Thanks or the reply, 3port valve is definitely not reversed. Just had both DHW and CH on calling for heat - boiler running beautifully. If i switch off the DHW demand the boiler switches off as soon as the 3port does it's stuff and whilst on this occasion the boiler did relight some minutes...

Thanks for the reply, boiler thermostat is set to 80 degrees which is the temp which the boiler will run to when it's heating the hot water circuit. We do have some rad valves on TRV's but there are plenty that are non TRV and open. All radiators have been bled and all radiators warm evenly...

Hi guys, from reading the forums seems like lots of people having C/H problems this Xmas - here's mine: During summer had a number of problems with the boiler had it serviced, 3 port valve and pump changed and everything seemed fine. However problems have started to resurface, the main one is...

Actually I thought your misquote was pretty scummy and I'm ashamed I've lowered myself to your level :cry: 7.5k plus posts? let's hope some of them are better than what you've managed on this thread otherwise I'm on the wrong forum. Was just trying to help the original poster - personally...

Blown your dole money already? never mind.

Yeah, it will crack, you could use castable refractory. Google "pyromasse" - it's a site about masonry heaters but the construction methods would apply to what you are trying to do.

But it you do that Nige you just get a long dingy corridor with no light. I’ve had a quick play around, I’ve made a number of assumptions: That you don’t have loads of money (coz you would simply buy a bigger house). You won’t be moving out whilst the work is completed. You have limited DIY...

Hi Woody, thanks for taking the time to reply. I appreciate that a true triangulated truss does work diifferently in terms of load sharing but the attic truss is more framing than true truss. I'm not an engineer (obviously) but I cant see what forces are acting on the centre section of that...

Hi all, was just looking at some attic trusses and now I'm confused (although in fairness it doesn't take much to confuse me!). The truss in question is 47 x 220 mm, approx 8m wide. the distance between the vertical ends on the bottom chord is 4.8m, how is this possible when according to the...
