UFH pipes are the backbone of any water underfloor heating system, working to connect the system together whilst transferring hot water around the complete installation. Choosing the right type of pipe is crucial to ensure a hassle-free installation and a quality end result. UFH pipes are available in a range of sizes, options and lengths to suit all types of projects and installations.
Generally, there are three main types of pipe that can be used for hydronic underfloor heating systems; copper, PEX and stainless steel. Each pipe has different characteristics that make it suitable for underfloor heating, however PEX piping is fast becoming the most popular option due to its durability and ease of installation.
The size of the pipe has a huge impact on the heat output and energy efficiency, as does the spacing between the pipe runs. In general, it is recommended that pipes are spaced 150mm to 200mm apart depending on the room and floor constructions.
A key factor is the tube diameter as this directly impacts the hot water flow rate and therefore heat output. Typically, larger diameter tubes are required for underfloor heating as they can accommodate a higher volume of water than smaller tubes. In addition, the spacing between the pipe runs can be affected by factors such as the floor construction, insulation, floor surface and heat loss values. This is why it is important to carefully calculate your underfloor heating system before starting. Underfloor heating pipe
