The Buderus brand has a history of almost 300 years. Rich experience in the production of heating equipment and the constant introduction of new technologies have allowed the German company to create a top-class product — Buderus Logamax Plus GB172i-20KD.

mod

Behind the mirror black glass, which covers the entire front panel of the device, it is not immediately possible to recognize the boiler. It looks more like a stylish cabinet, which is a spectacular element of the interior. By the way, the glass is not afraid of scratches and is easy to clean from dirt. The lower part of the mirror surface folds down to reveal an intuitive control panel. Next to it, a place is allocated for the optional installation of the Logamatic RC300 controller, with which the functionality of the boiler is significantly expanded.

Two contours

The boiler is suitable for heating rooms with an area of about 160 square metres and is equipped with a reliable aluminium alloy heat exchanger. The temperature range in the heating circuit can be changed from 35°C to 82°C, and in the hot water system from 40°C to + 60°C. When switching to summer mode, only the DHW circuit remains in operation.

Efficiency

The model received a class "A" according to the European system for assessing the energy efficiency of equipment. In standby mode, the level of power consumed by it is only 2 watts, and under load — 60 watts. At the same time, the efficiency of the boiler is estimated by the highest efficiency (about 109%). From a momentary trip for the device to the store, only its high price tag is holding back. However, it is fully justified by the reliability of all elements of the model and its modern decoration.
