HELIO-PAK: Closed loop heat-transfer appliance The Helio-Pak (HPAK) is an all-in-one heat-transfer assembly, specifically designed to simplify solar hot water systems and provide maximum heat transfer that is sixteen times faster than other heat transfer appliance on the market. The HPAK comes factory assembled and wired with all necessary components, making installation a trouble-free experience. Because the HPAK utilizes an external heat exchanger, it can often be adapted to the pre-existing hot water tank, reducing costs.
Standard Features:
•
Augmented heat exchanger surface promotes maximum heat generation
•
Superior heat transfer via unique counter-flow design
