Product Overview & Application Area
The Schönberg EPS 1000 is an energy buffer storage tank without an integrated heat exchanger for water-based heating systems. With an actual net capacity of 889 liters, it is suitable as a heating water buffer tank for hydraulic integration into suitable system concepts.
The storage tank is used in heating systems, solid fuel systems, solar systems, and in system environments with combined heat and power plants. It serves as an intermediate storage for heating energy and supports a controlled hydraulic separation between heat generation and heat distribution.
Technology & Equipment
The EPS 1000 is designed as a buffer tank without a heat exchanger. The storage tank body is made of quality steel S235JRG2, is raw on the inside and primed on the outside. It is installed standing on a base ring.
For system integration, 8 supply and return connections with 1 1/2 inch female thread, 4 sensor and controller connections with 1/2 inch female thread, a 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 within the heating system.
The EPS 1000 offers a large storage volume within the EPS series with a net capacity of 889 liters. The diameter of 790 mm without insulation and the tilting dimension of 2,080 mm without insulation are important planning values for transport, installation, and setup in the technical room.
System Integration & Compatibility
The EPS 1000 can be integrated into suitable heating, solid fuel, and solar systems. Use in conjunction with 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 domestic hot water 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, the tilting dimension without insulation, the connection positions, sufficient installation clearances and subsequent accessibility for inspection and maintenance must be taken into account.
The hydraulic connections are connected according to the system concept. Electric heating cartridges may only be mounted on the connection stubs provided for this purpose. After installation, all threaded connections must be checked for tightness.
Notes
The type designation EPS 1000 does not correspond to the exact storage tank content. The actual net content is 889 liters. Dimensions and connection values must be checked against the specific version before ordering, bringing in and installation.
The storage tank may only be operated within the permissible operating limits. Before working on the storage tank, the system must be depressurized, cooled down and secured against unintentional refilling.
