Spoke to a Empyre factory rep today and he mentioned Pro-Fab had a bunch of Greenwood GW-100 units available at deep discounts. Brand new units, no warranty. Did some digging and its pretty evident that over heating is a serious problem if the power goes out. Is it worth taking a $3500 risk? I'd probably run a heat exchanger and an open system design with this unit. Payback would be 1 or 2 years at this price.
 
No. It is not worth taking the risk. There is a reason they are not made anymore.

Go to the following company: http://www.secamerica.com/index.php# Order a Surefire SF 512 and install along with your Greenwood. It will run your circulator during a power outage. $3500 is a great price. If you are in the N.Dartmouth area, I know of a Greenwood 130 running problem free in its 4th season that you could go look at. I have been running a Seton 130 for one season.

I'm in Dartmouth. I'd love to see some local set-ups. For the record, the Greenwood scares the c$@p out of me. But the price is so attractive.

Price is $429+shipping from http://www.altheatsupply.com/manufacturers/index/products/manufacturer/95 . They are one of a dozen or so dealers of the unit. Others dealers are at this page: http://www.secamerica.com/distributors/index.php

I'm sure it would, I don't know for how long though, I guess it depends upon the draw of the circulator and fan, and the capacity of your battery. You'd have to do some math.
 
Not sure why this style of boiler would overheat any worse than any other style if the electric goes out.

As far as the price . . . depends where you want to be in a few years. The lack of warantee is meaningless. There was no warentee when the 'original' company was solvent.
 
Took a look at Greenwood 200 yesterday and my 1st impression was that it was built like a Tank! My next thought was that the unit needs constant monitoring based on the outside temp to prevent overheating. The system doesn't have controls, so the aquastat was being lowered manually. Not sure that I want to be constantly monitoring settings. I must say that the firebox was super clean due to one chamber achieving high temps. It was all white like a lower gassification chamber. The operator had a dump zone hooked up to a modine heater and was being used while I was there. The battery back up was also installed as a safety precaution. Unit has been in operation for 4 years and has had any issues since the dump zone was added. Prior to that he had a blow out that shook the house.
 
Part of the appeal of this style boiler is the lack of controls/settings. It is 70's here this week and I continue burning 'cause I am too cheap to use oil for DHW. The only "adjustment" that is required is to make sure you load appropriatly. Quantity and quality.

I'm sorry but I just don't understand why people are hitting dump zones unless the electric goes out. I finally got the automatic transfer generator operational, so that takes care of that issue.

No question that these units shine when it gets good and cold out.
