Hey Guys,

Wife and I recently bought a new house which needs a bunch of working doing it, its very likely going to be our 'forever house' so im spending the time and money making everything right.

However, over the past few weeks i've been suprised at how quickly it loses heat and how slowly it warms back up. This is my first detached house (timber framed), so perhaps this comes with the territory in the winter months but i'd be suprised if this is normal. A couple of points:

1) The old wooden framed windows are slightly rotten, so they are being replaced with new UPVc ones.
2) Front an back wood door is also badly fitting, visible daylight can be seen in multiple places. Also being replaced with composite doors.

I also had BG come out to service the boiler last week. It was serviced shortly before we purchased it, but i noticed not all of the radiators get piping hot, some only get warm (i have bled them). BG mentioned the heater matrix is on the way out and the boiler will be continutally overheating and thus shutting itself off regulalrly, i havent noticed it shutting itself off though.

Im hoping the new windows and doors will help retain the heat, although getting a second opinion on the boiler is probably sensible.

Has anyone else had issues with thier boiler 'overheating' and leading to a lack of radiator heat?

First suggestion is get a decent indie heating engineer to check, I wouldn't believe BG if they told me the sky was blue

You'd know about it overheating as you'd be forever resetting it/have it cutting out on you.

You may just need to balance the radiators or clean the system one way or another.... Prob best to call out someone else, whatever you do don't just go chucking chemical cleaner in unless you know what you're doing as it can cause the crap to move and block up elsewhere.

Do you know old the system is? If it’s old you may have what is known as a “one-pipe system” where the water flows into one radiator and then out and onto the next. This means the water gets progressively colder the further away you get from the boiler & the rads at the end of the line are noticeably colder.

My system is like this and some of the rads are not very warm at all.

A flow and return system has hot water flowing into each rad and separate pipework taking the water away & the rads are much hotter.

You may realise this, but only some of the water goes into the radiator - the pipe runs straight past it, with the radiator teed into the pipe at both ends.

They can work OK - our (1967) house was done like that - but I changed it anyway some years ago as all the ground floor pipework was buried in the floor.

Yes indeed thanks for pointing out. Otherwise turning off one rad turns all the others off down stream!

System pressure correct @ 1.5-2 BAR? Circulation pump set to medium-high?
