getting to be a pain, we had a new boiler fitted a few years ago, it's a vaillant with a wireless thermostat control, when put the heating on timed it doesn't seem to care, when it's off for the night it comes on whenever it likes, it's even come on during the summer, the wireless thermostat has read 29 degrees before now and it's still firing up and heating the entire house, we keep the wireless control in the warmest room as plumber said would help!
even if switch the heating off, as I did through the summer it'd still come on at ridiculous times!
the only way have found to stop it is by turning the heating on the boiler itself down to pretty much zero, setting times on the controller does nothing to stop it, I want it to come on when I want it, not have it firing up at 3am because it decides it wants too, there's no logic to it, it'll fire up in the day as well, have come into the house before now thinking walked into a tropical rainforest it's that hot!! I don't want it blaring and heating when don't want it, I also don't want to have to manually go turn off all the radiators because it decides that 29 degrees just isn't warm enough!!
help, am dreading having to turn it up again as colder weather looms, apart from anything else when it decides it'll just turn on when it wants it uses a ridiculous amount of gas, the 'base' temperature that it's set to come on at if falls below is 10 degrees, it's never been that low on the thermostat for that to cause it to kick in, even in winter?!!
