History of Room Heaters:

Since ancient time, humans are more keen to keep themselves warm during cold weather. Adding fireplace near the opening of caves (where human used to live in ancient time) was the first attempt to keep the environment warm. Over the years, this technique evolved as human found various other ways and explored the science behind the temperature.

After the fireplace, they used furnaces to generate the heat. They even used the central heating system to channel the heat across the house. Rome was considered the founder of the central heating system for the home. They used pipes to channel the heat from the furnace to the rest of the house and kept these pipes behind the wall so that the house should remain warm.

Nowadays, keeping the room warm is an easy task. You just need to buy a well-designed heater which does the trick. Dave Lennox is the first person to manufacture the steel coal furnace in 1895, but it was not efficient as it should be because the heat was transported via natural convection instead of fans.

After few years, Albert Marsh came up with an alloy made from the one part of Chromium and four-part of Nickel which was 300 times stronger to transport the heat as compared to the similar material available at that time. Albert Marsh is considered as the ‘Father of Electrical Heating Industry.’

Soon after Albert Marsh’s discovery of new alloy, room heater becomes more efficient and popular. Today we have portable room heaters that can be carried anywhere as well as they are more efficient to keep the room warm. Also, they are constructed with durable, light advanced metals as well as ceramics material.

How do Heaters Work?

With so many options to choose from, users get confused about which heater to choose and how it will work? Though there are several types of heaters available in the market, every heater has three basic components that play an important role to generate heat.

The three primary things that every heater includes are:

  1. Heat source
  2. Heat Distribution System
  3. Control System

How does room heaters works

Image Via: Energy.Gov

Heat Source

The main function of heat source is to generate the heat, which is then distributed further to keep the house warm via specially designed distribution channel.  It can be a heat pump, furnace, boiler, or heating coils.  Out of these sources, coils are most popular as it allows to convert the electric power into heat.

When you switch on an electric room heater, electric energy runs through the heating coil and due to the resistor it is turned in to the heat. While in other heat sources like furnace heat from the fire is used.

Heat Distribution System

Once the heat source starts generating the heat, the heat distribution system comes into play and starts picking up the heat. It does so via transforming cold air over the heat source. As air flows over the heat source, it picks up the heat from the heat source and become warm, which is then blown out of room heater using the fan.

Control System

The heat control system is also known as a thermostat, and it helps to control the amount of heat distributed via room heater.

Advantages of Using Portable Room Heaters

Portable room heaters are versatile and have numerous advantage over the centralized room heating system. Let’s see how it will benefit us.

Affordable

Portable room heaters are a cost-effective solution to keep the room or office warm. They cost less than the centralized room heating system and help us save money. Also, they will consume much less energy to operate than the central heaters.

They do not require any installation except few portable room heater comes with wall mount where you will need to mount them on the wall, but as compared to central room heaters you will save lots of money on the installation process. Not only that, but it takes less for portable room heaters to maintain them.

Versatile Heaters

As discussed earlier, portable room heaters are versatile. They can be used where central heating can’t be a viable option. You can use them in the bedroom, garage, office, or a shed. They can also be useful where home renovation is going on.

Energy & Fuel Savers

These heaters are energy and fuel savers. As you will use it to heat the small area, it will not require more energy or fuel to run. Also, all room heaters are energy efficient, they convert almost all the energy or fuel into the heat leaving no room for energy or fuel loss in the process, so you pay for what you get.

Types of Room Heaters

The Indian market has several types of room heater to offer. But the most popular and efficient types of room heaters are as follows:

  1. Fan heaters
  2. Oil Filled Heaters
  3. Infrared Heater

Fan Heaters:

As the name suggests, these heaters use the fan to blow the air out from a heater. These heaters include the heating elements which usually connected to the electricity; this heating element heats up the air, which then blown out by the fan and helps to warm the surrounding room. They are also known as the blow heaters.

Fan heaters are more efficient in the closed room. They are less expensive to buy, but they require more power to run, so if you want a room heater for daily use, then fan heaters can’t be a good fit for you. Also, they are noisy as they use the fan to blow the air.

Oil Filled Heaters:

Though these heaters are named as ‘Oil-filled heaters’ they do not run by burning oil; instead, they use the oil as a heat reservoir. These heaters are also known as column heater as they consist of the few metal column and cavities. These cavities are filled with oil which passes over the heating element then flow freely across the heater, releasing heat to the surroundings and keeping the room warm.

Once the oil releases the heat, it becomes cold and flows down toward the heating element due to the gravity. This process of heating the oil is known as convection, so the heater is also called as convection heaters.

Often, oil heaters are cheaper and efficient to run and typically uses 300 to 2400 watt power so they can be termed as the low power consumption room heater. The only concern that these heaters bring is that they are prone to fire and burns.

They may fail down when kept on an uneven surface or can easily be knocked over. So it is advisable not to keep anything within the three feet area of oil room heaters.

Infrared Heaters:

Infrared heaters are also known as the heat lamp. It uses electromagnetic radiation to transfer the heat from the element with high temperature to the element with low temperature. The best thing about these heaters is they do not require the medium or contact to transfer the heat so that they can be used in vacuum or atmosphere. They work by emitting infrared waves with the wavelength ranging between the 1nm up to the 780nm.

As per the wavelength bands they emit, infrared heaters are divided into the short, medium or far wave infrared heaters. Also, as per the type of material used in the heater, they can be divided into the heat lamp, ceramics infrared heat system, metal wire element heater, carbon heaters or gas-fired heaters, etc.

Features of Room Heaters You Should Look (Buying Guide)

Whether you are in the office or home, a room heater can give an extra boost to the room temperature and will keep the temperature optimum so that you can relax. While buying the best low power consumption room heater, you need to consider few things so that you will not end up buying the heater you don’t want.

For the same purpose, we have done the heavy lifting for you and jolted down the several features of the room heater as well as various tips that you can read before buying the room heater.

Automatic On-Off Switch (Safety Settings)

Heaters can lead to fire or burn the skin if you accidentally touch the hot area. To prevent further damage every other heater in the market has touch sensors that switch off the heater if someone touches the protective grill or accidentally knock down the heater.

Wattage

Usually, the heat output of the heater is directly proportional to the wattage of power it consumes. The more wattage it uses, the more heat it will generate. So, you need to decide how spacious room you need to warm using it so that you can decide on the wattage.

Most homes in India has 5 Amps socket to you might need to go for a heater that uses less than 1000 Amps, or you might need to install a socket with higher Amps.

Handle of Heater

The handle of the heater is the most ignored but useful feature. Design and placement of handle of heater matter a lot as it allows users to move room heater from one place to another with any problem.

Length of Power Cord

You don’t need a heater that confines near the socket just because it has a short power cord. Buy long power cord so that you can save the money buying an extension board.

Heat settings

You may need to change the heat settings as per the environmental temperature, so it is important to have the ability to change the heat settings. Apart from the heat settings, humidification is one more important aspect that you should pay attention to.

Heating Capacity

It is a self-explanatory term which helps you identify the maximum amount of heat a room heater can generate. The more the heat capacity, the more heat will be generated. But keep in mind that the room heater with more heat capacity will consume more wattage leading to more energy bill.

Noise Level

Often, the room heater uses the fans to blow warm air in the room. The fan may cause noise. You certainly don’t want a room heater which creates constant noise. Also, electronic devices tend to create some noise, so you need to choose the room heater, which creates less noise or doesn’t make any noise at all.

Level of light emission 

Heaters often tend to emit the light.  Bright light may cause trouble during the night hours, so you must pay attention to the level of light it may emit to avoid the troubles during its use.

Type of plug 

The heater comes with either standard or power plug. For the safe operation of the heater, having a safe plug is an important feature to have.

Energy Efficiency

Every room heater demands some energy to operate. If we can focus on getting energy efficient room heater, you can able to save some energy in the long term. While buying a room heater, look for its energy ratings, it will give the basic idea of how much energy efficient that heater is.

Usually, room heaters do not follow the best practices of energy savings, at least look for the room heater which incorporated some basic energy efficiency standards. Buying energy-efficient heater will save the energy in long term usage and will allow you to be a part of the global energy conservation movement. Apart from that, it will save some money on the electricity bill.
