Use main cold-water supply and not a header tank

Mixergy cylinder tank

Mixergy tanks can be used with a number of different heat sources.  It is important to confirm with us how you plan to heat your water, so we can quote you the correct product:

Gas or oil boiler – you will need an indirect tank if you are connecting to a conventional gas or oil heater.

Electric immersion heater – a direct tank will be needed if you plan to use an immersion heater to heat up your water.

Heat Pump – a direct tank will be required for this system.  Please note an additional plate heat exchanger heat.

Solar Thermal – the tank will be supplied with a solar thermal coil which will operate with a conventional boiler or immersion heater.

Solar PV – if you wish to use electricity generated from solar PV panels to heat your water alongside the main heat source, you will need to purchase a separate solar PV kit along with the tank.

Mixergy hot water tanks offer a highly energy-efficient and cost-effective way to heat water in the home. They are internet-connected and can be operated by an app on your phone or tablet.
