Just recently had a Greenstar 28i boiler, all new pipework, 8 rads, heated towel rail and thermostatic mixer shower in my 3 bed detached house, boiler in porch, trv's on all but bathroom rad.
Previous system was indirect with very old Foor standing Potterton gas boiler with timed hot water and a tank stat.
Its been in about a month now and I have been keeping tabs on the gas usage, the CH has only come on for a short while on 2 very cold evenings so my figures really are for hot water use only.
55 pence per 24hrs is what I am seeing and thats a saving of around 70 pence a day on the old system! We cook with gas too.
I almost wonder if the plumbers broke the meter when connecting the new gas supply!
There will I hope be an added bonus of the drop in my Electric bill due to the fact we were using a 9kw electric shower before the change over and we now have a really nice mains pressure gas powered shower.
3 women in the house so the shower really does get some stick, had to remove the radio from the bathroom to cut the amount of time the girls were spending in the shower while on electric!
The only negative I have seen is a slightly long time to get hot water from the taps, but then I did elect to have the boiler fitted as far from all the taps as possible
but with the programmer I have fitted I can use the timed pre heat to cut that somewhat.
Almost cant wait for winter so I can see what the savings are there
