The cost comparison between electric heating with solar panels and gas heating depends on various factors, including the efficiency of the heating system, energy prices, investment costs, and the energy consumption of the specific system.

Here are some considerations:

1. Electric Heating with Solar Panels:

   • If you have solar panels, you can use self-generated electricity to heat your home. This can be advantageous, especially on sunny days when the solar panels produce a lot of energy. However, the costs depend on the initial investment in solar panels, the efficiency of the heating system, and the total energy consumption.

2. Gas Heating:

   • Gas heating can be efficient and traditionally has lower energy costs than electric heating. However, the costs depend on the price of natural gas, which can fluctuate. There are also environmental issues associated with the use of fossil fuels.

3. Investments in Solar Panels:

   • The initial costs of installing solar panels must be factored into the calculation. Solar panels have a payback period, and the financial benefits depend on factors such as local sunlight hours, energy prices, and possible subsidies.

4. Energy Efficiency of the Heating System:

   • The efficiency of the heating system is crucial. Electric heating systems vary in efficiency, and some heat pumps can be more efficient than traditional electric radiators.

5. Energy Prices:

   • The costs of electricity and gas vary by region and over time. It's important to know the current energy prices and consider possible price fluctuations.
