Solar Panel Freeze Valve

The air temperature is monitored by a sensitive wax filled element which reacts by opening the fpv valve seat when the temperature drops.

Solar panel freeze valve.

The warm water flowing through the solar collector makes it harder for the panel to spot freeze which could damage the solar collector. This cycle will repeat as often as necessary to help prevent freezing. When properly installed this will allow warmer water supply to slush colder water from your solar panels.

The frost protection valve is designed to protect a solar collector panel from frost damage when the outside air temperature drops. The quality solar panel frost protection valves are made of brass and have been found to be the most reliable with a long service life. When temperatures approaching freezing approximately 34 f the valve will open. Also check the controller for correct settings and freeze turn on temp.

The solar freeze protection valve contains a thermal actuator. So what to do i. The frost protection valve is designed to protect a solar collector panel from frost damage when the outside air temperature drops. If you live in south florida or anywhere that doesn t have freezing conditions the answer is no.

Do we really need this anti freeze valve. The warm water flowing through the valve will eventually close the valve seat and the water will stop fl owing. When the temperature reaches 39 f the valve will close.
