When the heating season begins, the owners of apartments and country houses prefer autonomous heating sources: electric fireplaces, oil heaters or gas convectors. Not so long ago, a quartz infrared heater appeared on the market, which can lure buyers to its side — it does not overload the network so much, it is fireproof and consumes electricity more economically than others. Due to these qualities, the device will serve the owners longer, will effectively warm up the room and keep the heat for a long time when turned off.
Device and principle of operation
The device contains a heating element — a vacuum flask made of quartz mineral with a spiral inside, which is made of tungsten. The principle of operation of the heater is that the tungsten coil heats up under the influence of current and emits infrared rays. The rays do not heat the air, but the floor, walls, ceiling and objects that are in their path, and these objects already give off heat to the entire room. And also the device is equipped with a reflector (reflector) of rays, due to which heat is dissipated more evenly. Reflectors are made of stainless steel and in addition to reflecting the rays, they perform the function of protecting the heater body. Some models of devices are equipped with a thermostat.
The main advantage of a quartz infrared heater is its safety — a hot spiral and a flask are protected by a reflector and an additional grid. Other benefits include:
- high efficiency factor;
- saving electricity;
- does not pollute or dry the air;
- does not burn oxygen;
- long service life;
- wide price range;
- small size of the device.
The heater quickly warms up a small area. It will not cope with large rooms so quickly, but if necessary, the problem will be solved by installing an additional device. And also, buyers opt for a quartz infrared heater, because being under infrared rays has the same relaxing effect as being under the sun’s rays.
Disadvantages of the heater
First of all, the disadvantage is that it heats only those objects that are within the reach of its rays. The problem can be solved by purchasing an additional device, but it is more reasonable to consider options for other heating devices. The disadvantages also include:
- Average level of safety when using; despite the fact that hot parts are protected, curious children and animals can, if desired, get into them and injure themselves.
- The device is not suitable for high-quality heating of a large apartment, cottages and other large areas.
- Damaged heating elements (coil and bulb) cannot be repaired.
- Not too solid appearance may also seem like a disadvantage for some buyers.
Varieties of quartz infrared heaters
Models of devices differ in the number of heating elements inside. They come with one, two or three flasks inside — the quantity affects the quality and area of u200bu200bheating and the price of the device. In addition, they differ in the method of attachment:
And in appearance:
There are also monolithic models of quartz heaters.
Monolithic quartz heaters
A monolithic quartz heater differs from an infrared heater primarily in its appearance and principle of operation. The monolithic type of device is presented in the form of a rectangular plate, which is made of melted quartz. A stainless steel spiral is installed inside the plate. It has all the advantages and disadvantages of an infrared quartz heater, and in addition, the device can still work when the electricity is turned off.
How to choose a quartz heater
The information provided in the article should be enough to understand how to choose a quartz infrared heater and whether it is well suited for the room to be heated. But first of all, it is important to know the size of the room or building, since the heater works best in small buildings or as an additional source of heat to the existing central heating in larger rooms.
If one device is not enough for heating and you plan to buy another one, you need to calculate whether this will save energy. For this, there is a formula that says that for every 10 m2, 1 kW of energy is spent. The power of quartz infrared heaters starts from 800 watts. If the indicators are not satisfactory, it is worth considering other options for heating devices.
