RVS Buffertank BT-500L: Stainless Steel Buffer Tank for Heat Pumps

The RVS Buffertank BT-500L 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.

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.

Safety requirements
The storage vessel must be protected against overpressure at all times.
We recommend installing the following safety accessories:
* Safety valve and inlet combination
* Nexus sanitary expansion vessel model DS-DSV
* Nexus expansion vessel model Nexus ERCE
The required expansion vessel capacity must be calculated according to the total system volume and operating conditions.
