ᐅ District heating KfW55 - KfW70 costs of the ventilation and exhaust system

Hello everyone,
we are planning a bungalow.
We initially chose KfW 70 because the payback period for KfW 55 is quite long (the installed equipment requires maintenance, can break down, and partly also consumes electricity). The highway is located about 500 m (550 yards) from the property, and despite the noise protection forest, it is still relatively loud, so we want to plan a ventilation system (probably without heat recovery) to ventilate with closed windows.
Today, I found out that the property where we want to build will be supplied with district heating.
The costs are: a one-time fee of €9,500, a base annual price for 2017 calculated at €450 (this may change later), and energy costs of 5.2 Ct./kWh (this may also change later). The formulas for price changes are included in the contract (not yet signed), but they are not easily understandable for everyone.
There is an advantage here: the primary energy factor is 0.43 (certified and valid until 2024). The contact person at the energy supplier (municipal utility) told me that KfW 55 standards can only be met with increased thermal insulation compared to KfW 70 (without additional measures).
What are your opinions on the resulting maintenance costs, experiences with district heating, and KfW 70 versus KfW 55?

If you haven’t read the post completely, I agree with you.
So again, it’s not about just one topic.
Here, you either ask a question, answer questions, or simply want to get various information 😉
But now you are creating an unnecessary discussion, and that is not the purpose of this.
