Its a very large house i thought about banking a couple of 24ri s but thatll be well over and the customer whats the boiler to go back in the same place.
Ive just replaced all the rads as they were original from the early 70s the boiler thats currently in there a suprima 100 is kicking out 29.97kw but only giving a flow temp of 60 degs on full chat after an hour or so.

Needs to be wall hung if possible

by replacing old rads with new you have probably upped their output considerably now that modern rads are finned and very efficient, you need to work out the total output of all the rads you have installed then see what size boiler(s) you need or you may just end up with the same problem again. bank up a couple of intergas 24s maybe on a llh to ensure they work properly.

The customer was warned that this would be an issue at quoting stage as I did the heat calcs and sized the rads so I need 37kw Inc the cylinder as per my orignal post if I have to put 2 boilers in I'll have to roll with the ri don't like the sound intergas never herd of them.

WB do the 40 cdi it's got a bit of a price tag though will have to go with that.

Calculate size of boiler using whole house heat loss method.

Remeha Quinta, Worcester GB162, Veismann 200 series, Vailant ECOtec 46 or 65. Loads to choose from.
