GEMA FK 600 hygienic storage tank for hygienic domestic hot water heating
The GEMA FK 600 hygienic storage tank is a fresh water combination storage tank with an integrated stainless steel corrugated pipe for hygienic domestic hot water heating using the instantaneous heating principle. The heating water is stored in the tank, while the domestic water is heated on demand via the stainless steel corrugated pipe.
With a net capacity of 551 liters, the FK 600 is suitable for water-based heating systems where storage function and hygienic hot water preparation are to be combined in one system.
Technology & equipment
The FK 600 is designed as a standing storage tank with an integrated stainless steel corrugated pipe. For hydraulic integration, charging and discharging connections, sensor and controller connections, venting, as well as connections for electric heating cartridges are available.
For this storage tank size, three insulation variants are provided: 100 mm EPS, 130 mm EPS, and 150 mm EPS vacuum. This allows the storage tank to be used with different energy efficiency classes and different standby heat losses depending on the selected variant.
Everyday benefits
The instantaneous heating principle supports hygienic hot water preparation, as domestic water is not permanently stored in a large storage volume. At the same time, the storage tank provides heating water for integration into suitable heating systems.
The combination of storage tank, stainless steel corrugated pipe, and selectable insulation makes the FK 600 a versatile storage solution for modernized and newly built heating systems.
System integration & compatibility
The FK 600 can be integrated into suitable heating, solar thermal, and heat pump systems. The storage tank is also suitable for systems with wood heating, provided that the system planning, hydraulics, safety equipment, and operating limits are appropriately designed.
The connections for electric heating cartridges allow for the additional integration of electric backup heating if this is provided for in the system concept.

Installation
The storage tank must be installed standing upright, frost-proof, and on a load-bearing surface. For installation, the tilting dimension without insulation of 1,630 mm must be taken into account.
Hydraulic connection, filling, commissioning, and electrical work on heating cartridges may only be carried out by qualified personnel. The insulation should only be fitted after positioning the storage tank if access paths are narrow.
Notes
The storage tank may only be operated within the intended pressure and temperature limits. Safety valves, venting, shut-off devices, and expansion vessels must be provided in accordance with the system design and applicable engineering standards.
