Tepeo Zero Emission Boiler (ZEB®)

Meet the ZEB

Looking to reduce your environmental impact? The ZEB uses electricity to supply your heating, charging up and storing most of the heat your home requires at off-peak times. This can make it a more cost-effective and cleaner option compared to existing boilers.

Cut Emissions

Powered by electricity, the ZEB is a cleaner alternative to your existing boiler as it doesn’t release any pollution directly and it stores heat at the greenest times.


The ZEB stores most of the heat your home requires during off-peak times to be used on demand, keeping electricity costs low.

Easy to Install

The ZEB is a direct replacement for your existing boiler, meaning installation typically takes only 1-2 days and requires minimal changes to the home.

Smart & Flexible

The ZEB intelligently stores the right amount of heat based on your needs, the weather and your tariff. It can also be controlled from anywhere with our tepeo App.
