Engineering a direct swap

Most electric heating systems struggle to match the high output of a traditional boiler. We designed Hestora to bridge that gap — delivering the exact same warmth your radiators and taps were built for, storing a full day of energy in a compact, boiler-sized footprint.

Matching your home. Most electric heating systems struggle to match the high output of a traditional boiler. We designed Hestora to bridge that gap. By engineering a system that operates at high temperature and high pressure, we can deliver the exact same warmth your radiators and taps were built for. This means you get the performance of a gas or oil boiler without needing to upgrade your pipes or install larger radiators.

A full day of energy. A primary challenge of electric heating is ensuring there is enough power when you actually need it. Hestora is built to contain all the energy required for your whole day in a single charge. It acts as a massive thermal reservoir that sits quietly in your home, ready to provide consistent heat from morning until night.

Charging while you sleep. The secret to heating that does not cost the earth is timing. Because Hestora can store a full day of energy, it is designed to charge during the night when electricity demand is low. By drawing power during off peak hours, you can take advantage of the cheapest and greenest energy available, significantly lowering your running costs without changing your daily routine.

Power in a small space. Space is a premium in the homes we already live in. By using a high temperature and high pressure design, we can create a large thermal energy store within a compact footprint. This advanced engineering allows Hestora to fit into the same space as a standard boiler while providing enough storage capacity to keep your entire home warm and comfortable.
