Heliatos Beach Freeze Protected Solar Water Heater Kit

Our Beach Freeze Protected Solar Water Heating Kit allows you to install a solar hot water system you can operate year round in harsh marine environments. This kit includes MH-38 Panels and a Stainless Steel Heat Exchanger with a special food grade heat transfer fluid (DOWFROST) to create a separate freeze-protected loop. Filling your separate loop is easy with our Glycol Fill Valve. Please use our Glycol Calculator to determine the dilution ratio for winter conditions in your area as well as the total amount of glycol concentrate you need. As with all our systems, they connect directly to your existing water heater and don't interfere with an existing source of heat (gas or electric). This way you can enjoy hot water even during long cloudy periods. 

Each panel weighs 12 lbs. and is 24' by 24' but can still provide you with ample hot water. You can begin your system with a few panels and add more if you need more.  With this kit you DO NOT have to solder at all! Each kit comes with:
