I've been asked to investigate pressure loss in a heating system.
Pressure relief valve is ok.
Expansion vessel is OK.
Boiler heat exchanger is OK, plus it's a new boiler anyway.
Cannot see leaks under the floors. But there is one screed floor with one radiator. The pipes are copper in a...
What ever boiler we choose, it's bound to be so environmentally friendly and so efficient that land fill receives 5 boilers in the life time an 'inefficient' boiler lasted.
Hello, have a potterton Promax 30sl, 6 years old and the heat exchanger is leaking.
The new boiler, should I avoid potterton altogether? Any good ones to recommend when I get an engineer out?
Thanks.
I've usually always used that grey foam pipe insulation to insulated heating pipes, but I've been thinking, for domestic work, is it really worth (for the customers gas bill) going for that cooltherm kingspan foil lined pipe insulation that I see on commercial jobs?
Thanks.
Good morning, I've just been asked that if someone has a tap which shuts of the water abruptly, such as the cartridge valve taps and water hammer occurs, would fitting a small expansion vessel close to the tap relieve this? To be honest I have no idea but I can find the logic to this question...
I see what you mean, but there are laws about gas and unvented cylinders for safety reasons due to explosions ect. Then again I've known DIYers who've bashed out much better jobs than people I've worked with!
Evening chaps.
I've got a Bristan monobloc mixer to fit. Now, the 10mm ends of the hoses fit a few inches deep inside the body of the tap, so can't get a spanner on them. Can't use a box spanner as even if I could get one on the hose, I wouldn't get it off as the other end is 1/2" bsp!
What do...
Ok chaps.
What I've done is used 25mm flexi conduit to sleeve the copper, to protect it. No insulation on it as it's above celotex boards, so it's in the warm part, just to be covered with screed.
