    Hot taps don't flow until cold is turned on and off

    I'm not aware of any pump. To be sure, I turned off my whole house electric at the main consumer unit, and was still able to draw hot and cold water.

    Hot taps don't flow until cold is turned on and off

    In my house, if I turn on the hot tap, no water comes. If I leave the hot tap on, and then quickly turn the cold tap on and off, I hear a "thump" from the pipes and the hot tap starts flowing. This normally fixes it for a few hours, and then the issue comes back. This issue happens at many of...

    How does my boiler know when to fire?

    I have an Ideal Classic FF boiler. When I request hot water for taps or radiators it should fire. I'm trying to work out how it knows to do this. Referring to the documentation and inspecting the boiler, it looks like it has just three external connections: Mains power in. Water in. Water out...

    Troubleshoot Honeywell T6360 thermostat

    I have a Honeywell T6360 thermostat that I suspect is failing and would like to confirm that before I replace it. (Symptom: radiators not turning on). Looking at the wiring diagram, would I be correct in thinking if I short pins 1 and 3 it would simulate the effect of the temperature being high...

    Sometimes have to turn my thermostat down and up for the heating to come on

    I have a Honeywell T6360 thermostat and ST6450 digital programmer. Sometimes I notice that the radiators and house are cold. I go and check the HEATING red LED on the ST6450 programmer and it is lit, indicating that the radiators and house should be warm. I then check the thermostat and if I...
