Upgrading your boiler the missing puzzle piece?

Many people think that the only way to go low carbon in their home is either with a heat pump or a direct electric boiler. But there’s another excellent option for those who want to keep it low cost and simple: a heat battery boiler.

The tepeo boiler charges using off-peak electricity and stores that energy as heat, ready to use when your home needs it.

Smart Charging uses your tariff, local weather forecasts and expected heating demand to decide when, and how much, to charge – all of which can be monitored and controlled via the app.

Many customers find their running costs are broadly similar to gas heating with a familiar heating experience as well.

Kevin had already reduced his natural gas use by 65% with solar, EV charging, A2A heat pumps used for air conditioning and smart energy monitoring.

But he still needed one thing: a way to replace the central-heating role of his old gas boiler. The tepeo ZEB became the key to completing the switch.

It now works alongside Kevin’s electric setup, helping him disconnect from gas completely while keeping familiar central heating. Kevin told us it costs him just £1.60 to fully charge his ZEB through his Octopus tariff.

And with tepeo’s £2,500 Early Grant Match, Kevin was able to make the move sooner and save even more.

Heat pumps work well in many properties. But Britain’s homes are varied and no single low-carbon heating system will suit every one.

A heat battery boiler may be worth considering wheer:

• there is limited space for an outdoor unit
• planning or property constraints make an outdoor installation difficult
• you want to retain a suitable wet central-heating system
• you would prefer a potentially lower-disruption boiler replacement
• your property’s heat demand, electrical supply and indoor space are suitable

The right answer starts with the property, not the technology.
