Central heating boilers/radiators

Get a bucket and a spanner on one of the pipes going into that rad and drain it or it is very likely to pop and cause a huge mess. Check any rads near your doors as they may have a drain valve on one end that you can attach a hose to and just run the water outside.

At the very least open the bleed valve and let the pressure out.

New rads are fairly cheap and the newer design are a bit more efficient as they hold less water. Did they not fit Thermostatic Radiator Valves to all of your rads? If so I'm pretty sure that means your boiler install doesn't meet the building regs. Did you get a CORGI certificate for the install?

Right, turns out the guy that came earlier on today thought that the system was losing pressure so he turned one of the valves underneath the boiler to increase the pressure in the system.

Well,he didn't turn the valve back and left it like that, hence the water dripping from a pipe outside , and the needle showing the pressure was as far as it could go (past the red) - wasn't aware of this, was my mum that was here this afternoon.

And only since he opened that valve the radiator started bulging ! Can't believe what a hassle getting a new boiler has become !
 
You're very lucky, that radiators could have quite easily have gone pop, as could all of the pipes and the boiler itself. New radiators can be had for <£50 so get him to replace it and double check all of the pipes to make sure none were damaged with the excess pressure.
 
They said they will call us tomorrow with a quote for everything (they said to replace all the radiators)

Surely we shouldn't have to pay for this radiator and installation if it was his fault in the first place :eek:
 
i can't beleive you didn't try and bleed the pressure from the system using a bleed key. hmm no wonder it was bulging if the valve was left open though - it'd just be seeing mains water pressure. ace.

you shouldn't *need* all new rads (just replacing the blown one). newer rads will be more efficent at kicking the heat out than the old ones though.
 
Consider yourself very lucky, the rad could have blown as could have some fittings. Very irresponsible of the guy to leave it on and forget to turn it off. He should be replacing that rad from his own cost because it is his own fault that happened. You don't really need new rads but if you got the money I'd get it done, they are much more efficient and will heat your house up much quicker.

They should have told you what kind of pressure to leave the system at and how to drain it if the pressure gets too high or how to fill it if it gets low.

We haven't been told any of that.

Yeah, will probably still be worthwhile to get the radiators replaced - but will make sure not to pay for the one he has broken due to his own fault.

At least the thing didn't blow, then it would probably get more expensive for him
