Advice on heating in a new build property

slacky · Dec 14, 2019

Hey guys

looking for abit of advice on my heating system in a house I’ve just moved into. Last week I had to bleed a few radiators which I thought was normal but today I’ve had to go round bleeding them again and there was quite abit of air in them. How often should they need to be bleed? The down stairs toilet needed bleeding first time round but now it’s stone cold but doesnt need bleeding. What could be wrong with this? Also a few radiators are hot to touch but if I put my hand over the top it doesn’t feel like much heats coming off them and lastly for a new build property it’s costing anything from £4-6a day for gas and the heatings only on a few hours a day but doesn’t seem to reach temperature. For a new build property it seems abit excessive my old house was built In 1960ish and didn’t cost this much to run.

any help would be appreciated

thanks

I took one but unsure if I did it right. Does it matter if it’s in the dark?

Nothing remarkable on this image or the others, you have a fairly well-insulated house.

Set the pump to 3 pretty much the same. What I have noticed is when the boiler and hot water are on at the same time the temperature on the front of the boiler was 65 and most rads in the house was warm not hot but when the hot waters off the temp goes back to 80 causing the rads to get a lot hotter. Is this right ?

ive also purchased a thermal imaging camera to get for any Heatloss but my experience with this is next to nothing. Can any one shed any light on these images ?

On an earlier post you said you had turned the stat on the front of the boiler from max to the eco setting. Is this still the case. You now say boiler goes to 80 with just heating on and 65 with both on. You sure you’ve not got weather compensation fitted the only thing being the temps should be the other way round if you have. Boiler would default to 80 when hw demand but vary when no hw demand
