Smart commercial hot water cylinders
Mixergy’s commercial hot water cylinders know exactly how much hot water they hold and heat only what the building needs, so you can cut running costs, electrify hot water without oversizing the system and decarbonise hot water as part of your building’s decarbonisation strategy.
Hot water for real building demand
Smart commercial cylinders that cut running costs and keep up at peak times
Lower running costs
Only heat the water you’ll use, saving up to 40% on hot water energy.
No more oversizing
Precision sensing shows how much hot water you have, so you size to real demand.
Ready for peak demand
Usable hot water within 35 minutes and up to 10 times quicker reheat.
Legionella control built in
Automated full-cylinder pasteurisation, with a data record of every cycle.
Works with the heat source
Runs on direct electric, heat pumps, VRF, or solar PV.
Best in class Demand Side Response (DSR) capability
Generate recurring revenue at larger sites by capturing DSR value.

Commercial hot water cylinders made smart
Whether you’re replacing or designing a new system, every Mixergy commercial cylinder is configured around the site’s demand and the heat sources your need today, or tomorrow.
It senses.
It learns.
It heats at the right time.
It records.
It cleanses.

Hot water system design, as a CPD session for your team
We’ve developed a CPD session on designing stored hot water for commercial buildings, covering sizing to measured demand, Legionella control and the move from gas to electric hot water. Book in your free session today.
Proven in demanding buildings
Hampton Court Palace
A trial with Historic Royal Palaces at a site that welcomes over 500,000 visitors a year, heating only the water that’s needed while working within the palace’s conservation requirements.
“If we can achieve significant carbon reductions at a site as complex as Hampton Court Palace, we can prove it’s possible for historic buildings across the UK.” Jen Stone, Head of Sustainability, Historic Royal Palaces

This isn’t just about replacing cylinders. It’s about rethinking where energy comes from, how we use it, and what that means for commercial electrification. This is how the path to net zero begins.
