Kaloris 3W
Hybrid heat storage tank with many connection options for heating devices and heat consumers.
Kaloris 3W – for the most advanced heating systems
Thanks to its three independent coils, Kaloris 3W gives full freedom in designing heating installations. It allows different heat sources and heat consumers to be connected, including systems that require separate technical fluids and different operating parameters.
Three copper coils – even more possibilities
- Upper copper coil: For instantaneous domestic hot water preparation.
- Middle copper coil: For connecting an additional heat source or a separate heating circuit.
- Lower copper coil: For solar collectors, heat pumps or other low-temperature sources.
Kaloris 3W – maximum flexibility and performance thanks to three copper coils
Kaloris 3W is an advanced heating device that allows several heat sources to be connected simultaneously and efficiently supplies multiple heating circuits. Thanks to three independent copper coils, the device can work with solar installations, heat pumps, solid-fuel boilers, gas or oil boilers and fireplaces with a water jacket.
Connection options:
- Different heating systems: Simultaneous operation of open and closed systems with full separation of technical fluids.
- Multiple heat sources: Boilers, heat pumps, solar collectors, fireplaces with a water jacket and photovoltaics.
- Multiple heat consumers: Radiators, underfloor heating, wall heating and domestic hot water.
- Circuit separation: Safe cooperation of installations with different parameters and fluids.
Safe Gravity System (SGS)
When connected to a solid-fuel boiler or fireplace with a water jacket, the Safe Gravity System (SGS) ensures control over correct device operation and protects the system against overheating, even in the event of:
- Power failure
- Circulation pump failure
Instantaneous domestic hot water heating in the Kaloris 3W buffer
Kaloris 3W is an advanced heating system that provides an unlimited amount of hot water thanks to instantaneous heating technology. The copper coil ensures hygienic and safe water heating, while the other coils allow additional heat sources and circuits to be integrated.
Key benefits of Kaloris 3W:
- Unlimited amount of hot water – instantaneous heating guarantees constant access to DHW without waiting.
- Sanitary safety – flow technology prevents Legionella bacteria growth and ensures hygienic water.
- Real-time heating – hot water is delivered without delay and without reheating the tank.
- No water ageing – thanks to the flow system, water is always fresh and safe to use.
- Output of at least 24 l/min – comfort even in homes with high hot water demand.
- Hot water already at a tank temperature of 50°C – energy savings and lower bills.
- No need to replace a cathode or anode – low-maintenance operation.
Copper coil – safety and hygiene
Thanks to the copper coil used in Kaloris 3W, water remains hygienic and safe. Copper inhibits bacterial growth, making the system ideal for places with high sanitary requirements, such as:
- Hospitals
- Kindergartens
- Nurseries
- Schools
Kaloris 3W is an efficient, safe and modern solution that combines automation, energy savings and hygiene, ensuring reliable domestic hot water heating even in demanding conditions.
3-in-1 functionality of Kaloris 3W – a complete heating system
Kaloris 3W is more than just a heat buffer or domestic water heater. Thanks to its unique design, it functions as a hydraulic separator, forming the central heat management point in complex hybrid boiler rooms. The device is designed to integrate different heat sources and support systems requiring different technical fluids and open and closed circuits, while separating and managing heating circuits.
3-in-1 functionality – a complete boiler room in one device
- Buffer: Stores heat from various sources, such as heat pumps, solid-fuel boilers, fireplaces with a water jacket and solar installations. This allows Kaloris 3W to provide stable heat supply and uninterrupted system operation.
- Heat exchanger: Works as an instantaneous domestic hot water heater. Thanks to the copper coil, water heating is hygienic and fully safe, eliminating the risk of Legionella growth.
- Hydraulic separator: This is the central function of Kaloris 3W. The device acts as a natural hydraulic separator, separating and stabilising the flows of technical fluids. It enables connection and integration of multiple heat sources and heat consumers, ensuring performance and operational safety of the entire heating system.
Hydraulic separator in practice
Kaloris 3W as a separator for hybrid boiler rooms enables:
- Combining open and closed systems – simultaneous cooperation of systems with different operating parameters.
- Separation of technical fluids – prevents glycol from mixing with domestic water or other heating fluids.
- Stabilisation of heating flows – ensures even system operation and protects devices from overload.
- Integration of multiple heat sources – such as gas boilers, heat pumps, fireplaces, solar installations and heat recovery devices.
- Optimisation of circulation pump operation – reduces operating costs through precise fluid flow management.
