ePlus 9kW electric boiler

ePlus, range of electric boilers (with nominal heat output of 6, 9, 12, 18 and 24 kW) is designed for installation in smaller premises as a primary as well as secondary heat source. Today they are frequently used for heating up domestic hot water in accumulator tanks connected to the heat exchanger of the boiler. The El-Cm ePlus is equipped with a circulation pump, expansion vessel, the most modern modulating digital controller and appropriate safety elements. Of modern design, they can be installed anywhere in a house because of their absolutely noiseless operation and because they do not need to be connected to a chimney. The wide application of modern technologies and the quality of the material used as well as thoroughly tested operation, which include a modulating activating of the electric heaters, to prevent electric surges on the power supply, make these boilers safe and reliable.

• Comfort settings and control through multifunctional LCD 
• High efficiency up to 99%
• Small size 
• Dynamics of heating rod flow (PI regulation), energy savings 
• do not allow water overheating above the set temperature
• function even without the weather-compensated control
• Heating rods rotation increases the life of the boiler
• Continuous power regulation as from 2,5kW with switching of heating rods gradually - prolonged  boiler service life.
