whilst we were away last week, the site we were on had a ban on fires. BBQ`s were ok, but no fires.
now i normally enjoy a nice fire, but only burn them logs from B&M that dont smoke, just in case i meet mike on site. we have a folding bbq that doubles as a pit.
anyway, we toddled up to shrewsbury and happened on a store selling off all their garden stuff cheap. so, i became the happy owner of a new quartz patio heater.
a quick rummage in the bin area on site and i happened on some of them led lights on stakes so i made myself a low level quartz heater.
like so
like bob, i wasnt sure how much it would work. the closer you sat, the warmer, obviously, but it did warm quite an area. if you were in the awning and you turned to face it, you could feel the warmth on your face.
the red glow wasnt noticable and when walking back from the toilet, you could only see the glow on our legs,
however, i took a pic and after messing with my cameras settings, managed to capture the infared glow, and its a good illustration of how far it reaches.
like this
the heater is in the floor, six foot in front of our porch awning, with three chairs lined up and the missis in the middle one (its hard to make out)Post last edited on 10/08/2018 11:20:55

Imagine space is full of air and the sun is blowing out hot air. Do you think you would feel that hot air 93,000,000 miles away. I doubt it.
A fan heater in your tent will heat the air but most of that hot air will be lost in draughts. A lot of energy is needed to heat that air. Radiant heat will heat you not the air so you get the benefit not the field outside.
Radiant heat travels in the same way as light but at a slightly different frequency on the electromagnetic spectrum.
Yes but the sun doesn't just heat your body it heats the entire atmosphere as well, so everywhere feels warm. If the sun goes behind a cloud there is still warmth in the air but you feel cold because the heat stops.
A fan heater is heating the entire atmosphere continually whether you stand in front of it or not.
I didn't read it as the colour being enhanced, Jedsjeep, just that the camera had been set to show the glow in the dark. Not being an expert on heat I believe a quartz heater gives out heat and light so half the energy is wasted in light.
Taken from this website
Do Quartz Halogen heaters give off light?
Yes. This is inevitable because shortwave infrared is right on the edge of the light spectrum visible to humans. In older types of elements, the light output is a deep and unpleasant ruby red. All SunSwitch heaters have elements with a gold coating that increases energy-efficiency and produces a more neutral, pleasing light. When correctly positioned above normal sight lines, the light is not intrusive. Any colour is easily washed out with normal lighting.
