What temperature do you set your thermostat?

[stephec]

Me personally it would be set to off, Mrs stephec is more like 21°C.

We set the Hall thermostat to maximum and have TRV's in on every radiator - these we adjust as necessary.

So what stops the boiler if all the radiators are set below the max on the thermostat, wont the boiler keep running ? or am I missing something here.

There shouldn't be a thermostatic rad valve in the area where the room stat is fitted. This is potentially dangerous, if the thermo valve shuts off in this area at a lower temp than set on the room stat, you' ve removed the overheat shut down & then reliant only on the internal boiler overheat stat. Not a great situation if the boiler stat fails in this scenario, it keeps on running to excess temperature because the room stat is still calling for heat with the adjacent rad shut off by the thermo rad valve.

I thought that there has to be one that doesn't have a TRV?

we actually have 2.
downstairs cloakroom rad and loft bathroom rad/towel rail

If I turn my roomstat up to maximum the room temperature goes up for an hour or two, but then the boiler just turns the water temperature back down anyway, and the room temperature comes back down with it. The controller's programmed to override anything you can set manually.

I've recently discovered that if I have the roomstat set to a constant 20C, it sneakily readjusts that back down to 19C after a few months too. The first time it happened I thought I was imagining things, but I'm not, it's just done it again a few days ago. It seems to be testing to see if you notice the difference.

My theory is that once the air space is warm you also warm the walls,the floor and everything thing else inside it and it's cheaper to maintain that temp as opposed to blasting the boiler at full wack when the house is stone cold.

We've been on solid fuel heating up until 2-3 months ago so we're still getting used to everything but have been experimenting with the thermostat to see what is most efficient and also where to place it. The most efficient seems to be leaving it on 24/7 with only little variance between the day and night temp which equates to 2+ hours less heating used then if it only comes on in the morning and night.

Maybe the controller software programmer suffered from OCD?

I am only partly joking - a member of my family insists that her TV volume is always set to an even number... Maybe something like that!

Same here - can't stand odd volume numbers.

I think it's a widespread thing with TV volumes.

It's possible for this to be true *if* your heat source (boiler) becomes a lot less efficient at high power outputs.

But basically heat loss is proportional to (inside -outside) temperature. So you lose less heat if you allow the temperature to drop.

So it's very unlikely to be true in your circumstances.

Mrs B is a bugger for turning on the thermostat. Fortunately our gas meter makes a sqeaking noise when gas is being supplied, so I hear it and if I am working in or passing through the garage, I have an app which controls the thermostat.
At our previous house, Mrs B used to occasionally babysit for a couple who had the radiators removed from their house, because they never used the central heating as they found the house too hot with it on. Which was weird as both houses were detached, about 400 meters above sea level and they didn't have an alternative heating system.

None of this new angled Fahrenheit nonsense in the Drago house hold. It's currently 188° Galileo here, really chilly.
