Connecting an infrared heater through the thermostat

Many people are concerned about the issue of reducing electricity consumption. One possible solution to this problem is to use infrared heaters. These devices have bulbs made of sand, which retain heat even after the equipment is turned off for a long time. However, not everyone is aware that by adding a thermostat to a regular infrared heater, even greater energy savings can be achieved. Connecting an infrared heater to a thermostat is a simple task that can be done by individuals without the need for a professional’s assistance.

What is a thermostat

• Devices with a manual mechanism;
• Electronic devices.

A mechanical temperature regulator is a small box-like device that contains:

1. A regulator that enables you to set and adjust the desired temperature.
2. An on/off button.
3. An LED indicator, usually green when the device is operational.

Mechanical devices are relatively easy to use as they can be operated manually. Certain models come with a display that indicates both the set temperature and the current temperature in the room. These models are naturally priced a bit higher.

On the other hand, electronic thermostats possess a more intricate design. They are equipped with a remote control, LCD display, and a mechanism for precise adjustments. These devices are more efficient but also come with a significantly higher price tag.

Installing the thermostat

In order to properly install an infrared quartz heater and thermoregulator, there are several important considerations to keep in mind:

1. The device should be securely mounted on the wall.
2. It is essential to install the device at a minimum height of 1.5 meters from the floor.
3. Avoid covering the thermoregulator with curtains, carpets, or furniture to ensure unobstructed access.
4. Each room should have only one temperature controller.

Wiring diagram

First of all, let’s establish that the infrared heater can be connected to the electric network either through a socket (usually) or directly through the automat located in the switchboard.

The thermoregulator should be installed between the heater and the circuit breaker.

We will explore two connection schemes.

Standard

Before beginning, it is essential to have a clear understanding of the controller’s capabilities. For instance, a standard temperature controller has the ability to simultaneously operate multiple IR heaters. The number of heaters that can be connected actually depends on their individual power requirements.

A single thermostat has a capacity of 3 kW. This is typically sufficient to control up to 3 heaters, which are commonly found in both apartments and private residences.

Typically, most controllers are equipped with 4 terminals: two for the input (phase and neutral) and two for the output.

If two or three infrared heaters need to be connected simultaneously, the initial steps of the procedure stay the same. The thermostat is connected in the exact same manner. However, if two heaters are being installed, four wires need to be run from the output terminals, and six wires if there are three heaters. This means two cables for each heater. This results in a parallel connection.

Additionally, you have the option to use a scheme with a serial connection. In this case, the wires will go from the thermostat to the first heater, and then from the first heater to the second, and so on.

Using a magnetic starter

This approach is more preferable when you require to link multiple infrared heaters or a single industrial unit.

This technique entails the incorporation of an extra apparatus – a magnetic starter. It serves as a switch that belongs to the category of electromagnetic contactors. It enables the management of high-capacity loads generated by alternating or direct current.

The primary objective of a magnetic starter is to enable repeated activation and deactivation of power electrical circuits.

There are numerous connection schemes in which this switching device is utilized, but we will focus on one. The initial steps of the process remain the same, connecting the automaton and thermostat as discussed earlier. However, instead of running two cables from the thermostat to the IR heater, they are directed to the magnetic starter, and then to the heater.

Conclusion

The procedure for connecting the IR heater is not overly complicated, and the same goes for its installation. However, if your familiarity with concepts like three-core copper cable, indicator screwdriver, phase, and zero is lacking due to your focus on more avian matters during physics class, it would be wise not to disregard the assistance of professionals. The well-being of both you and your family is at risk.
