What our customers say

How a heat battery boiler works

A tepeo ZEB 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 ZEB 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 ZEB sends it straight to your existing radiators or underfloor heating - just like a traditional boiler would.

Smart charging that knows when and how much to charge

Smart Charging is what makes the ZEB truly intelligent. It learns your home’s heating patterns, responds to the weather and works with your electricity tariff to decide when to charge and how much energy to store – helping you make better use of cheaper electricity and avoid charging when you don’t need to.

That means you can largely leave the ZEB to manage itself. It plans ahead, adapts continuously and keeps optimising in the background.

You can still see what it’s doing and take control at any time through the tepeo app.

Is a heat battery boiler right for 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:

  • 2,000 to 12,000 kWh annual heating and hot water use
  • 60kWh or less daily heat demand
  • Whole-home heat loss of 5kW or less
  • Radiators (including microbore or Thermaskirt) or underfloor heating
  • A hot water tank, small thermal store or space for one

Heat battery vs heat pump

Wondering which is right for your home?

Both use electricity. Both can help reduce home heating emissions. And both have a role to play in the UK’s transition to cleaner heating. But they work in very different ways.

The right choice depends on your property, your heating system, your budget, and how much disruption you are comfortable with during installation.

Read our full comparison to better understand which is right for you.

Upgrading from a combi boiler?

The tepeo ZEB replaces the central heating side of your existing system. If you currently have a combi boiler, you’ll just need a separate hot water solution alongside it.

That’s a normal part of switching to any low-carbon heating, with several options available to suit different homes, spaces and budgets:

Traditional hot water cylinders

A reliable and cost-effective option that stores hot water ready for when your home needs it.

Smart cylinders

A more intelligent way to manage hot water, using controls to heat what you need more efficiently and help reduce unnecessary energy use.

Compact heat batteries

A space-saving alternative to a traditional cylinder, storing energy in a compact unit and delivering hot water when you need it.
