ThemaCLASSIC traditional gas wall-hung boiler

The Themaclassic is a very compact traditional gas boiler with its 31 cm depth. It can be integrated anywhere (living rooms or ancillary rooms) thanks to its dimensions and its sleek and discreet design. It uses the eBus protocol for communication with Saunier Duval room thermostats, thus offering additional functions compared to a conventional thermostat: management of periods of absence, domestic hot water production, some parameters and heating comfort.

This device, easy to use and install, meets the most common heating and hot water needs.

It exists in a chimney and room-sealed version.
