for replumbing... For background info: - it's a 3 bedroom house, with a basement, one...

hehe thanks, I had a play, i was surpised at just how much of an effect on kw output it has, when you adjust the flow temperatures! very low flow temps would need some very enormous rads!

Thanks again John, after reading it several times, that makes sense now :)

Right you are, I thought they'd calculated it at t40 but I ahve re-read what it spits out: "Your room has the following heat output requirements: Watts = 331 BTU = 1129 You will need to purchase radiator/s where the T40 (Δ40) is greater than the amount shown above." so i'll divide those values...

Hi John, So that’s what the radiator calculator form quote. Which happens to be in line with my aims: 65c flow temp, 55c return, 20c room temperature. I’m just getting to grips with the delta stuff so forgive me if that isn’t right..

Hi all, I'm a long time lurker, first time poster.... I'm in the process of finally putting some plumbing back in my house after surviving with just a woodburner for some time! I'm fairly confident the central heating layout would work but would welcome input from anyone who can see any issues...
