Hello!
We are planning to have a house built and are currently still in the initial planning phase. However, after a conversation with the architect, we are already considering heating options.
We are not building a KfW-certified house, but one strictly following the Energy Saving Ordinance. It will have about 220m² (2,368 sq ft) of living space plus a basement.
In various building specifications from contractors (we are having a turnkey build), we often see heat pumps that require an additional outdoor unit beside the system in the utility room. For aesthetic reasons, we are not very keen on that.
What alternatives are there for this kind of setup?
Gas heating combined with solar (the gas connection is available)?
Geothermal heat pumps?
Or other air-to-water heat pumps that do not require an outdoor unit?
We will probably have a hipped roof (with regard to solar panels). With a flat roof, the panels look quite unattractive.

However, I assume that is not possible without solar collectors, right?

Sascha_aus_H4 Jun 2017 17:53Yes, it is possible. We are even building to KfW55 standard using gas and without solar panels. It is well insulated and features controlled ventilation, so there should be no issues without the KfW requirement.

It takes forever to adjust the temperature effectively. Especially during weeks with large outdoor temperature fluctuations, this is quite uncomfortable. The underfloor heating always lags behind.
.If outdoor temperatures affect the interior faster than the underfloor heating can compensate, there is an issue with the building envelope.

R.Hotzenplotz4 Jun 2017 17:55We also want to have a controlled residential ventilation system.
Whether the building envelope is good or not, we will only find out once the construction contract is in front of us and we have it reviewed.
Currently, we live in an apartment in a two-family architect-designed house, about 5 years old. There, we are experiencing these problems with the heating system.

Complete nonsense. In my opinion, a radiator belongs in a child's room, not underfloor heating!
Example:
The daughter does her homework in her room (21°C (70°F)) and then wants to go to sleep right afterwards... then she needs 17°C (63°F)... This is not achievable with underfloor heating! It is too slow to respond!

R.Hotzenplotz4 Jun 2017 17:58We can’t even reach 17°C (63°F) here, even in the middle of winter, when the underfloor heating is completely off. In the bedroom, it is off all year round, but the temperature always stays above 17°C (63°F).
Is it actually possible to use a heat pump together with radiators?
