Heliodyne 
The Helio-Pak (HPAK) is an all-in-one heat-transfer appliance assembly,
specifically designed to simplify solar hot water systems and
provide maximum heat transfer. The HPAK comes factory
assembled and wired with all necessary components, making
installation a trouble-free experience. A major benefit the Helio-Pak provides is that it attaches
directly onto the hot water tank. As a result, under certain
conditions, the HPAK can be mounted onto a pre-existing
water tank, thereby reducing costs. This is a feature no other
solar hot water heat-exchanger on the market can offer.
Note: This appliance cannot be used with existing gas or propane heaters, unless they have an electrical ignition! If the gas heater has an electric ignition, then the Helio-Pak PRO appliance can be used.
Features
• Augmented heat exchanger surface promotes maximum heat generation
• Superior heat transfer via unique counterflow design
• No new tank needed; mounts to existing tank
• “Plug & Play” installation
• Viewable heat exchanger leak detection
• Several sizes available for differing loads
The Helio-Pak comes assembled with:
• Double-wall external heat exchanger with leak detection
