If your house is not suitable for a heat pump, there are various options and considerations you can take into account:

1. Hybrid Heating System:

   • Consider a hybrid heating system, which is a combination of a traditional boiler and a heat pump. This system can switch to the most efficient heat source based on the outside temperature and energy prices.

2. Energy-Efficient Measures:

   • Implement energy-efficient measures in your home, such as improved insulation, using energy-efficient windows and doors, and sealing cracks and gaps. This can reduce the heat demand and increase the potential for a heat pump.

3. Low Temperature Heating:

   • Consider using low-temperature heating systems, such as underfloor heating or low temperature radiators. These systems work well with heat pumps and make it more efficient to use lower water temperatures.

4. Energy Advice:

   • Have an energy assessment carried out by a professional. An energy advisor can assess the specific characteristics of your home, identify possible energy-saving measures, and make recommendations for the most suitable heating system.

5. Alternative Sustainable Technologies:

   • Consider other sustainable technologies, such as a solar water heater or biomass boiler, as alternatives to a heat pump.

6. Financial Considerations:

   • Evaluate the financial aspects and available subsidies for different heating options. Some systems may be more expensive initially but might have lower operating costs and subsidy benefits.

7. Future Possibilities:

   • If a heat pump is currently not feasible, consider preparing your home for future sustainable technologies. This might mean that you can easily switch to a more sustainable heating system in the future.
