One of the more frequently asked questions I’m asked is “how long will it take for my room to warm up with infrared heaters?” Our infrared heaters reach their full temperature within 5-10 minutes, meaning that the direct warmth which you feel emanating from the heaters happens quickly. This effect is static, in other words you feel the warmth from the heaters no matter if the air around you is hot or not. It is analogous to how you can feel the sun’s warmth on a clear day, regardless if it is winter or summer.
How long it takes for the air temperature of your room to reach a certain level is a much more difficult question to answer. Below are 5 factors that play a significant role in determining this:
Total Wattage
The amount of energy (wattage) that is pouring into your room affects how quickly the air temperature will increase. More wattage equals a quicker warm up time.
Cubic Feet
The cubic feet of your room (length, width, height) relates to the warmup time. A larger room with the same amount of wattage will take longer to heat.
Delta
The delta, or change in temperature, influences the warm up time. For example, to go from 75 to 95 degrees will take significantly less time than from 65 degrees to 105 degrees, all other factors being equal.
Insulation
How well insulated a room is plays a very significant role in the warmup time. Lack of adequate insulation in the walls and/or ceiling is the biggest culprit of delayed warm up times when studios have adequate wattage (input of energy) for their space.
Climate
Outside temperature influences how quickly an inside room will warm up, especially in rooms with exterior walls and windows. For this reason, the warmup time is actually a moving target i.e. it will be considerably shorter in the warmer months compared to the colder months!
For a room that is already built out, the ways to expedite the warmup time come down to either increasing the energy input, increasing the insulation, or decreasing the delta.
I hope this helps and please reach out anytime with questions.
