Why does my hot water only work when heating is on?
It is common for a faulty diverter valve to only become apparent in the warmer months once the central heating is not needed. If hot water only comes out of your taps when the central heating turns on, it is likely that the diverter valve is not diverting hot water properly.
Are there any problems with the Potterton profile boiler?
A relatively common issue with older Potterton boiler models such as the Potterton Promax, Suprima and Profile models is an issue where the heating works but there is no hot water. A similar, but slightly less common problem is the other way round with hot water working but no central heating.
Is the combi boiler used in the UK?
Most UK homes rely on a gas combi boiler for both heating and hot water. As well as being effective and economical, they also have a reputation for being extremely reliable.

How does a diverter valve in a combi boiler work?

What should I do if my Potterton boiler is leaking?
This is sometimes a minor job that you can do yourself by tightening a joint or using a DIY sealant. If the issue is with a soldered joint, it is usually a relatively minor issue to fix it. Once you have identified and fixed the leak, you will then be able to repressurise the system and it should now work as normal.

Why is the central heating not working on my Potterton?
If they are and there is still no activity from the boiler then its likely the PCB. I rather suspect that this might be due to a sticking diverter valve – I have had this problem with a Potterton Combi 100. It seems you can only purchase the entire valve assembly at around £80 though I think it is usually just the wax thermostat that packs in.
