Can anybody help ? I have a 8 year old Vallient Turbomax boiler and have started to have problems with the hot water.
While using the taps and shower the water starts off coming out hot and then goes cold and stays cold. The boiler doesn't cutout but the only way to get it to go hot again is to turn the boiler off and on again. The water goes cold after about 2 minutes of use. I recently tried flushing the system, with chemicals, and it did stop going cold for about a day or so. I have not taken the chemicals out of the system yet, as they have only been in the system for about 3 days. I have ran the central heating 2 times to allow the systems to get hot. Yesterday the water started to go cold again. The difference this time is that the boiler use to cut out and show a F22 fault, but now the temperature just drops and the boiler stops coming on (flame light indicator not on).
Please can somebody help.
