I did not suggest for one minute it only came on for 5 minutes per hour for 24 hours a day and that we had mega low bills. I believe we pay about £60 a month.
As stated I was just making the comparison of what I have observed in terms of our central heating running time from morning onwards when it is left either on or off during the working day. Therefore, as stated, for our house, it would appear it makes very little difference whether we turn the thermostat down during the day or not.
I have a vailliant condensing combi boiler and I usually run it at about 60-5°C for the CH set temperature. If it is really cold (0°C or less outside) I might increase in to 70°C. When I first put it on and in the last month it is on I try to turn it down to 50°C.
I understand that the condensing boilers give the highest efficiency at lowest CH return water temperatures, which is why it is often recommended to fit oversized radiators and the most efficient installations are when they are linked to underfloor heating systems

It's not 5 minutes then every hour to 1.5 hours then as you implied. £60 a month buys about 20,000kWh per year of gas deducting 2,000kWh for hot water leaves 18,000kWh for heating so that's 100kWh per day for heating for 6 months. So about 4kW per hour for heating just a little bit more than my average at 3kW per hour for heating. A 15kW boiler would then run on average for 16 minutes per hour (384 minutes per day twice your estimate) and closer to your original estimate of 15-20 minutes per hour. It's about the same as mine 5 minutes on then 15 minutes off on an average mild day but then my boiler only takes 30 minutes to heat from 12 to 18 degrees and not 2 hours from 14 to your room temperature. Are you sure it takes 2 hours to heat from 14? That's a long time. You are right in that it doesn't make a huge difference but some quite reasonable savings can be made by turning the thermostat down when sleeping and when going out. My bills when using gas are about £30 a month using the timed method. I leave it on all day when home on weekends and holidays. So as I said earlier 24/7 is 72kWh per day and timed is 30kWh per day. I read my meter very regularly and use iMeasure to compare usage against the heating degree days.

It does sometimes just click on for 5 minutes if left on. That is what I said because that is what it did, I timed it (it was lunchtime and I was bored) to make the point that it clicks on and off rather than just running and guzzling gas. I did not use that as a generalisation and quite clearly said 15 to 20 mins was typical. Please re-read what I posted as you have clearly misunderstood it in the first place. It was a direct observation whilst working from home of what my heating does when I'm here versus what it does when I am in the office. I wasn't expecting the spanish inquisition....... no-one expects the spanish inquisition:rotfl:
As an ex Gas Fitter(proper time served Gas Fitter not the quick qualified money grabber service engineer of today) I over the years surveyed customers on their thoughts on this and it varied somewhat.
Let me get this straight. You, as the expert, are asking the opinion of your customers to figure out how heatingsystems work?:rotfl:
Mr Ted I have just noticed your angry reply, are you intent on spreading your nasty pearls of wisdom across the whole forum? You're ranting over BG wanting you to pay for your usage (good god whatever next, how dare they!) and now you're laying into people for wanting to make money out of their business! May I suggest if you have nothing but venom to share, DONT! As for you wanting to live in a utopian world where business is a community project may I suggest a move to a communist nation.

Ex money nightmare, learnt from my mistakes and never going back there again, in control of my finances for the first time in my adult life and it feels amazing.
:mad:
Dont be so facile, it only becomes a person that doesnt care about how their customers efficiently use their systems
I explain in detail how things work BEFORE the work is carried out so that the client can make an informed decision. I don't have to ask them what they think, because I KNOW how it works.
Apart from that, my customers will find the system set up to best performance, so they don't have to worry about it. If they do want to know more because they forgot or didn't quite get every detail, there is ample information about how it works on my website.
If you really were a qualified RGI, you would know the same. But judging by the amount of nonsense you have posted here, you are no more a RGI, than I am a supermodel.

Hi Naomi
If you read properly you will observe or deduce that I asked customers how they used their systems in respect of GAS USAGE and COST in the way they set and used their systems, not to find out how a system works :rotfl:
You would also have noticed I say quite clearly I am an EX gas fitter, as I am now retired, and I have also posted on a post to clarify my array of knowledge and experience in the industry, but I dont intend to do it again, Specsavers have some good deals on to :T
That is what the OP is about isnt it, not how a system works but how settings affect cost, or was, just because opinion varies does not mean that it is not correct for THAT person
What i said primarily is factual, to me, who are you to say it isnt, you dont know who I have spoken to or what i may have asked and they have said in response:rotfl:

Of course these days to socialise with customers would cost you more profit, how long would it take you to service a boiler, 5 minutes?

That is communistic and self rightious!
