Heat Pumps for Heating and Cooling • The system allows even heating throughout the whole floor, not just in localized spots as with wood stoves, hot air systems, and other types of radiators. • The room heats from the bottom up, warming the feet and body first. • Radiant floor heating also eliminates the draft and dust and allergen problems associated with forced-air heating systems. • With radiant floor heating, you may be able to set the thermostat several degrees lower, relative to other types of central heating systems. • There are no heat registers or radiators to obstruct furniture arrangements and interior design plans. Disadvantages • Does not respond quickly to temperature settings. • Relatively expensive to install but can save money in a long run. • Requires professional installers. 5.9.2. Heated Thin Slabs Another common method of installing floor heating uses a “thin slab” (e.g., 1.5-inch to 2-inch slab thickness) poured over a wooden floor deck. Because the slab is thinner than with slab-on-grade floors, it has slightly less heat dispersal characteristics. This translates into a slightly higher water temperature requirement for a given rate of heat output compared to that required for a slab-on- grade. This difference is slight. A 1.5-inch-thick concrete thin slab with 12-inch tube spacing and covered with a finish flooring resistance of 0.5oF•hr•ft2/Btu yields about 8% less heat output than a 4-inch-thick slab with the same tube spacing and finished flooring. This can be easily compensated for by using 9-inch rather than 12-inch tube spacing. The following guidelines are reommended: 80PDF Image | Heat Pumps for Heating and Cooling
