Euroterm nitromiX P28 condensing gas combi boiler

Euroterm nitromiX P28 is a wall hanging modern condensing combi gas boiler. Condensing combi gas boiler main task is to provide the comfort of heating and the preparation of domestic hot water for sanitary and central heating purposes. The economical gas consumption of the condensing boiler and the extremely quiet heating operation combined with the small size are its main advantages.

Easy and convenient access to the interior of the gas boiler makes the maintenance work unobstructed and shows a well-thought-out design, This makes the selection of the installation location of the gas boiler independent or not limited by service requirements. Lightweight (slightly over 32kg) condensing gas boiler allows free installation in sensitive areas such as gypsum board.

Very high efficiency 107.5% of the Euroterm nitromiX combi gas furnace has been achieved thanks to a condensing technology that reduces gas consumption by up to 30%. An important aspect is the wide range of power modulation of the gas boiler (the power range is 8,7-26,3 kW), while the excellent parameters at lower power output result in warm water available almost immediately. Thanks to the efficient heat exchanger used. High efficiency of 107% was obtained through the Ecodens technology (heat recovery from exhaust gas) which positively affects the economy of gas consumption.

Also worth mentioning is the possibility of controlling the gas boiler through the room controller. Summer or winter operation mode. Frost protection or overheating protection.
