Can anyone please help?
We have a Potterton Profile 60e. A new pump was fitted a couple of weeks ago as the old one was making an awful din. The heating was fine until the last few days.
Now, our heating has started to play up. The hot water works fine, but the radiators do not heat up properly. Those upstairs get warm, but the downstairs radiators remain cold. Eventually, they will all get tepid.
Things that I have tried:
- bleeding all radiators and pump
- turn all radiators off and then on again one by one
- ensuring room thermostat is on full and boiler is up to full
This got the radiators working last night, but this morning, only the hot water worked properly and the radiators were cold again.
This morning, I turned off the hot water, but left the heating on. Within a few minutes, the radiators heated up fully. I have just turned the heating back on and the radiators are staying hot.
The manual lever on the diverter valve, a Honeywell FS 9824, flops about and does not seem to work, although it did move when I turned the heating back on again.
Does this all point to a defective diverter or am I missing something obvious elsewhere? Any help would be appreciated.
Thank you.
James.
