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?

An electric heating system that is purely electric and cheap?
How so? I wrote "NOT optimized cheap."

Unless the radiation hits solid objects that warm up and heat the air through convection. Or the radiation directly heats the person who prefers it warmer.
@EinHausfür5: How did the warmth feel — similar to an infrared panel that becomes significantly warmer as an object?

And with a southwest-facing photovoltaic system, you were able to generate 3.15 kWh yesterday (10 kW system, continuously cloudy and/or drizzle). That’s enough to heat well during the day.

3.15 kWh harvested (10 kW system, continuously cloudy and/or light rain). That’s enough to heat well during the day. How so? My house has a standby consumption of 250-300 W for technology, ventilation, IT equipment, refrigerator, etc. I don’t think much less is realistic. With that, the winter photovoltaic output is already used up after 10 hours. And you haven’t even made coffee yet.
There certainly isn’t any photovoltaic power left for heating.

My house has a standby consumption of 250-300 W for technology, ventilation, IT, and refrigerator, etc. That sounds like a lot. I’m around 150-170 watts. Controlled residential ventilation, refrigerator, waterbed. IT is limited to router and switch.
Currently it’s 707 watts including some lights, heating, and TV/surround system.
By the way, today with some sun, the energy harvest was 7.87 kWh.
