Pressure
Relief Valves Solar hot water systems can run much hotter than standard domestic hot
water systems. Hotter water expands more, and needs high quality pressure
relief valves to ensure the tank or other components do not burst under
pressure.
A qualified plumber can recommend the best practice solution for each
installation for pressure relief valves, including the number and placement of
them.
Air Relief
Valves Air locks can occur within the piping system (as well as the pump). These
can increase the pressure that the pump is working against, to the point
where the pump can no longer circulate the water.
To avoid this, an air relief valve should be fitted (especially in low pressure
systems).
Your registered plumber should install the air relief valve to the highest point
of the return from the solar water collector.
