Description
Frost Protection Valve for Caleffi Solar Hot Water 15mm | 603
The Caleffi Frost Protection Valve was used by various solar hot water manufacturers to meet the requirements of solar collector panels installed in a frost prone environment.
OPERATION
The anti-freeze safety device prevents ice build-up in domestic water circuits, thereby avoiding possible damage to water storages and pipes in solar systems. This device has been certified to Watermark to ATS 5200.012 The Caleffi 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 an element which reacts by opening the valve seat when the temperature drops. This allows warm water from the solar storage cylinder to flow through the solar collector panel and out of the valve. The warm water flowing through the solar collector makes it harder for the panel to spot freeze which could damage the solar collector. The warm water flowing through the valve will eventually close the valve seat and the water will stop fl owing. The Hitachi Valve will automatically repeat this cycle until the outside air temperatures rise.
MAINTENANCE
The frost protection valve has small water ways and may be prone to a build up of sludge when installed at the lower connection fitting of a solar collector. We recommend checking and cleaning at regular intervals to prevent valve malfunction and possible damage to the solar collector panel.

Replace every three years
I noticed water running off the roof recently, just during the night, and amounting to over 150L per day. Worked out it must be the Caleffi Anti-Freeze valve. I called the Solar hot water company and a tech rep confirmed that the valve is best replaced about every three years. Mine was letting water through even when the temperature was only 13 or 14 degrees celcius. It should not open until it is colder than 10 degrees. It hasn't been very cold since I installed the new one ( a simple job I did myself), but right now, at 10 degrees, there is no water running so I'm happy.
