Hi all. New to the forum and I thought I would post a question.
I have a Potterton Performa 28. I have had it serviced by the same chap (Professional Plumber Gas safe Registered) every year and he is a friend as we are both gigging musicians.
As someone that builds power amps for the cinema industry I have electrical engineering knowledge/qualifications. There are cases when my friend has identified the problem and told me the part to get and I have obtained the part and fitted and he then pops around checks and I give him a fee for checking and ensuring done correct. Always simple issues over the last few years, anything tricky he does.
He is set to do a pressure flush on the system in October and at the same time a service. He is away abroad at the moment and not contactable... so whilst The Performa is switched only to the water setting the hot water tap even set to zero on the boiler will measure 60 degree plus and the water will be very hot... I was thinking it could be the High Limit Overheat Thermostat Stat 248079. The same problem occurs if switched to radiator and hot water setting.
Any thoughts? cheers
