Monolithic Slab Floor With Radiant Heat

14 years later still in good shape and seems to keep house warm and comfortable.

Monolithic slab floor with radiant heat. These questions answers on problems with radiant heated floor slabs were posted originally at radiant heat mistakes be sure to see the discussion there. The workers in the photograph at page top where our concrete slab. Faqs on radiant heat floor mistakes to avoid. This article explains how to avoid some fatal mistakes when installing radiant heat in a concrete floor slab by describing an incompetent radiant heat floor installation along with an explanation of why things went wrong and how to avoid these errors.

Remember that your slab will be about 75 degrees f. In summer the concrete pulls heat in and radiates it into the room making the hvac system work harder. In 1973 it has a concrete slab foundation with radiant heat water runs thru copper tubing within slab. Heated slabs on grade will feature hot water pipes or coils embedded within or beneath the slab to provide space heating.

A slab on grade floor that is not a heated slab on grade floor. Concrete is an excellent thermal conductor which is another way of saying it s a poor insulator. Some installers will say it is safe to install widths up to 3 inches but smaller widths will have less overall movement in response to the radiant heating. If your slab is heated it s a good idea to increase the r value of the vertical and the horizontal insulation to at least r 20.

The thickness of the slab does not have to change because of radiant floor heat. We wanted a wood floor and spent a lot of time talking to flooring experts. Later which can undermine a monolithic slab. Mainly heated slabs radiate outward rather than downward so insulation on the edges of the slab is most important.

We were told the only way to go was a wood engineered floor glued down. On 2018 05 20 by mod what insulation or construction details will permit us to insulate the perimeter of a concrete floor slab. Any cooler surface in contact with the slab will try to steal its heat. The radiant heat that emits through the slab can wreak havoc on hardwood flooring pieces that are greater than 2 25 inches wide.

I do like to see a 6. The insulation phase is crucial for a radiant floor. Heat losses from heated slabs are greater than that of unheated slabs because the temperature is warmer. Compared to forced air heating it is approx 30 better.

The base you normally use under does not need to be changed. Slabs that include embedded hydronic tubing for radiant heat always need a continuous layer of horizontal insulation under the entire slab.
