Buderus Logamax plus GB072-24K, Wall mounted condensing boiler
Buderus Logamax Plus GB072-24K is a productive and reliable condensing gas boiler designed specifically for heating small households for 1-2 families. The condensing gas boiler is equipped with an efficient pre-mixed stainless steel burner. The net efficiency is 97.5%, and the utilization factor, taking into account the heat of condensation, reaches 109%.
Buderus has equipped this gas boiler with an intelligent control panel with a BC20 multifunctional module with an integrated EMS bus (for connecting, for example, a Logamatic RC or Logamatic 4000 control panel). The service menu allows you to conveniently set up and control various functions. The large display with textual and graphic indication makes the operation even easier and more comfortable. The controller is initially set to hot water priority.
Advantages of the condensing boiler Buderus Logamax Plus GB072-24K
- designed for installation in closed heating and hot water heating systems.
- Intelligent electronic system for automatic control of the boiler. The formation and maintenance of the flame is controlled throughout the heating cycle;
- The ultra-economical burner has the possibility of modulating combustion control in the power range of 21-100%. Allows you to reduce fuel consumption and increase the efficiency of the entire system, while extending the life of the boiler;
- Equipped with a three-stage circulation pump and a full-fledged safety group, including a safety valve (3 Bar);
- Built-in 12 l membrane expansion tank to adapt the boiler to a heating system with a large water content;
- equipped with a built-in heating circuit pump;
- low emission of harmful substances - the content of nitrogen oxides in flue gases is less than 60 mg/kWh;
- It is allowed to operate the unit on liquefied gas with the additional installation of a special conversion kit;
- it is possible to connect concentric pipes with a diameter of 60/100, 80/125 mm or to switch to two separate pipes with a diameter of 80 mm for flue gas exhaust/combustion air supply;
- The operation of the boiler is characterized by a minimum level of noise and low emissions into the environment. Combustion is characterized by stability and cleanliness, and the temperature of the flue gases is only 3K higher than the corresponding parameter of the return line of the heating network.
The Buderus Logamax GB072-24K condensing boiler is controlled by EMS automation. It is possible to operate in weather-dependent mode, regulate the operation of the burner according to outdoor or room temperature thanks to modern Buderus Logamatic control systems for wall-mounted boilers. The panel displays an indication of errors and malfunctions.
Installation features of the condensing boiler Buderus Logamax Plus GB072-24K
The Logamax Plus GB072-24K condensing gas boiler is designed for wall installation, so before installation, make sure that the wall can support the weight of the filled device. A number of basic recommendations should be taken into account:
- the boiler must be connected to the heating system through shut-off valves and detachable fittings;
- on the return line of the heating circuit, it is necessary to provide for the installation of a dirt filter;
- Buderus GB072-24K uses the heat of condensation in its work. For this reason, the installation of condensate neutralization devices is required;
- if pipelines without an oxygen barrier are used for heating the object, a heat exchanger must be provided in front of the Buderus Logamax Plus GB072-24K"
