You might be wondering why these heaters are called space heaters. It is solely because they are relatively compact. Mobile heating devices are generally used when the central heating criteria are inefficient. All in all, if just a single room requires heating on a freezing night, space heaters are the best and more economical solution. These heaters are available in multiple models and can operate with fossil fuels such as propane, electricity, or kerosene.
Space heaters run through convection or radiation heating. Radiant heaters release electromagnetic radiation that directly warms objects in the room, which is very efficient. These types of heaters are best only when required to heat a small-sized room for a limited amount of time and when everyone would be near it. In addition, this type of heating can be very effective since it heats the occupant or the individual directly rather than the entire room, which is mostly unnecessary.
Heaters With Their Different Requirements
Which type of room has to be heated and by how much? Whatever type you choose, make sure you select the heating that fits the room you want to heat. If you buy a large space heater, you can be a fire risk, so you must be cautious about it. The temperatures can get pretty high for a small room if you increase the size of the space heater. A list of some available used space heaters are given below:
- Vented Heaters
It is suitable for heating any area where the temperature is not affected by outside heat. However, it is strange that it is designed to be installed only once and on a single wall in a house. The units, known as sealed combustions, take in cold air from the outside environment. And, to be honest, despite its appearance, this process is quite simple and, more importantly, safer to use. Because they use outside air. These sealed units are also very systematically productive.
- Unvented Heaters
Because these types of heaters bring in dangerous by-products such as toxic carbon monoxide (CO), other hazardous oxides such as nitrogen, and many other substances, these space heaters are not very safe to use inside the homes. As if this was not enough, this type of heater also pollutes the air, making it harmful to breathe in.
- Electric Heaters
Electric Heaters are more expensive than combustion heaters. Moreover, these heaters are not provided with air, which can cause them to heat up and thus can be quite risky to use in a non-ventilated house. Even though these heaters do not affect the air quality as the unvented combustion heaters used to do, they pose a risk of igniting a fire if not properly managed. Some space heaters develop a coolant, such as oil to ensure a better provision of heat. The purpose of which is to provide constant heat.
Working Of Convective Heaters
Most of the residential heaters that people use are convection heaters. And there are still two more types in the convective heater: One of them is with a fan to distribute proper heat and one without a fan. These heaters are very efficient in spreading warmth and will apply better if the room is well-insulated.
Warm air needs to circulate in the room for efficiency. That is why convective heaters use a fan to do so. Other than this, the surrounding air directly touches the hot metallic unit, which uses the fan to warm the room faster enough.
The heating unit needs to be filled with oil or water for heat without a fan. The water or the oil needs to be heated before using this heater, and for that reason, this type of heater is not reasonably efficient. However, these heaters stay hot, even after getting switched off because of the heated fluid present inside the compartment.
Fluid-filled heaters sometimes have a lower risk of burning or catching fire than heaters with a fan. However, generally, it is the opposite in most cases.
Working Of Radiant Heater
Many people believe it transmits heat via electromagnetic waves, which are converted to heat when absorbed by a human. This heater enables a person to warm himself without coming into physical contact with the heating source. Furthermore, it quickly warms a non-insulated room, which is a very impressive feature.
The radiant heater’s wires were made of a nickel alloy known as nichrome. These heaters didn’t even need a switch to operate. As a result, it is inexpensive. It was unsafe to use, so a new design was created to avoid contact with the hot heated wire, which suggested a wire guard, which was adequate.
A thin metal reflector becomes too warm, and therefore, it needs to be pretty thick to insulate it from getting too warm. The affordable radiators in the old days consisted of thin reflectors, which wasn’t entirely safe, and it was separated away from the metal housing.
To cool it, a relatively small-sized fan was able to blow the air in its components, and the main exit to the room was not the conventionally heated air but rather the radiant heater’s heat. Stretching the heater wires on a larger surface required less (costly) ceramic insulation, and a small ventilator was less expensive than a larger one.
Working Of Quartz Heaters
They are similar to radiant heaters that are more efficient in the quantity and direction of heat, with the heating wire wound inside the quartz tubes that are unsealed. The cables can be operated at higher temperatures and are thinner than those ceramic-supported wires. Moreover, the heating compartment is more elevated and thus far more efficient as more energy is radiated than open-wire warmers.
Furthermore, The temperature of quartz heaters is not too high, as we find in incandescent bulbs. Still, they will work at a hotter temperature than those so-called nichrome-wire heaters, radiating mainly into the infrared from the electromagnetic spectrum. Moreover, more than 86 percent of the input power is converted into energy for radiation, losing the rest to conducting and convectional heat. To increase the filament life, the halogen cycle helps by reducing the dimming of the quartz envelope.
Even though space heaters can be handy in heating small spaces, they can sometimes be quite dangerous. Those risks can include fires and burns.
However, you don’t need to be worried about these. We have gathered all of the things you need to look at to avoid these risks and protect yourself from the hazards. The first thing you should probably do is obey the instructions written in the guide. They might seem entirely theoretical, but they are pretty essential. Use only the fuels which are specific for it and do not try any alternatives. Do not use gasoline in any circumstance. Moreover, refilling a heater when it is already hot can be dangerous so stay away from that. Furthermore, to avoid igniting a fire, the fuel should be stored outside.
In addition, to reduce the risk of carbon monoxide, a hazardous gas, the space heater’s vent must be monitored carefully to make sure it is working fine. It would be best to put the cable directly into the wall to avoid any risk, and when you are using it, a compact, heavy-duty cable is mandatory.
Heating appliances should not be placed somewhere where an individual could knock their leg into and unintentionally burn himself; also, such devices should be kept away from the reach of kids to avoid the consequences. Also, it should not be covered with fabrics because it can easily catch fire.
In conclusion, every heater has its benefits and a few downsides. And for one to decide which is best, you should consider their requirements to get the best of all. In convective heaters, the heating element is encircled by oil or water. Moreover, some convective heaters use the fan to circulate heated air. Same as radiant and quartz works on different principles and gives different outcomes.
Frequently Asked Questions
What is the major use of space heaters?
Space heaters are ideal for tiny places since they use a fan to evacuate and spin hot air throughout the room.
Is it safe to breathe near space heaters?
If space heaters are not installed properly, carbon monoxide might be released, which is toxic to inhale. Keeping an eye on the working of space heaters should avoid such issues.
Is it true that regular maintenance might aid in the proper operation of space heaters?
Cleaning, oiling, correct storage, regular inspection, and filter replacement help space heaters work correctly for an extended period.
