Hi I have a Potterton Gold combi, about 15 yrs old, and a thermostatic shower. When the shower is run, the boiler doesn't always ignite or if it does, it cuts out after 30-45 secs. I don't have this issue if i run a bath. In fact, i notice that if the shower runs cold and i switch on the HW...

Great, thank you. Link fitted, boiler working. Also now know what the fault is! Cheers

IS it possible to bypass thermostat on this boiler? Just desperate for some heating in the flat! Thanks

Danfoss TP5. The flat has just been re-wired. Possible that the hard wire to thermostat has been cut / damaged?! Unfortunately I don’t have anything to test if mains supply reaching the thermostat.

Hi My Vaillant Turbomax Plus provides HW when tap turned on, but does not provide CH when external control demands. The status on display reads S.30 which is ‘no heating demand’ despite thermostat showing demand. The heating did come on for about 30mins, then switched itself off. I’ve heard...

Thanks for responses. I'd never heard of acquapanels before! Also found the link to Historic England given on a related thread v useful. Cheers

Hi I'm renovating my bathroom and I'm interested in insulating two exteriors walls. The house was built 1920s and currently the walls are plaster & lath. The bathroom is on the first floor. The bathroom is quite small and I'd rather keep the loss of internal space to a minimum. I'm thinking...

Hi My thermostatic shower has stopped working. It produces a spray of water for about 10 secs then the flow reduces to a trickle after about 20 secs. When switched on, the boiler initially fires up but then cuts out when the flow slows down. HW taps to bath and basin work fine and there's...

Hi I removed expansion vessel, and drained it. Really dumb question, but is it possible to inflate a disconnected vessel? When I try air just escapes. Is this because it's disconnected, or should it still inflate to desired pressure. I read elsewhere that when you have a problem with a...

Hi Thanks for advice above- much appreciated. I disconnected PRV pipe and note that when CH switched on, pressure increases to 3.2 bar and then there's a steady discharge of mucky water. When the system cools down the pressure drops to below 0.5! I feel as if I'm making progress now...

Yip, I think the fan is a separate issue too. There was also an error code showing the was a fault "water pressure switch not operated" but this seems to have been overtaken now with the fan alert. The loss of pressure: is that likely to be connected to a fault in the expansion vessel? Or...

Hi I have a Potterton Gold 24he combi that keeps losing pressure, needing refilled every 24 hrs. Error code points to an issue with the fan, but i think there has to be another fault to account for the lost pressure? When the flow and return pipes are switched off at the boiler, and left...
