Tankless water heaters with DuPont input

01 August 2015

Seisco International is introducing the next generation Supercharger tankless water heater unit, which uses DuPont engineering polymers in several components.  The units can help homeowners meet the US’ National Appliance Energy Conservation Act (NAECA) requirements, which were updated in April.

The new standards, according to Seisco president David Seitz, could drive up the cost and size of tank-type water heaters because efficiency technology will have to be added to tanks that are 55-gallon or larger. “A Seisco Supercharger coupled with a 40-gallon tank matches the performance of a 60- to 80-gallon tank with significantly lower energy use because you heat less water all day,” he said.

The unit, at 15 inches by 7 inches by 6 inches, is small enough to be placed near the use point.

“Thousands of gallons of water are wasted each year waiting for hot water to travel through cold pipes,” he said. “Heating at the use point can significantly reduce water waste and save energy.” 

The new tankless water heaters feature an internal heating chamber, which is injection moulded of DuPont Zytel nylon for high heat resistance, thermal stability and compliance with NSF and UL requirements. DuPont Crastin PBT thermoplastic polyester delivers impact resistance and compliance with UL flammability requirements in a one-piece protective exterior housing.

A microprocessor control manages on/off when flow starts/stops. The water heater’s patented mixing chamber provides a small amount of heated water and the patented “Power-Sharing” technology helps ensure elements heat evenly. These innovations help protect against scalding, scaling and sediment build-up.

The single-chamber Seisco models can be used as a back-up for both new and existing hot water storage tanks in single-family homes. Multifamily water heaters allow building owners to eliminate storage tanks in each unit.
