TESY 800L V95 F43 P4 is a high-capacity thermal accumulator designed to store a significant amount of heat for large heating systems. The model is used in private homes, hotels, commercial facilities and heating plants where high thermal stability and maximum boiler efficiency are required.
Increased volume — 800 liters
Ideal for solid-fuel boilers that operate in cycles and require accumulation of excess heat. The buffer tank protects the boiler from overheating and extends its lifespan.
Powerful thermal insulation — 50 mm
A highly efficient CFC-FREE polyurethane foam is used, ensuring minimal heat loss even with large water volumes.
Maximum connection flexibility
▪️ 4 temperature-sensor pockets,
▪️ extended 4 + 5 inlet / outlet configuration — enables integration into complex heating systems, including hydraulic separators, distribution manifolds and backup heat sources.
Easy maintenance
A large drain outlet simplifies water removal, the PVC casing protects the body, and the vertical design allows installation even in narrow technical rooms.
Full safety package
The integrated safety valve ensures stable and safe operation during pressure fluctuations.
Suitable for systems with
▪️ multiple boilers,
▪️ heat pumps,
▪️ water-based fireplaces and solar collectors,
▪️ large-area underfloor heating systems.
