Gas condensing Boiler. Semia Condens 25A

Description

Saunier Duval Semia Condens 25A wall-mounted gas condensing Boiler.

The SemiaCONDENS thermal power plant is part of the group of condensing power plants, more efficient and quieter power plants, but also reliable and easy to use.

This condensing boiler model falls into class 5 NOx, the most efficient according to the EU standard in terms of noxious emissions. Operating noise is reduced by incorporating a superior housing insulation. The built-in pump has 2 speeds that can be changed automatically depending on the pressure losses in the heating system, thus avoiding the production of noise.

The increased modulation range (thermal power 5 kW → 25 kW on a.c.m and 5 kW → 18 kW on heating) and high efficiency, as well as the price / quality ratio make this boiler made in France reliable and accessible to everyone.

Constant ambient temperature regardless of the weather;
Ample modulation level;
Aluminum-Silicon alloy heat exchanger, patented Saunier Duval
Class 5 NOx;
Display lights
Efficiency up to 107.6 in the 30% partial load regime (40/30)
4 * heating efficiency
High efficiency pump in 2 stages;
E-BUS connection
SemiaCONDENS is equipped with an electronic e-BUS port that allows the connection of a thermostat modulator, in order to benefit from all the advantages and maximum performances that Semia CONDENS can offer.
