Product detailed description

Low-temperature wall-mounted boiler Thermona THERM 28 CL with continuous-flow DHW heating

Chimney version

Boilers THERM 14 CL, 23 CL, 28 CL are modern heat sources with continuous-flow water heating, designed for heating and hot water preparation in smaller buildings such as small family houses and flats. They are manufactured in two variants in terms of flue gas discharge – with natural draught (chimney) – variant 23 CLN, and with forced draught (turbo) – variant 23 TCLN.

A new feature is the use of a new digital display, which makes it easier to navigate the boiler's individual parameters and provides a user-friendly setting environment. The boiler's automation is also new, allowing smooth output modulation from 10 to 23 kW for heating.
