Replacing Combi Boiler

Nosmo_King_2

I have been quoted £1500 to remove existing combi and replace with a Baxi Duo Tec 33, this includes flue-kit, outside drain, 1 litre inhibitor and registration of installation (does not include flushing as prob not necessary?)
I can source this boiler and flue for just under £800 through web based supplier.
Does this quote seem to be reasonable?
Also suggested that a Vaillant Eco tec +831 may be a better bet but would be £270 dearer (I can source for around £930)

Good morning: See the Duotec's installation guide for requirements....the need for a flush with appropriate chemicals is clearly detailed. I'd recommend the Vaillant Ecotec Plus or, for a bit more, the Viessmann Vitodens 200 (5 year warranty if the RGI is Viessmann trained). Btw...material costs are not represented solely by the boiler price.

Thanks for that, we have just received another couple of quotes, the best of which was £1450 for the Baxi duo-tec 33 and £1550 for the Vaillant +831, the price includes flushing but there would be an extra £100 for a programmable stat. (we already have a Honeywell CM5000 fitted but apparantly it may not be compatible).
None of the people we asked for quotes wereViessmann approved installers but looking at the prices of the boilers I think they would probably be out of our price range anyway, and SWMBO would kill me if I arranged for more gas fitters to visit! (and delay start of installation.). .
thanks again.
Quick update, having a Vaillant +831 fitted for £1435 (RF thermostat extra £100 but may not be needed)
