Hello,
We are starting to get really frustrated... every builder tells us something different...
We want to build a 130sqm (1,399 sq ft) KfW 70 house with the living room facing south, and we are unsure whether to choose gas or an air source heat pump. Some providers, at almost the same price level, offer us air source heat pumps and claim that the annual costs are significantly (30%) lower compared to gas, while others doubt this.
We understand that insulation with gas/solar systems is usually better because an air source heat pump boosts efficiency more towards KfW 70 standards compared to gas/solar, which might argue in favor of gas. An air source heat pump might fail somewhat sooner, and in case of problems, you can usually get quick and competent local support with gas. With air source heat pumps, there could be more difficulties. Additionally, the noise of air source heat pumps (in our case about 3 meters (10 feet) from the neighbor) is not insignificant. Some say that sooner or later, everyone ends up having issues with neighbors for this reason.
We are interested in air source heat pumps with storage tanks from these providers: Vaillant, Mitsubishi Zubadan, and Rotex.
What we are really curious about is the annual cost for heating and hot water with both systems.
We live near Kassel.
What should we choose, and what would be cost-effective TODAY? What is your opinion on Vaillant?
Regards
Gigi

Guaranteed, plenty of everything from the dynamo to immersion heaters and even Tesla transmitters when it comes to electricity.

Hello,
Of course, there are many other options as well. The question that needed to be clarified is which heating system suits the planned building best. I also believe that the basis of any planning should be a reliable assessment of one’s own behavior. Unfortunately, this self-assessment is often missing because it is not really supported by the builders, who also lack the experience. Therefore, especially for building services engineering, it is advisable to first consult independent planners or specialist contractors before deciding on a system.

.... That’s why it’s important to first get advice from independent planners or specialist contractors regarding building services before deciding on a system. Amen to that! However, most naïve buyers are not very interested, probably because it might cost a bit of money. They are more likely to believe the exaggerated marketing claims of the respective salespeople. Very few are aware of the economic impact of such a decision, but then again, how could they be, given the lack of necessary expert knowledge. Best regards.

specific question: Where can I find a good planner for heating, hot water, and ventilation for a single-family house to be built in 41812 Erkelenz?
Thanks and regards
