Regular price $ 39.95

Keep your solar collectors and exposed pipes from freezing with a SmartTechProducts Solar Freeze Protection Valve. The valve operates without any electrical power. The Solar Freeze protection Valve contains a thermal actuator. When temperatures approaching freezing, approximately 34°F, the valve will open. When properly installed this will allow warmer water supply to slush colder water from your solar panels. When the temperature reaches 39°F the valve will close. This cycle will continue preventing panels and pipes from freezing.
