Chase - I’m looking into these units in NJ also and would like to compare notes.

MY GW100 will be operating two year come January. This summer we are running it a lot for DHW. Just my opinion, but GW’s servce sucks. The unit itself seems fine, except that the refractory cracks - probably from thermal shock - too easily.

Depending on whether I have to buy wood this year, my payback should be about April 2010. Would I buy another? Maybe. But not until I was positive that the Vitolig200 was unavailable.

I have a Seton 100 on line for one season. I have no refractory cracking issues. My unit, though, was not put together very well and leaks at a lot of the seams. I will need to seal it up somehow. But overall, I am impressed with unit. It has a lot of potential. The best feature is the whole logs that it burns. Not splitting and stacking means a lot less work.
