Hi all,
Hot water only lasts 2 - 3 minutes, if I turn it off for a minute hot water returns for a couple more minutes. It seems to last longer on a lower pressure. We had a plumber change the heat exchanger which didn’t make a difference. And it’s not the thermal mixer in the shower as we had that changed too. It happens on all hot taps but really only affects us in the shower. The boiler is a 17 year old Valliant Ecomax combi so I’m thinking that it’s probably just time to replace the boiler but would rather not spend that sort of dosh if there is an easy fix. I have also flushed the system twice with sentinel cleaner which might have made a small difference. But our radiators are hot so I’m confused why replacing the heat exchanger didn’t make a difference. As a side note there have been a few days where the ignition flame didn’t come on automatically and we needed to press button to ignite but I wonder it that might be linked in any way.
thanks in advance for any advice.
