What are Infrared Heaters?

Infrared heaters provide heat just like the sun. They emit rays, invisible to the naked eye, which you and the items in the room absorb and get warmth. The heater uses a set of coils and a reflector to focus the light outward for infrared illumination. The light’s absorption warms the body.

Electric heaters and patio counter cold scares and their performance depend on a variety of variables. Using (in the form of heaters) comes after purchasing something; hence, using the most suitable heater is the answer. There are various forms of heaters available based on their function and characteristics. To choose the best infrared heater, you must research well; this is why we have prepared this guide for you. Below are a few important types of infrared heaters mentioned.

Types of Infrared Heaters

Infrared heaters come in various shapes and sizes, which might be appropriate to your room size and requirements. Here are some of the types so that you can choose the best infrared heater for you.

High-Intensity Infrared Luminous Heaters

Jet-fired, high-intensity heaters are direct-fired, flowing through a combination of air and jet into a brittle, refractory layer that ignites uniformly around the earth.

This surface is heated to or above 1350 ° F and emits a wide concentration of infrared energy that can focus anywhere you need electricity. High-intensity infrared heaters usually run unvented, and your room may require sufficient ventilation to dissipate the release of combustion gases.


These heaters are ideally designed for buildings with high ceilings and places where there is a strong need for heat loads, such as docks or bays.


The patio heaters are used to offer indoor and outdoor heating to the patios, decks, and hallways of the restaurant.


Portable heaters are mostly installed on a 20 lb., 10-inch LP base tank. They are built for outdoor or indoor areas under development. They are the perfect remedy for temporary weather.


Electric infrared heaters generate heat by running electricity through a high-resistance device. They are widely found in places where gas is not possible or inaccessible.

Low-Intensity Infrared Radiant-Tube Heaters

Gas-fired infrared heaters are indirectly ignited and have a reflective surface between ignition and the expected load.

Low infrared power, the flame is sparked inside the heat exchanger, it is heated to temperatures of up to 1350 ° F and emits infrared radiation. This energy is guided by reflectors to the floor level and absorbed by people and objects along its route. The burner/combustion end generates more heat than the exhaust end, but our well-designed systems mitigate this disparity in temperature.


The forced-drawing mechanism works under positive pressure, moving the products of combustion across the duration of the exchanger tubing. This form of an infrared heater is simple to run and build as all components are housed in one compartment. Push-tube heaters deliver a range of output, deployment, and operational advantages relative to other forms of tube heaters.

A draft-induced tube heater works under negative friction, dragging the combustion products across the duration of the exchanger pipe. This sort of infrared heater provides good output in high-wind applications and also enables increased ventilation.


Multi-burner vacuum systems run under negative conditions. An efficient vacuum exhaust pump pulls combustion products into a range of radiant exchanger tubing. This form of the heater is used when limited building penetration is needed or where enhanced ventilation is necessary.

What is an infrared heater, and how does it work?

An infrared heater or heat lamp is a higher-temperature body that passes energy to a lower-temperature body by electromagnetic radiation. Depending on the temperature of the emitted object, the wavelength of the peak infrared radiation varies from 780 nm to 1 mm.

Infrared heaters operate by transforming energy into radiant heat. Infrared is part of the electromagnetic spectrum. The wind is the same sense of comfort as the winter sun on your skin and the flame of the coal burner. It is the same type of heat that your own body emits. This is the most fundamental method of heating known to man.

Infrared is a simple flow of heat from the radiator to the target (you and the space surrounding you) without the air being heated in between. It is the same heat that we experience from an atmosphere warmed by the light, and the wavelength most easily consumed by the body. This is 100% healthy and normal (the sun’s Ultraviolet is dangerous, not infrared).

Nowadays, modern technology, in the form of our 100% energy-efficient Herschel Infrared heating device, helps us to utilize infrared radiant heating in a sleek, convenient, and fully controllable manner.

Working of infrared heaters

The functioning of the infrared is supported by infrared light that is outside our spectrum; thus, it is not apparent to our naked eyes. This operates on the concept of heating an item in a specified room, where our skin and clothes absorb this infrared light that induces a heat transfer. A typical example of how heaters operate is heated while seated in direct sunshine where we sense the heat but cannot see it.

There are two ways in which infrared function

  • Commonly direct their light into a space to heat the target it is touching.
  • Deviations involve a mixture of an ultraviolet light bulb, a heat exchanger (with strong metal), and a fan. The fan is used to push air to the heat exchanger and uses propane gas, natural gas, and energy for their service. The most popular heater is power-based stand-alone heaters. Based on the capacity of such heaters, an area of 300 square feet can heat to a height of 1000 square feet.


Advantages with stand-alone heaters

  • Cost-effective for installation and maintenance compared to propane or infrared-assisted natural gas.
  • It just takes a few minutes to warm up the room.
  • Stand-alone infrared has outstanding portability, and you can only push it anywhere you pass in your home.
  • They are easy to maintain and repair if needed.
  • Most consumers agree that these forms of heaters are so cost-efficient that the consumer can regain the expense within a few months.

Infrared heaters come in varying types, forms, and designs. It is also advised that the best infrared heater for you is according to specific specifications and budget.

The energy that we were made for

Humans are artifacts of radiance. More than 60 percent of our sense of ease or pain is decided by our radiant heat benefit or loss. Just 15% of our sense of comfort is controlled by air temperature and movement.

It means that we generally feel hot as we receive heat from our surroundings and sometimes feel cold as we radiate our own body heat to the outside world.

To certain humans, whether the temperature surrounding us is greater than 78 ° F or less than 50 ° F, we experience pain as we either acquire or lose too much body heat.

Therefore, if we heat up the walls, ceiling and floor of the space we are in (not the air) to at least 54 ° F and preferably to about 68 ° F, our bodies will avoid knowing that we are losing heat and that we are feeling the heat and relaxed. That is the aim of infrared heating: to build up the “thermal layer” in the atmosphere and to hold you dry.

Make a 360 ° radiator in your house.

Herschel infrared heats the walls, floor, and ceiling of the building directly (the ‘thermal mass’). When the thermal mass is dry, the house itself holds the heat in place for a period of time, and the radiator just has to be on top.

The other types of heaters are convection heaters, which primarily heat quantities of air, and then have to pass the heat to the building in order to heat the thermal mass. The concern is that hot air falls to the roof (where you do not like it) and escapes quickly through draughts and open doors. The direct flow of power to the house is why Herschel is more effective and saves electricity relative to convection heat. It is more convenient, too, since you do not have cold floors and stuffy weather.

Is infrared heating efficient?

Since convection heaters heat air, also the strongest competition leading to “small usage” digital electronic convection radiators, require about 40 watts per m3 in order to help ineffective absorption of heat by air and the weak flow of energy back out again.

Herschel infrared panels do not heat the room, but they typically only require 25 watts per m3.

It’s alright if you were assuming that a kilowatt of energy will have the same properties of heat transmission, whether produced by convection or a radiant heater, but this is not true. Radiant power has a higher rate of heat transmission per kilowatt than convection, and you need fewer.

All Herschel and electrical connectors operate for around 40 percent of the necessary heating time (often referred to as “efficient power”), although the fundamental disparity in heat transmission implies that Herschel might save up to 37 percent of the cost of energy relative to convection and night storage heaters.

Can infrared heaters heat my house?

Infrared panels will heat the whole room. They will not have to be solely to make up for insufficient central heating or extensions. In reality, most of the people who buy infrared heaters use them to upgrade the currently installed device – be it storage heaters or wet/dry central heating. They are especially valuable for homes that are “off-board” (i.e., not on gas lines). The low-watt specifications of infrared heaters relative to convection heaters render it an appealing energy-saving heating option.

Convection is when the atmosphere heats up due to the passage of hot air. Such as by storage heaters and gas central heating systems. Convection is a weak transmission of heat to the structure of the building or items in the house. And when the radiator is turned off, the air cools off easily. Infrared panels operate by heating materials, creating the thermal mass of the space by heating walls, floors, and other items. These surfaces then build up energy and radiate back into the house, even when the heater is turned off. It is this concept that allows Infrared devices to have an initial wattage smaller than convectors and to operate for less time as well.

Will infrared need the same amount of watt as convection?

If we take a living room of 4 m x 4 m, you will just require an infrared panel of around 1kW (depending on the building design, etc.). Yet to heat the space using convection, you will need a spectacular 2.4kW – so you might not even feel warm as easily!

How are you supposed to figure out how much heaters pay to run?

You need the watt of the boiler, the number of hours it is on, and the price in p / kWh to decide how high the heating costs are. But lets split it down into prices, considering 1kWh as 11p.

The 5-hour infrared heater will cost 55p (1kW x 5h x 11p / kWh)

Convection heater costing $1.32 (2.4kW x 5h x 11p / kWh)

55p compared to $1.32 to heat the same room!

Could you monitor room temperature with infrared heater panels?

Infrared heating is not only a perfect primary source of heating. Mainly ecause of the strength and intensity at which the air is heated. But also because of the time and temperature regulation it offers you. You can connect your panels to any number of thermostats to offer you the absolute room-by-room control of your house. We suggest one control per room, and you may want two in wide rooms (because you may want to heat various areas differently).

Can infrared heaters heat a room? Not only will infrared be the main means of heating in a home, because it can do this by utilizing a fraction of the energy, so it has to in the correct deifinition. When it is, it provides the ideal option for heating the entire building.

Do Infrared Heaters Work Well?

Pros in the usage of an infrared heater

  •         Instant Heat: Infrared heaters are beginning to release infrared light as soon as they are switched on because they are burning bodies because objects and not the environment they need absolutely no time to warm you up.
  •         Quiet: Because these heaters use light to warm you, they do not have to have a fan and are thus much quieter than the engine heaters.
  •         Efficient: for such heaters, there is absolutely no waste because it heats just the items and the people led to them, and not the whole rooms or locations.
  •         Environmentally friendly: Infrared heaters are a safe source of heat. They will not introduce any chemicals into the atmosphere. They do not use any fossil fuels or burn any wood to generate their electricity.

Cons in the usage of an infrared heater

  • Light-Emitting: Firstly, the infrared heater produces an orange light. While this does not concern certain people. Because the lighting may differ between versions. This sort of portable heater may not be suitable for your bedroom at night if you are prone to light while sleeping.
  • Restricted Temperature Delivery: Secondly, infrared heaters just heat objects in their direct line of heat distribution. Such that they are not suitable for heating broad spaces or spaces where people walk about constantly.
  • No heat When switched off: Lastly, since the infrared heaters will not heat the environment. It would rather heat the structures that the infrared light touches until the heater is shut off the heat. This means the heat instantly dissipates when you turn off the heater
