Author One of the strengths of Radiant heat is its ability to deliver heat without delivering noise. A properly designed radiant heating system is the epitome of silence. The gas or oil burner on the boiler is often the only component that makes any detectable noise, and it’s usually located in the mechanical room away from the occupied spaces.
How to install radiant tubing ?
Radiant heat is one of the most comfortable forms of central heating. If you’re building a new home or an addition to a home, it’s easy for a do it yourself type to install radiant heating before pouring the concrete slab. No special tools are needed and the most important thing to remember is not to let the heating tubes cross each other when installing them.
you need to invest in proper tools for the job. Depending on the job, you will need to purchase PEX tubing of adequate length, along with PEX cutter and crimp tools. You will need crimp rings to affix the pipes and fit them tightly.
Chek fittings tools used and First Cut the tubing into loops of not more than 300 feet in length. Any longer and the heat will dissipate, creating cold spots.
Connect the leading end of the radiant heat tubing to the heat supply of the radiant heat system. Lay the tube out along the floor, the length of the room and then turn it back on itself at the other end of the room. As you lay the tubing in parallel lines, take care not to let the lines of tubing cross or touch. Continue looping the tubing about 4 to 6 inches apart in parallel lines until you get near the other end of the 300 foot length. Attach this end of the tubing to the return section of the radiant heat system (the part of the system that collects the cooled liquid to be reheated and re-circulated). Both the heat supply and cool return should be centrally located in the area you are installing the heat tubing.
Use special tubing twist ties to secure the tubing to the rebar. Tuck the edges of the twist ties under the rebar so they do not poke up through the concrete slab after it is poured.
Attach a new 300 foot length of tubing to the heat supply and install the same way as the first length in Step 3. Continue until the entire floor area is covered with tubing, placed in parallel lines approximately 4 to 6 inches apart.
