Electric Boilers and Thermal Energy Storage
AmbiHeat® — Heat when you need it. Cost‑effectively and flexibly
Electric Boilers and Thermal Energy Storage for Flexible, Low‑Emission Heat Production
The AmbiHeat plant solution offers energy companies and industry a way to produce and store heat in a market‑driven, emission‑free, and highly flexible manner.
The system uses electric boilers to take advantage of low‑cost electricity windows, stores the heat in thermal energy storage, and releases it during consumption peaks, optimizing the total cost and load of heat production.
AmbiHeat Electric Boilers
Electric boilers enable heat production by utilizing periods of affordable renewable electricity, while reducing the carbon footprint of district heating and industrial processes and decreasing the need for combustion‑based production.
An AmbiHeat electric boiler plant is a factory‑built, turnkey solution delivered ready for installation at the selected site. The delivery includes everything from engineering and automation to commissioning.
Electric boilers enable
LOW-EMISSION HEAT PRODUCTION
PRODUCTION SCHEDULING BASED ON MARKET PRICES
REPLACEMENT OF COMBUSTION-BASED PEAK PRODUCTION
When Is an Electric Boiler a Good Solution?
AmbiHeat electric boilers are ideally suited for:
- Peak and backup production – rapid heat availability during consumption peaks without combustion
- Utilization of low‑cost electricity – heat production during the cheapest electricity hours (e.g. windy periods)
- Supporting carbon‑neutral production – fully electric heat generation reduces fossil peak loads
Thermal Energy Storage – A Critical Part of Modern Heat Production
Whether the AmbiHeat plant includes a heat pump, an electric boiler, or both, an integrated thermal energy storage system enables efficient storage and use of produced heat at different times.
Seamlessly integrated AmbiHeat thermal energy storage solutions are a key component of modern, carbon‑neutral and electric heat production.
What Is Thermal Energy Storage Used For?
Load balancing in heat production
Heat is produced when it is affordable and stored for use during demand peaks.- Utilizing electricity markets
Flexible storage enables production to be controlled based on electricity price and availability. - Optimizing heat pump plants
Heat pumps can operate at a steady, energy‑efficient load while storage absorbs demand fluctuations. - Backup capacity
Thermal storage acts as a reliable heat reserve during peak loads and expensive electricity hours.
AmbiHeat Plants Are Delivered as Factory‑Built Turnkey Solutions
Each modular AmbiHeat plant is designed to meet customer‑specific needs and can be equipped with:
- Electric boilers
- Heat pumps
- Thermal energy storage
The system can later be scaled according to changing production requirements.

Scope of Delivery – AmbiHeat Electric Boiler Solutions
An AmbiHeat electric boiler solution includes:
- Electric boiler and associated automation
- Plant building or container with engineering
- Connections to existing systems
- Integrated market‑based control
- Commissioning and monitoring
- Optional integration with AmbiHeat heat pumps and thermal storage
Why Include Thermal Energy Storage in an AmbiHeat Solution?
With AmbiHeat heat pumps, it is often possible to produce more heat than the district heating network can accept at a given time. Similarly, heat produced by electric boilers during low‑cost electricity hours cannot always be fed directly into the network.
In these situations, integrated thermal energy storage enables heat to be stored and used when it is most needed.
AmbiHeat thermal storage enables in particular:
- Shifting production to lower‑cost hours
- Joint optimization of heat pumps and electric boilers
- Lower emissions and production costs
- Improved reliability of heat supply and smooth peak management
