Hello, we plan to start building our own home this year. For various reasons, we want to work with a provider that offers a complete service package. Currently, we are deciding between Fischer Bau and Helma.
About our house:
We are about 95% sure that it will be the house shown in the attachment (attachment: image from the provider Fischer Bau).
We aim to achieve KFW70 standard. No basement, underfloor heating throughout the house, blinds all around, additional towel radiator in the bathroom, brick facade, and a hip roof with a dormer.
The plot is located in a village; the roof area (with dormer) probably faces south-southeast.
I have been researching and reading about all aspects of building a house for some time now. So far, I have been quite interested in the air-to-water heat pump. It seems to be a good and reliable heating system that is somewhat future-proof. However, the more I have looked into air-to-water heat pumps, the more negatives I have found.
Both providers initially proposed a gas heating system with solar panels in their basic offers. However, upon my inquiries, both also offered an air-to-water heat pump with ventilation and exhaust air heat recovery as an alternative.
At the moment, I am quite unsure what the best heating system for our house is. Many statements about air-to-water heat pumps, such as them being very noisy and inefficient, come from the years 2010–2012. I am not sure if that is still accurate. Gas is basically not bad either, a solid heating medium with mature technology.
I hope to receive some comments and suggestions here on how best to approach this. I think ventilation and exhaust ventilation are important today since houses are very airtight, and one cannot or does not ventilate as often as needed.
But gas? Solar? Air-to-water heat pump?
I am somewhat overwhelmed by the information, and I really can’t find any independent or unbiased advice.
