Yes, a heat pump can often be used in combination with regular radiators, but there are some considerations to keep in mind. Traditional radiators operate at higher water temperatures than typical heat pumps provide, so adjustments may be necessary to allow the heat pump to function efficiently. Here are some points to consider:

1. Water Temperature:

   • Heat pumps generally supply hot water at lower temperatures than gas-fired heating systems. Traditional radiators are designed for higher water temperatures. This difference may affect the efficiency of the heating system.

2. Low Temperature Radiators or Underfloor Heating:

   • For optimal operation of a heat pump, it is often recommended to switch to low temperature radiators or underfloor heating. These systems can more efficiently deliver heat at the lower water temperatures that heat pumps produce.

3. Heat Demand Calculation:

   • A detailed calculation of the home's heat demand is necessary to determine whether regular radiators combined with a heat pump can provide sufficient heat. In some cases, additional measures may be necessary, such as increasing the surface area of the radiators.

4. Hybrid Systems:

   • Hybrid heating systems, which combine a heat pump with a traditional boiler, can be a solution. This allows the use of the heat pump for moderate temperatures and activates the boiler when extra capacity is needed.

5. Advice from a Professional:

   • It is highly recommended to seek advice from a certified installer or a heat pump specialist. They can assess the specific characteristics of your home and make recommendations for the most suitable heating system.
