Hi,
I've just moved in and have been experiencing some problems with my heating and hot water. I have been here a week now, and now have no HW or CH!
When we moved in last Thursday, we noticed that the pump was pretty noisy; this appeared to be caused by a lot of air in the system judging by the bubbling noises. I did not bleed anything at this time.
Last Saturday, I removed two downstairs radiators in order to decorate. Upon re-fitting and bleeding, they did not bleed until water appeared; just bled a small amount and then stopped. These two radiators did not get hot when the heating came on. The upstairs rads seemed to be working fine, however I later noticed that none of the downstairs rads were working.
The pump remained noisy, only now it seemed that other radiators which previously worked upstairs were not working. These also failed to bleed properly. These rads then started working intermittently.
Attempting to bleed the CH or HW circuits at the bleed points next to the HW cylinder results in the same unsuccessful bleeding, with air obviously still present but no pressure to dislodge it.
This morning, everything is cold. The Boiler still fires and heats the pipes next to it, but then cuts out (probably because the water isn't circulating to it's reached its temperature threshold). I have no HW and no CH! Pump still operating (but now quiet so no bubbles passing through). The 3-way valve seems to operate normally.
I decided to try draining down the entire system, however this seems to be fairly unsuccessful too. Even with the cold water feed from the header tank open, and a hose running outside, water will not flow from the tank into the system.
Any ideas, please?! I'm considering connecting the water feed from the header tank to the mains to flush the system through.
Cheers
Richard
