What is a heat battery boiler?

The tepeo heat battery boiler charges using electricity, stores that energy as heat and then releases it through a wet central-heating system when your home needs warmth.

It charges like a battery and heats like a boiler.

It is not a storage heater and it is not a standard direct-electric boiler: a storage heater usually warms the room it sits in, and a direct electric boiler draws electricity at the moment heat is needed.

The tepeo ZEB heat battery boiler stores heat in advance. Smart Charging considers your tariff, local weather and expected heat demand when deciding when and how much to charge.

That means familiar radiator heating with greater flexibility over when your stored off-peak electricity is used.

Why consider a heat battery boiler?

Heating Icon

Familiar central heating

The ZEB delivers heat through suitable radiators or underfloor heating, so the way your home feels remains familiar.

Smart Charging Icon

Smart Charging

The ZEB considers your electricity tariff, the weather forecast and likely heating demand when deciding when and how much to charge to be efficient.

Heat stored for later

Unlike a direct-electric boiler, it does not need to draw all its electricity at the moment your home needs heat.

Green Energy Icon

No fossil fuel burned

The ZEB does not burn gas, oil or LPG at the point of use.

Volatility Icon

Less volatility exposure

Electricity prices change, but moving away from gas, oil or LPG can reduce your reliance on internationally traded fossil fuels.

Customer Support Icon

Continued support

tepeo is proud of its customer service and provides ongoing customer support, system monitoring and care plans. We also have a friendly customer community and Help Centre.

Get your heating sorted before you need it

When the weather is warm, replacing your boiler can feel like a problem for another day.

But waiting until it fails may leave you comparing unfamiliar systems urgently, while your home is getting colder. Starting now give you time to understand the options, check what suits your property, and plan any work properly.

How much is a tepeo heat battery boiler?

The ZEB has a retail price of £6,000, but we’re currently offering £2,500 off through our early grant match, reducing the product price to £3,500.

Installation is priced separately because every home is different. Once you’ve completed our initial home check and passed, we will put you in touch with your local tepeoPRO installer, who will carry out a free in-person home survey and provide an accurate quote.

Find out more about our finance options if you’d prefer to spread the cost of your boiler and installation costs.

Replacing your current boiler

In many suitable homes, the tepeo boiler can replace the central-heating function of a gas, oil or LPG boiler.

It can work with suitable radiators or underfloor heating. Existing radiators and pipework can often be retained, although this must be confirmed through our free home survey.

If you currently have a combi boiler, a tepeo ZEB will replace the central heating side of the system. A separate hot-water solution will normally be required, such as:

a traditional hot-water cylinder
a smart cylinder
a compact phase-change hot-water battery

Our experts can help guide you through hot water solution.

Quick and easy installation

The thing we hear from our customers time and time again is how “quick and easy” their tepeo boiler installation was.

Our ZEB takes around 1-2 days to install, although the final timescale depends on your home and the work required.

If your home is suitable for a ZEB, we recommend you carry out a free in-person home survey with your local tepeoPRO installers, who will assess your home in more detail and provide an accurate installation quote.

How do the main boiler-replacement options compare?

Heat pumps, direct-electric boilers and heat battery boilers can all provide alternatives to fossil-fuel heating. The right option depends on the property, heating demand, available space and the work involved.
