HotLine Internal Pipe Heater
Energy-efficient furnace drains can freeze.

Problem: Homeowners in areas with freezing temperatures may suffer frozen sewer line backups due to condensation buildup from their energy-efficient furnace drain into the sewer line.

Wrapping the line with heat tape requires expensive excavation and repair, and isn’t a permanent fix.

Solution: To easily prevent frozen furnace drains, HotLine Internal Sewer Pipe Heaters install inside the pipe through a Y-fitting cleanout above the floor. Inside- the-pipe installation avoids costly excavation, pipe-wrapping, and rebuilding of basement floors and floor drains.

HotLine’s transformer operates on a 120 Volt, 15 Amp circuit. The transformer provides energy efficient, NEC compliant, low voltage output to HotLine’s heating element.

The heating element’s low operating temperature makes it safe for PVC, copper, ductile iron, steel, cast iron, polypropylene, and polyethylene pipe. HotLine’s low voltage also ensures there is no danger of electric shock. HotLine’s UL-approved parts provide decades of trouble-free service.

Result: “We have a winter vacation home in ‘the icebox of the US’. Our energy- efficient furnace kept freezing up the sewer and making a big mess. We installed a HotLine and have been trouble-free ever since.”, reports Helen M. of Fraser, CO.

HotLine’s Internal Pipe Heaters work for both water and sewer lines as well as commercial applications from animal waterers to pipelines to cooling towers, sump pumps, and refrigeration condensation lines.

HotLine is food-safe and CE approved.
