Radiant Floor Pex Spacing

5 8 barrier pex can be used for larger projects where high btu load is present due to lack of proper insulation larger than normal slab thickness or special project considerations.

Radiant floor pex spacing. Pex is an acronym for cross linked polyethylene a plastic tubing installers use for hydronic radiant heating systems. Dwg dxf it will note the manifold location and the routing of the tubing across the floor indicating flow direction spacing and overall loop length. The 7 8 durapoly xl pex is a large diameter tubing. Radiant floor company will provide a detailed worksheet for your project explaining the amount of tubing in each zone the spacing gallons in the floor heat loss pump size and setting etc.

We can also provide drawings to assist with your pex installation we will however need scaled. The simplest way to determine the amount of pipe you will need is to first choose the appropriate tube size and spacing for your application then determine the overall lineal. To increase the floor output for selected tubing size and length the flow may need to be increased the tubing spacing may be closer together or an increase in water temperature. The tubing layout is a cad drawing of your floorplan showing the layout of your radiant floor tubing.

Prior to laying and installing pex tubing circuits a thorough plan and system design must be completed in order to carry out installation faster precisely and to avoid making costly mistakes. It is potable and ultraviolet resistant for protection against sun damage during installation. 1 2 oxygen barrier pex is the most popular size used for radiant floor heating in both thick and thin slabs. We can create a new floor plan or lay the tubing drawing on top of an existing cad file.

And this is used in conjunction with our installation manual installation video and website information. A diagram of the system will be helpful in the future as well should a need arise to repair the system and to avoid damage during overall residence remodeling or renovation. For example by increasing the flow through 1 2 pex tubing by only 0 1 gpm floor output will increase at 5 btu sq. With 7 8 xl pex you can expect a heat output of at least 50 btu s per foot in a slab on grade installation and 40 btu s per foot in a floor joist application.

This size is adequate for all small to medium size jobs both in residential and commercial projects.
