Product Overview & Application Area
The Schönberg EPS 800 is a thermal storage tank without an integrated heat exchanger for water-based heating systems. With an actual net capacity of 714 liters, it is suitable as a heating water buffer tank for hydraulic integration into suitable system concepts.
The tank is used in heating systems, solid fuel systems, solar systems, and in system environments with combined heat and power plants. It serves as intermediate storage for heating energy and supports orderly hydraulic separation between heat generation and heat distribution.
Technology & Equipment
The EPS 800 is designed as a buffer tank without a heat exchanger. The tank body is made of quality steel S235JRG2, raw on the inside and primed on the outside. It is installed standing on a base ring.
For system integration, 8 charging and discharging connections with 1 1/2 inch female thread, 4 sensor and controller connections with 1/2 inch female thread, one vent connection with 1 1/4 inch female thread, and 2 connections for electric heating cartridges with 1 1/2 inch female thread are available.
Everyday Benefits
A buffer tank supports the time-shifted use of generated heat and can hydraulically stabilize the operation of a heating system. Especially in systems with solid fuel boilers, solar thermal systems, or multiple heat sources, the tank helps to provide generated energy in a controlled manner in the heating system.
The EPS 800 offers a significantly expanded storage volume within the EPS series with a net capacity of 714 liters. The diameter of 790 mm without insulation and the tilting dimension of 1,720 mm without insulation are important planning values for transport, installation, and setup in the technical room.
System Integration & Compatibility
The EPS 800 can be integrated into suitable heating, solid fuel, and solar systems. Use in the vicinity of combined heat and power plants is also possible, provided the system concept is designed accordingly.
The storage tank is intended for heating water and is not designed as a potable water storage tank. The specific hydraulic integration, the sizing of the safety valve, expansion vessel, venting, and control, as well as the selection of suitable components, are carried out as part of the professional planning.

Installation
The storage tank is installed standing on a load-bearing, level, and frost-free surface. When bringing it in, consider the tilting dimension without insulation, the connection positions, sufficient installation clearances, and future accessibility for inspection and maintenance.
The hydraulic connections are made according to the system design. Electric heating cartridges may only be mounted on the designated connection stubs. After installation, all threaded connections must be checked for leaks.
Notes
The type designation EPS 800 does not correspond to the exact storage volume. The actual net volume is 714 liters. Dimensions and connection values must be verified against the specific version before ordering, delivery, and installation.
The storage tank may only be operated within the permitted operating limits. Before working on the tank, the system must be depressurized, cooled down, and secured against accidental refilling.
