The Apricus Solar Conversion Valve (SCV) is a special brass valve designed to allow existing hot water tanks to be retrofitted into solar storage tanks, thus eliminting the need to purchase an additional tank.

The valve simply fits into the bottom inlet/drain port of the tank and allows To Solar, Solar Return as well as retaining the orginal function of the port (cold in or drain). The valves are available in both 3/4"M BSP and 3/4"M NPT threads to allow compatibility with most tanks.

The copper return pipe ensures delivery of hot water at a higher level than the cold out, thus preventing disruption of stratification layers. This also ensures that the coldest water is always delivered to the solar collector for heating, thus maximising solar conversion efficiency.
