Hi all,
I have a problem with my CH/HW/Boiler and I need advice
Last year I had two rads excanged (re-decorating and went for towel rads). Shortly after, the following problems started happening and I'm waiting for the same guy to come back for other work so he can sort it out (I know what you're going to say!).
I wanted advice before I speak to him/see whether I can do something myself.
1) The boiler starts kettling, well more of a bubbling/gurgling sound after about 20 minutes of being on/or immediately if the water is already hot.
2) The rads/pipes and pump seem to get very hot and I can hear whooping and high pitched screeching noises where the tank is.
3) I dash down and turn HW/CH off at the thermostat and the pipes shudder and shake and it sounds as if there is grit/sand being poured down them.
The system wasn't drained when the new rads where put and there is definately air in there. One of the rads needs bleeding constantly.
The boiler is a GloWorm Ultimate 40 BF and the pump is a Grundfos 15-60 (its upside down) on a gravity fed system. The pilot light wouldn't come on the boiler recently so a Corgi guy replaced the valve and that worked. I think the house is 8-10 years old. This is the first problem with the system and it only started after the new rads were put in.
I've read other posts and gathered it could be air, faulty pump, or the header tank (what am I looking for here?). But thought I'd give you my exact scenario in case you've seen it before.
Any help gratefully appreciated...Thanks guys
David
