The key to effortless transition
Our Thermino ePlus and xPlus range of batteries come fitted with our Optimino controller, which allows the heat battery to work with different energy sources by using a compatible Optimino key. The key makes it easier and more affordable to transition to renewable energy by allowing upgrades to heating systems without the added expense of replacing the thermal storage component – Thermino ePlus or xPlus.
Designed to future-proof the investment in Thermino heat batteries, homeowners and landlords can make the switch from fossil fuels to renewables at their own pace and budget.
Make the ecofriendly choice
To replace hot water cylinders with a more eco-friendly option, choose between Thermino ePlus, a replacement for direct hot water cylinders, or Thermino xPlus, depending on whether you have a heat pump system or not. As a replacement indirect hot water cylinder, the Thermino xPlus can also be charged by a boiler, spreading the cost of transitioning to renewables further. Start with good thermal storage and build from there.
