microswitch

My boiler struggled to circulate throughout my house so my heating engineer installed an auxilliary pump a few years ago. On a recent service he identified that the auxilliary pump was not working. He said that it was down to the motorised valve and he wants to charge £350 to replace it. He said...

Hi. Currently experiencing an issue with our oil fired central heating system. When CH/HW is switched on, the central heating does not always work - the hot water does however without fail. We had the timer set to come on last night but alas, only the H/W came on. After a couple of hours of...

My boiler isnt giving out any hot water I can see that the the little plunger that closes the microswitch isnt moving so i can assume that the diaphragm needs replacing? The problem i have is if i close the microswitch myself which then turns the hot water light on the display and flames...

Hello all, our Baxi 80 eco boiler has started firing up the CH whenever it's switched on, no matter what the timer, integral thermostat and room thermostat are set to, and even if the function knob is set to HW only. Had a guy come to look at it, and he said "it's probably the frost stat" but...
