Floor Temperature Vs Air Temperature

Radiant heat can play a significant role in achieving thermal comfort promoting a healthier home environment and lowering economic heating costs.

Floor temperature vs air temperature.

The air on the ceiling will be the temperature of the ceiling. In cold weather a concrete slab is almost always colder than the surrounding air and epoxy will immediately take on the temperature of the slab once it is applied. Thermal mass in a heated shop or hangar floor responds rapidly to the change or air temperature when a big overhead door is opened. But don t forget to warm the slab s surface using heat lamps portable heater or hot air blower.

The best range of temperature is 50 to 80 degrees f. The rising column of air out of the panel radiator counters the cold air flow and the temperature of the surface of the panel radiator is higher than a section of radiant wall and the air space between the back side of the radiator and the wall keeps the temperature that the insulation is working against much lower too. The finished floor surface temperature is what the building occupants feel when walking on the floor affects the rate of heat radiating into the air above the floor and if too high can also become a safety concern. The air in the room is only one part of a matrix of thermal flux paths.

Consider the slab temperature with the material at a pleasant temperature and the ambient temperature everything will run smoothly. For floors occupied by people with normal indoor footwear flooring material is insignificant. That 30 degree window isn t very big especially when working outside in the summer months. According to cmhc canadian mortgage and housing corporation the finished floor temperature should never exceed 85 f 29 c.

All the heat that has been trickled into the slab over time is released quickly to combat the cold air rolling over the floor. The floor walls and ceiling all play a part by setting the boundary conditions. At the optimal temperature 6 of the occupants felt warm or cold discomfort in the feet. This happens because of the sudden dramatic increase in temperature difference.

Fundamentally the air on the floor will be the temperature of the floor. Olesen 1977b found an optimal temperature of 77 f for sedentary and 73 5 f for standing or walking persons. Extreme hot or cold temperatures will cause the sealer to dry too fast or too slow. In order to understand how radiant heat makes these benefits possible we must first clarify the difference between ambient air temperature in the home as opposed to the mean radiant temperature.
