High gas usage for boiler.

[stevedurban]

Dumb can be the smartest in the end as long as you don't need room temp control to the nearest 0.1 or 0.2C.

So that was tados opinion - and the reason we made it so that only downstairs can call for heat. The others TRV’s are just set so that the rooms are not too hot.

I found when we knocked the bedrooms down lower (or turned them off during the day) - the downstairs zone was working harder/longer - I presume trying to bring the whole house up to temp - without the radiators in bedrooms etc helping!

Where is the stat placed ?

How many rooms are you maintaining at 21C, the whole house?.

Yes - bedrooms - bathrooms are 20/21 - but they can’t call for heat. They just make sure the rooms do not go over 20/21

We had it in the hall way for a while - but now moved into lounge a middle wall of the house - centre of the room.

Why not use normal trvs are they connected to a hub ?

I put them in because originally - when I was trying to get ontop of the high gas usage - I programmed them to be off all day in the bedrooms and upstairs - as we obviously were not using them. But when I realised it didn’t affect the gas usage - and if anything the house felt colder and was struggling to heat - I just turned them back into dumb TRV’s basically.

And if you turn heating off but turn let’s say upstairs bedroom with a tado trv in on the boiler doesn’t fire ? Might be worth a test

Correct - in the tado app - you have to tell each room which controller to use to call for heat - or you can set “none” - which is what every room other than “downstairs” is set to.

I suppose, at the end of the day, if one is keeping the whole house including bathrooms at 21C then one one can expect high energy demand, I consume ~ 15,000kwh (oil) per annum but if I heated my whole house to 21C I would expect ~ 22,000kwh

Id probably be happy with 22000!!!

Thanks for all your helps Guys! I sense we’re running out of road and I just need to accept my house now takes a lot more to heat!

Global warming? (Manchester is global cooling I think!)


Just one last question if I can - is there anything in the boiler that - if it wasn’t working properly could be causing it to run/burn more than it should? taking the view that 3 services have all found the basics to be ok (eg the oxygen/gas mix etc)
