How Heating Systems Heat A Room

  • Wall Radiators (similar to baseboard heaters)
  • Forced Air (Typical Furnace)
  • Warmboard (Floor Heat)

 * Radiant Slabs are all about thermal mass; Consider the 1/3 loss of thermal mass under hardwood flooring?


Radiant Slab Floor – Prepared For Installing Hardwood Floors

(Gypcrete – Lightweight Concrete)

Photo Example For Hardwood Flooring Location

What it takes to install Radiant Slab Heat

Prep-Work & Material not required when using a Warmboard


Additional Engineering

(This cost should remain the same unless you add the slab after engineering.)


Stronger, more expensive floor joist and support beam $???

(This cost could be substantial pending the final engineering.)


Add Blocking – Between studs (Every gap between studs) $???

(Additional 2 X 4’s needed, Additional Labor to install blocking.)


Build curbs at stair openings $???

(Additional 2 X 4’s needed, Additional Labor to install curbs.)


Build curbs at elevator shafts $???

(Additional 2 X 4’s needed, Additional Labor to install curbs.)


Install 2 X 4’s in areas where Hardwood Flooring is installed $???

(Additional 2 X 4’s needed, Additional Labor to install curbs.)


Seal all penetrations $???

(Gypcrete or lightweight concrete slurry will leak through any penetration into the level below.)


Slabs are never exactly level and/or consistent


Requires much hotter water to provide heat.

(Staple up heating tube water temperature range 160˚ – 180˚ Gypcrete water temperature range 140˚-160˚)

 Wood is an Insulator. (R-1 per/inch)

In the photo above, for every 32 square feet of sub-floor – 11.66 square feet or 1/3 of the thermal mass is lost. $???

OPERATING TEMPERATURES (Floor Heating Types)

Gypcrete or Lightweight Concrete (Slab Heat)  Operating Water Temperature 140˚ – 160˚

Warmboard Operating Water Temperature 115˚ 10% -20% Comparative Savings

Staple Up

(Underfloor heat tubing)

Operating Water Temperature 160˚ – 180˚
