How does the ZEB work?

The ZEB is an innovative low carbon alternative to a fossil fuel boiler, however being a heat battery, it will work slightly differently to your existing boiler.

Just like your phone battery charges up using electricity and draws down on this stored energy as needed, the ZEB also uses electricity to charge up, storing energy as heat that can be used on demand when you want to heat your home. Using a Smart Charging algorithm, the ZEB intelligently stores the right amount of heat based on your needs, the weather and your tariff, mostly charging up at off-peak times e.g at night to minimise electricity costs and topping up during the day if needed. How long a full charge lasts depends on the property size, heating usage and the weather.
