Hi, I have a problem with my hot water system...
I have just replaced a hot water cylinder (and emersion heater) and also fitted a new hw pump as the old one was worn out. When I switched the system back on I noticed that the pump and boiler were running even though the programmer was set to off?? Have since replaced the cylinder thermostat and programmer still the same problem.
The boiler switches off once the thermostat on the cylinder reaches the set temperature but doesn't seem to be controlled by the programmer??!!
I have an oil fired boiler and wondered if this might have a fault which is overriding the programmer...is this a possibility or likely??
Any suggestions gratefully received...
