Dear forum members,
I am new here and, to be honest, I haven’t read all the previous posts yet, so a similar topic might already be discussed.
We are a family with three small children and are fortunate to be allowed to build in our hometown near Regensburg. In 2011, we built a small 145 sqm (1,560 sq ft) Tuscan-style house, but unfortunately, it no longer meets our needs, so we are planning to build again. Our current home is heated with a groundwater heat pump including cooling (which we rarely use). Overall, we are satisfied with the heating results, although on cold winter days, I miss the comfortable “warm feet feeling” that I have experienced with friends who have pellet or gas heating. What bothers me more is that our hot water takes quite a while to heat up and only reaches a temperature where I can still comfortably keep my hand under it.
We are considering a pellet heating system, but to be honest, we haven’t really researched heating systems at all yet—and a lot has probably changed in the last eight years. Our architect has proposed a compact heat pump with a central ventilation system and hot water storage, as this would likely be cheaper than a pellet system with central ventilation. However, for the heat pump, we definitely do not want an outdoor unit. An indoor installation might be possible, but we have concerns about the noise.
Is a central ventilation system really necessary or required? Currently, we have a decentralized ventilation system, which works well overall, but I am quite bothered by the plastic covers inside, which have yellowed over time.
What are your experiences? Ventilation—yes or no?
Heating—pellet, compact unit, or something else?
Thank you very much!
Best regards, Stefanie

It's probably because most people don't really understand what photovoltaic systems are, how they work, and that they are cost-effective. In some new housing developments, photovoltaic systems are mandatory for new constructions. This should be implemented everywhere in line with the energy transition.

The payback period is usually between 10 and 15 years. Under normal circumstances, no one would invest otherwise. The advantage, however, is that the (low) return is relatively secure and predictable. A payback period of 10 to 15 years corresponds to a return of 6.66% to 10%.
And that return is _secure_, risk class 1, at most 2. Government guarantee thanks to the Renewable Energy Act.
Where else would you put your money, in Zamunda?!
For comparison: Today, buying or building an apartment in Munich is estimated to have a 40-year ROI. That is 2.5%.
Including risks (and opportunities) such as changes in property value, tenant turnover, tenant nomads, and so on. Minus management, maintenance, interest, etc.
Well, you can probably achieve a better return on the stock market, although the risk is slightly higher with a similar term. So that would be my preference, as you can start with any amount and act more flexibly. Plus, photovoltaic systems are worn out after 20 to 25 years. Then what?
Furthermore, there are many political plans currently in place, and overall, electricity prices are expected to decrease due to CO2 redistribution.
This will ultimately kill photovoltaic investments since the returns will disappear.
Conclusion: Photovoltaics mainly benefit companies, as they really achieve high returns.

Neither is the average (global) stock market return (historical, since no one knows the future) equivalent, nor does the risk category correlate.
Fail.

And photovoltaic panels are scrap after 20 to 25 years. So what then? Nobody knows. From today’s perspective: throw them away. They have generated excellent returns for 20 years.

Besides, many political plans are currently in place, and electricity prices are likely to fall due to CO2 redistribution. Protection of acquired rights. Promises made cannot be revoked. Constitution and so on.
The profitability of a photovoltaic system is completely independent of electricity price developments. I have already pointed this out to hampshire.
You buy a system today at price X and know very precisely what it will generate over the next 20 years, thanks to law. This is not a gamble. (Risk class 1)
For the residual risk, there are insurance policies that usually cost nothing extra for the average consumer because they are included if you ask.

That will finally kill photovoltaics because then the returns will be gone. It will be the exact opposite. Gas bills are going from €50 to €200 per month, and everyone else will be laughing.
That would at least be the rational strategy. The black scenario is trying to prevent this as long as possible. No alternatives.
That really makes your knees shake.
