Saunier Duval Thelia Condens 25 A 25 kW

An intelligent boiler for savvy owners

The stylish and compact Saunier Duval Thelia Condens 25 A boiler provides efficient heating of a room up to 200 m². This double-circuit boiler allows you to simultaneously provide heating and hot water. It also offers a summer mode, in which only hot water is supplied, which helps avoid the cost of additional electric boilers or gas water heaters between heating seasons. The boiler is equipped with an eBus electronic bus, which allows you to combine several compatible boilers into a single system and connect many additional control devices. The operation of the device is controlled by built-in systems. Hot water supply is activated automatically when the tap is opened, without the need for preliminary ignition. Sensors monitor the draft level, gas pressure, heating temperature and the presence of flame, ensuring comfort and safety when heating.

Beneficial condensation

Saunier Duval Thelia Condens 25 A has a high efficiency (108.5%), achieved thanks to the technology of recycling thermal energy (condensation type). The aluminium-silicon alloy heat exchanger has optimal thermal conductivity and fusibility characteristics. The boiler allows you to save up to 10–15% of gas and ensures that you quickly reach the required temperature (the “Hot start” function takes about 2 seconds). The closed combustion chamber allows the boiler to be installed in confined spaces without natural ventilation, for example, in basements or storage rooms. Combustion products are discharged to the street through a two-level air duct system. This is especially important for private houses and apartments, where regular ventilation in winter is difficult.
