Wärmepumpe oder Gas?

I have a house that I want to expand. Currently, I heat it with a chimney, but I am considering whether it would be better to switch to a heat pump or gas. I would like to know your experiences and opinions on this topic. Personally, I believe that transitioning to a heat pump could be more beneficial. A heat pump is more environmentally friendly as it uses renewable energy and emits fewer harmful substances into the atmosphere. Additionally, operating costs for a heat pump may be lower compared to gas. However, there are several factors to consider. Firstly, the cost of purchasing and installing a heat pump may be higher than in the case of gas. Additionally, suitable conditions for heat pump installation, such as access to land or water, need to be provided. If you have access to natural gas from the grid, installing and using a gas boiler may be easier and cheaper. It is also important to consider local conditions and availability. If obtaining gas supply from the grid is difficult in your area, it may be more practical and cost-effective to install a heat pump. The final choice between a heat pump and gas depends on your individual preferences, budget, and local conditions. It is worth consulting with an expert who can accurately assess your situation and advise the best solution.

Or maybe an accumulation water tank (buffer) + photovoltaics, but off-grid without an inverter with a direct current heater.
