MIXERGY 210L SMART UNVENTED DIRECT SLIM

The Mixergy 210L Smart Unvented Direct Slim is a connected, mains-pressure hot water cylinder designed for homes using electric heating. Its slimline form factor helps it fit into tighter airing cupboards while delivering a generous 210-litre capacity for everyday family use.

This direct model uses built-in electric immersion heating with smart controls to heat only the volume of water you need. You can set a target percentage, schedule heat times, and boost on demand via the Mixergy app, helping to reduce energy consumption and improve comfort. The cylinder’s stratified heating enables quick top-ups, so you get hot water fast without heating the entire tank.

It is designed to work with time-of-use electricity tariffs and can capture low-cost or low-carbon energy when configured appropriately. It can also interface with solar PV surplus using compatible accessories or integrations, making it a strong option for households looking to decarbonize hot water.

As an unvented cylinder, it delivers strong flow at mains pressure and includes the usual safety and control components required for unvented systems. High-performance factory-applied insulation helps minimize standing heat losses. Installation and commissioning should be carried out by a qualified unvented (G3) engineer.
