The heater is a device that can emit warm air. It is small in size, easy to move, and heats up quickly. It is used for both household and industrial use. The power of household heaters is relatively small. The heater with waterproof function can also be used for bathroom heating. , is a common heating equipment in winter. So, what is the principle of the heater? How many types of heaters are there? How to choose a home heater? Let’s take a look at heater selection, installation, cleaning, maintenance and other related content. Introduction to Heater What is Heater
Heater is a device that can emit warm air. It is a combined unit composed of a fan, a motor and an air heater. . There are suitable for home heating, bathroom heating, low power, energy saving, can ensure the rapid rise of indoor temperature, small size, convenient and flexible use. There are also heaters that are suitable for heating of various large factories, restaurants, cinemas and other large spaces, and can increase the indoor temperature by blowing air flow in a short time.
The principle of the heater
The working principle of the electric heater is to make the air circulate. The heater is mainly composed of an air heater and a fan, as well as an air inlet and an air outlet. The air inlet sucks in cold air. , then through the air heater, and then the fan sends out warm air, so that the indoor air temperature can be adjusted.
Does the heater have radiation?
Now many electrical appliances have radiation, and the heater has electromagnetic radiation, which is more harmful to pregnant women and children, but don’t worry too much. The distance of more than meters, so the harm of electromagnetic radiation to the human body is minimal.
Types of heaters
1. Fuel heaters: Generally, light oil such as diesel or kerosene is used, and the fuel is directly atomized by high pressure and transported to the combustion chamber, and then sent to the combustion chamber by the ignition device. Ignite a form of heating the heat exchanger, and the heat is blown out by cold air in the form of hot air.
2. Electric heater: Easy to use, no additional equipment is required, and the use cost is relatively high. Others require pipes or boilers to achieve, although the use cost is low, but the overall cost is high.
3. Gas heater: It uses liquefied petroleum gas as fuel (commonly known as gas), because the use of this machine requires enough oxygen, so it must be used outdoors or with certain A good amount of ventilation in the room. Installation should comply with valid national regulations including technical regulations and fire regulations, and the cost of use is low.
4. Plumbing heater: It requires a boiler and a hot water pipeline, which has the lowest efficiency, lower operating cost and higher overall cost.
In addition, from the perspective of the general environment, it can be divided into household and industrial use; heaters are divided into three types: horizontal blower, top blower, and floor heater according to their shape and structure.
Advantages and disadvantages of heaters Advantages of heaters
Pictures of heaters
1. The effect of household heaters is very good, the heat is concentrated, the heat dissipation area is large, and the heat Efficient. Infrared heating, high heat conversion efficiency, energy saving and power saving, and quickly dispel the cold. Two different heating methods can be freely selected to meet different thermal needs.
2. The appearance is fashionable and beautiful, and it is necessary for home in winter. The power is adjustable, and the heat can be selected at will; the precise parabolic energy gathering technology has high thermal efficiency; the infrared heating heats up quickly, and the heating distance is long.
3. High-quality heating components are used to ensure the service life; the heating body has excellent wide-spectrum characteristics, which has the effect of health care and physiotherapy; the whole adopts double protection design to ensure safety.
Disadvantages of heaters
Due to the different heating elements used in heaters, their prices vary. While the multi-functional heater provides more convenience for people, it also directly leads to the increase in the cost of the machine.
Which heater and air conditioner save electricity
1. Heating power of heater and air conditioner
Heater: The heating power of the heater is 1800W, which produces 1800W heat.
Air conditioner: 1.5P air conditioner heating power 1200W + auxiliary electric heating 800W=2000W, producing 1200*3+800*1=4400W of heat.
2. Applicable power of heaters and air conditioners (take the needs of a 20-square-meter room as an example)
Heaters: heaters with a power of 1800W.
Air conditioner: suitable for 2P air conditioner, heating power 1800W + auxiliary electric heating power 1500W=3300W.
3. Energy efficiency ratio of heater and air conditioner
Heater: 1:1, consumes 1000 watts of electricity and produces 1000 watts of heat.
Air conditioner: 1:3, consumes 1000 watts of electricity and produces 3000 watts of heat.
It can be seen that compared with air conditioners, heaters are more energy-efficient. I suggest choosing air conditioners to save electricity, preferably inverter air conditioners; heaters are more suitable for heating bathroom spaces.
The difference between the heater and the electric heater
1. The difference in heating principle
The electric heater is the heat transfer oil around the electric heating tube that is heated and rises to the cavity. In the upper part of the body, the convection circulates along the heat pipe or the heat sink, and the heat is radiated out through the surface of the cavity wall, thereby heating the space environment. The heat transfer oil cooled by the air descends around the electric heating pipe and is heated again, starting a new cycle. The principle is different from that of the heater.
2. Differences in heating temperature
The surface temperature of the electric oil heater is relatively low, generally not exceeding 85℃, and it will not cause burns even if it touches the human body. Generally speaking, the maximum temperature of the heater is about 40°C, which includes four parts: heating, blowing, temperature and blowing control, and protection.
3. Differences in heating speed
The electric oil heater needs to be preheated, and the surrounding temperature will gradually increase. As soon as the heater is turned on, there is basically hot air blowing out.
4. Difference in comfort level
The electric oil heater heats up slowly, but the whole room is heated evenly, and it has little effect on the room humidity, so it feels more comfortable. The heater needs to be blowing against it to get warm, and it is easy to dry mouth after blowing for a long time.
5. Power difference
The power of the electric oil heater is too large, and the households with small capacity or low voltage of the electric meter cannot use it. The power of the power heater is generally relatively small, and the noise when starting up is a headache.
6. Differences in suitable places
The heat radiated by the electric oil heater is relatively large, and it is suitable for places such as bedrooms, living rooms and offices. The fan heater has soft air supply and fast heating, so it can only be used in a small area. In addition, PTC components are generally waterproof, so they are more suitable for use in the bathroom.
How to choose a home heater
1. Distinguish the types and buy as needed
Unlike electric heaters that rely on radiation to dissipate heat, heaters are characterized by Forced convection heating to quickly raise the room temperature. In addition, compared with electric heaters, heaters generally have the advantages of small size and light weight, and are especially suitable for heating in smaller rooms. There is also a class of heaters with a unique splash-proof structure that can be used in the bathroom.
2. Various styles, safety first
There are desktop, vertical and wall-mounted heaters. Desktop heaters are small and exquisite, and vertical heaters The fan has smooth lines, and the wall-mounted heater saves space. However, when purchasing heaters, safety should also be given top priority, such as whether the machine has protection devices to prevent overheating and overcurrent, and whether it has the function of dumping and power-off, especially bathroom heaters, which must be waterproof, The characteristics of waterproof splash, so you should carefully check whether there is a waterproof mark on the machine.
3. Look for big brands and manufacturers
Generally, for the selection of household heaters, we also need to look for big brands and manufacturers. Because some off-brand products flood the market, most of them imitate brand-name products in shape and confuse consumers. Therefore, the editor of Buying.com recommends that users pay attention to the brand inspection when purchasing, otherwise it is easy to be deceived.
Bathroom heater installation
1. Do not install or place the bathroom heater too close to the bathtub, washbasin or shower, and try to avoid spraying water directly on the bathroom heater when bathing. The location of the electrical outlet should not be exposed to water splashes or sprays. Bathroom heaters must not be placed directly under an electrical outlet.
2. The heater should be installed in a dry indoor place that can avoid rain and snow, and avoid moisture; second, it should be well ventilated, and it should not be used in a sealed box; third, the air inlet should not be blocked, and the air outlet should be wrapped with For the piping connection of the heat insulating material, pay attention that the piping should not be too long, too thin, bent or bent too much. Finally, keep away from flammable, explosive and other dangerous items and gases.
3. If the air-conditioning heater is installed too high, the heat will be concentrated at the top of the room, and the temperature felt by the human body is lower than the actual temperature, which will lead to unnecessary energy waste and increase the user’s heating costs. . In addition, due to the different lighting conditions on the sunny side and the shaded side of the bedroom, the number of air-conditioning heaters required is also different when the area is the same.
4. When the heater is installed, the air outlet must be inclined upwards by 15°, and the air outlet must be inclined at 10° downward, and the left and right inclination of the body should be used within the range of 15°; The content of substances, dust content and other solid impurities is not more than 100mg/m3.
How to use the heater
1. Do not place the heater next to the power socket, and do not touch some heating elements inside the heater to avoid accidents.
2. During the use of the heater, do not cover the heater with anything, which will cause the body to overheat and may damage the internal parts.
3. Avoid using heaters in humid or watery places. Although the waterproof performance of heaters is getting better and better, everything is just in case, so it is better to pay a little attention.
4. Do not use the heater near inflammable and explosive items (such as curtains, door curtains, textiles) to avoid fire. It is also best to keep a safe distance of more than 0.5 meters from inflammable and explosive items during storage.
How to clean the dust of the heater
1. How to clean the dust of the heater is more concerned by everyone. The housing of the heater is easy to get dirty, and it is often wiped with a sponge. Be careful not to let water enter the appliance, do not splash water on the heater, and do not use solvents such as gasoline, toluene, etc. to clean items to protect the casing.
2. When cleaning the heater, first turn off the power switch, and then start cleaning after it has completely cooled down. Before cleaning, you need to remove the bulb, wipe the lamp head with a dye cloth soaked in warm water, and then dip in the detergent to focus on cleaning the dirt, and finally install the bulb back and test it with electricity.
3. Clean the power cord and plug, if the dirt is stubborn, wipe it with water and detergent, and finally dry it with a dry cloth.
4. When you want to store the electric heater, first let it cool down and keep it dry, then cover the box with a dry plastic bag, and store it in a dry and ventilated place.
Common fault repair of heater The electrical appliance does not heat up, only the ventilation fan is working
Troubleshooting:The switch is not placed on the heating setting; the temperature regulator operates; the non-self-resetting cut-off operation.
Solution: Adjust the position of the switch on the heat setting; turn the thermostat and listen for a sound to turn it on or off. If there is no click, the thermostat is not damaged. When the appliance cools down, the electric heater will automatically turn on; disconnect the power supply, insert the lever directly into the reset hole on the control panel, press the reset button, and connect the circuit.
Fan heater heating element glowing
Troubleshooting: The heating element glowing may be caused by the input voltage is too high or too low; the air entering the grille is blocked, etc.
Solution: Use the relevant operating instructions correctly; keep the heater away from objects like curtains, plastic bags, paper, etc. that tend to cover the air inlet.
The heater does not work after being powered on
Troubleshooting: Check whether the power plug of the machine is plugged in properly, whether the safety switch is in good contact, whether the internal lead of the machine is unsoldered or falling off, and whether the fuse is Overheating and burnout, etc., otherwise all the machines will not work, that is, the upper and lower tubes will not light up, and the fan motor will not work.
Solution: Unplug, check the connection between the plug and outlet, and then connect again. Insert the plug into the appropriate socket.
