I'll get a bit biased here for a moment - but even though it is likely pretty hard to do, try to picture yourself in the future after you've installed the boiler and are now in the living with it phase. That is where ease of maintenance and how much of it there is comes into play - and a nominally larger initial sticker price becomes less important, or maybe even worth it. I have only experienced living with mine (speaking of gasifiers), but even with how easy it is to clean & maintain (don't think there are any that are easier), I still sometimes let it slide longer than I should, or it's still a drag thinking about having to do it, even though it only takes 5 minutes. The thoughts of having to take panels off &/or go through more hoops than I have to now makes me more glad I got what I got - even if I might have found a bit less expensive boiler at the time. Varms don't even have door gaskets on them - another thing not to worry about that others have posted about chasing at times.
