Water Furnace

Sevens member Bob Brown explains how advances in plastic pipes have aided geothermal heating and cooling.

Robert R. Brown, director of product development and marketing for WaterFurnace, says other technological improvements have propelled geothermal growth.

“What’s really changed, too, is plastic pipe,” he says. “It’s all thermally fused – the joints are fused plastic, so there are no glues and no clamps, and they don’t leak.” He calls the newer piping “very reliable” and maintenance-free, and says the life expectancy of the pipe “is about 200 years.”
