Expansion Tanks

Expansion Tanks are an essential feature on any hot water system. They need to be installed on the hot water supply after the hot water heater. Anywhere on the hot side of the system, but preferably as near to the hot water heater as is reasonably possible. It can be fitted in any orientation.

The tanks are pre set at our factory for most systems, however the pressure is worth checking as some installations are set up with different pump pressures. In general the required pressure setting for an expansion bottle is 5psi above your pump pressure. If you do not know your pump pressure then set the expansion tank to 30 psi.

Surejust accumulator and expansion tanks are supplied complete with mounting bracket and plumbing fitting, ready to connect into your system.
