TUBING

All of our tubing is made in the USA and comes with a Lifetime Guarantee!


Engineered Radiant Heating Tubing
Many companies use tubing that was designed as water line.
Click here to read why that may not be the best choice and to learn about the advantages of an engineered tubing.



5/8" HIGH PERFORMANCE RADIANT PEX TUBING
NSF rated & UV protected
5/8" diameter, rated at 120° F @100 psi
200', 250', 300' coils
Crosslinked Polyethylene Tubing
This tubing is part of our "High-Performance" line of tubing that was developed under grant support from the U.S. Department of Energy many years ago. Its larger size and slightly thinner walls means that it will put out more heat than many other tubes. In addition, it is relatively easy to work with, is long lasting and saves on electricity needed for pumping. It is ideal for slabs, joisted floors and retrofit applications. Its higher performance allows the system to operate at a lower temperature for higher efficiency. Because of its thinner wall, this tubing may or may not be accepted by local codes.
Lifetime Guarantee.

5/8"PEX TUBING
NSF rated & UV protected
5/8" diameter, rated at 180° F @100 psi
ASTM 877/876 designation
200', 250', 300' coils
Crosslinked Polyethylene Tubing
This is tubing is similar to the 5/8" High-Performance but it has a thicker wall for higher pressure and temperature ratings. Because of this, the tubing isn't quite as efficient as the 5/8" High-Performance but it does put out more heat per foot than ½" Pex. This tubing is relatively easy to work with and is ideal for slabs, joisted floors and retrofit applications and has excellent code compliance.
Lifetime Guarantee.

7/8" HIGH PERFORMANCE RADIANT PEX TUBING
NSF rated & UV protected
7/8" diameter, rated at 120° F @100 psi
200', 250', 300' and 400' coils
Crosslinked polyethylene tubing
This tubing was developed with grant support from United States Department of Energy many years ago. Its larger size and slightly thinner walls means that it will put out more heat than many other tubes. It has the lowest overall cost because of this higher efficiency. It is not as maneuverable in small spaces as other tubes.
Lifetime Guarantee.

Non-Barrier, $.71/ft
Oxygen Barrier, $.82/ft

1/2" PEX TUBING
NSF rated & UV protected
1/2" diameter, rated at 180° F @ 100 psi
200', 250', 300' and 400' coils
A smaller tubing with a thicker wall. A stronger tubing with higher temperature and pressure ratings. It is easier to work with and has good code acceptance. Its limited heat output means that it must be spaced closer together. More tubing will need to be installed and the project will have a higher overall cost.
Lifetime Guarantee.

1/2" PEX OXYGEN BARRIER TUBING
Available in 250' and 300' coils
Lifetime Guarantee.

Non-Barrier, $.36/ft
Oxygen Barrier, $.47/ft

3/8" PEX TUBING
3/8" diameter, rated at 180° F @ 100 psi
Available in 300' coils
Available in oxygen barrier and non-oxygen barrier.

Insulation

Crete-Heat Insulation
The Crete-HeatTM Insulated Floor Panel System is an easily assembled modular board insulation, vapor barrier and radiant tube holding grid. It allows for simplified installation of hydronic radiant floor heating systems in basements, garages, main floor slab on grade and above grade installation where concrete or gypcrete is normally used.
The Crete-HeatTM Insulated Floor Panel System is 2 7/8" overall in thickness, with 2" of solid extruded polystyrene foam providing an R-10. Our retrofit or above grade panel provides 2 1/8" overall in thickness, with 1" of solid extruded polystyrene foam providing an R-6.
Each interlocking panel covers up to 8 square feet with fasteners for 1/2", 5/8", 3/4", or 7/8" radiant tubing. A 10-mil polystyrene film provides the vapor barrier.
Please call to order so shipping can be calculated to your location. For more info, please go to www.crete-heat.com
