Surecal 5 litre Expansion Tank

 

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. It comes pre-assembled and pressure set for easy installation. Mount on bulk head and use push fit plastic plumbing to install.

Fit the pre-assembled and easy to install potable water Surejust Expansion tank to your water system.

This will stop your water system from being under unnecessary stress, wasting water through the pressure release valve and provide a great deal of safety!

What is an expansion tank and why should i fit one?

An expansion tank is a safety device used in closed water heating systems such as a when a calorifier is used on a boat. It will absorb excess water pressure, which can be caused by thermal expansion as water is heated, or by water hammer

What size should I fit?

The expansion tank should measure 10% of the calorifier capacity. I.e. the 2 litre expansion tank would work with the 10-22litre calorifier, the 5 litre expansion tank with the 30- 55 litre calorifiers and the 8 litre with the 55-75 litre calorifiers.

Where should I fit one?

It should be fitted after the thermostatic mixer valve on the calorifier but before the first outlet. It comes pre assembled with a connection ready to push straight into a plastic plumbing tee piece.

What does it come with?

It comes pressurised to go with a surecal calorifier (this can be altered) a bracket for mounting, a st/steel strap and a connection ready to go straight into plastic plumbing for an easy installation.

What pressure should it is set to?

Our tanks come pre pressurised to go with the calorifier. If you need to change this then it should be set to a pressure above your pump pressure but below the pressure release valve cut out pressure. This is very important or the expansion tank wont work properly.
