Infrared radiators

Anyone have any experience with these? We are looking at some for our place to replace existing electric radiators.

Re: Infrared radiators

I am not sure that is legal in CH anymore to re-install Electric heating when it's primary source of heating while when it be secondary source likley that is not an issue.

They work but it is more "target"heating via radiation rather than typical air heating you have from standard radiators

Re: Infrared radiators

I use some for an outdoor patio - a good replacement for a campfire. It is very good for spot heating, but not for the air heating .

But wouldn't consider them for the inside of the house, unless we are talking sauna, workshop or a döner stand:

  • Exposed IR heaters are too harsh for conventional use at a high power. Really hot, sitting in its direct rays breaks sweat almost immediately.
  • They are quite useless at a low power settings, since they can't heat the space without some extra forced convection or some huge passive radiator.
  • They can't store the heat and slowly keep the room warm, like the water heating does, since IR radiators have no substantial mass in the first place.
On the other hand, one can point such radiator at his castle's stone wall to heat it up - then it may be an efficient solution.


Also, there may be some product, which has no of the above mentioned flaws. I just had never came across one.

Re: Infrared radiators

I use one in my office downstairs which is very cold. I like it very much, it heats - me, LOL, as someone wrote, it heats things not air, although once I left it on over night and wondered why the office was such a pleasant place all of a sudden - when I need it. For me there is no point in heating that room permanently in winter.

NOTE: It is not recommendable to leave it on in your absence. I felt rather lucky the next day and have not forgotten to turn it off since.

Then there are those - they can be left on in absence, no problem. They heat only to the front, not in the back where they hang on the wall. They sound groovy and I researched for a while but came to the conclusion if I wanted to heat my 21m2 room downstairs with them, I'd need a huge one. And again, the electricity it would eat up would not be worth the money in my case. I also stayed in a room with one of those at a friend's place once and was not very impressed with the effect.
