The entire range of Elnur boilers can be used with hot water radiators or with radiant floor heating, with room or programmable thermostats, and unlike other boilers, they do not require yearly maintenance or safety inspections.

All the components required for the operation and installation are supplied with the boiler. Installations do not require venting or gas outlets which may compromise the insulation of your home.

These electronic boilers from Elnur are completely silent thanks to their TRIAC-based technology. Moreover, they have a modulating operation which, combined with a good exterior programmable thermostat (see accessories), adapts the heating power to the needs of the system, achieving maximum energy efficiency and a considerable saving in consumption.

The maximum power can be limited to any of the modulation levels. With the CM15 this range is from 15kW down to 3kW

The different temperature, flow and consumption sensors ensure a safe and reliable operation.

The digital display constantly shows the temperature of the circulating heating water.
Adjustment of the heating is made easier by using individual keys to increase or decrease the temperature.
You can disconnect the heating system in summer and both keypads can be locked to prevent any changes.
The electronic control of the circulation pump prevents blockage during long periods of inactivity.
