Replace your gas or oil boiler with the heat battery boiler by tepeo – a practical alternative for homes where a heat pump may not be the right fit.
Our heat battery boiler charges using off-peak electricity, stores energy as heat in a high-density ceramic core, then releases that heat into your home when you need it.
So you get everything you like about central heating – powered by smart electricity.
Charge. Heat. Repeat.
Our heat battery boiler is designed for homes that want familiar central heating without gas, oil or LPG. It can be a great heat pump alternative if you do not have outdoor space, want to avoid a major retrofit, or need a lower-disruption installation.
The ZEB typically works best in homes with:
Every home is different, so we’ll confirm suitability through a short home check.

The ZEB doesn’t just charge blindly. It thinks ahead. By combining your home’s heating patterns with weather forecasts and your energy tariff, it automatically calculates exactly when and how much to charge.
You get all the warmth your home needs, powered by the cheapest, greenest electricity windows available.
Effortless low-carbon heating, handled automatically. Good for the planet as well as your wallet.
See what our customers have to say about the ZEB and the installation process.
Really attentive customer service from Tepeo. Nothing is too much trouble. We had some questions before and after installation that were all answered very thoroughly. Now that we’re used to the ZEB, we have got it set up so that it best suits our needs. Oh, and our cat loves sleeping on it!
“The ZEB is easily controlled by an app from your mobile phone, it includes lots of functions so you can program it to suit your needs and take advantage of any smart electricity tariffs you might have (…). The ZEB is a great alternative to a heat pump if like me it isn’t suited to your home.”
For us, the ZEB was much cheaper to install than a replacement oil boiler as the regulations have changed and we would have had to have a new flue or put the boiler outside. After a year, we think running costs are similar to oil. We had one breakdown but Tepeo sent a technician to replace a faulty part the next day. Weekday support is excellent. Delighted we went with a green solution. A heat pump was not suitable for our house. The ZEB is an excellent product and deserves to be much better known.
“The ZEB was installed neatly and easily in our cupboard under the stairs. Through last winter we stayed warm and let the ZEB do its thing with choosing the cheapest and greenest times to charge overnight. Customer support from tepeo has been great and the app is very user friendly”
“The ZEB works in our house, pretty much the same as our gas boiler. There’s not been any practical differences. And it’s all on our existing controls – we didn’t even have to change the settings! We didn’t have to change any of the radiators and it only took a day in the end to install.”
“The ZEB is a great product which we are very pleased to have replaced our gas boiler. Our house is as warm as it ever was with the old boiler and we have much more control over its operation. tepeo have been excellent in all aspects during and since our installation.”
The tepeo ZEB is a heat battery boiler designed to seamlessly replace the central heating side of your old system. If you currently have a combi boiler (which handles both your radiators and your hot water in one box), you will simply need to add a separate hot water solution alongside your ZEB.
This is a very standard part of moving to zero-emission heating, and there are several fantastic, low-carbon options to fit your space and budget:
The classic, cost-effective choice.
Highly efficient, heating only the water you actually need.
Ultra-small thermal stores that provide hot water on demand, perfect for tight spaces.
Don’t worry, your tepeoPRO installer will assess your home and recommend the perfect fit.
Take control of your heat battery boiler from anywhere with the tepeo app. The app gives you a clear view of what your ZEB is doing, including its live status, charge history, local grid carbon intensity, and the carbon emissions from your ZEB’s charging over time.
You can also adjust your heating on the go: set Away Mode, manage Smart Charging, or Boost your ZEB on a cold day when you need extra heat.
Smart, simple and reassuring, so you always know what your heat battery boiler is doing and can stay in control of your home heating.
