I'm aware the gold standard on the Irish market seems to be the Grant Vortex. However I've also been advised that the Warmflow equivalent is the exact same (same internals) but much cheaper. Looking at quotes for each there's a difference of about €450 (not an insignificant sum). The specific boilers I'm trying to compare are: Grant Vortex 90/120 (26-36KW) Warmflow Kabin Pak K120HE (26-33KW) What are people's opinions of Grant Vs Warmflow in general as regards build, reliability, lifespan, servicing etc? And of those particular models above? Any help or advice from experience (installers and/or users) appreciated.

Paremon wrote: » Thanks. So is the concensus that Grant is better than Warmflow based on anything in particular, eg spec, build quality, reliability, average lifespan, etc? I've also been recommended Firebird which i believe are an Irish company. How would they compare to Warmflow generally? Re kw; I've had the rooms measured by an installer for a quote & they came back with 26-34kw & the above boiler examples. Same for N another installer/quoter. I then calculated myself for my own purposes each rooms' area (lxhxw), without taking into account wall depth, ceilings etc added it up & after conversion it came to 23kw which i took as the minimum to heat the house. As that's just a minimum & didn't include wall depth, ceilings etc & as there's very little wall insulation i added a bit to that & can only approximate it to around the 26kw mark. Is that a logical approach? What are the disadvantages of oversizing the boiler vs undersizing? Re rads; 12 in total, non convecting, some double, some single. Intending to replace these with convecting rads with TRVs. Will be insulating some parts of the house (attic, 1 cavity wall & some small internal areas).

DGOBS wrote: » I would compare the build up in the boiler to that of a gas boiler, much less than an oil boiler. But take the commissioning point too. I wouldn't say they will be much more expensive for long (as not a whole lot more to the the burner to be honest) Would say they will become the norm rapidly.
