6 Frequently Asked Questions about “How to protect solar collectors from freezing”

Do solar collectors need to be winterized?

In climates where the pool is shut down for the winter, there are no special requirements for winterizing solar collectors as long as the collectors and piping have been installed to allow the system to completely drain each time the pump cycles off.

Which solar water heating system is most vulnerable to freeze damage?

Solar water heating systems that use only water as a heat-transfer fluid are the most vulnerable to freeze damage. "Draindown" or "drainback" systems typically use a controller to drain the collector loop automatically.

How can I bypass the solar filtering system?

To bypass the solar filtering system, switch the solar control to the bypass position. Then, turn the circulating system off and allow the solar collectors and piping to drain. Isolate collectors with a gate or ball valve in the collector feed line and a check valve in the collector return line.

Do solar collectors work in the summer?

Many people believe that solar collectors only work in the summer, however this type of free energy is available throughout the year. From May to September, solar thermal could produce 100% of the energy required for heating your domestic water.

How do I drain my solar pool heater system?

To drain your solar pool heater system, first turn the circulating system off and allow at least 30 minutes for the solar collectors and piping to drain. If your installation does not allow for gravity drainage, the system must be manually drained. Once drained, close the isolation valve in the collector feed line.

Do solar water heating systems need antifreeze?

Solar water heating systems that use an antifreeze solution (always propylene glycol, never or ethylene glycol because of toxicity) as a heat-transfer fluid have effective freeze protection as long as the proper antifreeze concentration is maintained. Antifreeze fluids degrade over time and normally should be changed every 3–5 years.
