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?

Numbers more like
- what is the initial cost
- what energy consumption levels were recorded during winter
- at what indoor temperatures
- which ventilation system (NAT) is used
- how is domestic hot water produced and what additional consumption does that cause
- which cooling system is possibly needed, or how is shading implemented
So question 1 would be answered with 8k. What type of hot water system is installed?
I do believe it can feel quite comfortable. But how does it feel when it’s -15°C (5°F) outside? The window must have very good performance then, right?

That the whole thing doesn’t add up mathematically without misusing a photovoltaic system in a simplistic calculation has already been discussed extensively here over more than 42 pages.
I can’t be the only one who noticed that in this very old thread, a brand-new user suddenly appeared who had never contributed before, happens not to be good with numbers, and just happens to be extremely happy with their window heating.
Nightingale, I hear your footsteps...

Dear Kati, I’m no nightingale! We happened to come across the heating windows. They are offered as standard with Talis-Haus. However, since Talis was not willing to accommodate our other special requests – (and like most prefab home companies) – we ended up building ourselves and ordered the windows from Vestaxx. We are simply satisfied customers (yes, those still exist occasionally). Sometimes you just have to give something a try. I’m too old to be a dreamer... And I just can’t understand why such a great idea is so poorly calculated! We haven’t yet gone through a full winter, so I can’t provide exact figures. Hot water is produced with instantaneous water heaters, which also works well. No issues with Legionella! Any more questions?
Come on, share the numbers. How long have you been living in the house, and what energy consumption figures have you had so far? We can also compare month by month. The heating season is over. In a new build, except in mountain lodges, heating is no longer necessary.
I would like to put this statement into numbers.

And with fan heaters for half that cost again. Everything else like the house, photovoltaic system remains the same.Similar topics
