Hello everyone,
My husband and I attended a home exhibition today featuring a local timber house builder (Schleswig-Holstein) and there we learned about the Vestaxx window heating system.
Is there anyone here who has experience with the Vestaxx window heating?
At first, it sounds unusual to have the heating integrated into the windows. For the triple-glazed windows, a nanotechnology-based, invisible layer is applied to the inner surface of the innermost pane, which warms the glass up to 40 degrees Celsius (104°F) via infrared and heats the room. The warmth actually felt very comfortable, and the windows were completely cold on the outside (today’s temperature was below 10 degrees Celsius (50°F)). Allegedly, the Vestaxx window heating transfers 92% of its heat to the room, and the Technical University of Berlin has tested this Vestaxx window heating system and rated it positively. It appears to have been on the market only recently.
Overall, I find this quite interesting. It is significantly cheaper than other heating systems, allows individual control of each room, and unlike underfloor heating, it is very responsive.
Of course, this only makes sense in a low-energy house (the timber builder mainly constructs 40+ standard homes), as the system runs on electricity. In that case, the Vestaxx window heating is said to consume very little power.
This is my impression from the expo; of course, they want to sell the system.
What are your experiences with Vestaxx? Have you heard of this system before? Could it be an alternative to conventional heating? Does it have a future?

I have reconsidered and think Vestaxx needs to approach its selling points differently.
The target group could be, for example, genuine Bauhaus architecture under historic preservation. Exterior insulation is not possible, so interior insulation is used: many walls need to remain free, large window areas, and the facade must not be spoiled by external heat pump units.
Older residents of old existing buildings who will soon need to upgrade their roofs, windows, and facades for energy efficiency but realistically will have no money left or incoming funds because they are already too old. They could initially use the heating system with window heating since they might not mind that a heat pump will perform better after 10–15 years. However, they probably won’t invest the savings in anything else, as they expect not to live much longer.
Then moving away from windows entirely, because as I understand it, the product is not primarily the sophisticated window heating, but the special process of applying heating elements onto glass.
This means the process itself should be the main selling point and extended to other product groups: for example, glass shower partitions. Bathrooms always have low heating demand, and not everyone wants or can fit an additional radiator. Wall heating is inconvenient, and not every plumber installs underfloor heating in showers.
Car windows should not fog up, heating wires are problematic, and fans are not fast enough.
Animal enclosures, aquariums, terrariums, herbaria for tropical animals. My wife currently uses heating mats placed under the herbaria, but that is less efficient and not as sleek.
In miniature, eyeglass lenses against fogging.
Rapid drying and pressing of plant materials.
Just some ideas.

... or monitors that also function as facial tanning devices so you can always look like you’re on holiday (at least visually) 😉 Although… that’s a film inside the monitor, not glass.
No, just kidding. Your @Tolentino ideas are great, and I think with a different argumentation and a more appropriate target audience, Vestaxx wouldn’t have faced as much resistance here.
I would get it protected > all-glass heated shower walls, and if the additional cost is reasonable, I would have them installed in my next house directly.

I had the bathroom in mind as well. I also considered a window there, but the glass shower wall actually sounds even better 😳 Without going through the entire thread: Would this system be suitable for heating individual windows, or do people usually go with an "all or nothing" approach (because there are dependencies that I’m not aware of)?
I thought this was about experiences? With the heating windows, we saved ourselves the entire installation of any other heating system, as well as all maintenance and upkeep costs. We don’t need a tank or pipeline for gas or oil. We don’t need a chimney sweep. The windows do what they’re supposed to, and with photovoltaic panels on the roof and a battery in the house, the costs are low throughout the year.

I'm not really one to pinch pennies... I simply compared the costs of a conventional heating system—about 35,000 to 45,000 €—to the additional costs of the heated windows. This results in savings of roughly 27,000 to 37,000 €. Solar panels on the roof are basically standard for new builds these days. So I thought, with the money saved, you can heat for a long time...! Plus, the chimney sweep doesn’t make a mess anymore! In rooms with small windows (for example, the guest toilet), I also installed a heated mirror.
It takes about 1 to 2 hours for a cold room to reach around 20°C (68°F), but if you stand in front of the patio door that long, you really feel like the sun is shining!
