Electric dual-function boiler EKD.M3-12/16/20/24 10.1.02.009.04

Electric dual-function boiler – comfort and savings in one device

The EKD.M3 dual-function electric boiler is a comprehensive heating solution, integrating a central heating boiler with weather control, a 130-liter domestic hot water tank, diaphragm expansion vessels for CH and DHW, and a circulation pump into a single housing. It is an ideal proposition for people looking for a convenient and efficient way to heat their home and ensure access to domestic hot water.

Functionality and efficiency

The device offers a wide power range (from 12 to 24 kW), allowing it to be adapted to individual needs and the size of the heating installation. The weather controller automatically adjusts the boiler's operation to changing weather conditions, ensuring optimal energy consumption and thermal comfort. The ability to program room temperature on a daily and weekly basis further increases energy efficiency and allows the device to be adapted to the rhythm of life of the household.

The boiler has DHW priority, which means that when there is a demand for domestic hot water, the boiler automatically switches to water heating mode, ensuring its constant availability. Additionally, the ability to cooperate with a CH buffer tank (using appropriate modules) allows for the accumulation of heat during favorable energy tariffs, which translates into further savings.

Construction and installation

The compact design of the EKD.M3 boiler makes installation easier and saves valuable space in the boiler room. The device is equipped with a CH safety valve (3 bar) and a DHW safety valve (6 bar), as well as a pressure gauge allowing control of the pressure in the installation. The built-in expansion vessel with a capacity of 12 liters stabilizes the pressure in the heating system, and the presence of a thermometer allows for continuous monitoring of the water temperature. The boiler is adapted to work with a closed system and has overheating protection thanks to a temperature limiter.
