How long does PEX last in concrete? PEX tubing can last for several decades when installed in concrete, with an estimated lifespan of 40-50 years or more. However, this can vary depending on factors like insulation and climate. How many BTU per square foot for radiant floor heat? A rough estimate is 20-30 BTUs per square foot for residential radiant floor heating. How thick should a slab be for radiant heat? The concrete slab for radiant heat should typically be at least 4 inches thick to ensure proper heat distribution. However, larger tubing sizes may be needed for larger or high-heat-load areas. What size PEX should I use for radiant heat? For residential applications, 1/2-inch PEX tubing is commonly used.

What is the best tubing for radiant floor heat? PEX (cross-linked polyethylene) tubing is commonly used for radiant floor heating due to its flexibility, durability, and resistance to corrosion. What is the maximum length of a radiant heat loop? Radiant heat loop lengths can vary based on factors like tubing size and heat output, but a rough estimate might be around 300-400 feet per loop. The specific layout depends on factors like room shape and size. How do you layout radiant tubing? Radiant tubing is usually laid out in a serpentine or loop pattern across the subfloor, ensuring even coverage of the heated area. It’s typically installed directly on top of the subfloor, followed by insulation (if needed) and then the finished floor covering. Should radiant heat go above or below subfloor? Radiant heat should go below the subfloor. However, this can vary depending on factors like tubing size, heat load, and floor covering. What is the proper spacing for radiant floor heating? Typical spacing for PEX tubing in radiant floor heating is about 6 to 8 inches apart. A common rule of thumb is to aim for around 20-30 BTUs per square foot for residential applications. Factors like the size of the room, insulation, outdoor temperature, and desired indoor temperature are considered. How do you size radiant heating? Sizing radiant heating systems involves calculating the heat load of the space you want to heat. As a rough estimate, you might cover about 150-200 square feet with 300 feet of 1/2-inch PEX tubing in a typical layout. How many square feet will 300 feet of PEX cover? The coverage area of 300 feet of PEX tubing depends on the spacing and layout. Typically, tubing is laid in a serpentine or loop pattern with even spacing between runs, covering the entire heated area. How do you layout radiant floor heating? The layout of radiant floor heating involves placing PEX tubing or heating cables in a pattern across the subfloor to evenly distribute heat. Set the flow rate and desired temperature.Īccount for tubing expansion and contraction.Įnsure compliance with local codes and standards.
