Not every home is "heat pump ready." We built the ZEB heat battery for the rest

Simplified for every professional sector. Empowering the UK’s installers, developers, and housing providers to solve the toughest retrofit and new-build challenges. The ZEB delivers low cost, stored heat with no outdoor units or radiator upgrades, offering a rapid, low-disruption alternative to heat pumps

Installers

With free expert training on our innovative heat battery, you can learn how to specify, sell, and install the ZEB in half a day.

Social Housing

Deliver low cost, stored heat across your entire portfolio via an innovative heat battery that eliminates retrofit headaches.

New Build

The versatile low-carbon solution that reduces installation complexity and fits where heat pumps can't.

Electrifying heat. Simplified by smart thermal storage

The transition to Net Zero is a massive undertaking. While Air Source Heat Pumps are part of the solution, they aren’t a universal fix. Between external space constraints, internal radiator upgrades, and lifestyle changes, some projects need a different approach.

Boiler Logic:

High-performance heating with a 15kW peak output and 9kW sustained discharge. It delivers heat to radiators and underfloor systems with flow temperatures from 35–80°C, mimicking the performance of a traditional boiler.

low cost, Stored Heat:

An innovative core stores up to 40kWh of heat to be used on demand. The ZEB automatically charges when electricity is cheapest and greenest, decoupling energy consumption from heat delivery.

Frictionless Installation:

A straightforward, heat-only boiler replacement that works with existing radiators and hot water tanks. With no outdoor units required and connecting to existing pipework it is typically installed in just 1–2 days.

How the ZEB works

The ZEB is powered by electricity and works like a battery to store energy as heat until it is needed. Electric heating elements charge up a "core" inside the ZEB - storing a lot of energy in a small foot print.

It’s not just a boiler. It’s a Smart Energy Manager

The ZEB doesn’t just store heat; it thinks. By integrating with the tepeo Cloud, it monitors weather forecasts, grid carbon intensity, and dynamic energy tariffs.

Learning

The ZEB learns how much heat your home needs and uses local weather forecasts to make a prediction for the day ahead.

Adapting

Next, the ZEB works out how much to charge and when to do it based on your tariff pricing, the grid carbon intensity and predicted heat demand.

Adjusting

As the day unfolds, the ZEB constantly checks its level of charge and re-calculates to make adjustments throughout the day if needed.

Control

You are always in control - the tepeo app lets you adjust or set how the ZEB should charge and you can always boost the ZEB manually.
