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?

How did the heat feel – similar to an infrared panel that clearly gets warmer as an object?
The warmth was very pleasant. It’s infrared after all.
It’s probably also nice if you plan a window seat 😉
I am now trying to get in touch with a homeowner who has installed the system and uses it under real-life conditions. Mainly to see what the actual power consumption is and whether it can be covered by photovoltaics even in this weather.
But as mentioned, this system is primarily offered in combination with low-energy houses and as large a photovoltaic system as possible.

It's also based on infrared.I estimate the infrared portion to be rather low. The temperature is much too low for that.V

We are also planning to build a house from the manufacturer and are currently in the planning phase with Festaxx.

EinHausfür57 Dec 2021 11:50Hello, no, not yet. We are currently still waiting for a (hopefully positive) response to our application for a building plot. After that, we would proceed with more detailed planning.
Due to the current COVID-19 situation, visiting a builder on site is also quite difficult; I hope it will improve next year.
But if you have already gained new insights in the meantime, I would be happy if you could share them with us.

Grobmutant7 Dec 2021 12:22Hmm, I’m not convinced about electric direct heating from an ecological and economic perspective.
Even if you have a large photovoltaic system and can produce most of the electricity yourself, the consumption is significantly higher than with a heat pump.
This means you end up using your entire photovoltaic yield for heating and can’t sell any surplus electricity or use it to charge an electric car. Even though the feed-in tariff or payment for surplus electricity isn’t very high anymore, you still receive a few cents for the electricity you sell.
From an ecological point of view: If I don’t need all the photovoltaic electricity myself, another household can still use my “green electricity.” However, if I use all the generated electricity for my electric heating, that’s not possible. Then the electricity is simply consumed.

Hmm, well, I am not convinced by electric direct heating from an ecological and economic perspective. I am also grateful to those innovators whose inventions I personally consider (sometimes quite seriously) nonsense: even something as obviously flawed as the non-hybrid electric car makes a valuable contribution by exerting innovative pressure that motivates developers of other technologies not to stand still.
