The key to effortless transition
Future-proof hot water with a multi-technology route to net zero.
The Optimino technology 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.
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—you can add solar PV to the ePlus model, and a solar PV and heat pump to the xPlus model later without the need to change the heat battery.
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.
That enables compatibility with multiple energy sources: Optimino enables Thermino to work across common pathways like grid electricity, solar PV, boilers and heat pumps, so your hot water component stays in place as the rest of the system evolves.
You can start with what you have today, then add low-carbon technologies when timing and budgets allow. It is a step by step route that supports long-term decarbonisation and keeps you moving towards net zero.

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 of 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.
The Optimino technology enables this by keeping Thermino compatible as you introduce new technologies. So you can improve performance now, then add renewables later, without the need to replace the thermal store.
How Optimino adds flexibility
Thermino ePlus
Find out more about Thermino ePlus
A compact heat battery that can be powered by grid. Add solar PV when you are ready using the Optimino PV key, so you can capture surplus PV electricity for hot water without replacing the heat battery.
Thermino xPlus
Find out more about Thermino xPlus
A compact thermal store that can work with boilers, solar PV and heat pumps using the correct Optimino key. Ideal if you want to start with a boiler today and move to heat pumps as part of a your net zero retrofit journey.
