I see this site lists New Horizons (Eko Line) and Greenwood boilers, but I couldn't find any posts about these on a forum search. I want to use an efficient outside boiler (gassification type, not the kind that belch smoke) to heat my sprawling house, but I'd like to get input from somebody who has actually used one. I've seen comments about Greenwood on other sites (woodheat.com I think) - they certainly do have an aggressive marketing dept - just try giving them your phone number - and I've heard another manufacturer is suing them for patent infringement, but that of course says nothing about the product's efficiency or reliability. I think they're very new so don't have a long track record. New Horizons Eko Line is made in Poland - I can't find anything negative about them and I think they've been around awhile, especially in Europe. but the tech info on their site is obviously poorly translated from Polish (I studied Polish in college and can see how a Polish speaker who wasn't well versed in English syntax would make these errors - sometimes incomprehensible). New Horizons says they're used extensively in Germany. Anyway, has anybody used an Eko boiler or know somebody who has used one??
