THERM 24 KDNS

THERM 24 KDNS is a stationary gas condensing boiler designed for heating systems. The construction and the arrangement of components makes the boiler suitable for standing on the floor or on a pedestal. The controls are on the top side of the boiler, as well as distribution connections, thanks to which the boiler can be easily installed instead of older types. It is ideal for installation in cellars and basements with a very low ceiling where a standard hanging boiler cannot be installed.

The boiler may be equipped with a condensate pumping station that is not standardly included with the boiler. Heating domestic hot water can be provided in an external non-heating tank, using an external three-way valve. For heating, the boiler has a heating capacity from 4.6 to 26.0 kW.
