MIXERGY 180L UNVENTED INDIRECT CYLINDER

The Mixergy 180L Unvented Indirect Cylinder is a smart, mains-pressure hot water tank designed for efficient, flexible hot water delivery in modern homes. Using an indirect heating coil to connect to a boiler or heat pump, it also supports electric top-up via its immersion heater. Mixergy’s smart control heats only the volume of water you need, cutting energy use and speeding up heat-up times.

With app-based controls, scheduling, and energy insights, you can optimise hot water for off-peak tariffs and self-consume excess solar PV. The system supports remote boosts, legionella protection cycles, and integration with home energy setups, helping lower running costs while maintaining comfort.

Built from high-grade stainless steel with thick insulation, the 180L model provides reliable, mains-pressure performance suitable for medium-sized households. As an unvented cylinder, it must be installed and commissioned by a qualified G3 engineer in accordance with Building Regulations.
