Unlike radiators that take up valuable wall space floor heating pipe is hidden under the flooring, making it an efficient and discreet way to heat your home. The pipes are surrounded by concrete or gypsum making them durable and resistant to temperature and pressure changes. These pipes also need to withstand freezing conditions, and be resistant to corrosion. That’s why it is important to use only high-quality floor heating pipe for your UFH system.
The most common type of piping used in radiant floors is PEX (polyethylene) with an oxygen barrier. It is the most cost-effective and durable piping for radiant systems. Compared to copper, PEX is not only more affordable but it will last much longer with minimal maintenance requirements. The plastic is flexible which makes it easier to install and doesn’t degrade, rust or leach chemicals into your water supply like metal pipes can.
To determine the proper size of your piping consider several factors:
1) The desired heat output from the radiant floor system.
2) The size of the room:
3) The climate where the space is located:
If you are in a climate with lower temperatures you may want to opt for wider piping. Or if you have high heat loss, you may need to go with closer spacing to increase your thermal performance. Always consult with professional HVAC engineers or reputable floor heating systems providers for recommendations specific to your building or project. These experts will consider your specific heating requirements, regional regulations and manufacturer specifications to ensure your radiant system is designed for the optimal installation and performance. floor heating pipe
