Heat pump or heated parquet - experiences?

Hello everyone

I am currently facing a heating decision for a house with a floor area of 35m2. It is to be expanded by a maximum of one room of about 12m2. Heating load approx. 6-7 KW. The roof (south side) is also developed. Windows will be replaced & later insulated. The goal is to be able to live there at least partially on a permanent basis (2-3 people) – so not just a weekend house. Gas, district heating, and pellets are excluded.

The following options are available:

Option 1
- Air/water split heat pump bwl 1s with Variotherm underfloor heating
- Wood stove
- Solar thermal later

Option 2
- Heat parquet
- Wood stove
____
Other considerations:

We looked at the heat parquet in a 120 m2 house. There, electricity costs of 100 euros per month were incurred for heating. At first glance, this seems to work very well.

Especially with option 1, one could use a wood stove with a water jacket and have a good combination with a small solar thermal system.

The construction costs are significantly higher with option 1, but operating costs are probably lower. Although with such a small house, operating costs are probably affordable for both options.

Practically, with option 2 it gets warm immediately and the installation is simpler and in particular requires less space.

It would help me a lot to get some advice and tips.

Thank you very much and best regards

35 m2 and 6-7 kw heating load is basically like completely uninsulated.

The 6-7 calendar weeks include the attic conversion and the extension. I phrased that a bit incorrectly.

Since you only have electricity or stove to choose from, I would prefer a heat pump/stove combo because you have a better efficiency than with parquet.

An air conditioner would also be an option.

However, you should not be deceived by the costs.

If you actually have 6-7 KW, you are roughly at the level of a normal energy saving regulation single-family house and thus also at the costs in this range.

Thank you for the assessment. Yes, in the long term, the heat pump/combination is certainly cheaper. The idea is to heat a lot with the stove in winter when it is really cold (which for us is a maximum of 14 days in the wine-growing region, there is practically no snow). The heat parquet probably sounds too simple and good to be true.
