If you're looking for an outdoor wood boiler that can provide you with consistent heat all winter long, there are a few different types to consider. The most popular type of outdoor wood boiler is the barrel heater.
These units are made out of a large barrel-like container filled with hot coals or briquettes. An exhaust pipe exits the top of the barrel, and the heat from the burning fuel is used to create heat inside the barrel. As the barrel gets hotter, the heat travels up the pipe and into your home. You can easily get the best wood boilers online.
Because these boilers use real fire, they require special permits in some areas. If you're interested in using one of these boilers, be sure to check with your local authorities first.
Another popular type of outdoor wood boiler is the log burner. These units are made from a large stack of logs that have been cut into sections equal in size.
The logs are arranged around a central firebox, and as the logs get hot, they start to burn more quickly and produce more heat. Because these burn hotter than barrel or log burners, they require less fuel to produce the same amount of heat, making them more cost-effective over time.
