"High-E" glass. What a novel idea.

It is, in my opinion, impossible that this device would actually save heating energy - just the opposite. And as far as I know, in most EU countries and most developed countries, this company stating that this device does just that constitutes a crime - with legal punitive consequences. Seems this company has a lot of PR people on the payroll and an absence of lawyers.

First off, it is the perimeter of a window that would allow for drafts, not the surface area of it. Heating up the area around a draft will not get rid of it, stopping the air movement will.
Second, turning a window into a radiator will not provide warmth to your home. By heating your window, you will have a much greater delta T from window to outside than window to room, and so the heat will travel out.
The only comfort I can see this thing providing, is that if you were to sit right next to a window, your body will not radiate as much energy too it. A much more eco friendly solution to this would be moving your chair.

This is definitely up there with running hot water pipes under your driveway and walks in order to melt snow.

There's rationale to putting a heat source by windows, after all that's where radiators generally went. This was in order to prevent cold spots at the building perimeter.

At least it keeps your windows from frosting up!

But I'd rather put my money in a little pile and have the satisfaction of watching it burn up prettily, than by buying any of these windows.

throw a rock at it. it'll save energy.

What ever happened to double or triple paned insulating windows?

The only thing this would be good for is preventing someone from spying on you with an IR camera.

... what temperature can it get depending the environment?

It's simple physics.
Heat transfer always occurs from a hot body to a cold one, a result of the second law of thermodynamics. - so most of this will simply go straight out through the window. What a dumb idea!

And as the warm transfers out the window, the now chilled air on the inside falls to floor like a slow motion water fall creating the draft you feel at the floor as it spreads. You don't need air leak to feel draft.

You can track the cold layer in it's flow and mix with incense sticks.

By all rights, the floor should have full width vent to receive the cold air falling off the glass to the floor. To be recycled later to the heat source.
Gravity cold air returns are very efficient. It's worked perfect for a thousand years. Leave your basement door open so cold air freely flows to lower area. If that area is not used.

Split level homes are the worst if lower area is used for theater center. The entire airspace of the upper levels of cold air will freefall there.
The best then is a heated floor for that area.

The use of ceiling vents for heated forced air in the lowest level is totally wrong. You can not force heated air to the floor by the furnace alone. Cold air is too heavy to move out of the way. And is why you suffer chill drafts there.
The heating industry has no clue as to how to make the lowest level politically correct for heating.

The upper most level of split level should have hot air vent tube at ceiling to recycle back to the lowest level at floor.
It also keeps the lower area dryer and bug free.

You can also just open the furnace panel at floor level to draw the coldest air to enter to even out the heat at the lowest level.

In all my tours to Europe, I have never seen forced air heating. It's 100% steam boilers, or like Sweden, central steam from the street to your home.

This is hardly a new invention.
First time I saw radiating windows and mirrors was nearly 10 years ago.

At that time the concept worked similarly to the same effect you have when you're sunbathing in the snow.

The air temperature is low, but the "warmth" from the sun keeps you comfortable. That's how you save energy: you can have your indoor temperature well below traditional "comfort" levels, but as long as you're receiving the radiating heat from a window, you feel warm just the same.

At the time I tought it would be most useful in bathroom mirrors, as you could use it just when you shower and turn it off as you leave.

I am an architect, and I looked into this on the request of a client. My impression was that the manufacturer was fishing for applications for this- the original idea was to use it for windshields for aircraft to prevent fogging and icing, which is a great idea- using the heat transfer through the glass as an advantage. The manufacturer came up with the fogless mirror idea, a towel warmer, and this application for 'warm glass', all of which are obviously pretty silly.

It does have to be said that the intention of the manufacturer is to install this in an insulating glazing unit assembly (IGU), so as a double or triple pane config, but it is still grotesque. And their claim to be eliminating draft is technically correct, as draft is the cold air falling from the glass as it is chilled at its surface, leaks are the passage of air inside or out at the window's perimeter, and with good window manufacture and proper installation can be nearly eliminated. Don't buy Thermique, do buy the best windows you can afford and install them carefully.

The manufacturer's claim of being green is totally 'greenwash', thanks for publicizing it. By the way, I lost the client, and I sleep better at night!

ignoring the whole factor of throwing energy out of the window. (lets say i have thought of a usefull way of using this with out waist ing heat)
does any one know how well one could recycle these windows?
