ThermoPEX can provide you with a quick and easy, temporary, above ground installation any time of year, giving you time to decide the best possible location for your furnace without having to worry about frozen ground conditions or snow cover. The ThermoPEX System is an all-inclusive package with return and supply lines, insulation, and a protective waterproof (and temporarily weatherproof) jacket all in one pipe, and may be buried underground in the spring or summer when it's convenient for you.

If ThermoPEX is installed temporarily above ground, provisions should be made to prevent possible risk of fire coming into contact with the ThermoPEX. ThermoPEX is constructed of materials that can burn and transfer a fire. Do not cover the ThermoPEX with combustible materials like straw, hay or leaves.

A water jacket surrounds the furnace firebox and heat exchanger, and heated water is circulated to the home or building through insulated underground pipes -- an efficient way to move heat over distances. A Central Boiler outdoor furnace is designed to work with any existing heating system. Water-to-air or water-to-water heat exchangers or direct circulation conveys the heat into the structure's forced-air furnace, boiler or radiant floor heating system. This allows you normal thermostatic control. Central Boiler outdoor furnaces can provide heat for all your domestic hot water by adding a water-to-water heat exchanger, and you can save even more per month! Central Boiler outdoor furnaces also have the ability to heat multiple buildings, such as a garage, workshop, shed, greenhouse, or barn. It can even be used to heat a swimming pool or hot tub.

  • The Central Boiler outdoor furnace removes fire hazards from your home or building because all of the burning takes place outside.
  • An outdoor furnace won't affect your indoor air quality and can alleviate respiratory and allergy problems caused by indoor wood burning.
  • Eliminates mess from inside home that indoor burning creates
  • Thermostatic control allows you to heat your entire home with an even, steady heat.
  • Outdoor Wood Furnaces - Did you know that current Central Boiler outdoor wood furnace owners are using from 25 to 50% less wood compared to other wood heating alternatives? Since Central Boiler outdoor wood furnaces can burn larger pieces of wood they can dramatically reduce the time you spend preparing wood.

A wood heating system is the right choice for the increasing number of consumers who are concerned about our environment. Wood is a totally renewable resource, which, when burned, results in no net carbon dioxide increase and can help reduce your carbon footprint. On the other hand, fossil fuels, when burned, release carbon dioxide which otherwise would stay trapped in the earth. The burning of fossil fuels causes a net increase in carbon dioxide, which is believed to be responsible for the heat-trapping greenhouse effect. When heating with wood rather than fossil fuels, you actually achieve a net reduction in greenhouse gas emissions. In addition, harvesting firewood has a pruning effect on forests, which allows new growth to flourish. The wood you burn likely comes from your local area -- it's not imported and not subject to price increases due to events outside your control, as is the case with oil.
