Hey guys,
I've recently moved into a coach house (all on one floor), and we immediately are having trouble with the central heating. Some of the radiators were heating up well and proper, but others weren't. I switched off the ones that were heating up, and the others did indeed heat up.
We've only been in a few days, and the boiler is knocking shortly after lighting up. A video is uplolading, i'll post soon...
Now to my very basic knowledge, this seems to point towards low pressure in the system? I am trying, but can't for the life of me find a pressure gauge. I've taken the front off the boiler, been up in the loft etc, all around the tank - but can't find one. Nor can i seem to find a loop to re-pressurise the system. Under the sink is a large mix up of wires and tubes from the washing machine, i havn't yet decoded these.
The other issue i have is that the central heating (havn't set the water to heat up yet) seems to also be heating up the water. I set the tank thermostat at 50C and the water is getting well above that. The motorised valve (3 way - Danfoss) doesn't seem to have any "spring" in it. When i moved in, it was set at manual. I can switch it to auto, but there is nothing to pull it in that direction... It also seems to be fitted upside down, on the side of the unit it points down "A - Heating" and up "B - Hot Water". On the piping it's fitted to, A is up into the ceiling, and B is down, into the tank.
The only other thing is that there is a pipe going up, with a white knurled knob on the end. When i undo this, i can read a gauge of bar readings, 0.6,0.5,0.4 etc. What is this for?
Any thoughts on helping us?
Cheers, Patrick
