Wisewater Side Arm Heat Exchangers have a compact, lightweight design that allows for a quick and easy installation. Designed with natural thermosiphon heating technology, this heat exchanger is enhanced with fins to allow for higher heat transfer efficiency and to help reduce cross-contamination for potable water. This fin-enhanced design, which is 5-8 times bigger than the traditional bare tube design, produces both significant turbulence on the system side and faster heating at a greater capacity. This type of heat exchanger is recommended for smaller households of about 1-3 people or households with lower hot water usage.

FAQ and Support
Thermosiphon is a method of heat exchange through convection. By using convection, water from your hot water heater can be drawn up through your heat exchanger without the use of mechanical pumps.

33" works with 40gal. water heaters.
38" works with 60gal. water heaters.
38" Double Wall works with 40gal. water heaters.
The difference between single wall and double wall models is that the second wall helps prevent contamination in the water if a leak should happen. These heat exchangers are recommended for households of 1-3 people or households that don't use as much hot water.
