Pressure Temperature
Relief Valve (PTR) /
Expansion Control Valve
(ECV) where applicable.
An 850kPa and 99°C PTR valve is used on the Solargain water tank,
which is located on the side of the water tank and is essential for its safe
operation. The PTR valve is designed to allow 3-5% of total tank volume
to discharge during heating to allow for hot water expansion.
Water pressure is slightly
lower than previous hot
water system
Pressure Reduction Valve
(PRV)
A pressure reduction valve has been installed to limit the inlet pressure
to your new Solargain Water Heater. This device regulates the incoming
pressure & increases life of the cylinder. This device will also protect your
cylinder if the mains pressure is increased by the local water authority.
