How to choose a heater for home and apartment
In the fall, the room becomes cool. And if you have already managed to hit a strong winter frost, then it's time to get a heater. But how to determine among the many oil, convection and infrared devices that produce heat? Further discussion will be devoted to the choice of a heater for the house and apartment.
Scope and principle of operation
There are 3 types of heating devices on the market:
- Convection - mixes heated air with cold.
- Infrared - heats directly the walls, floor and things, but not the air in the apartment.
- Oil cooler - works on the principle of the battery. Sometimes a fan is inserted into them, then the air flow can be directed to the right place.
Oil heater
The time of appearance of oil heating devices is the end of the last century. Then they were popular and economical. Externally, the device looks like a cast iron battery, but is filled with mineral oil. For its heating is responsible Teng, powered by electric current.
The oil heater works thanks to the convection principle. To heat an area of 10 m2. (if there is a standard ceiling height of 2.7 m), a heater with a power of 1 kW is required. A device equipped with a fan heats the room faster.
The main advantages of the oil heater:
- affordable price;
- long continuous period of work;
- mobility.
Disadvantages:
- long heating period;
- impressive size;
- hot body.
Convection heater
At the heart of the work of such a device - convection. Cold air flows through the slots below, then the already heated and lighter air leaves the heater and is directed upwards. The rate of air heating depends on the area of the heating elements.
A convector heater is not as inertial as an oil heater. It heats up in a couple of minutes, because the coolant is air, not oil.
Benefits:
- reasonable price;
- moderate body heat;
- silent operation;
- overheating protection.
Disadvantages:
- small warm-up location;
- there is no built-in fan, the air in the room heats up longer.
Fan heater
This device is inexpensive but noisy. The dimensions of the fan heater depend on the size of the blades. Air heating is provided by a metal spiral or ceramic heating element.
Main advantages:
- low cost;
- profitability;
- automatic shutdown (in some models);
- ease and mobility.
Negative characteristics:
- high noise level;
- short time of continuous work;
- dries the air.
Infrared heater
Radiation of infrared waves provides a halogen, carbon or quartz lamp. This spectrum is not available to our eyes, the operation of the device for a person is invisible. Heated not air mass, and objects in the room. Devices are floor, wall and ceiling. For the installation is suitable not only a room, but also a terrace with a balcony.
Main advantages:
- noiselessness;
- uniform and fast heating of the room.
Negative sides:
- high cost;
- the risk of overheating, since the infrared beam is very warm subject in the radiation zone.
How when choosing a heater is not wrong and correctly decide which one is better?
5 basic rules when choosing:
- Do not believe the seller that it is this beautiful model of the heater does not dry the air, but this cheap representative will burn oxygen. Both the first and second comments are advertising nonsense - only the heat generator is very dry.
- Consider the area of the room for which you choose a heater.
- Remember the elementary safety rules: for a child's room, take a device equipped with a protective casing (so that the child does not get burned), use an infrared device in a dusty room, and choose a device for the bathroom, the case of which is protected from water.
- On the heater must be stamped certificate.
- A well-known brand and reliable manufacturer is a guarantee of the quality of the goods. Here you need to be careful not to purchase a fake.
