Hi, Before I begin, can i just say what an excellent forum this is. I have had several issues over the past 6 months regards firstly buying the Evohome, then setting it up with my current boiler set up (Currently Y plan). Now hoping that you guys can help with the next stage of my decision.
I share a 4 bedroom detached house (medium sized) with my wife (just us for now), having repiped and renewed the radiators I am at the stage where I can finally get rid of the 1986 boiler and open vent cylinder set up. The new set up will consist of a system boiler and unvented cylinder to be relocated to our attached garage using the S plan arrangement in the honeywell instructions with one zone valve to the HW and open CH circuit for the OT - all rads to have HR92's. I have found the heating engineer i wish to use - knowing a few plumbers that have done work for me over the years, this chap is the only one i really trust to do this build for me as he's actually interested in the actual end product rather than just fitting for fittings sake - he also does a great job having seen his work elsewhere.
The system will consist of a Gledhill 250 litre cylinder which should work nicely with the planned smart showers I will be installing. The problem is which boiler - my heating chap recommends WB (obviously no OT), Viessmann and Vailliant in that order (aiming around the 30kw mark). I have everything to set up my Evohome for OT and plan to go down this route - with my research and based on these boilers all being around the same price, I have discounted the Vailliant given the requirement for the VR33 which tips it over the price point, and based on the fact it is my engineers 3rd choice. Long and short of it is I have narrowed it down to Viessmann or Intergas which my installer has never fitted before. I completely understand the issues with Viessmann with the over shoots/lack of limiter and know this is something i would have to put up with - having emailed Viessmann they have confirmed they are working with Tado to enable Tado to integrate an upper boiler temp limit but this will unlikely affect Evohome as it sounds like they are helping Tado control their boiler as opposed to reinstating their own limiter. The Intergas for me is the easiest option especially given the reviews...
My installer is understandably not keen on fitting the IG, preferring the Viessmann not least for the 10 year warranty compared to the IG which would only be 3 given he isn't a platinum installer. I have also read that the IG boilers don't do very well in hard water areas and have read many reviews online around failure in this department - where installers have fitted water softeners and they have still failed with no support from IG despite the warranty. The Viessmann rep is suggesting the benefit i will get on OT will be minimal, therefore I should just use the standard BDR91 switching - something I don't really want to do, i want to use my shiny Evohome to its max potential!
So this is where I am - I want the Viessmann for the warranty, I completely get the Intergas system but with 3 years warranty, it's more of a gamble.
Can I have some opinions please
Thanks
