Котел газовый ITALTHERM серии CITY CLASS F (Италтерм Сити Класс Эф) — это новый уровень комфорта и эффективности для Вашего дома! CITY CLASS 25 F предназначен для настенной установки и полностью готов к монтажу. Благодаря своим компактным размерам, данный котел может быть установлен практически в любом помещении (на кухне, в гараже, в кладовой и т.д.) Вашего дома или квартиры.

Котел оборудован специальным вытяжным устройством, позволяющим данному котлу работать с мобильным (длинною около 1 метра) коаксиальным дымоходом. Это крайне удобно, если в помещении, где планируется установка CITY CLASS 25 F, нет отдельно возведенного классического дымохода, либо данный дымоход имеет хронические проблемы с тягой.

Газовый водогрейный котел CITY CLASS 25 F имеет закрытую камеру сгорания. Это очень удобно, так как весь кислород, необходимый для поддержания процесса горения, поступает в данный котел с улицы через дымоход.

В конструкцию отопительного аппарата CITY CLASS 25 F включен встроенный водонагреватель для системы горячего водоснабжения. Это удобно, практично и экономит Ваши средства на покупку отдельного водонагревателя.

Котел является энергозависимым — для его работы требуется подключение к электрической сети. Все газовые котлы ITALTHERM проходят тестирование на заводе (розжиг, проверка герметичности водяного и газового контуров, регулировка автоматики и др.), что обеспечивает дополнительные гарантии надежности и качества.
