Simplicity That Works for You

Simplicity That Works for You

ESSENTA is built for peace of mind. Install it, switch it on, and forget it’s there. Smart, flexible connections allow for quick installation even in tight spaces or right up against a wall. Operation is straightforward, with advanced settings to suit more demanding users. Everything is designed so hot water is always available – without complex decisions or extra effort.

Long-Term Savings & Sustainability

ESSENTA operates with exceptional efficiency, using up to 75% less energy than conventional water heaters. The savings are significant. Built for a long service life, it represents a reliable investment for the future. While heating, it simultaneously cools nearby rooms for free and can make use of surplus energy from solar panels to heat domestic hot water. Save even more, avoid running the boiler in summer, cut your CO₂ emissions, and contribute to a more sustainable future.

Smart Placement That Saves Space

Smart Placement That Saves Space

ESSENTA adapts to your space – not the other way around. Thanks to its thoughtfully designed air connections, you can place it right against a wall or even in a corner without restricting airflow. Air intake and exhaust are available from the top or the sides, simplifying installation and eliminating the need for extra ductwork. Save space, reduce installation costs, and ensure optimal performance – no matter where you install it.

Heats Water, Cools the Air

While heating water, ESSENTA draws heat from the surrounding air – providing free cooling to nearby spaces such as pantries, cellars, or garages. This effect is especially welcome wherever you want to maintain lower temperatures, for example when storing preserves or other temperature-sensitive items. Cooling happens quietly, with no extra energy consumption or additional controls required.

Installation Options

Indoor Installation

Indoor Installation

ESSENTA draws heat from the room’s air and returns pleasantly cool, dehumidified air back into the space. An ideal solution when the heat pump is located in a room you wish to keep cool and dry, such as a cellar or pantry.

AIR SOURCE SWITCHING

AIR SOURCE SWITCHING

+

The system offers a choice: air can be drawn from and returned to the same room, an adjacent room, the outside, or a combination – depending on where you want the cooling effect.

DUCTED INSTALLATION

DUCTED INSTALLATION

+

ESSENTA can be installed in one room while drawing and returning air through ducts to a different room or to the outside. This way, it has no impact on the temperature or climate of the room where the unit is located.

BIOMASS BOILER INTEGRATION

BIOMASS BOILER INTEGRATION

+

ESSENTA works alongside pellet, wood, or woodchip boilers. In summer, it provides hot water without the need to run the boiler; in winter, it reduces fuel consumption and adds an extra layer of comfort.

HEAT RECOVERY UNIT EXHAUST AIR

HEAT RECOVERY UNIT EXHAUST AIR

+

Heat that would otherwise be lost through the ventilation system is captured by ESSENTA and converted into energy for water heating, while the cooled air is returned to the heat recovery unit’s exhaust duct.

CASCADE CONNECTION

CASCADE CONNECTION

+

Multiple ESSENTA units can be connected in cascade. They operate in a coordinated sequence based on demand and together ensure sufficient hot water even for larger buildings, such as apartment complexes, sports centres, or commercial properties.
