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

If you buy photovoltaics for a heat pump, you could try drawing a coordinate system.The photovoltaic system pays for itself purely through feed-in, without even using any electricity, with a considerable return. The answer is therefore always: go for it, as long as it’s not a strangely shaped roof or there are severe shading issues.
If things go wrong, the feed-in tariff will be discontinued next year. Until then, the rule is: install as much and as large as possible directly on the roof. South, southeast, and west orientations up to 45° have proven to be economically viable purely based on the feed-in tariff within a maximum of 12 years.

And painting a house is a completely different technical challenge compared to planning a heating system... We did a lot of work ourselves, really, but even we wouldn’t have dared to tackle that... For the next house, just be brave. You can find plenty of support online, including examples and ready-made plans from other homeowners. You just need to understand the plans and be able to explain them to convince and find the tradespeople who will then carry them out in your interest.
I took on the heating system without any prior knowledge and otherwise managed to avoid doing much myself. Everything else I tried ended up costing more and taking longer.
I still don’t understand the benefit of having photovoltaic panels that produce a lot of electricity in the summer when I don’t need it, but I do need it in the winter. Unless I have air conditioning.
We were looking at an investment of 15,000 (currency) and calculated that it would eventually pay off, although I can’t remember how many years exactly… 12 or 15 or so.
But that calculation didn’t take into account any breakdowns. So we decided to just prepare for batteries as long as they are still expensive and we don’t have an electric car.

We would have invested 15KThat would be a massive system, well over 10 kWp, if you have that investment. Gross, it would be more than €18,000 (about $19,500). With that, you could buy a 13-16 kWp system. Respect for your original plan.Similar topics
