Hav got a Vaillant EcoTec Pro 24 combi boiler.
Hot water is working fine, so can take a bath, use hot water in sinks etc
But I tried to put the central heating on recently & the radiators didn't heat up when so turned the valve to 3 or 4.
Boiler pressure seems ok at around 1.5 & getting no error messages.
Have changed batteries in the thermostat.
I've reset the boiler a few times but not done anything.
Original boiler installed just over 1
0yrs ago.
Also the timer on the boiler doesn't work anymore. Is a mechanical analogue timer.
Can I replace it with a digital one?
And what is life of a combi boiler? Don't want to spend money replacing parts if better to replace boiler.
I've got some photos of boiler & thermostat I can attach.
