Why the air source heat pump is working best with the underfloor heating?
Air source heat pumps (ASHPs) work particularly well with underfloor heating (UFH) systems due to their operational characteristics and the way the UFH distributes warmth. Here’s why air-source heat pumps are a great match for underfloor heating:
1. Lower Operating Temperatures: UFH systems operate at lower flow temperatures compared to traditional radiators. The air source heat pump excels at providing heat at these lower temperatures, making it a natural fit for UFH, which is designed to work optimally with such conditions.
2. Efficient Heat Distribution: UFH systems cover a larger surface area, distributing heat more evenly throughout a room. This aligns with the air source heat pump design to provide consistent, steady heat output, enhancing overall comfort.
3. Longer Running Cycles: Air-source heat pumps tend to operate more efficiently when they run for longer periods at a steadier pace. UFH systems have a slower response time compared to radiators, allowing the air source heat pump to maintain steady cycles, achieving higher efficiency.
4. Comfort and Even Heating: UFH provides a pleasant and consistent warmth across the entire floor area. Air source heat pumps complement this by producing a lower flow temperature heat required for underfloor systems, ensuring a comfortable environment without sudden temperature fluctuations.
5. Optimal COP Performance: The Coefficient of Performance (COP) of an air source heat pump improves when it operates at lower temperatures. Since an underfloor system demands lower heat supply temperatures, ASHPs can achieve higher COP values, resulting in better efficiency.
6. Reduced Energy Consumption: The combination of the air source heat pump and the underfloor system typically results in reduced energy consumption compared to conventional heating methods. The ASHP’s ability to efficiently produce heat at lower flow temperatures aligns with the underfloor system requirement, resulting in energy savings.
7. Renewable Central Heating: Underfloor systems are often compatible with renewable energy sources like ASHPs. Using a renewable heat source like an air source heat pump enhances the overall sustainability of the heating system.
While the air source heat pump works well with underfloor heating, it’s important to ensure proper system design, sizing, heat loss calculation, and professional installation. The air source heat pump output capacity and the underfloor heating system design need to be matched appropriately to achieve optimal performance and efficiency. Consulting with our heating engineer can help ensure that the installation of the air source heat pump and underfloor heating is effective for your specific needs.
