Vestaxx window heating - experiences?

How did the heat feel – similar to an infrared panel, which already becomes significantly warmer as an object?

The heat was very pleasant. It is infrared after all. It’s probably also nice if you plan a window seat ;)

I am now trying to get in touch with a builder who has installed the system and uses it under real conditions. Especially to see what the actual power consumption is and whether it can be covered by photovoltaics even in this weather.

But as I said, this system is mainly offered in combination with a low-energy house and as large photovoltaic system as possible.

It's also via infrared.

I estimate the infrared component to be rather low. The temperature is far too low for that.

I am now trying to get in touch with a builder who has installed the system and uses it under real conditions. Especially to see what the actual electricity demand is in the end and whether it can be covered by the photovoltaic system even in this weather.

Hello, have you already been able to gain experience from real operation? We are also planning to build a house from the manufacturer and are currently planning with Festaxx.

Hi, no, not yet. We are currently still waiting for a (hopefully positive) response to the application for a building plot. After that, we would go deeper into the planning. Due to the current Corona situation, a visit to a builder on site is also rather difficult, I hope it looks better next year. But if you have already gained new insights in the meantime, I would be happy if you share them with us.

Hm, well I am not convinced by electric direct heating from an ecological and economic perspective. Even if you could produce most of the electricity yourself with a large photovoltaic system, significantly more electricity is consumed than with a heat pump. This means that you use your entire photovoltaic yield for heating and cannot sell it. Or use it to charge an electric car. Even if the feed-in tariff is no longer very high, you still get a few cents for the electricity sold.

And from an ecological perspective: If I don't need all the photovoltaic electricity myself, at least another household can use my "green electricity." However, if I use all the electricity in my electric heater, that is not possible. Then it is simply consumed.

Hm, well, I am not convinced by direct electric heating systems from an ecological and economical point of view.

I am also grateful to those innovators whose inventions I individually consider (partially gross) nonsense: even something as downright nonsense as the non-hybrid electric car makes a valuable contribution through the pressure of innovation it radiates, ensuring that developers of other technologies do not stand still.
