A smarter way to heat your home

Meet the ZEB – tepeo’s heat battery boiler. It replaces your fossil-fuel boiler with fully electric heating, while working with your existing radiators and without the need for an outdoor unit.

  • Stores off-peak electricity as heat
  • Works with your existing wet heating system
  • No outdoor unit or flue needed

Another route to electric heating

Heating our homes has an important role to play in tackling climate change, which is why moving away from fossil fuels and towards cleaner electricity matters.

Heat pumps are a great solution for many homes – but they aren’t the only route to electric heating. We believe homeowners need practical options that work for different properties and circumstances.

The ZEB has been explored by Everything Electric, featured on BBC South Today and discussed across the home-energy industry as a practical alternative for homes where a heat pump may not be the right fit.

How a heat battery boiler works

A tepeo heat battery boiler works a little differently behind the scenes, while heating your home in a way that feels reassuringly familiar.

It simply charges, stores heat and releases it when you need it.

1

Charges like a battery

The tepeo heat battery boiler uses smart charging to work out the best times to heat its ceramic core, making the most of cheaper, lower-carbon electricity and your energy tariff.

2

Stores heat for later

The heat is stored safely and efficiently inside the boiler’s ceramic core, ready to be released whenever your home needs it.

3

Heats your home as normal

When your home needs heat, the tepeo boiler sends it straight to your existing radiators or underfloor heating - just like a traditional boiler would.

Get off gas without changing your home

We’ve made it as easy and quick as possible to switch from your existing boiler to a low-carbon alternative

Designed to replace your existing boiler

The ZEB works with your existing pipework, radiators and underfloor heating. Installation can often be completed in just 1-2 days.

Make the most of cheaper electricity

Smart charging learns what your home needs, using your tariff, energy use and local weather to automatically charge at the most effective times.

No outdoor unit needed

Everything is installed indoors, so you can move away from gas without giving up garden or outdoor space.

A practical move away from gas

Heat your home without burning fossil fuels, while keeping the familiar central heating experience you’re used to.

Could a ZEB work in your home?

Our heat battery boiler is designed for homes that want familiar central heating without gas, oil or LPG.

It is 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:

  • Up to 12,000kWh annual heating and hot water use
  • 60kWh or less daily heat demand
  • Whole-home heat loss of 5kW or less
  • Radiators or underfloor heating
  • A hot water tank, or space for one
