Kaloris 2W
Kaloris 2W – an ideal connection system for central heating, DHW and solar installation
With Kaloris 2W, your heating installation works efficiently, economically and fully automatically, regardless of the heat sources and solar installation used.
Versatility of Kaloris 2W – connecting multiple heat sources and solar collectors
Kaloris 2W is a versatile heating device that offers all the functionality of Kaloris 1W, with an additional advantage: the ability to connect a glycol-based solar installation thanks to a special built-in copper coil.
Key difference – additional solar coil
Unlike Kaloris 1W, Kaloris 2W is equipped with an additional copper coil that enables direct connection of a glycol-based solar installation. This allows the system to use solar energy both for domestic hot water heating and for supporting central heating.
Connection options:
- Glycol solar collectors (thanks to the additional copper coil)
- Fireplace with water jacket
- Solid-fuel boiler
- Oil boiler
- Gas boiler
- Electric boiler
- Heat pump
- Photovoltaics
Safe Gravity System (SGS)
When connected to a solid-fuel boiler or fireplace with a water jacket, the Safe Gravity System (SGS)
provides full control over device operation, protecting the system against overheating even in the event of:
- Power failure
- Circulation pump failure
Instantaneous domestic hot water heating in the Kaloris 2W buffer
Key benefits of Kaloris 2W:
- Free DHW heating – from April to September, solar energy provides hot water without additional costs.
- Support for central heating – during transitional periods, the solar installation supports the heating system and reduces consumption from other energy sources.
- Unlimited amount of hot water – instantaneous heating technology ensures continuous DHW availability.
- Safety and hygiene – instantaneous heating prevents Legionella bacteria growth.
- Real-time heating – without waiting for the tank to reheat.
- No water ageing – the water is always fresh.
- Output of at least 24 l/min – suitable even for high user demand.
- Hot water already at a tank temperature of 50°C – energy savings and lower bills.
- No need to replace a cathode or anode – lower operating costs.
Copper coil – hygiene and performance
Thanks to the copper coil used in Kaloris 2W, the water remains hygienic because copper inhibits bacterial growth.
This is an ideal solution for places with high sanitary requirements, such as:
- Hospitals
- Kindergartens
- Nurseries
- Schools
3-in-1 functionality of Kaloris 2W
Kaloris 2W is an advanced heating device that combines the functionality of three key elements of a heating installation. Instead of installing several separate devices, Kaloris 2W performs their roles at the same time, providing high efficiency, energy savings and fully automated operation.
- Buffer: Stores heat from various energy sources, such as boilers, heat pumps, solar collectors or fireplaces with a water jacket. It ensures continuous heat supply and stable operation of the entire heating installation.
- Heat exchanger: Works as an instantaneous domestic hot water heater, delivering water in real time without reheating the tank and without the risk of Legionella growth.
- Hydraulic separator: Enables the connection of multiple heat sources and simultaneous supply of central heating, domestic hot water and various heat consumers. Importantly, Kaloris 2W also allows technical fluids to be separated, increasing the safety and reliability of the whole system.
