With our biomass furnace ratings, you can compare furnace models side by side using our Head To Head tool.
You can compare the different models from the major brands in 12 categories such as warranty, cost, fuel source, & where they are made.
You can also read the individual reviews of each brand below.
Our simple rating system gives each brand a color code and a star rating. If the card is green, then, that is one of the top picks from HvacRepairGuy. If the card is yellow, then, that would be a budget pick from HvacRepairGuy. If the card is red, then, the brand is not recommended by HvacRepairGuy. With our wood boiler reviews, you can cut through the sales hype and find value. It truly is like you were taking a repairman shopping with you!
This brand is made in the USA by LMF Manufacturing and is sold through a limited dealer network. The furnaces are available in two models AH100 which has a 100,000 BTU heat output and the AH 170 which has a 170,000 BTU output. The units burn shelled corn and have a modulating control that adjusts the corn and air flows to very closely match the heating setpoint. This can save fuel as well as improving the home's air quality by having longer heat cycles. They are factory wired for the addition of air conditioning but the hopper for storing the corn is not integrated and the warranty is not as good as some of the other brands. The units require manually lighting the fire at the start of the season and then they continually operate on a low fire setting which is not ideal for efficiency or comfort.
This technology is licensed to Maine Energy Systems from OkoFen and the units are made in the USA. The Autopellet Air units are wood pellet burning furnaces that have a fully integrated room temperature sensor that modulates the air flow as well as the burner to maximize comfort and efficiency. The furnaces have a touchscreen programmable control with Wi-Fi access and an ECO mode where the unit varies its operation based on the local weather forecast. They offer various sizes of silos for storing the fuel and feature automatic feed, ash removal, and heat exchanger tube cleaning. The brand is backed by a good guarantee but is only available through dealers in parts of the USA and Canada.
