Vestaxx window heating - experiences?

I would really be interested in some numbers regarding this claim! So a few pipes in the screed are supposed to require more energy in production than the manufacture of heated windows + 4 times the consumption over the lifetime! Interesting...

But now this is a completely forced marketing of a system. Every heat pump already has a built-in direct electric heater to cover peak loads. The additional installation effort is zero, nada, niente. For a window heater, you first have to run connections to all windows. Since you certainly don’t want a surface-mounted installation in the living room, you tear open the walls in old buildings for that. That alone makes the window heater pointless in old buildings. On top of that comes the surcharge compared to normal windows and the need to control two heaters. The heat element of the heat pump regulates itself automatically based on the outside temperature. Sorry, but I absolutely see no advantage here for old buildings. The scenario duplicates an existing system and causes additional effort and costs. We (actually) only market in new builds, but I get several calls or emails daily from customers who want to do something in their old buildings. I also advise them against our heating system if they don’t insulate the building envelope beforehand (and that generally includes the windows). I still want to face myself in the mirror in the morning. But people hope that just replacing the windows with heated glass is the solution. Unfortunately, it is not. And customers have usually already inquired about the cost of a heat pump. Then prices for a heat pump including underfloor heating of €80,000 from "reputable" heating installers reach the customer. That never adds up. If the system has a justification, it is only in new buildings where the energy demand is low and the additional wiring is not a big effort. But I still don’t see where the decisive advantage over normal infrared heating lies. Incidentally, these then radiate 100% of the energy into the building, and if a panel breaks, I can just go to the hardware store, buy a new one, and replace it. With the window heater, one can only hope that the provider still exists in 20 years. And when the windows are due for replacement, the window heater goes out with them.

I am new here and don’t know how to display a user’s reply like you do. Maybe someone can give me a tip. THANK YOU

The advantage over normal IR heaters is that we work with a nominal heating glass temperature of 43 degrees -> best comfort class. IR panels operate in the range of 60 - 120 degrees C. You or your child can burn your fingers there and cannot stay close for long because it becomes uncomfortable (cf. patio heaters). In addition, no wall space is consumed.

Should a glass really break, a window fitter comes with a new glass (so you don’t have to go anywhere) and is gone again after 15 minutes. Glass replacement is that quick.

And when the windows are due for replacement again ... after 20 - 30 years ;) ... then you just buy the frames and replace the glass - it's called sustainability ;)

I would be more worried whether spare parts for my heat pump will still be available in 20 years and what they would cost then.
