Heat pumps can work with existing radiators, but some considerations are essential to ensure optimal performance. Air source heat pumps operate by transferring warm air from the outside air temperature to warm up your home. When it comes to using existing radiators with an air source unit, a few factors need to be taken into account:

Compatibility: Traditional radiators are often designed to work with higher-temperature systems like gas boilers. Air source heat pumps generally operate with lower-temperature water. While heat pumps can work with existing radiators and gas boilers, it’s important to assess whether your existing radiators can efficiently distribute water at the lower temperatures produced by the ground source heat pump.

Sizing and Surface Area: Radiators with larger surface areas are better suited for the air source unit. This is because heat pumps work most effectively when distributing water over a larger surface area at lower temperatures. If your existing radiators are not appropriately sized (too small), it might be necessary to consider resizing or replacing them for optimal performance.

Professional Assessment: To determine whether your existing radiators can work effectively with an air source heat pump, it’s recommended to consult with our professional installer. We can evaluate your current system, assess the compatibility of the traditional heating system with the new unit and recommend any necessary changes.

Modifications: Depending on the assessment, your existing radiators might need changing to enhance their performance with the lower temperature output of a unit. This could include adjustments to the radiator sizing and rebalancing the existing system.

Can I use radiators with an air-source heat pump?

Yes, it can be used and heat pumps can work with them. But it’s important to choose heaters that can handle the lower temperatures. For the best energy economy, you should increase the size of all radiators in your house and warm every room that can work with lower water temperatures.

What kind of radiator is needed for a heat pump?

It’s important to consider the lower temperature output radiator that can effectively distribute water at these systems.

Here’s what you should look for:

1. Low-Temperature Capability: A radiator which can work at lower-temperature is equipped to provide a flow temperature with adequate heat output, producing water at temperatures of around 40-55°C (104-131°F).

2. Larger Surface Area: larger surface areas are better suited. Since heat pumps and radiators work the best when distributing water over a larger area at lower temperatures, radiators with large surface space enhance efficiency and performance.

3. Modern Panel Radiator: These radiators are designed to have low temperatures and provide efficient water distribution at lower temperatures.

4. Compatibility with Heat Pump Controls: Consider radiators that can work seamlessly with the controls of your new unit. This compatibility ensures that you can optimize the performance and energy efficiency of your property.

5. Underfloor Heating (UFH): UFH systems are another excellent option to consider with heat pumps. UFH distributes water evenly across a room, operating at the lower 55 degrees Celsius temperatures favoured by heat pumps. It can often be used in combination with radiators for comprehensive solutions.

6. Cast iron radiators:

Cast iron radiators are known for their ability to retain and radiate heat over an extended period. While they can work with heat pumps, they might take longer enough heat to reach the heat pump engineer desired temperature due to the lower temperature output of the heat pump.

Radiators must cater to low-flow temperatures

One critical aspect of using radiators is their ability to cater to low-flow low flow temperatures. Heat pumps operate most efficiently when the water temperatures they produce are lower than 55 Celsius. Radiators that with heat pump technology can emit sufficient heat pump work at these lower temperatures are essential to ensure both energy efficiency and comfortable heating.
