Indirect-heating boiler

With two coils

Two heat sources on one tank

Two independent coils let you connect two heat sources to a single tank — for example a boiler and a solar collector or heat pump. The lower coil heats the whole volume and removes the legionella risk.

Legionella protection

The low coil position heats the entire volume of the vessel.

03

Recirculation-ready

Port N3 — hot water reaches the tap without waiting.

04

High thermal insulation

42 kg/m³ HCFC-free polyurethane foam and a Termowen outer jacket.
