This product is commonly specified as part of a fully electric heating and hot water system. When used alongside infrared heating, a Sunamp Thermino heat battery helps create a compact, low-maintenance solution for gas-free buildings. Our guide on Infrared Heating with Sunamp Thermino hot water systems explains how the full system works and who it is best suited for.
Considering a heat battery instead of a traditional hot water cylinder? The difference becomes clearer when you look beyond capacity alone. Heat batteries such as Sunamp Thermino store energy rather than water, which allows them to be more compact, reduce standing heat losses, and integrate more easily into electric-only buildings.
Sunamp Thermino heat batteries are particularly well suited to buildings that are designed around electricity rather than gas. This includes homes, flats, and commercial buildings where space, efficiency, and long-term reliability are priorities.
They are commonly specified in:
- Electric-only and low-carbon homes
- Flats and apartments with limited storage space
- Buildings using solar PV or off-peak electricity tariffs
- Projects replacing or avoiding traditional hot water cylinders
If you are deciding between a heat battery and a conventional cylinder, our guide Why Choose a Sunamp Thermino Heat Battery Instead of a Hot Water Cylinder? explains the key differences in more detail.
