Mixergy announced an updated heat pump interface on 24 November 2023. The product, the Mixergy Heat Pump Interface v2, is a revision of the company's existing interface between its hot water cylinders and heat pumps1.
The company said the update delivers better integration between cylinder and heat pump and simplifies installation where an existing heat pump is already in place. The interface now uses the heat pump's own thermal probe rather than requiring a separate one, which Mixergy describes as simplifying the installation process1.
"Our latest update has been to our heat pump interface, the Mixergy Heat Pump Interface v2."
Mixergy said the change builds on its existing heat transfer module and adds what it calls a seamless control interaction mechanism, intended to ensure the best possible performance1. The company framed the update as part of wider work on decarbonising homes1.
No pricing, availability date, compatibility list or efficiency figures for the Heat Pump Interface v2 have been reported1. The announcement does not state which heat pump models or cylinder ranges the interface works with, or whether existing users can upgrade. Mixergy directs readers to its technical support site for the heat pump integration module, guides, troubleshooting and FAQs1.
Why it matters for households
A hot water cylinder and a heat pump have to work together: the heat pump produces the heat, the cylinder stores it, and the controls decide when the heat pump runs and how hot the water gets. Poor coordination between the two can mean the heat pump runs when it is least efficient, or that hot water runs out sooner than expected.
For a household, the practical point of an interface like this is how much of that coordination is handled by the cylinder's own controls rather than by extra wiring and sensors. Mixergy says the v2 uses the heat pump's existing thermal probe, which reduces the number of components an installer has to fit1. Fewer added parts can mean less time on site, though no installation time or cost figures have been published1.
For homes already heated by a heat pump, an interface that works with the existing probe may matter where the original installation did not include cylinder-side controls. For homes still on a gas boiler, the relevance depends on whether a heat pump is fitted later. Mixergy has not said whether the v2 changes how a cylinder performs once installed, only that it improves integration and simplifies installation1.
