Three functions, one tank
Combines heating buffer volume, domestic hot water preparation and solar energy support.
Hygienic Hot Water and Solar-Assisted Storage
Solikombi Series
The Solikombi Series combines heating buffer volume, solar energy support and domestic hot water preparation in a single tank. Domestic water is heated as it flows through an AISI 316L stainless steel heat exchanger; it is not stored in the tank. Available in 300, 500, 800 and 1000 L nominal models.

Buffer volume for heating circuits
Dual AISI 316L heat exchangers
Solar energy support
Highlights
Three functions in one tank. Flexible integration.
Solikombi brings heating circuit buffer volume, domestic hot water preparation and solar energy support together in one system.
Hygienic hot water
Domestic water is heated as it flows through an AISI 316L stainless steel exchanger instead of being stored in the tank.
Dedicated solar exchanger
A second AISI 316L exchanger connects the solar circuit. The tank can be integrated with heat pumps and boilers.
Four sizes, tailored insulation
The 300/500 L models use 50 mm PU insulation; the 800/1000 L models use 80 mm sponge insulation.
Solar support, hot water and buffer volume in one.
Solikombi combines solar energy with a heat pump or boiler in one heating system. Domestic water is heated on demand in a separate stainless steel exchanger, while the tank adds buffer volume to the heating circuit.

Technical notes
Model names indicate nominal capacities; actual tank volumes are listed separately above. Both heat exchangers are made of AISI 316L stainless steel. The 300/500 L models use 50 mm PU insulation; the 800/1000 L models use 80 mm sponge insulation. An electric heater is optional; no anode rod is required. G denotes the threaded connection size. Follow the current manufacturer manual for installation.

Operation
How does Solikombi work?
Combines buffer volume, on-demand hot water and solar support.
Operation
How does Solikombi work?
The tank stores heating water as buffer volume. Domestic water is heated as it flows through an AISI 316L exchanger; a second AISI 316L exchanger transfers heat from the solar circuit. It can be designed for heat pump or boiler systems.
Capacity
Which Solikombi model should I choose?
Compare the 300, 500, 800 and 1000 L nominal models.
Capacity
Which Solikombi model should I choose?
Consider heating circuit volume, heat source capacity, hot water demand and the solar circuit together. Actual tank volumes for the nominal 300/500/800/1000 L models are 245/460/850/1030 L.
Maintenance
What about the electric heater and maintenance?
Electric heater optional; no anode rod required.
Maintenance
What about the electric heater and maintenance?
All four models have a connection for an optional electric heater. No anode rod is needed. Check system pressure, exchangers and pipework per the manufacturer's manual.
