Central Boiler manufacturers the Maxim outdoor wood pellet furnace. The Maxim outdoor wood pellet furnace can heat an entire home, multiple buildings along with domestic water. The Maxim doesn't take up valuable living space like indoor wood pellet stoves and is able to heat for days on a single fuel load. It is also efficient, saves as much as 75% on your heating costs and reduces your dependence on foreign oil by heating with renewable energy.
