The Elnur CMX15P Electric Heating & DHW Hot Water Boiler with adjustable 3kW to 15kW Outputs offers you the opportunity to enjoy the safety and convenience of electric energy.

Please contact us for Special Pricing and Offers on this range.

They are the ideal option when a totally safe and efficient central heating system is required in both 3 x 400V+N~ and 230V~. The boiler is compatible for one or three phases by using the bridge connection included) in the terminal block.

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.  The CMX15P in this range is from 15kW down to 2kW.

The different temperature, flow and consumption sensors ensure a safe and reliable operation. The stainless steel cylinder in the CMX models guarantees a long, corrosion-free life, reducing the need for maintenance and periodic replacement of anodes. The keys are easy to clean and highly intuitive when used.

The digital display constantly shows the temperature of the circulating heating water and of the Domestic Hot Water (DHW) tank.

Adjustment of the heating and DHW 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.

Where can an Electric Boiler be used?
An electric boiler can replace any other small to medium size boiler in the home, and are known to be light, small and compact, often completely silent and, of course, boasting the main benefit of a low running cost due to the price of electricity in comparison to oil or gas.

It is most common to need an electric powered boiler in rural areas where oil or gas access may not be available, but also some new housing projects or flats are being fitted with electric boilers by choice due to its environmental and cost benefits.

Comes with a 2 Year Manufacturer's Warranty.
