Can anyone please tell me what a type K thermocouple wire with plug is for a multimeter? Is it a connection that tests the working of a thermocouple? Or can it be used to test the resistance of wet pocket thermistors/certain thermistors? Thanks for any help.

How do you spot / test for a faulty resistor or transformer on a boiler PCB?

I have been reading posts and understand that a scaled or sludged up heat exchanger can cause poor heat output from the radiators in general due to the water in the boiler not getting hot enough, due to the scale/sludge. How is this so? Surely if anything it would make the water going...

Can a 3 port valve stick in the HTG only position? And if so, will it bring on the heating (by firing boiler/starting pump) constantly or ONLY when the programmer gives it power via the stat? I know 2 port valves can stick and override the prorammer and room/cylinder stat as they have a...
