Advice on heaters

cameramonkey

Hi,
I am thinking of getting these heaters for a room that is getting built. Does anyone have experience of these?

Hi,

Those heaters are cheap and cheerful. They are much the same as a small fan heater stuck to the wall.
If you are getting a new room built and dont want to extend your CH system, electric radiators would be a better option.
They would be cheaper to run than what you are proposing and would give a more comfortable level of heat.
I dont know how expensive they are as it depends on the size.
There are various companies doing them but I have seen these ones in a friends house in the garage and sunroom extension. They were in the house when they bought it so dont know how much they cost. Have seen them in action a few times in their house and they warm in up the room fast. Seem to come with the usual control gizmos.
I would be interested to know the price of one of these if you get a quote

Thanks for that. will check them out and get back to you.

I have one of these in my office, its great.
Infrared, rather than convection, with a thermostat, and timer keeps me snug all year round.

They look good and modern. I was trying to figure the input and output efficiencies of these systems when I found this gem of sales bull.
Although it is many years since I last studied thermodynamics and it was in Germany, I find this very amusing.
You should be careful, cameramonkey, as these heaters need to be used in a vacuum!

Radiant v Convection

Far Infrared panel heaters radiate heat.

Radiant heat relates to heat transferring directly from the heat source to the object being heated, without interference from the air in between.

Convection on the other hand relates to the heat source heating the air around it and as hot air is lighter than cold air, hot air rises and within the confines of a closed space the air circulates, delivering heat as it does.

Contrary to popular belief, heat does not rise, “heat transfers”, “hot air rises”

As radiant heat is not concerned with the air, the issue of hot air rising does not enter the equation

While not wishing to question your understanding of the law of Thermodynamics, I have tho 60 X 120cm mirrored glass model in my office 20SqM.

With a slightly complicated Thermostat, this past winter my office was at a constant 20deg when I arrived each morning, and remained so throughout the day.

So while I do not know how it works, ''It Works''

How do you find the running costs?

@previous poster: infrared radiation will happily propagate through air, no vacuum required

Electrical bills down, by about 10%, last winter compared to previous.
Hard to say that's from the heater, alone, as I have computer, printer, and other electrical equipment, but that's the only variable, over the two years, other than the harshness of the weather.

What heating did you use previously?

One of those Oil Filled, free standing radiators, two settings 750W + 1250W, took an age to heat the office on a cold morning.

Does the heater have to face you directly without obstructions? What if there is something in the way or the heater is in a corner?

Mine is wall mounted, close to the corner, suppose if there are obstructions, they will get heated, you can also mount on ceiling, the idea is that the heat radiates heating the walls, ceiling, and yourself, not just the air-mass.
