With our biomass boiler ratings, you can compare boiler models side by side using our Head To Head tool.
You can compare the models from the brands in eleven categories such as warranty, efficiency, construction, availability, & 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!
