Vitocell 140-E

The Vitocell 140‑E is a versatile heating water buffer tank designed for modern heating systems with renewable and multiple heat sources. It provides efficient heat storage, low heat losses, and flexible system integration, making it particularly suitable for solar thermal systems, heat pumps, and solid fuel boilers.
When combined with the Vitotrans 353 fresh water module, the Vitocell 140‑E also enables hygienic domestic hot water (DHW) preparation according to the instantaneous water heater principle, without storing drinking water.

Vitocell 140-E

Versatile Application

The Vitocell 140‑E is particularly suitable for solar systems, heat pumps, and solid fuel boilers, as well as hybrid heating concepts.

Low Heat Losses

Highly efficient all‑round thermal insulation minimises standby losses and helps reduce energy consumption and operating costs.

Solar Pumping Station (Accessory)

A pumping station for the solar collector circuit can be mounted directly on the storage tank; for the 400‑litre version, this pumping station is included.

Ideal for Multi‑Generator Systems

Multiple supply and return connections, as well as additional measuring connections, allow easy integration of several heat generators.

Solar Thermal Integration

Optimised for use with Viessmann solar collector systems for efficient heat storage and DHW preparation.

Hybrid System Compatibility

Suitable for integration with:

Heat pumps
Biomass boilers
Gas or oil boilers
Solar thermal systems

Fresh Water Module Integration

The Vitotrans 353 can be mounted directly on the tank, providing controlled and hygienic DHW heating.

Service‑Friendly Layout

Clearly arranged connections simplify commissioning, inspection, and maintenance.
