Heliatos Boat Freeze Protected Solar Water Heater Kit with External Heat Exchanger
This kit contains everything you need to add a high quality solar water heater to your boat. If your boat water heater does not have a built-in heat exchanger but you still want to install a freeze protected (closed loop) system this kit is for you. Included is a compact stainless steel heat exchanger (316 alloy) and all other parts required for a closed loop system. The antifreeze in the solar loop is heated by Heliatos MH-38 solar water heating panel. This panel has unbreakable twinwall polycarbonate glazing that can withstand hail and other debris. Its strong aluminum frame makes it tough yet lightweight, only weighing 12 lbs.
The MH-38 panels include special features to prevent corrosion even in the harshest marine environments:
- Powder-coated frame and backing, gives the appearance of white enamel
- Zinc-phosphate internal corrosion protection
- Sealed construction
- Stainless steel hardware
These panels have unbreakable twinwall polycarbonate glazing, and a strong aluminum frame, yet only weighs 12 lbs.

Maintenance Tips
-
Flush the System Annually:
- Flush the system annually to remove mineral buildup, sediment, or marine debris from the heat exchanger and pipes. This helps maintain performance and prevents blockages.
-
Check for Leaks:
- Inspect all seals, connections, and fittings for leaks. Tighten any loose fittings or replace worn seals to avoid water loss and ensure the system operates efficiently.
-
Prevent Blockages:
- Check the intake, outflow areas, and external heat exchanger for any blockages, such as marine growth, sand, or debris. Clean thoroughly to ensure proper water flow and heat transfer.
-
Ensure Proper Drainage:
- Ensure the system has proper drainage to prevent water from freezing in the pipes, especially in cold climates. Drain the system if necessary when the boat is not in use for extended periods.
-
Winterize the System:
- Before winter storage or exposure to freezing temperatures, properly winterize the system by draining the pipes and checking the freeze protection fluid levels. This will prevent freezing and damage to the system.
-
Inspect External Heat Exchanger:
- Regularly inspect the external heat exchanger for wear, corrosion, or damage. Clean the heat exchanger to maintain its efficiency in transferring heat from the solar panels to the water.
-
Routine Performance Check:
- Periodically check the overall system performance, ensuring the water flow is consistent and the heat exchanger is functioning properly. If the system is underperforming, inspect the heat exchanger for blockages or damage.
