Any combi boiler deals on ?

SailorSam

I've just had a new combi fitted an Ariston with a 30kw output, it cost £1850 and comes with a 5yr guarantee. Like you Op i'm in a fairly big 3bed semi and found the old Ravenheat which was 28kw rubbish at filling the bath.
I think i could have saved money by getting the boiler myself and then looking for someone to fit it, i saw a couple of boilers with the same output i've got for £700-£800 and thought i may pay about the same for fitting, but what i was worried about was if there was a problem at some time in the future the suppliers and the fitters may start blaming each other ..... so decided it was best to go for a supply and fit deal.
Although the boiler i've got seems a bit more than i was expecting, i decided the 5yr guarantee would save me perhaps £800 or more in insurance, so not such a bad deal in the long run. I asked if i was to move could the guarantee be transferred, and yes so again it could be a selling point.

Thanks for that input. Seems like it would be more sensible to let the person fitting it provide it. Can I ask which model did you have installed ?

Can you clarify this "i decided the 5yr guarantee would save me perhaps £800 or more in insurance, so not such a bad deal in the long run.". Not sure what you mean buy this ?

If you put a 24 kw output boiler in I would say the flow rate would be an acceptable 11 litres per minute at 35 degree increase in water temperature.

errr i think not, a 24kw combi won't supply 11 ltrs/min at 35 degree rise

Won't it? What about the Worcester Bosch greenstar 30si is 24kw and does 12.3 litres per minute at 35 degree.

Hi...you're confusing the heating output with the DHW output i.e. the WB is rated @ 30 kW for hot water, 24 kWish for central heating. Tech specs here.

Ooops - thought i was getting good hot water flow rate from my 24kw boiler :laugh:

Ok will ask it does seem as the water pressure is quite high in the house.

'Quite high' is meaningless-the pressure/flow needs to be tested and assessed for suitability. Let your GSR RGI recommend and source the boiler that he's going to fit.
Same applies to your existing gas supply pipework-is it suitable for a combi?

The guy who has been maintaining the existing boiler seems to think a combi boiler is ok. Isn't it just a case of the pipes might need to be a little bigger ?

He has not produced a detailed quote as yet so I dont know all he has in mind.

Going from a coventional boiler to a combi isn't just a case of changing the boiler, a lot of pipe work will have to change and be added.

I'd be going for a system boiler and an unvented cylinder.

And with regards to make a model, it will only be as good as the installer who fits it. Letting the installer fit one he is used to is beneficial because he will have experience with that particular boiler.
