The Portage & Main BL 2840 we purchased from Strawbale Farms is a great unit. This is our third year running it and the performance has been 100% accurate. We previously owned a Woodmaster 4400 and the Portage & Main is a far better boiler in my opinion. It burns hotter, cleaner, a lot less wood and very easy to maintain. I wish we would have purchased a Portage & Main to start with. It is a very high quality built unit. We are 100% satisfied with our BL 2840 and the great customer service. We would definitely highly recommend Strawbale Farms and Portage & Main Boilers.
