Does my Mixergy cylinder have to be installed by a Mixergy Expert?

Mixergy cylinders can be installed by any plumber or heating engineer with the relevant qualifications. Of course, we highly recommend using one of our Mixergy Experts for their expert Mixergy knowledge!

What qualifications must my installer have to fit a Mixergy cylinder?

Installers must hold a BPEC G3 qualification to install an unvented hot water cylinder.

Are Mixergy cylinders installed differently from conventional hot water cylinders?

The installation of a Mixergy cylinder should be familiar to plumbers and heating engineers experienced with standard vented or unvented cylinder installations. Mixergy cylinders are designed with a plumbing footprint similar to that of conventional cylinders. There is a single inlet for the cold feed at the bottom of the cylinder and a single outlet for hot water at the top of the cylinder. The plumbing and electrical work is identical except for the added internet connectivity.

What wiring is required to install a Mixergy cylinder?

A Mixergy cylinder requires a mains voltage electrical supply. Mixergy cylinders must be connected to a dedicated 16A MCB-protected circuit via a 20A DP switch and be wired to the latest IEE wiring regulation. A qualified electrician is required to make an electrical connection to the unit.

Can I install a water softener with the Mixergy cylinder?

Mixergy recommends that water softeners be used in areas of hard water. Please note that the Mixergy warranty is invalidated for any installation in areas of >300ppm of calcium chloride. You can check the water hardness in your area by checking your local water supplier’s website.
