yes, and too noisy and too much maintenance. These are exactly the

While the AC version is significantly noisier than a modern boiler,
careful siting or enclosure design can make this a non-issue. I've
slept within a few feet of a DC version (slightly quieter) on numerous
occasions and despite the total lack of added noise insulation its
never been a problem (some of the sleep was alcohol assisted though!)

I can only vouch for a couple of units I am immediately aware of (both
marine installed DC versions) but maintenance required for around 2500
hours of operation has been very minimal over the past 4 years,
certainly way less than any internal combustion generator on a similar
duty cycle and probably less than a typical gas fired central heating
boiler.

I still think a condensing boiler is a significantly better option for
the majority of households though.
