RVS Buffertank BT-25/WM SMALL-C2: Stainless Steel Buffer Tank for Heat Pumps

The RVS Buffertank BT-25/WM SMALL-C2 is a stainless steel buffer tank for heat pump systems, central heating installations and professional HVAC applications. It increases system volume, helps reduce cycling and supports more stable hydraulic operation.

Stainless Steel Construction and Reliable Thermal Storage

The tank is manufactured from stainless steel AISI 304 and designed for long-term use in technical installations. The combination of stainless steel, PU insulation and practical connection options makes this model a durable buffer solution for installers.

Energy Efficiency Class A and PU Insulation

With Energy Efficiency Class A, the high-quality PU insulation helps reduce heat loss, keeps stored heat at temperature for longer and supports lower energy consumption in heat pump and heating systems. This makes the Nexus stainless steel buffer range an efficient choice for reliable thermal storage, buffer volume and long-term energy savings.

Hydraulic Stability for Heating Systems

By adding buffer volume, the heating system can operate more smoothly. This supports stable flow, less frequent start-stop operation of the heat source and reliable long-term system performance.
