Solar Hot Water Panel Freeze Protection Valve Black Plastic

That is besides the point now i am trying to fix it.

Solar hot water panel freeze protection valve black plastic.

Solar water heating systems which use liquids as heat transfer fluids need protection from freezing in climates where temperatures fall below 42ºf 6ºc. Our freeze protection products are classified as thermal valves these valves sense ambient temperature when temps reach 35f the valve opens and purges fluid. Install a freeze protection valve. 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.

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. The solar freeze protection valve contains a thermal actuator. Such systems should have copper bronze brass stainless steel plastic rubber components in the plumbing loop and plastic or glass lined storage tanks. 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.

Unfortunately the local plumber has failed to fix any problems and has only given large bills. Another type of solar water heating system is re circulation. Typically in solar applications the valve port opens on descending temperatures allowing the near freezing water in the solar panel to be discharged and replaced with warmer supply water. The frost protection valve is designed to protect a solar collector panel from frost damage when the outside air temperature drops.

The air temperature is monitored by a sensitive wax filled element which reacts by opening the fpv valve seat when the temperature drops. Many direct solar thermal systems use these devices. Options 1 4 will take care of 95 of our customers. In cases where freezing is a constant concern you might consider a freeze protection valve.

This cycle will repeat as often as necessary to help prevent freezing. Water is coming out on to the roof from what i believe is the freeze protection valve. When the warmer water reaches the valve the port closes and water discharge stops. We are set up with a solar water heating system here in new zealand.

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. 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.
