  • thanks for your help guys

    basically you established that i'm clueless with this kind of stuff.

    the issue was that the boiler and thermostat are located in the kitchen, basically right next to each other. when the walls were replastered i didn't want the old thermostat going back on the wall (it's really manky and the wire is held together with all kinds of electrical tape) so the plasterer/carpenter guy i had working for me said it wasn't entirely necessary to have a thermostat on the wall next to the boiler, you could just disconnect it and set the temperature on the boiler directly.

    so he disconnected it and threw it in the bin. i thought the boiler would then work when i either set the timer or just turned it on, and the temperature would be set on the boiler itself.

    so how wrong were we?

  • Are you hoping to run without a thermostat on a permanent basis? If so you need to find out how to jumper the connections at the boiler using a short piece of wire. You can run a boiler without a thermostat in the way you describe, setting the temperature of the water and probably a timer on the boiler too. Thermostatic rad valves can help with that type of system too.
