Insulated PVC

Over the years the outdoor woodburning furnace has proven to be a safe, economical and versatile means of providing heat. Through the latest in design and engineering, manufacturers continue to increase the efficiency of these units. Whether for forced air, in floor radiant, or other systems, these furnaces are very adaptable and efficient.

Insul-Seal is proud to be a component that increases the efficiency of the outdoor furnace installation. Insul-Seal also helps keep the heating plant and distance away from the house tor other building to be heated. This separation eliminated the wood mess sometimes associated with indoor woodburning units. By distancing the combustion unit from the hose, the safety concerns associated with wood burning units are also removed. This makes this type of heat well received by insurance companies.

By using Insul-Seal insulated PVC pipe as a conduit for the hot water and return lines to and from the furnace, heat loss between the furnace and the heat exchangers at the areas to be heated has been virtually eliminated.

On a typical 80'-100' run between furnace and house water temp can be within 3º of the furnace temp as it enters the heat exchanger at the house.

This translates into less wood to be burned, and less times to load the furnace. An already efficient heat source is made even more economical.
