Hello,
We are planning to build a house, hopefully by the end of the year, and I have already started considering the type of heating system.
It will be a single-family home of about 150sqm (1,615 sq ft) located near Bremen. Currently, there are two of us, but a child will be arriving soon.
After several hours of research on Google and forums, I believe that an air-source heat pump combined with a photovoltaic system and battery storage is the most practical solution. For coziness, a stove is also planned for the living/dining area.
Advantages: no costs for gas connection or gas supply, no expenses for drilling and permits, increased efficiency through self-generated electricity with storage, and you can earn money by feeding surplus energy into the grid. Also, it provides some cooling effect in the house during summer.
Disadvantages: higher initial investment compared to a gas heating system, increased electricity costs in winter when it gets really cold.
My main concern is whether the higher electricity consumption might offset the savings from not using gas. Are there other disadvantages I might have overlooked?
How much more expensive is a photovoltaic system with a battery approximately compared to a conventional gas heating system?
Does the stove support the heating system in any way, or does the heating system maintain its temperature regardless of how warm the room gets?

But photovoltaic systems are not free either; they have purchase and later maintenance costs. People, there is no free lunch. Until proven otherwise, I still consider a gas boiler in a properly insulated house combined with underfloor heating to be cost-effective. Since you are basically required to install some kind of eco-friendly device, we opted for solar thermal for hot water, which is the most affordable option upfront. Starting from the vernal equinox on March 21, I turned off the heating; our hot water is now provided solely by the solar system until the end of September. This also saves several cubic meters of gas.
