we have purchased a semi-detached house from a developer. In total, the developer is building 8 semi-detached houses and one detached house. All the semi-detached houses will have a split water-source heat pump. Our semi-detached house has one gas line, and we were offered to use this line for a gas heating system with solar without extra cost.
The semi-detached house has a basement but no finished attic. The living area is about 130m² (1,400 sq ft) with underfloor heating installed throughout.
Which option should we choose, or which one is more economical considering the running costs?
Best regards,
AndiTanja

In the end, it’s a matter of calculation.
What do gas and (heating) electricity cost in your area? And how high are the respective base fees?
For the heat pump, you need to consider two scenarios: one with Hamburg electricity without a base fee and one with heating electricity.
And is photovoltaic an option? At least in summer, you can use it with the heat pump to heat your water (but no more, regarding the heating part!).

Probably gas, if the pipeline is already installed.
However (just a guess):
In the long term, I would lean towards electricity. Electricity is politically supported, gas is not. Electricity can be generated from various energy sources, while gas is limited (natural gas + biogas – anything else?). Electricity prices are less prone to speculation, making price fluctuations lower. Generation costs have been quite stable for years, only the tax burden is increasing. Electricity and heat pumps also require comparatively little maintenance, and you can avoid having a chimney if you don’t want a fireplace purely for decoration.
