High efficiency and performance
The new Logamax plus GB172i wall-mounted gas boiler is more productive and efficient while remaining a high-quality product at an affordable price. Thanks to the WB5 heat exchanger, the output has been increased to 42 kW, and the domestic hot water comfort level meets the 3-star European standard.
This model has an A-class certificate according to the new European ErP certification system and consumes less than 2 W of electricity in standby mode, which is significantly lower than in similar models.
The modulation range of 1:8 ensures high domestic hot water comfort as well as efficient operation during periods of low heating demand between heating seasons.
Modern Buderus heating systems
The high-efficiency heat exchanger, made from an aluminum alloy, is equipped with a wide-range modulating burner. Together with the modern EMS weather-compensated automation system, it ensures maximum comfort and minimal operating costs.
