Air Source and Ground Source Heat Pumps and Underfloor Heating SoleHeat



Underfloor heating systems have surged in popularity as a highly efficient and comfortable method to heat homes. SoleHeat specializes in leveraging the latest technology in air source and ground source heat pumps to power underfloor heating systems, offering an eco-friendly, cost-effective solution for your heating needs. This article will delve into how underfloor heating works when integrated with air source or ground source heat pumps and provide insights on why this combination could be the ideal heating solution for your home.

How Underfloor Heating Works:

Underfloor heating is a method of heating indoor spaces by running heated water through pipes or electric heating cables beneath the floor surface. The heat from these pipes or cables rises to heat the room evenly, providing a comfortable living environment without the need for traditional radiators. When paired with air source or ground source heat pumps, underfloor heating systems become even more energy-efficient and environmentally friendly.

Air Source Heat Pumps and Underfloor Heating:

Air source heat pumps (ASHPs) extract heat from the outside air, even in cold temperatures, using a refrigerant cycle. This heat is then increased in temperature through compression and transferred to the underfloor heating system's water circuit, warming up the floors and the room above. ASHPs are known for their efficiency, as they can produce significantly more energy as heat than they consume in electricity. This makes them a perfect match for underfloor heating, providing consistent and cost-effective warmth throughout your home.

Ground Source Heat Pumps and Underfloor Heating:

Ground source heat pumps (GSHPs) operate on a similar principle to ASHPs but extract heat from the ground using a network of water pipes buried underground. The ground maintains a relatively constant temperature throughout the year, making GSHPs incredibly efficient for heating purposes. The extracted heat is then used to warm up the water in the underfloor heating system, providing a stable and eco-friendly source of heat. Due to their efficiency and the consistent temperature of the ground, GSHPs paired with underfloor heating can offer even greater energy savings and environmental benefits compared to ASHPs.

Benefits of Combining Heat Pumps with Underfloor Heating:

  1. Energy Efficiency: Both ASHPs and GSHPs convert energy from the air or ground into heat more efficiently than traditional heating systems, leading to lower energy bills and reduced carbon emissions.
  2. Even Heating Distribution: Underfloor heating distributes heat more evenly across rooms, eliminating cold spots and creating a more comfortable living environment.
  3. Space Saving: Without the need for radiators, you have more freedom in designing your living spaces.
  4. Lower Operating Temperatures: Heat pumps are designed to work efficiently at lower temperatures, making them ideal for underfloor heating, which requires a lower temperature than radiators to heat a room effectively.


Integrating underfloor heating with air source or ground source heat pumps offers an efficient, sustainable, and comfortable heating solution for modern homes. SoleHeat is at the forefront of this technology, providing expertise and high-quality systems designed to meet the specific needs of your home. Whether you are building a new property or retrofitting an existing one, considering this combination could lead to significant energy savings and environmental benefits.
