Solar Hot Water Panel Freeze Protection Valve Black Plastic

When properly installed this will allow warmer water supply to slush colder water from your solar panels.

Solar hot water panel freeze protection valve black plastic.

Water is coming out on to the roof from what i believe is the freeze protection valve. Unfortunately the local plumber has failed to fix any problems and has only given large bills. That is besides the point now i am trying to fix it. A freeze protection valve is a mechanical device that opens at 35ºf and closes at 40ºf allowing water to flow through the piping to keep it from freezing.

Keep your solar collectors and exposed pipes from freezing with the vernatherm solar freeze protection valve the vernatherm valve contains a thermal actuator that opens the valve when the temperature approaches freezing and re closes it upon warm up. This cycle will repeat as often as necessary to help prevent freezing. Such systems should have copper bronze brass stainless steel plastic rubber components in the plumbing loop and plastic or glass lined storage tanks. When the warmer water reaches the valve the port closes and water discharge stops.

Active closed loop is the final type of solar water heating system on my list fig. The solar freeze protection valve contains a thermal actuator. The valve operates without any electrical power. Solar water heating systems which use liquids as heat transfer fluids need protection from freezing in climates where temperatures fall below 42ºf 6ºc.

Install a freeze protection valve. When temperatures approaching freezing approximately 34 f the valve will open. In cases where freezing is a constant concern you might consider a freeze protection valve. This method of freeze protection activates a pump to circulate a little bit of hot water from the storage tank back into panels when low ambient temperatures are experienced.

Another type of solar water heating system is re circulation. The photovoltaic solar panels or pv solar panels convert the sun s energy into electricity which then can be used to heat water. We are set up with a solar water heating system here in new zealand. Solar panels can also directly heat water by heating water filled pipes within the solar panels or by heating a transfer fluid such as antifreeze usually propylene glycol.

Options 1 4 will take care of 95 of our customers. The frost protection valve is designed to protect a solar collector panel from frost damage when the outside air temperature drops. Our freeze protection products are classified as thermal valves these valves sense ambient temperature when temps reach 35f the valve opens and purges fluid.
