Overview
Stainless steel (304 / 316L / Duplex 2205) hot water tank with a coil, to pair with any heat pump. The Heat Pump Water Tank is part of Pecol's Storage Water Heaters range (stainless steel tanks for heat pump & solar systems). Size range: 200 – 400 L.

Key features
Coil choices
Smooth, wave, aluminium or copper coils in 22, 28, 32 or 35 mm.
Duplex 2205 option
Duplex 2205 has far better pitting-corrosion resistance and strength than SUS304 or SUS316L, so tanks last longer.
100% leakage tested
Every tank is held at 0.8–1.0 MPa for 3 minutes with no bubbles or deformation.
Quality checked
Salt-spray corrosion tests, endoscope inspection after pickling and infrared imaging of the polyurethane foam.
