Data from how many houses did you use when you compared running costs of combi boilers with running costs of traditional systems ?

Bernard, just to get enough water to wash a cup most of the cylinder has to be heated. Cylinders also give off heat in a house in summer, when the last thing you need in the house is heat. Look at the ATAGs with the flue heat recovery. No one sane would install a cylinder when these are available.
The ATAG iC Economiser recycles residual heat that would be lost as wasted energy. The ATAG iC Economiser is the most efficient boiler range in Europe with a 96% efficiency.
Again for you.....
Bernard, look at this ATAG with a 10 year guarantee. 17 litre per/min and with a highly efficient and integrated Passive Flue Gas Heat Recovery Device. Look at their claims backed up by the Energy Saving Trust, April 2017. Why the hell would anyone want to install a cylinder when this is around and it is not the only quality high flow combi on the market either. The Intergas and Ferroli Modena (16 litre per/min) are simpler with fewer moving parts.
The ATAG One Controller is an intelligent wireless WiFi system with an integrated app meaning you can control your heating and hot water from anywhere at any time. Boiler efficiency rating of A+ making it the most efficient combi in Europe

- 39kW: 17.0 litres flow rate per minute.
- 35kW: 16.1 litres flow rate per minute.

come on, surely you can take a stab at it?
How many kWh/day do you think your "high standing losses" are?
Thank you Bernard.
I always thought a hot water cylinder was kept hot ready for use.
I would imagine that a conventional system is inefficient because heat has to be added to the clyinder to maintain its temperature. Whereas a combi doesnt need to do that, but it has to fire up and heat up to temperature all the water required to supply the demand, ie like a hot tap.
I cant help thinking the merits of each system and efficiency are very much dependant on situation. Much more so than than trying to compare maximum efficiency ratings as quoted by manufacturers marketing blurb.
hardwork thinks he knows what it costs to keep a modern insulated cylinder warm.
Strange that he won't quantify it.
If I heat mine on a Friday and go away for the weekend, it is still hot for a bath on Monday.
Hardwork thinks it takes "an eternity" for a modern boiler to heat a modern cylinder. This tells me that his beliefs are based on prejudice and ignorance.
Yes, those things can fail, but with a stored water cylinder a shower is not going to go stone cold part way through, that's the point I was making.
My son had a Vaillant (I think) combi installed 18 months ago, replaced an earlier combi, so no real choice. It has failed twice, seems OK now. Sounds as if ATAG might be better. But don't let's fall out about it, people have different preferences
.Hang on, I know one of the advantages of a combi is no need for a HW cylinder, but you mentioned thermal stores in #21. I was just commenting on that.
Yes please.Interested to know what percentage of my boiler installations a year are actually combination boilers (functioning as combination boilers)?.
Also, what is the difference between "actually combination boilers and functioning as combination boilers"? I don't understand
That would be telling . Hard-On, being such a brainiac should be able to figure out.
Feels strange being on a similar train of thought to Mr D and Mr Green... But at least they HAVE thought about their opinions.

Yes, it looks very nice, but what has it to do with combi vs system boiler, as I asked in #56? It would work with either.
OK, but I thought it was a genuine offer. I suppose there is data available about numbers of different types of boiler sold, if I could be bothered to look.That would be telling

Combi's are on the rise but not necessarily for the right reasons. Each installation needs to be assessed on its merits.
But seeing as you asked nicely... here is one I did earlier:
Not quite finished there obvs.

Look at the new ATAG I linked to.
