How do quartz infrared heaters work? How efficient are they?

Question

I'm wondering about the advisability of buying one of these heaters.

Answer 1

they are not advisable for ordinary home heating purposes. because they must radiate to function, they have a much higher fire potential than resistance type electric heaters.

IR heaters are good for drafty barns, garages and workshops. the radiation will warm the skin and clothing without having to provide the heat to warm the air. the effect is much like standing near a bonfire.

they need to be strategically placed because if your position is shadowed, you will cool quickly. Normally they are placed high, much like a lighting fixture, which is the opposite of normal heaters. Because they have no "thermostat" function, they should never be left unattended even in industrial settings. And they provide no benefit when no one is around to absorb the radiation.

Quartz Heater

Answer 3

All the electricity used by the heater will eventually end up as heat, so in that regard all electric fires are 100% efficient at heating.

A quartz heating element, works much like a light bulb, only in there case, they are optimised to produce as much infra-red as possible, and less light.

As to the advisability of purchase it really depends on what you're wanting the heater for.

As the heat is infra-red it is projected through the room where it continues until it hit a solid surfaces which it then warms (direct heating of the air is negligible, some air is heated near warmed surfaces). Having warm surfaces is often all that's needed to make a room feel warm, and it provides considerable saving in energy.
Just be careful about having objects too close in front a radiant fire as they would get very hot/might ignite.

If you're wanting to heat the air, (called space-heating), a portable gas fire usually ends up being the cheapest in the long run. (just need to be a little aware of a small potential risk for carbon monoxide, which isn't that large so long as gas fire is probably serviced, and room has adequate ventilation) some water vapour would be produce by the gas burning, so you might get some condensation on cold surfaces/windows etc.

Answer 4

All electric heaters are 100% efficient. Not all are safe to leave running unattended, they can start fires. If you run your thermostat cooler and heat just the area where you are (with a space heater or electric blanket, etc..) you will save money. If you expect the heater to heat the entire room, you probably won't save energy.

You may have seen an infomercial about a type of heater which uses quartz elements. Do your homework before buying one.

answer # 1 is the height of BS ; i'am just one of many people here in my province that uses inferred heating AND VERY CHEAP compared to other types of heaters,,,my house is 40 years old with new doors and windows ; over the course of two winters we tested the different types and found that the quartz inferred heater aperated with approx 35 % LESS COST ; or about 90 cents a day ; right now it's +5 c outside and we have only ONE inferred heater running and it's cutting IN and OUT Nicely set at 72 ; we are hear in very light clothing ,short sleaves .

if you have that type of furnace and it was installed properly then all your heat ducts have dampers in their lines to control how much heat goes to the rooms all you have to do is find those dampers and turn the dampers, if you don't have those then all your vents diffusers should be close-able just close them a little until you get the desired temp in each room. don't close off the vents just control how much air you want in them. why waste money on other forms of heat when you have close too the most energy efficient furnace already
