Need a better idea of how much heat is required for your space? Use the tool below to assist you in determining how much wattage or Btu/H are necessary for your circumstance.
|DELTA T (Temperature rise over outside ambient) - choose from below|
|INSULATION FACTOR - choose from below||5°||10°||15°||20°||25°||30°||35°||40°||45°||50°||55°||60°||65°||70°||75°||80°||85°||90°|
|INSULATED (POST-YEAR 2000)||0.970||0.195||0.292||0.389||0.486||0.584||0.681||0.778||0.876||0.973||1.070||1.167||1.265||1.362||1.459||1.556||1.654||1.751|
|ANSWER = ACTUAL CUBIC FEET X MULTIPLIER FROM TABLE ABOVE|
|1. DETERMINE CUBIC FEET OF HEATED SPACE. (LENGTH X WIDTH X CEILING HEIGHT OF THE ROOM)|
2. DETERMINE DELTA T (Temperature rise over outside ambient air temperature or supplemental temperature increase)
|3. CHOOSE INSULATION CATEGORY FROM ABOVE.|
|4. GO ACROSS ROW TO THE COLUMN WITH THE APPROPRIATE DELTA T.|
|5. TAKE THE MULTIPLIER X THE CUBIC FEET AND THE ANSWER IS THE APPROXIMATE WATTAGE NEEDED.|
|6. TO CALCULATE THE Btu/H EQUIVALENT, MULTIPLY THE WATTAGE BY 3.412.|
|EXAMPLE: There is an 800 cubic foot space that needs to be heated. The minimum outside ambient temperature is 0° F. A comfortable temperature of 70° F is the target. In this example, the Delta T would be 70° F. The space is characterized as insulated. The 800 cubic feet would be multiplied by a factor from above, which, in this instance, would be 1.503. The resultant answer would be 1202.4 watts. So any design, be it a baseboard heater, wall heater, etc., would be an appropriate choice, if the wattage rating is equal to or exceeds this figure.|
