With the new generation units with soft heat, we now enjoy a level of comfort close to that of central heating. In addition, with a minimum of tools, the installation of an electric heater is simple to achieve.

Install and connect an electric heater

The soft heat is based on the principle of "dry inertia", which uses a resistor coated with a ceramic accumulator material, active cast iron, steatite... This device stores the heat and restores it slowly in a homogeneous way, without drying out the heat. air of the room.
More efficient still, the soft heat produced by the installed model ("Calidou" of Noirot) offers the double advantage of an active cast iron heating core, which provides an enveloping heat, and a radiant facade. This ensures a rapid rise in temperature, by irradiating the surrounding surfaces (walls, floor, furniture...).

Standards to be respected

The installation takes place here replacing a radiant panel that has had its day. The connection box is already in place, the work is facilitated. If there is no dedicated circuit, it must be done first from the distribution board (recessed or exposed line, under molding or PVC baseboard). However, in all cases, the specifications of standard NF C 15-100 must be complied with (see Practical advice on page 60). The device is equipped with an electronic thermostat, accurate to the nearest tenth of a degree, and an onboard programming. S
The various functions (comfort, economy, frost protection...) are complemented by an automatic open window detection. If you forget to stop the heating before airing, the radiator goes to sleep as soon as it detects the temperature drop. Once the window is closed, the heating returns to its initial mode of operation.

Economic management

Like most recent models, the unit is designed to be connected in series with other radiators in the same installation via a pilot wire connected to a centralized programmer.
If the addition of a pilot wire is problematic (in the case of a renovation of an occupied dwelling, for example), it is possible to equip the radiators with receiver modules operating by radio waves or by power line (PLC)..
Centralized management saves up to 25% on the heating bill.
However, given the price per kWh of electricity (and its constant increases), this heating mode is really profitable only with good thermal insulation.

The steps of installing an electric heater

how to install an electric heater

Present the anchor plate on the wall, adjusting it to the level required by the instructions.
The bottom of the radiator must not be less than 15 cm from the ground.

fixing an electric radiator

Mark the fixing points through the perforations: there are 4 or 6 depending on the format of the device.
Drill the wall, put suitable dowels, then screw the backsplash.

connect an electric radiator

Class II, this model of radiator does not need to be connected to the ground.
As it is used alone, we choose here to cut the pilot wire (always black).

connect an electric heater

Make the connection using dominoes respecting the polarities: neutral (blue wire) and phase (red).
Do not connect anything to the ground conductor of the supply circuit.

to pilot an electric radiator

Before suspending your radiator, insert the FP transmitter cassette in its slot. It allows individual or zone control (several devices) of electric heating.

fix an electric heater on its turntable

Lock the radiator cord in the cable outlet and secure it to the junction box.
Present the device by tilting to hang it at the bottom of the stage first.

complete the installation of an electric radiator

Then straighten the radiator and, lifting it slightly, hang its upper part.
After checking the position, operate the locks on the anchor plate.

configure his electric heater

All that remains is to turn on the power and configure the on-board programmer. This involves first calibrating his thermometer according to the ambient temperature.

• Basic precaution, turn off the power before working on the electrical system. If you just turn off the line, check with a tester that the electricity is no longer coming out of the wires.
• The latest evolution of the standard NF C 15-100 sets four maximum power levels for an electrical heating circuit: 3,500, 4,500, 5,750 and 7,250 W. The wiring section and the rating of the division circuit breaker increase accordingly: 1.5 mm2/ 16A, 2.5mm2 / 20A, 4mm2 / 25A and 6mm2/ 32 A. Beyond 7,250 W of installed capacity, the installation of a new circuit is necessary.

Hang an electric heater

How to suspend an electric radiator of 80 kg on a plasterboard doubling on metal framework without one of the pegs tearing?
Christian Pessey's answer:
Expansion anchors in plasterboard withstand heavy loads.
When a fixture gives way, there are two reasons for this: either the fins are too short, or the ankle is too tight and compresses the plasterboard too much.
To avoid this, choose the larger model so that when folded on the back of the plate, the fins are as long as possible to better distribute the load around the hole.
Operate the pliers until you feel the seating resistance of the ankle that must form a triangle on the back of the plate.
