Heated Concrete Floor Tubing

June 17, 2021

If concrete needs to be wheeled across the floor, simply lay down some plywood planks to spread out the weight and protect the tubing. If your slab will be 6″ thick or more then you should plan for more tubing for a quicker response time.

This is the stateoftheart method of installing hydronic

Check out this picture from a recent milmar build project of all the tubing laid down for a three zone heated floor:

Heated concrete floor tubing. The boiler heats the water up to about 90 to 130 degrees fahrenheit, which in turn warms the floor surface. Since the concrete slab installation is fairly simple, many people fail to follow some simple yet very important steps thinking that it will work no matter what. The acceptable temperature range is determined by the type of flooring and the tubing material used.

Radiant underfloor heat costs less to heat your home than any other type of heating system by being able to lower the thermostat temperture while still staying toasty warm. The tubing should be spaced about 10″ on center so multiply your area by 1.25 to come up with the right amount of tubing. Placing tubing too deep in the slab will increase response time, which means it will take longer for the floor to reach the desired temperature, will result in increased btu load, require more energy and possibly will require larger tubing diameter.

When installed in a concrete slab, radiant underfloor heating is very efficient and comfortable. Radiant heat with pex or electric rolls is the most efficient heating system available. The heating contractor laid out the pex tubing according to the zones that were established for heating the home.

If your building is not well insulated then order a slightly larger kit and space the tubing a little tighter. Installation of the radiant floor system in a wood frame building usually requires that a layer of lightweight thermal mass material be used to cover the tubing (such as concrete, gypspan, gypcrete, etc). The picture above shows a concrete floor we're about to pour with radiant heating tubes installed.

Those systems are most commonly hydronic, meaning heated liquid is pumped through tubing in the concrete which the… Concrete height above pex adds additional r value, and while it’s minimal in most instances, more energy would be required to heat the topmost surface. Supply requirements will vary from job to job.

Typically, a large crack in the concrete slab has compromised the tubing, resulting in multiple leaks. See more ideas about pex plumbing, diy plumbing, plumbing. Concrete floors are very popular in lofts and other contemporary homes.

This pex in floor kit is used for up to 1500 square feet floor with a typical layout. Sometimes the tubing and reinforcing mesh gets lifted into the thickness of the slab as the concrete is placed. Here’s an excellent video in which the narrator is installing a heated floor inside the foundation of a morton buildings frame of unknown dimensions.

Even more common than that, is the lack of proper insulation underneath the slab. The pex tubes were attached to wire mesh using zip ties. You can look at our learning center for more info or info & links on this page.

With ½ tubing a circuit length of 300' is standard, but circuits anywhere from 250' up to 350' are within the range recommended by the radiant panel association. This makes the total cost of a heated concrete floor between $14 and $31 a square foot installed. When installing radiant floor heat tubing in a concrete slab in new construction there should not be an issue with tubing bending radius nor spacing constraints.

Anyone who has installed hydronic floor heating surely has watched as their neatly placed tubing circuits get buried in concrete. If the slab was poured properly, the tubing will be under the concrete, not in the concrete. People just can’t afford to pay the operating cost for a system that.

Radiant heating systems are very common in concrete floors now because they provide a very balanced and comfortable distribution of heat. Pex tubing should have a minimum of 50 mm (2 in.) of concrete over the top of the tubing. “a radiant floor heating system simply radiates heat upward from the floor to provide optimum comfort and many other benefits.” benefits of heated concrete floors.

Installing pex tubing for concrete slab underfloor heating is one of the easiest ways to install radiant heat. Just snap the tubing in the grooves. A comeback for foam radiant floor icf forms heated with air tubes.

Concrete costs between $4 and $6 a square foot to pour. They can be polished to a high shine, stained various colors, or left natural.

A solar/radiant floor combination system can be installed in any type of building or any type of construction, including slab on grade, suspended concrete slab or wood frame construction. The way i see it you have 2 choices 1 spend the 350 and see exactly where those lines are 2 find your floor layout and measure the distances between the loops and drill maybe youll get lucky and not hit the line maybe you will hit the line then spend a $ 1000.00 to smash the concrete up , repair the line then pour new concrete if it were me the 350 sounds easier and cheaper All we know is, it’s big.

Other times the masons trample over the tubing and mesh as if it’s not even there. The concrete was 4 thick and the insulation under the slab was 2 thick.
