Pellet Duo 40 Boiler

I am very pleased with my new boiler. It is a well-made little unit and was delivered to me complete and damage free. Two mentionable items. First, I had to swap the wires going to the flame detector, other than that the system started and operated perfectly. Secondly, the design of the hopper is not as advertised on MBTEK website. It is unpainted galvanized metal construction with a slide open lid not a hinged lid. I like the design, no complaints there, I’m only pointing out that it’s not what I thought I was getting.
I’ve been operating the unit for about 3 months with no issues. I went as far as to purchase wood pellets from every big box store around and the unit performs the same using all of them. I have even operated the unit on 100% Cherry Pits, and it operated flawlessly.
The one feature that I was really looking forward to, was the ability to use firewood as a small supplemental heat source. I started a firewood burn twice now, just for fun. It does a good job controlling the solid wood fire. I was pleasantly surprised. My only complaint is that, at the end of the burning, I have to manually switch the unit to pellet mode. I hope that there is a software update (or I figure out how to set it up properly) that it will allow the unit to automatically switch over to pellet fuel after the solid wood fuel burns out.
Lastly, I would highly recommend MBTEK. They have answered several of my questions in a timely manner and are very easy to contact.

Duo 40 pellet boiler

This boiler may take a while to get here. It takes some time to learn and perfect. It's not cheap.... But it's worth the wait. It's worth the expense. Well built and well thought out. I am pleased with this purchase and would highly recommend to a homeowner who is mechanical an tech savvy. If your the type of person who likes to tinker with things your gonna love this boiler. It's not plug an play, it's a totally customizable system that you fine tune to your homes personal needs. Get a professional heating /plumber to install this unit an be sure to get the ecoster thermostat with your unit. I bought this unit to replace my hot water oil burning furnace because heating oil was 5.95 a gallon. I use about 1200 gallons a year. This duo 40 has paid for itself already. A real work horse so far. I can't say enough about the quality of build on the thing. I was skeptical to purchase from a foreign manufacturer,but everyone who sees it in action all say the same thing, " dam nice piece , impressive". In addition to all of that, I can keep all my fuel expenses in my local area instead of buying from big tech oil companies all over the world.

This is a great boiler!

This is a great boiler! I have the Pellet 40 and it works great and it's well made.
The only improvement would be to the support staff. They would not help me work through the problems I was having. I'm the homeowner, they wanted to deal with the professional installers. I had a plumber hook it up but I had to figure out the wireing and the instruction books are a little short on explanations.

Excellent Boiler

I love this boiler. I owned a gasification wood boiler before this which was a great boiler. This boiler out performs that boiler and is much easier to maintain. Plus I can run this boiler much sooner in the heating season without fear of the unit over heating on warmer days. When the boiler is satisfied the heating stops, very little temperature over run. I have never seen the stack temperature reach 300 degrees fahrenheit. My gasification boiler would reach 550 to 600 degrees. The controls are very easy to install, set-up and use. The hopper holds about 15 40# bags of nice, clean dry pellets. I no longer have to haul in dirty, snow covered wood. Love it!
