Zero Emission Boiler (ZEB)
Using off-peak electricity, the ZEB charges up when electricity is cheaper and greener, heating up a thermal core inside the ZEB. This stores energy until it is needed and releases it when your thermostat calls for heat (either for heating or hot water). You can keep your existing controls, pipework, radiators and cylinder - making the ZEB a very simple installation compared to many other low carbon options.
The ZEB’s intelligent charging algorithm looks at your tariff, the weather, the grid carbon intensity and how much heat your home uses to automatically charge up - keeping running costs & carbon low, while avoiding wasted heat.
