There’s another way to heat your home with electricity.
If you want to move away from gas but a heat pump isn’t right for your home, discover the tepeo ZEB – a heat battery boiler designed to be installed indoors and work with your wet heating system.
And with winter approaching, now’s a good time to make the switch – before heating installers hit their busiest period.
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.
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.
The heat is stored safely and efficiently inside the boiler’s ceramic core, ready to be released whenever your home needs it.
When your home needs heat, the tepeo boiler sends it straight to your existing radiators or underfloor heating - just like a traditional boiler would.
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.
A heat pump can be a great choice for many homes, but it isn’t the only option. If you’re looking for a different way to move away from fossil-fuel heating, the ZEB gives you another route to an electric home.
A heat battery boiler gives you another way to move away from gas, using your existing wet central heating system without an outdoor unit or a major heating-system overhaul.
The ZEB is designed to work with existing radiators or underfloor heating, so switching to electric heating doesn't necessarily mean redesigning your whole system.
Unlike a heat pump, the ZEB is installed entirely inside your home, so there's no outdoor unit to accommodate.
A ZEB can typically be installed in 1–2 days, using your existing wet heating system and with less disruption to your home.

If you are already exploring greener heating options, a heat pump may be one of the first options you have considered. Heat pumps are an excellent choice for many homes, but no single technology will suit every home.
Our heat battery boiler offers another route.
With heat batteries gaining wider recognition as an important part of the UK’s future heating mix, and tepeo’s £2,500 Early Grant Match available to eligible customers, now is a good time to find out whether a heat battery boiler could be right for your home.
The ZEB charges using electricity, stores energy as heat and release it through a suitable wet central-heating system when your home needs warmth.
Unlike a traditional storage heater, it does not simply warm the room it sits in. It supplies central heating through radiators or underfloor heating.
And, unlike a direct electric boiler, it does not need to draw all its electricity at the moment heat is required. Smart Charging allows the ZEB to store heat during suitable off-peak periods, ready to use later.
This gives you the familiarity of your existing boiler but with greater flexibility over when electricity is used.
| Feature | Heat pump | ZEB heat battery boiler |
|---|---|---|
| How it works | Moves heat from the air, ground or water into your home. | Stores electricity as heat and releases it when needed. |
| Energy source | Electricity. | Electricity. |
| Outdoor unit | Usually required for an air source heat pump. | No outdoor unit required. |
| Indoor installation | Indoor equipment is usually required as part of the system. | Installed indoors as a boiler replacement, subject to space and access requirements. |
| Existing radiators | May need upgrading, depending on the home and required flow temperatures. | Existing radiators can often be retained, subject to a home suitability check. |
| Flow temperature | Usually works best at lower flow temperatures. | Can deliver high flow temperatures, with an output temperature range up to 80°C. |
| Installation disruption | Can involve system redesign, radiator upgrades or changes to heating controls. | Designed to be a lower-disruption alternative to replacing a fossil fuel boiler. |
| Day-to-day heating | Often runs for longer periods at lower temperatures. | Designed to provide a more familiar boiler-like heating experience. |
| Efficiency & flexibility | Very efficient when designed and installed well. | Converts electricity into stored heat and is designed to optimise charging around time-of-use tariffs. |
| Storage capacity | Not applicable in the same way; heat is generated as the system runs. | Stores up to 40kWh of usable heat. |
| Best suited to | Homes suitable for low-temperature heating and an outdoor unit. | Homes where a heat pump may be difficult, disruptive or impractical. |
| Grant support | Currently eligible for Boiler Upgrade Scheme support. | Government has announced future £2,500 BUS support; tepeo offers an early £2,500 grant match. |
By combining your home’s heating patterns with weather forecasts and your energy tariff, the ZEB automatically calculates exactly when, and how much, to charge.
The tepeo App lets you check the ZEB’s status, manage charging preferences, use Away Mode and request a manual ‘boost’.
With a 10-year guarantee and control via the tepeo app, the heat battery boiler combines rock-solid engineering with smart, flexible heating.
Eligible customers can get £2,500 off with tepeo’s Early Grant Match, helping make installation more affordable.
The ZEB is designed to charge using cheaper off-peak electricity, helping keep running costs closer to gas. It also cleverly uses machine learning to forecast heat demand through Smart Charging, meaning you only pay for electricity you’ll actually need.
Can be installed relatively quickly, within 1-2 days and can work with existing radiators and pipework for minimal disruption and cost.
The heat battery boiler does not burn fossil fuels in your home, meaning you’re only heating your home, not the planet.
“I was apprehensive about it at first because it was a new technology. Now, we love it and would choose it again.”
When Gary first introduced his wife Anna to the ZEB in 2022, she was unsure about choosing a technology they hadn’t lived with before.
The couple had also considered a heat pump, but did not want to give up any of their limited outdoor space or have to change existing radiators.
The tepeo heat battery boiler offered a different route, that they’re happy they chose and say they would choose again if they moved to a suitable home.
Our boiler is worth exploring if you:
Every home is different, so the best first step is to complete our home check which will tell you within 60 seconds if your home would be suitable.
The retail price of the tepeo boiler is £6,000.
Our customers can currently receive a £2,500 tepeo Early Grant Match, reducing the price of the ZEB itself to £3,500.
Installation is priced separately because the work varies between different homes, but if you choose to go ahead with a free home survey then a tepeoPRO installer will be able to provide an accurate installation quote then.
Finance options may be available for eligible customers who would prefer to pay for their ZEB and installation through monthly instalments.
Visit our financing page, where you can use our calculator to see what your monthly payments could be.
Finance is subject to status, approval and terms. APR, repayments and total amount repayable may vary.
Tell us about your property, current heating system and plans.
Answer a few more detailed questions so we can understand whether the tepeo boiler may be suitable.
Prefer to talk it through? You can also book a free telephone suitability assessment with a tepeo expert.
If the initial result is positive, a tepeoPRO installer can assess your heating system, radiators, pipework, electrical requirements, hot-water arrangements and proposed installation location.
You will receive a clear installation plan, transparent quote and explanation of any additional work. If a heat battery boiler is not right for your home, we will tell you.
