Only kinked when it let go, it was straight before it exploded.

Unless someone knows a good heating engineer in Suffolk who can work on unvented systems? I switched the heating on last night, 2 towel rails, 3 rads (one bleed?)and one room UFH served by an oil fired Rayburn, it hasn't been run since the winter, after a while I heard a loud wooshing and the...

Anyone know if these guys are still around? Their number seems to have changed and I cant seem to find a current contact number. We have a fairly complicated looking installation from 2006 and it needs some work and I figured the best people for the job would be the same people who installed it...

Don't fit a tap with an anti return valve built in, they are less than useless.

Will do, Ive switched on the central heating, stat switched to 30, hot water off. So the stat was calling for heat but the boiler didn't fire up. I manually activated the motorised valve via the little paddle lever on the side, it clicked and wirred then the boiler fired up. So I take it the...

So the motorised valve isn't working either? If I try to heat water my rads also get hot thus expanding the water to 3.5 bar?

Ive found out why its pressurizing, I think. I tried to heat some water, its an indirect system as far as I can see, I may be wrong, the boiler heats up a copper cylinder, it also has an electric immersion as well. Anyhow, ran the boiler to heat water and the system is reading 3.5 bar again. So...

Fella down then road from me fitted an electric combi boiler, he reckons its great.

Ok, thanks Tony, I only have a bike pump, so its looking like I'll give the land lord a call and hand it over to him to get sorted, thanks again.

Ok, so I looked at the bottom of the vessel, dipped the pin in the air valve and nothing happened, no air came out nor did any water. So I released the pressure in the system then tried a pump on the vessel, it wouldn't let any air in, is this a sign that its full of water or just that the valve...

That's what I was thinking Tony, I cant see why the pressure would rise like that in a cold system. Ill release any pressure and pump up the expansion vessel, would it be prudent to release any air pressure in the vessel first? I take it the 1 bar will be read from the pressure gauge ontop of...

Its an oil boiler, heating and hot water, hot water is via a copper cylinder in the hot press, it has an external expansion vessel. You know when you fill a central heating system via the service valve? Between this valve and the boiler is an expansion vessel. I was always under the impression...
