Not sure what's going on.
I have an oil fired system boiler - Warmflow.
I noticed this morning it seemed a little noisy - the boiler was hot and the pump was running.
I turned off the CH and HW at the timer - the pump still continued to run. I guess this is normal to prevent the boiler overheating (?).
More strangely, the boiler then fired up even though the ch and hw were switched to OFF on the timer. How can something be calling for hot water when these are off at the timer?
It also fired when I turned the thermostat on the boiler up, even though the ch and hw are turned off at the timer. How can this be?
Any advice please?
