I had my loft convertoed just over a year ago and have 2 heat sources up th ere. A towel rail in the bathroom and a 2m x 30cm rad under the large windo w.
I'm in a 1930 large semi and have a Ecotec Exclusive 832 32kw combi.
I initially fitted the heating and used 10mm copper tubing, which has worke d fine over the years.
When we had the loft converted, getting services up there was tricky and th e plumber recommended putting a "T" from the landing heating tubes that fee d the 1st floor small bedroom. He said that flow would not be an issue - wr ong !!! (I relied on his superior experienced knowledge and yes he was clue less, but that's another story)
The rads in the loft dont get hot, but just warm. Despite numerous attempts at balancing, I cant get them red hot, like in the rest of the house.
I'm now considering radical solutions, like a dedicated boiler up in the lo ft, which wouldn't actually be that difficult to fit, though I'me told I'd need to ramp up my gas supply (at a cost?) - I'm wating for a call back on that from the supplier.
Can anyone offer any advice here - would pump speed make any difference ? I was looking at the Vailent setttings yesterday, and the pump is set to 60% .
Alterrnatively, I'll have to bite the bullet and look at getting a dedicate d flow and return to the loft, which would be very invasive :(
Thanks in advance for any tips.
