Outdated Product
Wall-mounted double-circuit turbocharged gas boiler for heating and hot water supply of a large city apartment or a detached house up to 144 m². A decent thermal power (18 kW) provides up to 10 L / min of hot water with a temperature of up to 55 °C (provided that the water is heated from the initial temperature by 30 °C). It is positioned as a product of the basic price category, adapted to work with natural and liquefied gas. There are two modes of operation of the heating circuit. In the first, the coolant is heated up to 85 °C and circulates through the system with classic metal radiators. In the second, automation limits the water temperature to 45 °C, which is the best option for underfloor heating systems. The Hi-Therm Optimus 18 double-circuit gas boiler is equipped with a closed-ty...pe combustion chamber with forced removal of combustion products, which guarantees safe operation when installed in residential areas. The modern electronic control scheme and modulating burner with flame ionization control allow you to quickly change the heat output, preventing gas overruns. This design and advanced engineering solutions provide high efficiency and significantly reduce the overall cost of organizing / maintaining a heating system and hot water supply. The boiler is equipped with standard safety systems and safety devices.
