I’ve just had my second service on my heat pump, which means I’m now going into year 3 since having it installed and having a gas free house. Facebook groups for heat pumps were full of people complaining about the cost to run these systems, the noise the units make, how the houses were cold etc - this has just not been my experience at all. I have had a comfortable & evenly heated property for 3yrs, my running costs are slightly less than my previous gas system, the unit is as quiet as a mouse even on really quite cold nights….. Why is this? Because Clean Heat Solutions know their stuff. The design of the system was spot on, bespoke to my property. I only have good things to say about the team, each service has been thorough, and I’m confident that having shopped around lots of companies over 3yrs ago - that I absolutely made the right choice.Google

A MORE EFFICIENT WAY TO HEAT YOUR WATER

A MORE EFFICIENT WAY TO HEAT YOUR WATER

Mixergy take a fresh approach to hot water in their mission to decarbonise the home and wider energy networks.

The Mixergy tank is a premium stainless steel cylinder designed to optimise energy consumption, improve utilisation of renewable energies and enable intelligent control over water usage. Their cylinders, which can be configured as open-vented or pressurised, can heat with all conventional and renewable heat sources. Internet connectivity means the Mixergy tank is primed for users to benefit from dynamic Time of Use tariffs.

  • Built-in machine learning studies your household's hot water habits over time, automatically refining heating schedules so you always have hot water ready when you need it — without heating a drop more than necessary.
  • Compatible with solar PV, heat pumps, and hydrogen-ready boilers, the Mixergy tank is designed for the future of home energy — making it a natural fit alongside the renewable heating systems we install across West Sussex and Hampshire.

HOW DO MIXERGY TANKS WORK?

HOW DO MIXERGY TANKS WORK?

Conventional hot water tanks heat all or nothing irrespective of how much hot water is required by the user. This can waste energy heating water that isn’t required and can result in unnecessarily long heating times.

The Mixergy tank differs to conventional tanks in three fundamental ways:

  • Novel top-up technology enables you to selectively heat by volume, rather than time
  • Temperature sensors make sterilisation cycles and hot water volumes measurable
  • Internet connectivity and the Mixergy App provides smart remote control

SAVE 5-20% ON HOT WATER BILLS

Mixergy’s top-up technology exploits thermal stratification (water rising when it heats) to ‘float’ hot water on top of cold to enable users to selectively heat different volumes of water. When the tank charges (heats), it increases the portion of water which is heated from the top down, rather than trying to heat the entire volume at once, as conventional cylinders do.

By only heating what you need you can save 5-20% on hot water bills through energy savings.

HOT WATER READY 5X FASTER

Top-up technology also enables Mixergy to deliver usable hot water up to 5x faster for direct electric tanks, and up to 2x fasterfor indirect gas tanks. By heating smaller volumes of water as you need it, hot water is ready faster.

SAVE 5-20% ON HOT WATER BILLS
30% more hot water = install smaller

30% more hot water = install smaller

In conventional hot water cylinders, your hot water is diluted by the cold water that enters the tank whilst you ‘draw off‘ your hot water. Mixergy uses novel diffusers that prevent the cold water from stirring up your hot water. In practice this means a Mixergy cylinder retains 30% more usable hot water when compared side-by-side to a conventional hot water cylinder (National Physical Laboratory accredited).

The ability to hold 30% more usable hot water means you can install a smaller cylinder, making more room available in your airing cupboard.

SMART HOT WATER CONTROL

Each Mixergy tank has an onboard smart controller that connects the tank to the internet. This allows you to control your Mixergy tank via the Mixergy app. You can: Boost instantaneously, set schedules, track your consumption and costs, change your energy sources and much more!

Each Mixergy tank also comes with a handheld controller that allows you to locally check how much water you have available and boost there and then. Mixergy affectionately call this controller ‘The Gauge’.

SMART HOT WATER CONTROL
Lower gas consumption by up to 21%

Lower gas consumption by up to 21%

Fitting a Mixergy cylinder could typically reduce the amount of gas used to provide hot water by 12%, compared to fitting a new market leading alternative cylinder.

If a boiler is short cycling regularly, fitting a Mixergy cylinder can help to eradicate this, leading to total water heating gas savings of up to 21%.

These savings have been independently verified by the Energy Savings Trust.

The initial calculations and quote were done by Aaron (using Heat Geeks software) and everything was explained clearly. The heat pump and hot water cylinder etc were fitted and plumbed in by Rob and James. The electrical work was then carried out by Fraser. All 3 worked hard with minimal disruption and completed the work within the time quoted. Then Aaron did the commissioning and handover, explaining everything well. It's early days but everything is working as expected and I'm confident that if any niggles arise they will be sorted quickly and efficiently.
