Regarding the test that Tony mentioned, I ran the hot water for 10 minutes, with the radiators turned off and got the following results. The hot water temp at the boiler was 80 degrees C, after 2 minutes this had reduced to 46 degrees C and it remained at that temperature for the remainder of...

Thanks Tony, I will do as you suggest tomorrow, HANE and 73's, Dan

Thanks for the tips guys, I ran the hot water for 10 minutes and the radiators cooled by 2 or 3 degrees, when I turned the hot water off the radiators came back to their normal temperature in a couple of minutes. I will try the other suggestion tomorrow, turning the radiators off, letting them...

I have a Vaillant Ecomax 824/2 E, which was installed about 5 or 6 years ago but in the last few days there has been a problem with the hot water supply. The problem is that after I run my bath as normal I jump into the bath and find out the water is nearly cold, ouch. When I investigated I...

Thanks Bripl and Chris, I will try and fit that omega shaped linear expansion thingummy as soon as it gets warmer. I have plans to fit a new boiler and a couple of new radiators this summer and I can do that at the same time. I will fit the special expansion bend in an airing cupboard that the...

Thanks CH4, will try a couple of those and see how I get on. Best Regards and have a very Happy New Year.

It's a bit impractical to replace my 200 feet plus of copper tubing with plastic pipes but the proprietry expansion couplings sound interesting, I am using 3/4 inch diameter copper pipes, where can I find some proprietry expansion couplings ? Thanks....

I have rather a long house, about 90 feet and I'm having problems with the amount of expansion of the copper pipes in the central heating system when they get hot. The expansion has caused a couple of leaks, because as the pipes expanded they were stressing some of the joints. Is there some sort...
