Using air conditioning and central heating boiler side by side is the most efficient way of heating. Heating with air conditioning is cheap and you only heat the room(s) you use. Here are some tips to use both systems effectively:

Use boiler and air conditioner for heating
- Boiler for basic heating: Let the central heating system heat the home or office space at a fixed temperature so that the room does not get too cold. An air conditioner works best if the room does not cool down too much.
- Air conditioner as additional heating: Heating with the air conditioner on electricity is cheaper than heating with the boiler on gas. By using the boiler as basic heating, you benefit from the best comfort.
- Setting tip: Set the thermostat of the central heating system to 17-18 degrees and heat above that with the air conditioner. The lowest cost with optimum comfort.

Optimising energy efficiency
-Use air conditioning locally: Air conditioners are usually more efficient when used in separate rooms. For example, if you are only in the living room, use the air conditioner there instead of heating the whole house with the central heating.
-Do your solar panels still generate power in winter or are you still allowed to make use of the balancing scheme then make the most use of the air conditioning system for heating.

Comfort and cost management
- Optimal temperature: Try to set both systems so that they do not overlap or operate unnecessarily at the same time.
- Check your energy consumption: Since both systems run on electricity or gas, it may be wise to keep an eye on your energy consumption. The air conditioner's heat pump function is energy-saving, but for extremely cold days, you need the central heating boiler for optimal heating.

Maintenance and settings
- Regular maintenance: Make sure that both your air conditioner and your central heating boiler are regularly maintained to keep performing optimally. A well-maintained system works more efficiently and uses less energy.
- Smart thermostat: Consider using a smart thermostat that can control both systems. This can help make the right choices automatically based on the weather and your preferences.

Conclusion

How best to combine air conditioning and central heating depends on your energy tariffs and usage. Heat from the central heating system gives the best comfort but is often more expensive, heat from the air conditioner is cheap but often a bit less comfortable due to air currents present.
