For others who answered this question partially, isn't Testro's point more that letting the house drop to say -2 and then trying to get it back up to 15 every morning is more power inefficient than burning a steady stream of heat to get it there once and then maintain that temperature?

Isn't that an insane thing to do though? You still have to live in your house at night even if you're under a blanket, so it should be at a liveable temperature, and as Testro says it doesn't save any money to fluctuate wildly.

The house requires the same amount of heat either way, but it's more efficient to run boilers at lower temperature . That's if you have a modulating boiler, otherwise it should be pretty much exactly the same just way more comfortable to keep it constant.

I guess most people (?) sleep upstairs and heat rises so you could min/max this a little further but doesn't seem worth it.

But that's the problem, some people don't realise the cost efficiency to be made there - they see "heating being on" -> "I'm bleeding out the arse to pay bills" and end up freezing themselves.

I've just been having the heating as on/off all the time. If I want to tell the boiler to just keep it at a set temp and leave it running overnight as well, would that save me money with a combi boiler? What temp should I tell it to go to?

Combi-boiler makes no difference, that just means it heats up tap water as you need it, rather than having a big tank in a cupboard.

The real answer to this is it varies - depending on your insulation, neighbours and so on - the only way to find out is to do the heating both ways and measure how much gas you use.

Gotcha, thank you. What do you think a reasonable temperature is? Somewhere in the 15c area? I suppose I'll just have to test that too.

Building regs I think advises 18 degrees for bedrooms and 21 degrees for living areas but humans are very variable in their preference, and things like drafts make a gigantic difference to perceived temperature.
There are so many variables there's no universal fix to heating strategy, apart from moving into a very modern structure that Persimmon didn't build.

That seems pretty chilly tbh. Personally I think 18-20 is a reasonable temperature for rooms you actually live in, if there are bits you aren't in much you can let them drop a bit lower. I think there's some evidence 16 and lower can lead to/worsen respiratory conditions.

e: I'm visiting my folks at the moment and their kitchen is sitting at 14-15 which is not very pleasant. Not by choice though, it's just an old house with crap insulation.

No it isn't, but it still tramples my bloody lavender.
I'm keeping the thermostat around 16-17C which is read from the hallway which is warmest- rest of the house is more like 13-14C or so which is alright, running two dehumidifiers helps keep it a bit comfier

I'm afraid that is just introducing a new, even more confusing concept.

I know people say farenheit between 0 and 100 is supposedly a quite human range but my temperature range is like, 0 to 50c, which is apparently 36 to 122 farenheit.

I assume it works better in places where it gets colder than 0 regularly.

Sorry I thought you were a landlord when I gave you your old avatar!
My bathroom towel rail oscillates between 18C & 19C so I've kept it on permanently this week.
It turns off at 19.0C and on again at 17.9C. I didn't use it at all last winter!
I definitely notice when my living room goes below 18.5C.


Fahrenheit chat:
As I have quite a lot of American friends, I'm forever having to put dual temps on weather-related posts:

C = (5/9) (F-32)

F= (9/5)C + 32

0C = 32F, 0F = -17.8C

Both temps are the same at -40 (ie minus 40 F = minus 40 C).

80F (26.7C) is beginning to feel uncomfortably hot.



Fahrenheits should get in the sea along with 'cups'. Another thing Americans always go on about instead of nice metric amounts.
Having said that, as a child in the60s, recipes were almost always by volume (usually tablespoons level or heaped) rather than weight so I can kind of understand using volume measurements has a purpose.

It works best in places where it never gets colder than 0 and never gets hotter than 100, because it was invented for meteorology in coastal Europe.

At the time of Fahrenheit's highest use the centigrade scale (as Celsius was) went from water boiling at 0 and freezing at 100 and so made gently caress all sense to anyone.

It's one of those weird quirks that the few places left that still use F aren't the best places for it.

e: ^^ A metric cup is 250ml, there's four in a litre. That's a measure by volume against measure by weight debate rather than a metric vs customary debate.

Fortunately, we are a gas-free building. It's just this bad cold (that I have - not the fact that it IS cold).
But yes good to remind everyone!

With the current weather i have the central heating on continuously and the hall thermostat set to 14C (it goes on for 3-5 minutes every 1/2 hour or so).

Keeps the house acceptably tolerable to move a round in and if i close the living room doors that room goes up to a pleasant 18C.

If I had a house in this country if possible I'd install a 2. 5kw mini split system in a bedroom at least. The one we have in the bedroom in our house in a cold part of Australia (down to about - 7 overnight in winter) uses absolutely gently caress all power (about 400 watts) and heats the room in a few minutes. We run it entirely off a solar battery system.

Also has the benefit of being able to cool in summer.

Technically you should save a bit of money doing this since the amount of heat lost through your house's exterior envelope (walls, windows, doors etc. as well as air leakage) is a function of the temperature difference between inside and outside. Spending more time at a lower temperature means fewer losses from the heat energy you are generating from your boiler, overall.

I'm not sure of the magnitude of this saving, and you should also consider that it's probably gonna be terrible for the maintenance of the house doing this longer term - lots of interior and exterior materials, both of the house itself and e.g. your furniture, plus things like musical instruments, will hate these conditions. Things expand and contract with variations in temperature and also other porous things like wood and plaster hate large swings in humidity, which is something that's probably gonna happen with changing the heating like this, and so it may be the case that lots of things in your house start to crack and fall apart.

In fact, I've thought about it previously - when you see an abandoned house, it goes to absolute poo poo within a few years, starts literally crumbling and falling apart, but if you live in a house, even if you do *zero* maintenance to it, it'll last a lot longer. I think one of the big reasons is that an abandoned house is unheated, and therefore swings sometimes 20°C in a day-night cycle which accelerates the decay.


Edit: Oh yeah the whole thing about maybe the boiler is actually less efficient at lower temperatures? Not sure. I'll ask my wife about it when she's finished work - she's a building scientist looking at home energy efficiency stuff so this should be right up her alley!

With condensing boilers at least, this can come back around to bite you in terms of efficiency.



3-5 mins isn't too bad at all, but if it starts only coming on for 1-2 minutes you can start losing big chunks of efficiency.

Use a builder's smoke stick or a natural herbal smoke generator of your choice. You can often just feel drafts with the back of your hand though. I've got masking tape around all my 1990s bodgit and scarper UPVC lovely tilt&turn windows for this reason.
