Hello everyone,
My husband and I attended the open house of a wooden house builder from the region (Schleswig-Holstein) today and got to know the Vestaxx window heating system there.
Is there anyone here who has experience with the Vestaxx window heating system?
At first, it sounds strange to have the heating in the windows. For the triple-glazed windows, an invisible layer is applied on the back of the innermost pane using nanotechnology, which heats the pane via infrared up to 40 degrees and warms the room. The warmth actually felt very pleasant, and the windows were indeed ice cold on the outside today (<10 degrees). Allegedly, the Vestaxx window heating system transfers 92% of the heat to the room, and TU Berlin has tested this Vestaxx window heating system and rated it well. It has only been on the market for a short time.
Overall, I find it quite interesting, significantly cheaper than other heating systems, you can control every room individually, and unlike underfloor heating, it is very agile.
Of course, it only makes sense in a low-energy house (the wooden house builder prefers 40+), as it is powered by electricity. In this case, the Vestaxx window heating system is said not to consume much electricity.
This is the impression from the fair; naturally, they want to sell it.
What are your experiences with Vestaxx? Have you heard of this system before? Is it an alternative to conventional heating systems? Does it have a future?

This Vestaxx window heater might make sense in small bathrooms?

Otherwise, a heat pump is of course significantly more efficient.

That probably only makes sense with large windows. At 40 degrees, a normally sized window is probably not sufficient for an average room.

I have no experience with the Vestaxx window heating system. I would rather be concerned about what happens if the heating in the window breaks. Does that mean a new window is needed? but you don’t have to reinvent everything.

I hadn’t known that until now, the report about it is quite interesting. However, that doesn’t mean I necessarily wanted to do it, but I am always interested in innovations. Of course, there are various other options for a heating system that suits you, for that you should especially find out what is important to you when it comes to heating. But you should also inquire seriously outside of this forum. For example, we didn’t want a water-based underfloor heating system or screed and would have preferred stylish radiators. However, we don’t have gas connected. what speaks against trying something new? without wanting to judge this heating type, what happens if the water-based underfloor heating has a leak or the heat pump malfunctions or, or.

200 watts per square meter of glass. With 6 heating hours per day and an electricity price of 30 cents per kWh, that amounts to 36 cents in heating costs. With a correspondingly low heating load (e.g., 2 kW), that is 3.6€ per day or 108€ per month. Thus expensive in ongoing operation. I have no Vestaxx window heating experience regarding acquisition costs and service life. Disadvantage: For hot water, you need an additional device, ideally a domestic hot water heat pump. Then the advantage you may have in the acquisition shrinks again. You need screed and insulation underneath anyway.

Insulation yes, screed no.
At our place, the domestic hot water heat pump has been running properly for 2 weeks now, depending on the situation I can also imagine an electric instantaneous water heater. I recently saw that at acquaintances, but as said, these things definitely depend on individual needs or usage behavior.
