Wall-mounted infrared heaters with thermostat

Wall-mounted infrared heaters are comparable to automatically controlled sun. Devices with thermostat profitable, work on a given program, even in the absence of the owner. Difficulty in choosing a place to install a thermostat - devices affect a limited space.

About infrared heaters

A resident of the Moscow region, the owner of her own cottage, recently transferred the house to heat with infrared heaters with thermostats:

When I leave home in the winter, I leave the program to maintain 10-15 ° C.This is enough to bring the air temperature in the premises to 20 ºС for a quarter of an hour upon return. While dressing up and dressing in home clothes, the cottage is already happy with the summer heat. In the long absence, it is enough to set the program at 5 ºС to prevent the premises from freezing. The thermostat will not allow the mark to fall below zero, respectively, the central water supply does not freeze.

The owner of a wooden house does not use other heating methods, only infrared heaters with a thermostat. There are enough devices to keep warm in the harsh Russian winter.

Without thinking twice, the experts conducted a study. Two types of heaters were installed in two equivalent rooms of one private cottage:

  1. Infrared ceiling heater with thermostat.
  2. Household oil cooler.

Both heaters exhibit the same power and should, according to the idea, heat the rooms and beds in the center. The infrared heater is suspended above the object of close attention, the oil radiator was installed nearby, on the floor.

In both rooms, one person temporarily lived, the test subject, who was occasionally visited by a group of researchers with an electronic contactless thermometer to understand what was happening during the operation of the instruments.

The infrared heater coped with the task quickly, heating the air to 20 degrees, then turned out to be automatically turned off by the thermostat. Thermometer recorded bed temperature at 27 ºС.An oil radiator of equivalent power looked much more modest, eventually heating the air. However, the temperature of the bed remained at 17 ºС.The author prefers a cold bed and warm air, but most, as you know, thinks otherwise. We add that the oil heater has a thermostat, both devices do not need human control.

By the way, infrared devices spend less energy, because the efficiency is higher, reaching an unprecedented value of 95%.

The principle of operation of thermostats

So, both devices from the experience are equipped with thermostats. In the oil heater, the element measured the temperature near the radiator. In the case of an infrared lamp, the principle is different. The thermostat is supplied in a separate enclosure and measures the temperature at the installation point. The infrared heater hangs on the ceiling, and the temperature is measured, say, near the door. It makes a big difference.

Consider moments that are not so obvious at first sight:

  1. Everyone understands that oil heaters do not support anti-freezing temperature in a house. It is simply meaningless, the devices are not endowed with great flexibility in the sense of thermal conditions. In this sense, the thermostat of the infrared heater is much more accurate, able to perform complex work.
  2. It is simply dangerous to leave a bunch of oil heaters in the house, fire is possible. This comes from the fact: the radiator heats up, and then transfers heat to the air. This is potentially dangerous, electrical wires are stretched inside the device. The wall-mounted infrared heater works differently. A discharge occurs inside the lamp, energy is carried away by radiation quanta. Actually the device is not heated. Heat is received not by air, but by surrounding objects. If you hang the infrared heater on the ceiling, the floor temperature rises.

This looks amazing. Especially in industrial environments. The infrared heater hangs high, and the body feels warm, as if the sun is shining overhead. Energy is transmitted not by convection of air masses, but by radiation, to which the distance is not an obstacle.

Let's enter the third item in the previous list. The efficiency of infrared heaters is higher than that of oil:

  1. The money spent on company accounts will be less.
  2. Electrics in the house is not so hot.

In the light of the above, it turns out that infrared heaters have proven the convenience of the method of automatic temperature maintenance.

About the device temperature controllers

Temperature controllers are divided into mechanical and electronic. The second is more expensive, equipped with a liquid crystal display, perform a number of additional functions.

Mechanical

The mechanical thermostat looks like a small plastic box with a circular knob to set the temperature. Convenient risks, inscribed in figures, will allow you to easily select a mode. The number 20 is replaced by a bulging large circle. Do not need sharp eyes to find the icon. Trick helps poorly seeing people, will help the average person in the dark.

Inside the device there is a sensitive element that determines the accuracy of the device as a whole. Typical error is half a degree. Not bad at all. The limits of setting changes fall within the range of 5 - 30 degrees. Thermostats for infrared heaters essentially resemble a relay that is triggered when the temperature in the room passes through the limit value. There are input and output contacts, the task of the device is to see the closure and opening of the circuit between them.

Mechanical principle of operation, no external power required. The trigger limit of the sensitive element is regulated by the handle.

It is important to pay attention to the maximum operating power of the device. A thermostat for an infrared heater is able to regulate the supply of electricity to a number of lines. The regulator is permissible to install only one per room or house. Example: thermostat power 2 kW, power of four heaters is in the amount of 3.2 kW( 1 + 1 + 0.6 + 0.6).Obviously, two regulators will suffice, each will start to control a pair of infrared emitters.

Electronic

There are a lot of temperature sensors on the market.

For example, we will meet thermostats with an infrared sensitive element. As is known, heated bodies emit electromagnetic waves( devices operate on the subject of the article based on the phenomenon), they are perceived. Measured radiation frequency, directly dependent on temperature. Thus, the thermostat recognizes when it is time to stop the supply of current to infrared heaters.

Electronics is characterized by a liquid crystal display and visibility, which allows you to set a program, for example, a week ahead by day and time. The fact that on mechanical models get ready to do manually, here is done automatically. It is convenient, it is possible to start heating a quarter of an hour before coming home. What is basically impossible for mechanical thermostats.

The next step in evolution is seeing the devices of the class “Smart Home”.The thermostat communicates with the control center at a frequency above 800 MHz, and is capable of controlling a myriad of heating devices. There is no need to remind that the commands from the smartphone will help to start heating the rooms at the right time. This option is convenient if in no hurry there was no time to turn off the heating. No matter where the owner is, the devices will obey.

Many devices are universal. Connecting the thermostat to an infrared heater may later be replaced by a system with a heated floor without the hassle. Sense in the correct setup of sensors for measurement. Thermostats should not be exposed to direct sunlight, drafts. Do not place appliances on the outer wall of the room.

Smart devices are mostly equipped with self-monitoring functions. If the sensor fails, the heating devices are switched to the 30% activity mode. This does not allow the house to cool completely and guarantees the absence of overheating of the premises.

It is worth adding that electronic thermostats more precisely mechanical at times.

Conclusion of

It is not always easy to distinguish electronic thermostats from mechanical ones at first sight with mechanical ones, the appearance can be the same. The differences lie inside. The first requires current energy to work, the second serves as a switch, does not depend on the operation mode of the local network. Connecting an infrared heater through a thermostat will allow the branch to work on maintaining climate in the absence.

Some people like it all the time, coming home, manually changing the settings, others prefer electronics, which do everything themselves. The price difference is small. Choose according to your taste.
