Buffers

Without Heat Exchangers / Vertical Floor Standing
  • Made from high grade Duplex LDX 2101 stainless steel, extremely resistant to pitting corrosion
  • All welds are butt welded
  • Made by high quality welding process TIG (GTAW), eliminating the possibility of crevice corrosion
  • The complete tank is pickled and passivated both inside and outsider
  • No sacrificial anodes required
  • Thick insulation polyurethane foam layer - λ = 0,022 W/mK

Major role in both domestic hot water (DHW) and hydronic heat pump systems

Buffer tanks store the water that has been heated providing thermal stability and enabling the efficience in peak demands.

In DHW applications, a buffer tank stores hot water so that you can get instant hot water from taps or showers, even if your heat pump takes its time warming things up.
