Hi all,
Thanks for taking the time to read this post,
My wife and I recently bought a house, and the guy who sold it claimed to have had the boiler serviced for cash so no certificate (have since found service stickers on the fire. Baxi Bermuda boiler, gravity fed system from the loft...). With that in mind I insisted that he turn all the rads on and the water before we signed, and everything was hot even though it was the middle of summer so happy days I thought...
Have now come to start using the heating and the two downstairs rads are stone cold, whereas upstairs get nice and hot.
I have set the thermostat to max of 30 degrees, and the Grundfos pump is also running at max speed. It has a mid way valve just above it (WMH valve?)
I have bled all the radiators and the valve in the airing cupboard by the hot water tank (no air in any of them) and taken off the inspection cap on the pump, which then let out a steady stream of very hot water, and the spindle was moving when I put in a screw driver to check.
There are rads to the right and left of the hot water tank upstairs, which both get nice and hot. The two further out to right (bathroom, slightly rusted) and left respectively both get pretty warm, and the two downstairs to left and right are both cold.
I have followed instructions to balance and this hasn't made a difference downstairs, but has made it slightly more even upstairs in terms of heat distribution across the 4 radiators.
Last night I turned off all 4 upstairs rads, and the one downstairs (left) in the lounge then got very hot, but the one in the kitchen (right) was still stone cold. The one in the kitchen does not have a bleed valve at the top, only a valve at the bottom right. I opened this up, and attached a hose pipe and drained off the cold water into the sink until it ran hot, which caused the kitchen radiator warm up, but only because hot water was passing through it and out of the hose pipe. I read that doing this until you get hot water could clear an airlock in the pipework.
I also noticed that in the evening when the heating is on for about 4 - 5 hours is cuts out after about 3 - 3.5 hours, even though the temperature is nowhere near 30 (it's around 21 degrees).
I then opened up the radiators upstairs for this morning, and they got hot again as usual, and the ones downstairs were stone cold again.
Any insight into how I could potentially fix this would be much appreciated. If that doesn't work, then a recommendation for a good plumber in the Aberystwyth area would also be great, but as I'm a bit tight for cash right now that's a last resort...
Since we moved into the house in August the gas was turned off to fit a new cooker, and I didn't think to relight the pilot light on the boiler for about a month. I only realised when the electric shower cut out in September, and then spent a whole evening wondering why the pump etc was running but we had no hot water. Could this have sucked air in?
I'm just so confused because the system was running when we looked round the week before exchanging contracts and moving in!
Thanks so much for your time guys,
Richard
