Even though underfloor heating systems are generally highly reliable, there are many common problems that these systems can experience.
These problems may range from incorrect system setup to incompatible external parts such as flooring.
Some underfloor heating problems may also be as simple as trapped air in the pipes. Generally, HVAC issues often come down to the pipes. If your underfloor heating system is a wet system operating from a boiler, it may be trapped air or a blockage. Fortunately, you can fix these issues easily as they occur. Blockages may sometimes occur and cause issues within your underfloor heating. There may be twigs, leaves, and other debris blocking your flue vent that leads to the outdoors of your home. During winter, in extremely cold weather conditions, your discharge pipe may freeze, preventing your underfloor heating system from functioning when you need it the most. Trapped air is among the most common problems your system is likely to experience, especially if it uses hot water flowing through a sub-floor pipework. Air may get trapped in the pipe and remain there, causing problems within your entire system. This problem may occur during the installation process. If your system is installed already, you may eliminate the trapped air by bleeding your underfloor heating system. Experiencing leaks is also a common problem. If your system keeps losing pressure, it indicates the possibility of a leak. When the pressure levels drop, it may be caused by the connecting pipes to the manifold not connected properly, causing the leaks. Also, if you have an incorrect setup, which is a common problem, it may hinder your system from functioning correctly.
