MIXERGY 150L SMART UNVENTED DIRECT

The Mixergy 150L Smart Unvented Direct is a mains-pressure electric hot water cylinder designed to deliver fast, efficient hot water while using less energy. Its smart control system heats only the volume you need, giving you quick hot water recovery and powerful showers without running a boiler.

This direct model uses built-in electric immersion heating with top-down heating logic for rapid availability of hot water. The unvented design provides balanced, high flow rates to multiple outlets, making it suitable for modern homes with mains cold water supplies.

Smart controls let you schedule heating, set target levels, boost on demand, and monitor usage from the Mixergy app. The system can learn your routine to pre-heat efficiently and can take advantage of time-of-use electricity tariffs. When installed with suitable equipment, it can also store excess Solar PV generation as hot water.

Constructed with a premium stainless steel cylinder and high-performance factory-applied insulation, the unit minimises standing heat loss. Integrated sensors and safety functionality include temperature control and automatic anti-legionella pasteurisation cycles.

Installation must be carried out by a competent G3-qualified installer. An electrical supply is required for the immersion heaters and controls, and an internet connection is needed to enable smart features.
