1. Application

The electric boiler ETH electronic is designed for sealed unvented and open vented water heating systems. It is suitable as a
standard heat source or as central heating backup for stoves or solar thermal systems. The ETH can be used in conjunction
with conventional radiators, an underfloor heating system or a ventilation system.
The series enables optimum matching of the output to the building's heat demand.
Standard appliance outputs: 13 kW, 15 kW, 18 kW, 21 kW, 24 kW.
The ETH's integral microprocessor control unit, as well as the use of triacs, guarantees convenient, quiet operation, and the
appliance parameters are matched in real time to the relevant conditions, thus lowering energy consumption.
