Indirect-heating boiler
With a single coil
All the water is heated right to the bottom
The coil sits at the lowest level: no cold stagnant zones remain — and with them, no conditions for legionella to grow. The high-grade steel vessel operates under internal overpressure of up to 1.0 MPa.

Minimal scale build-up and corrosion resistance.
03
Recirculation-ready
Port N5 — hot water reaches the tap without waiting.
04
High thermal insulation
42 kg/m³ HCFC-free polyurethane foam and an artificial-leather jacket.
