What happens when you say you have tried to pump it up?. Is it leaking through the pressure relief valve?.

What pressure have you topped it up to

Which model is it

 

[strangelad]

When you say you tried to top up, do you mean you stuck the key in the valve and turned it on? I'm only guessing as I used to have a Vaillant that topped up like that.

Sorry to hear that, Phone your insurance company right away.
Also turn of your boiler and cold stop tap and open all taps in case other pipes are frozen

Thanks Spraggo, I have turned off the boiler, and hopefully be able to get repaired tomorrow. copper pipe going into a plastic Tee must frozen and popped out of Tee. Looks like no damage to copper pipe so am hoping to repair tomorrow. Ceiling is looking a bit wet at moment, hoping it will dry out, got the dehumiders & Oil filled radiators in the lounge hoping to dry it out.

As the burst is in the roof void, , and there are only 3 radiators on that level I am right in assuming that only the water out of those radiators will have escaped, and not out of the whole system? IE the 6 raditors on the ground floor??

WHen I caome to refille the system, can I just top it up or will I have to drain to all first and then refill??

It should be a matter of repairing the leak and topping up plus bleeding the radiators above the leak.

Thank you spraggo. Thats what I was hoping for.

Have hopefully done the repair today, and will be refilling tomorrow. Problem was only had a small confirned space to work in so took a bit of doing. (Dormer bungalow, and pipe was in roof void.)

Had oil fiiled radiators on and dehumidifiers, and the lounge ceiling is not looking too bad at the moment, no bowing of the boards. (Fingers crossed)

Thanks once again.

If it is an ecoTec check the filling procedure.
