Outdated Product
Powerful double-circuit heating gas boiler for wall mounting. It has an impressive useful thermal power of 25.8 kW, which allows it to confidently cope with heating and hot water supply for a detached house or a large city apartment with a total area of up to 205 m2. Equipped with a closed-type combustion chamber with outdoor air intake through a coaxial chimney and a forced flue gas removal system. This design solution allows you to mount the Chaffoteaux PIGMA ULTRA 25 FF boiler directly in residential areas. Equipped with durable and efficient heat exchangers made of high quality stainless steel. It can work both with a classic heating system equipped with wall-mounted radiators, and with underfloor heating systems that require a lower coolant temperature (from 30 to 45 °C). Equipped wit...h an electronic microprocessor control system and an LCD screen, it allows you to connect both a simple remote room thermostat and more advanced programmable weeks. Provides high efficiency of 93.7% and decent performance of the hot water circuit. Able to give 9.5 liters of water per minute, provided it is heated at 35 °C. It has a full set of protections for gas, temperature, pressure, as well as a system that prevents the coolant from freezing.
