Hi

We heat our 1980 chalet bungalow in Shropshire with a tepeo ZEB heat battery and a mix of UFH and radiators.

The ZEB is a dry-core heat battery, that consumes electricity when it is cheap, and stores it as heat. That heat is then delivered to the hydronic heating system when called for by a thermostat, in our case a Honeywell Evohome that modulates the ZEB using OpenTherm. As we have a time-of-use electricity tariff that means that the heat we use at 6pm in the evening cost 7p/kWh from the off-peak period, rather than 27.8p/kWh from the peak period, equivalent running costs to a CoP of ~3.9.

We also have a Sunamp Thermino, controlled by a Myenergi Eddi solar diverter, for hot water as we don't have a lot of space for a traditional cylinder.

For full disclosure I work at tepeo. But I like to think I can be objective, and I'm happy to talk frankly about my lived experience with our ZEB and Thermino.
