Radiant floor pex spacing.
The 7 8 durapoly xl pex is a large diameter tubing.
It is potable and ultraviolet resistant for protection against sun damage during installation.
How to install pex tubing for a radiant heat floor.
How to determine pex tubing size and spacing for your project there are several ways to size an rht pex tubing and manifold kit for your shop hangar or residence.
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 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.
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.
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.
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.
The tubing layout is a cad drawing of your floorplan showing the layout of your radiant floor tubing.
And this is used in conjunction with our installation manual installation video and website information.
For example by increasing the flow through 1 2 pex tubing by only 0 1 gpm floor output will increase at 5 btu sq.
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.
This size is adequate for all small to medium size jobs both in residential and commercial projects.
We can also provide drawings to assist with your pex installation we will however need scaled.
We can create a new floor plan or lay the tubing drawing on top of an existing cad file.
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.
