Our Freeze Protected Solar Water Heating Kit allows you to install a solar hot water system you can operate year round. This kit includes SW-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 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:

Your selected quantity of SW-38 Panels
1 Grade A 25W PV panel to power the pumps - NO grid connection required - plus wire and PV mounting kit
1 Heliatos HS-21 Pump for the Glycol Side
1 TopsFlo TD5 Stainless Steel Pump for the Water Side
