THE radiator conversion to heat pump is a process that requires a specific upgrade of the existing heating system and is not exactly a "direct" conversion. Radiators and heat pumps work in different ways, but it is possible to their integration to work together, offering greater efficiency.

How are Heat Pumps Combined with Radiators?

1. Heat Pump with Hydraulic System
   If you already have a radiator system, you can add a air-to-water heat pump the geothermal heat pump and connect it to the existing plumbing system (pipes and radiators).
   • Heating: The heat pump will extract heat from the air (or the ground, if it is a geothermal pump) and heat the water, which circulates in the radiators and transfers the heat to the space.
   • Cooling: The same heat pump can also operate to cool the radiator, if the system supports reverse cycle operation (reverse pump operation).
2. Heating System Upgrade
   If your radiator system is not efficient enough to work with the heat pump (for example, if the radiator system is old and uses high water temperatures), it may be necessary to upgrade the radiators in larger or more efficient models which are capable of operating at lower water temperatures.
3. Low Operating Temperature
   Heat pumps are most efficient when operated with lower water temperatures (around 35-45°C). This may not be enough to heat a room with a conventional radiator which requires higher temperatures (60-70°C). That is why heat pumps work best with underfloor heating the larger radiators which allow heat transfer at a lower temperature.
4. Support From The Aerothermal Packager
   If the heat pump is air-to-air (or if you combine a heat pump with air heaters), then you will not need radiators, as the heat pump will directly supply warm air to the space. However, if you want to use radiators, then the best solution is to use an air-to-water heat pump or a geothermal pump.

Benefits and Disadvantages of Conversion

Benefits:

1. Increased Energy Efficiency: The cooperation of the heat pump with radiators can lead to significant energy savings compared to traditional heating systems (such as gas burners).
2. Environmentally Friendly: The use of heat pumps reduces CO2 emissions, as they use existing heat from the environment (air, ground or water).
3. Automatic Temperature Adjustment: With a heat pump, you can control the temperature in your home more precisely, and enjoy both heating and cooling when needed.

Disadvantages:

1. Initial Installation Cost: Installing the heat pump and adapting the system with radiators can be expensive, especially if major changes to the system are needed.
2. Requires Heating System Upgrade: If your radiators are not capable of working in low temperatures, you may need to replace or upgrade them.
3. Spatial Restrictions: Installing a geothermal heat pump requires space to place the pipes or boreholes, which may not be possible in confined spaces.

Conclusion

THE radiator conversion to heat pump It is not exactly a simple process, but adding a heat pump to a system that already has radiators is feasible and can offer many advantages in terms of energy efficiency and cost savings. However, the success of the project depends on the quality of the existing heating system, the requirements of the space and the type of heat pump chosen.
