browsing through this forum, I’m quite embarrassed by how deeply everyone else has already delved into the subject, while I am still just at the very beginning.
We would like to build a bungalow that is fairly energy-efficient. The house design, roof shape (single-sloped roof fully facing south), and room layout are planned for multiple uses and optimal utilization. I’m less interested in KfW considerations, as they sometimes seem more like creative accounting (at least that’s my impression). We want to build using prefabricated components (timber frame construction) and do so without harmful substances. There are not many options left regarding the selection of materials and companies. Photovoltaic panels are planned for the roof, 1-2 wind turbines in the quite large garden (yes, there is a lot to consider there), and possibly an additional solar system to support heating.
Now to my problem: where can I get independent advice on the best possible heating system for our house within my ideas, without relying on a specialist? Experts from manufacturer X or Y only promote their own products.
We don’t mind whether it is underfloor heating or wall-mounted radiators. We do NOT want fossil fuels, and neither geothermal or groundwater probes (i.e., drilling or similar) are an option. I also find a fireplace unappealing, as I view such things less romantically and more functionally/ cost-consciously. Ideally, the heating system should be integrated with or complement a mechanical ventilation system, as otherwise I would be concerned about mold and moisture in such a highly airtight house.
Thank you for your suggestions.

stefanika11 Mar 2015 19:46But air is a poor heat transfer medium, right? Regarding my question about who could advise me, do you have any suggestions?
Yes, air is definitely the least efficient option, but if you don’t want geothermal energy or fossil fuels, there really aren’t many alternatives besides air...
And since you want to combine the ventilation system with the heating system, this is actually the best starting point for a warm air heating system... otherwise, how would the water in the wall heating or underfloor heating be warmed up?
The only option left is the air source heat pump, but I would not want to pay the electricity costs in winter... in my opinion, these units simply consume too much energy, especially if you want it to be WARM.
