The Electric Heating Company (EHC) is adding the Mixergy X smart hot water cylinder to its product range and will sell it through the EHC website, under a partnership announced by Mixergy on 30 October 20241. Mixergy described the deal as delivering "innovative electric heating and hot water solutions" and said the cylinder would be offered as a Mixergy-branded product combining EHC's electric heating expertise with Mixergy's cylinder technology1.
Mixergy lists the following features for the Mixergy X range1:
| Feature | Claim |
|---|---|
| Top-down heating | Heats only the required amount of water, saving energy and reducing bills |
| Smart control | App control, intelligent scheduling, machine learning, integration with smart tariffs |
| Rapid heating | Hot water up to 10 times faster than conventional cylinders |
| Energy efficiency | Saves up to 21% on hot water gas consumption |
| Compatibility | Solar PV and heat pumps, including retrofitting at a later date |
| Grid support | Demand-side response at times of high electricity generation |
| Warranty | 25 years |
The 21% saving figure is given by Mixergy as a reduction in hot water gas consumption, not electricity, and no running-cost figures for the cylinder in a UK home are given in the announcement1. The claim that the cylinder heats water up to 10 times faster than conventional cylinders is also Mixergy's own1. No prices, cylinder sizes or delivery dates appear in the announcement1.
David Barrett, chief executive of EHC, said:
"The Mixergy cylinder range offers a smart solution working in conjunction with the EHC electric boiler range. This collaboration aligns perfectly with our mission to provide efficient, sustainable heating and hot water solutions that meet the evolving needs of modern homes."
Andrew Keating, chief commercial officer of Mixergy, said partnerships between industry stakeholders were "vital for a successful energy transition" and that specifiers, installers and homeowners were starting to think about preparing for a shift towards electric domestic heating and hot water1.
Why it matters for households
Hot water is one of the few remaining household loads that gas still serves in most UK homes, so a cylinder designed to work with an electric boiler, solar PV and a heat pump is a route to taking that load off gas without changing the whole heating system at once. The Mixergy X is described as compatible with solar PV and heat pumps and as able to be retrofitted to those sources later, which matters for a household that cannot afford to change everything in one go1. Top-down heating, which warms only the water needed rather than the whole cylinder, is the mechanism Mixergy gives for the savings, and the app's ability to work with smart tariffs is the mechanism for shifting when the cylinder draws power1. Demand-side response, listed as a feature, means the cylinder can in principle absorb electricity at times of high generation, which is a grid benefit rather than a direct household one1. The 25-year warranty is the longest-lived claim in the announcement and is relevant to anyone weighing a cylinder against a combi boiler, though the announcement gives no installed cost, no cylinder capacity and no independent test data1. Households comparing options may find the site's pages on Mixergy smart hot water cylinders and on electric heating running costs useful background, and the wider emerging technology section covers the category this product sits in.
What happens next
The announcement gives no date for when the Mixergy X will appear on the EHC website, no pricing and no list of cylinder sizes1. No further steps, trials or installation arrangements are set out in it1.
