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?

SaniererNRW1238 Oct 2022 09:13I want to bring up a completely different aspect: sustainability, taxonomy, ESG, and the building energy law.
Do you really believe that electric direct heating (no matter the type) has a future? I would bet that this kind of heating will be banned in the not-too-distant future, which would put an end to all the recurring discussions here. The energy consumption is simply too high. Maybe it will still be accepted as an emergency solution in passive houses. Nothing more than that.

No, the calculator doesn’t lie: 23,000 × 3.5% = 805 × 20 years = 16,000

Here is the answer in a much simpler way. Yes, you miscalculated.
The interest would be €9,013, but it can be completely ignored since the increase in electricity costs is also not taken into account.
If that is also around 3-4% per year, it balances out.

Christian 658 Oct 2022 09:44I believe the best approach is to generate your own electricity, so the electricity price becomes irrelevant.
Ideally, you produce enough so that you don't have to buy any. Feed-in tariffs or compensation rates are already very low.
However, a large photovoltaic system is definitely expensive.

RotorMotor8 Oct 2022 09:48This has already been discussed countless times. There isn’t much photovoltaic power available in winter, and the roof area on a single-family house is naturally limited.
