Hot-Link System

Hot Water Recirculation System

Taco technology saves thousands of gallons of water each year.
According to the Department of Energy, the average household wastes up to 12,000 gallons of water each year waiting for hot water. That’s energy, money and resources down the drain. We have the domestic hot water recirculation solutions that are right for the job, including our, Hot-Link ® System.

Instant hot water. No additional plumbing or electrical!
Hot-Link ® System is a quick, easy retrofit using the existing plumbing. Mount the by-pass valve under the sink and the pump at the water heater. The valve’s unique thermal disk technology sends cooled water back to the water heater so hot water lines remain hot.

Cleaning made easy.
There’s no need to remove the Hot-Link valve from the piping to keep it clean. Our exclusive clean-in-place design makes short work of keeping the system operating properly.
