- Even though infrared heating technology has been around for decades, it's still a relatively unknown concept in the HVAC industry. Infrared heating is similar to the sun in that it gently warms people, floors, and objects. As a result, these objects retain and re-radiant heat back into the space and not up to the ceiling or out the door like air heaters do. This translates into greater comfort and energy savings. Even the premier HVAC trade association, the American Society of Heating, Refrigeration, Air Conditioning Engineers (ASHRAE), recognizes these facts and has recommended reducing building heat losses by fifteen to twenty percent when using infrared equipment.
How is this accomplished? Infrared heat is part of the electromagnetic spectrum. The wavelength defined as infrared, is the portion of the spectrum, just beyond the visible red light.
Infrared heating utilizes all methods of heat transfer - radiation, convection, conduction, and absorption, most important of these is radiation. Our heaters radiate infrared radiation. This is the transfer of energy in wave form from a hot surface to relatively cooler surface without any means of heat transfer, such as air. It is a direct transfer of energy. The ability of an object to absorb infrared energy is also very important. Most materials within a building, such as concrete, metals, and water are highly absorptive. Therefore, making it ideal for heating with infrared. Conduction is the transfer of heat through a solid object. This allows the building to heat evenly by spreading the heat throughout objects and warming the air through convective energy from these warmed objects. These concepts combined cause the heating dynamics of a building to be different. The heat loss to obtain equivalent comfort is less. Therefore allowing the user of infrared heater to use less energy and install less heating capacity.
Infrared heating systems consist of a burner, heat exchanger tube, and reflector. A flame is ignited. That flame is drawn down a highly emissive tube by a fan or pump and then a geometrically designed reflector directs heat down toward the floor.
Easy to install, maintain, and operate. Infrared heating is clean, quiet and draft-free making it ideal for large spaces like warehouses, manufacturing areas, transportation facilities, airplane hangers and many more. Infrared heating is a win, win, win for building owners, occupants and installers alike. Roberts Gordon invented the first gas-fired low-intensity infrared heater and remains the leader today with the most efficient robust product offering in the industry. - วิทยาศาสตร์และเทคโนโลยี
Thanks for sharing the video
The spread of radiant energy from devices, of course, is not at all the same as in this video, but in general an interesting plot)))
is it generally more efficient to have the temp set higher or lower?
Need to increase the volume.
Can you use when you have a wood roof thats like 10ft tall
How does the heating panel connect to each thermostat? Do you have to wire it through the walls?
depends on which system you use:) wire is possible but not perfect:) its possible trough gateway (internet) or radiographic:) #verylateresponds (and im not from this company:)
SInce you seem to know your game, may I ask a question? A part of our bedroom is north oriented, making it cold and susceptible to mold. Hence, we are planning to install an infrared panel, since there are no other means of heating in the room, except airconditioning. Should the infrared panel be ON the north wall or should it be facing towards it from a different angle? Thank you in advance
I would face towards north wall so you will technically heat the area the weather is sapping heat from
depends on what you want to do with the room:) the best place to install infrared heating is always on the ceiling.
Just get a dehumidifier
Hi Robert Gordon. I became familiar with your system many years ago (1985/) when agreeing to heat a greenhouse of 3,000 sf, as cheaply as possible, since I promised to supply the heating for a friend wanting to demonstrate his seed distribution innovation. I did use infrared, but differently than you folks do.
Would you be interested in incorporating my technology with yours for the following reasons:
1) Your present limitations over large areas would be overcome, since my units can be continuous lengths of 20-+2000'.
2) Your burner exhaust losses and hot discharge pipes would be eliminated.
3) The heated pipe would have exactly the same temperature along its total length.
4) My systems installed so far, have been powered using Electricity, Steam, Hot water, heated using NG, Propane, #2OIL, Wood chip, and 4' wood logs.
5) My system heated a 10,000 sf greenhouse for several years through very cold winter snowstorms, high winds, and temperatures to -32F recorded at midnight.
6) I'm getting older.
My total heat use was 225, to 250,000 BTUs. Not once was a single tomato plant lost.
I thought I would check with you first.
Please let me know if interested in further discussion.
Igas-Energy in the UK would be interested in developing that and this technology!
They are producing oil, nat gas, hydrogen and geothermal heating.
You can find them on their website or twitter.
Hmm, no wonder my snow was melting off the roof even though it was only 12F out.
Our house is 3 bed semi detached with solid bricks (no insulation). We installed Infrared Panels 2 years back as per the guidlines given by provider. Our personal obervation these are slightly costlier especially in core winter (Nov to Feb) when on an avg outside temp is 0 to 6degree. These panels take longer time to heat the room e.g. the hallway panel takes almost 12+ hour to heat our hallway and that too only 17degree. If we want 21degree temparature in our house then we have to keep them on for many many hours. I am presuming this could be because our house is solid brick with no proper insulation. Could you please advise what can be done to improve the efficiency? As of now we are very disappointed with them.
At Roberts Gordon, we manufacture infrared tube heaters for commercial/industrial (mostly non-residential) use.
The main difference between our heaters and heaters approved for residential use is the standard to which they are approved.

Also note, infrared heaters heat objects and people, not the air. Thermostat temperature can be set lower due to perceived comfort levels. Learn more about infrared heating (www.robertsgordon.com/infrared-heating).
Thanks for your reply. Its useful!
infrared supose to heat objects not air, so i believe if you will be sitting in front of it you will be ok but actual air in the room not really heating up. we installed one in our workshop which has open big doors, so heater is placed on wall above work bench.. if I am standing in front of it I feel the heat , but its not heating air. Now one of my customer asked to install that ir heater in his bedroom, not sure about that, I am abit sceptical on ir heating in domestic house,+ heaters which looks like a picture is not cheap at all.. in my opinion you would have alot warmer room and save way more money with energy eficiant panel heater, they look good, have display, programming for all days and are cheap to run
@@spartt4360 what kind of panel heater were you referring to? I am trying to find a heating solution for a basement bathroom (which I mainly use). I am not a home owner and I don’t know much about the options (which I’m currently looking into). I’m a little confused on what’s available and what would work best. I believe based on your comment that I need to look for something that heats the air. I’ve seen heating panels that say infrared panels and radiant heating panel, I’m assuming those are different things? I’ve heard the heaters that blow air can make if drafty in a bathroom so I’m sure about that.. any tips?
@@spartt4360 actually I just went back to look at the product I referred to as a radiant panel heater and it says that in one spot but then in another spot on their site it says infrared radiant heat panel..
It's not harmful to stay in those radiations for a prolonged period of time?
no, the difference is in long wave and short wave infrared. (shortwave is a sauna or terrace heater)
Gas , clean ?
Gas fired ir technology? what
Gas fired infrared technology is an efficient way to heat your building by gently warming objects and people. Are you familiar with low intensity gas fired infrared heat? Visit our website for more information (www.robertsgordon.com) or Contact Us (www.robertsgordon.com/contact-us) with additional questions. We are happy to help you.
It relies mostly on convection heating like most home heating solutions. While it's may be (very likely) more efficient than an electric coils it's still using the same concept to heat a room. With a true radiant heat system any line of sight obstruction would eliminate the radiant heating effect entirely. We don't experience that because we are surrounded by air thus all we always experience convection heating even when completely shaded. We still experience the radiant effects the sun is the best example. If you've been lucky enough to experience a total lunar eclipse you have experience this first hand as the temp drops ambient temp drops about 11F degree during totality. It only drops 11 degree's because the bulk of heating on earth is from convection and conductive heat. In space where the other forms of heating don't work the temp drop would be several hundred decrees literally about 248F to -412F
The suggestion that the radiant effect is getting more efficiency from conductive heat is dubious at best and likely not true at all. That's not to say it's that's it's not more efficient just suggesting that it's primary form is heat transfers is radiant is not truthful at all and calling it infrared implies that.
@@GlassTopRX7 electric heat is the most expensive, gas is a whole lot cheaper bud
@@GlassTopRX7 unless you’re in bfe but even then use propane
I thought its a electric power energy and i see some gas burning😮
Not clearly explaining.
how slow are you
This is such rubbish "the sun heats people". Wtf?
go back to school dim wit
You don't think the sun heats people?
@@grizzybear9111 LOL! I see you have no time for nonsense.
No that's exactly what infrared heaters does it basically heats object says directly hits. That's why even in the winter when it's sunny out you can still feel pretty warm that is if the wind isn't being a pain in the ass. But it also means that any obstructions means that the objects behind those being hit with the light the infrared right won't get heated at all. So there are downsides too
Yet another vid with annoying incessant completely uneccessary backgound music, so another downvote.
