Heating on low and constant better?

TITEASCRAMP

Why dont you read up on how new condesing combi work. I am not being rude at all.
Honestly i have tried it both ways. It came out the same usage (units per day). Plus its not on constant because during the day my rads are cold.
I can only go off my boiler and house. The house is more pleasant this way.
Sorry i forgot i am in coz i dont work.

It is without dispute that the house is 'more pleasant' but don't you sleep at night?

Shutting the heating off at night will be cheaper than leaving it on!

If you go away for 2 weeks do you leave the heating on constantly?
If not, why not?

I am not disputing your findings, but the method/conclusion, you don't have control of the outside temperature or the sun or the clouds, so cannot compare one week with another properly. In an identical environment, you savings would be less pronounced than a non-condensing boiler because you have an efficient boiler and trv's, but I would still expect you could maintain the same comfort, and save money by only heating when you are in (or about to come in), and awake.

I will say of course outside temperature plays a part most definately. I will continue through winter and compare them to last year. If im wrong i will still come back and let you know.

Of course i would because no one is here to feel the benefit.

Titeascramp,

Because of your (and the op's) stay at home situation, and efficient system, then the savings for you aren't going to be massive, but it is still wasteful heating up the house whilst people are in bed wrapped up in a quilt, and for people who work during the day, even more so.

Many people (thinking it is cheaper) do leave the heating on 24 hours when they don't need it for 16 of those hours, so that is the common myth we were trying to address with the kettle and holiday analogies.

The bottom line for people who work is that it doesn't take 8 hrs to warm up a cold house with central heating, more like half an hour, and the hotter the house is compared to the outside temperature, the faster it loses heat, the more you have to reheat it. If you are doing that when you are out at work, or in bed, the boiler will be cycling on and off constantly, and that is wasting money and not adding to the comfort level.

I have a brand new condensing system; this in my opinion has to be a factor. Another analogy then - You travel 500 miles in your car without stopping and 500 stop starting. Which journey do you think cost the most in fuel?
The weather this wk has been the same all wk. I have done the test both ways yesturday 7.5 units on constant, on timer only 3hrs usage 8 units.
It must be down to the system. My boiler is reusing 90% of its gases.

What are these units?

Units of usage on the meter

Yes I had gathered that but is it a metric or an imperial meter? Units are meaningless unless we know what the units are.

Must be metric because it was only put in about 6 months ago. Sorry I didnt know what you meant.

That is exactly the pointless type of analogy that feeds the Urban myths! It is like people who state that leaving lights on 24/7 is cheaper than switching them off when you leave the room; because lights use more electricity when switching on.

The Government has agencies like the Energy Saving Trust whose sole objective is to advise individuals and organisations how to save energy and hence money. They specifically say you are wrong.

The laws of Thermodynamics say you are wrong.

If you feel your Condensing boiler defies the laws of physics why not ask the manufacturer for his advice - or any organisation if they believe your theory?

.

I assume you mean of course I wouldn't?

Well if you have it off for the 2 weeks it is presumably because you think it would save energy and money?

Is it so difficult to grasp the concept that if it saves money having heating off for 2 weeks it will save money having it off for 8 hours overnight?
