The popularity of a heater that does not use electricity is what drives our business. Heating wood fired hot tubs, plastic spas and pools using thermosiphon provides a NO noise ultimate zen experience. Our thermosiphon kits quickly adapt to any hot tub or pool by inserting two wall ports into the tub/pool.

High temperature silicone coupler and high temperature CPVC 1 ½" are connected using stainless steel clamps. Ideal for up to 4 feet away from the tub. NOTE: regular PVC or ABS pipe should never be used as it is not rated for high temperatures and will melt.

Includes:
• 6' of 1.5" CPVC pipe
• 2x silicone couplers
• 2x silicone elbows
• 2x wall fittings
• 2x 1.5" gate valves
• 8x stainless steel clamps
