1” ThermoPEX® is Central Boiler’s premium pre-insulated underground piping system, designed to efficiently transfer hot water between an outdoor furnace and your home, shop, garage or other building.

ThermoPEX comes fully assembled and ready to install, with two 1” oxygen-barrier PEX-A lines—one supply and one return—surrounded by high-density urethane insulation and protected by a thick, durable, waterproof polyethylene outer jacket.

Proper underground piping is critical to the performance of an outdoor wood furnace. ThermoPEX is designed to minimize underground heat loss, helping deliver more of your furnace’s heat to the building instead of losing it into the ground.

Don't Lose Your Heat Underground

Your outdoor furnace can only perform as well as the piping carrying its heat to the building. Poorly insulated underground lines can waste valuable energy and increase wood consumption.

ThermoPEX helps keep the heat where it belongs—inside the system and heading toward your home or building.

An excellent choice for Central Boiler outdoor wood furnace installations, replacement piping and new hydronic heating projects.
