Gas condensing boiler Integra Comfort 20 kW combi
INTEGRA COMFORT
INTEGRA COMFORT is a modern, gas-fired, wall-mounted condensing boiler with a built-in 50-liter storage tank. A complete heating system in an elegant design, it provides reliable hot water production thanks to the efficient storage tank. The expansion tank for central heating and domestic hot water is easily accessible after removing the cover. The 50-liter storage tank guarantees instant access to hot water upon turning on the tap. Furthermore, the high-output coil ensures instant water heating in the tank. - Internet control - room temperature management via smartphone or tablet using the Termet Comfort System package
