How many cups of tea/coffee do you have a day?
Re: How many cups of tea/coffee do you have a day?
I always think that unless you are boiling the kettle outside or its summer, their is little benefit in only putting in exactly what you need as any wasted energy heats the house.
I look at it as limiting the amount of moisture vapour that comes out that produces condensation.

Not only in summer... It's now October and in our old-but-renovated house the heating is still not needed, so there is no point wasting electricity when the (un-needed) heat will leak out after we have left the room.Tinbum wrote: ↑Thu Oct 13, 2022 11:59 am I always think that unless you are boiling the kettle outside or its summer, their is little benefit in only putting in exactly what you need as any wasted energy heats the house.

Agree on minimising causes of condensation though.

AE, i'm sad to report that after goodnes knows how many years of you having the heat recovery vent, (by whom again please)? I wandered into a big builders merchant last week & asked if they had any, ..apparently still to specialist to stock for the two most moisture sensitive rooms in the house.
Modern home builders could cut down this problem by several hundred thousand homes per annum, for a pittance
(taking into consideration renovations, split properties from the slew of subdivided flats from commercial office blocks, etc)

Lots of options, I thought they were grossly overpriced, so I got this one new from fleabay. I suspect someone had bought it without realising its length... I'm happy for it to stick out a bit!
When that bit of 14" brick wall gets rebuilt or we do EWI or IWI it won't stick out so much!
p.s. I think it's the one which is "HTP." Runs on trickle, then can be boosted by the pullcord or its internal humistat.
An acquaintance has retrained as a home energy surveyor... he says that even now the software he has to use to derive the ratings automatically puts in "Add solar thermal water heating" if it's not already installed, so even he isn't impressed by his product...

Re: How many cups of tea/coffee do you have a day?
Bit like our Energy Performance Certificate. This has a bit at the bottom listing things to improve our energy efficiency (bearing in mind the EPC rating is already A107, where A100 is a zero energy home). Adding these "energy saving measures" would improve our EPC rating to A111, apparently:AE-NMidlands wrote: ↑Thu Oct 13, 2022 2:02 pm An acquaintance has retrained as a home energy surveyor... he says that even now the software he has to use to derive the ratings automatically puts in "Add solar thermal water heating" if it's not already installed, so even he isn't impressed by his product...
Ignoring the fact that our house is at the bottom of a deep valley, which makes a wind turbine a non-starter, and ignoring the fact that our hot water is already heated by solar (from the PV), then this is how the sums stack up from those EPC recommendations:
Years to get back the capital investment for solar water heating: Between 61.5 years and 92.3 years
Years to get back the capital investment for a wind turbine: Between 17.4 years and 46.5 years.
It's complete and utter daftness like this that discredits the whole concept of trying to certify energy efficiency.

Same when energy saving trust audit buildings, they come up with ludicrous ideas and ridiculous costs and then copy and paste to another building I use, with different construction build, different heating, etc

I installed ours with the supply isolator in easy reach so it stays switched off through the summer when the kitchen door is open most of the time.
I did think about linking it electrically to the back door, but decided that repeated switching on and off probably wouldn't do it any good.
