Hi,
I did a search of the forum and I couldn't see anything that I hadn't tried already. Apologies if I've missed something.
Our central heating boiler is an Ariston Microgenus. I couldn't see a model number on the documentation we have, however it looks identical to these so I therefore assume it is an Ariston Microgenus HE Condensing Combi boiler.
The radiators had been making a lot of noise and the upstairs radiators were cold at the top, and hot at the bottom. This has been the case for quite a while. I decided that this was probably because the radiators had a lot of air in them and need to be bled. The radiators were working, just very inefficiently.
Also, the pressure gauge on the boiler had way below 1 bar so I decided it needed to have more water added to the system.
In the process of tinkering trying to figure out how to add water to the boiler I tried loosening various little screw-head type valves (?) attached to the water pipes coming in and out of the boiler, thinking that one of these might enable me to top-up the boiler. I wasn't able to turn any of these more than about a quarter turn, so I don't know if that would have done any damage...
Eventually I saw this article and realised that I had to do something with the filling loop. I was finally able to top the boiler up a bit.
I then went around the house bleeding radiators. Only those on the top floor needed bleeding. The others turned out to contain only water. I was unable to bleed one top-floor radiator as it is in a locked room.
I then topped up the boiler a little more so that it was a 1.5 bar when cold.
Then switched on the boiler, set it to constant heating. It does heat up water, and sounds as if something is happening, but the radiators stay cold.
I switched off and unplugged the boiler at the mains, opened it and tried turning the screw in the centre of the pump, thinking perhaps that needed bleeding as well. Only a little water came out though, so I tightened the screw again.
So I'm left with a boiler that heats water, supplies hot water to taps fine, but apparently does not seem to be able to get the hot water to the radiators.
Any suggestions?
Yours freezingly...
