around 400 SF, not ft
Having this: 400 sqf/ ton and 1 ton= 12000 BTU/h The area to be heated is 162,000 sqf so 162000/400= 405 tons 405 tonsx12000=4'860,000 btuh Converting 4'860,000 btu to watts=1424325.24 watts/hr to heat a 162,000 sf area Regards
On average it takes about 1,600 BTUs to heat 50 square feet. Multiplying 50 by 1600 equals about 80,000. Therefore, the heating plan of 1,600 square foot are would take about 80,000 BTUs.
Many variables but for normal conditions 100 btu will be plenty
12000 BTUs/Hr. Coverage 550 sf
Do not go by the basic heat calculation. Have a Hvac company come in and do a heat calc. They take into account, insulation, wall thickness, windows, area. This will give you the best size furnace to use. Ask the company if they use heat calc software, and that you would like a copy of the calc. This way you know the calc and also that they did not just take the sq ft of the home and just come close to a #.

600 spf A good general rule of thumb is 20 BTU per square foot. So, a 200 sf room would require a 4000 BTU ac unit. If you use 20btu per square foot to determine the required tonnage, you will be under sizing your system. For example 20btux1500sf=30000btu. There are 12000 btu per ton so you are using a 2.5 ton system to cool 1500 sf. On a hot summer day your electric meter will be spinning like a tilt-a-whirl at the county fair. Your air conditioner is designed to run at it peak performance when the ambient temperature is 95 degrees or below. When the ambient heat or heat index exceeds 95 degrees you a/c is working harder and running longer. When sizing an a/c system you should take into consideration the summer climate where you live. In Texas we use 500 sf per ton as a rule with homes that have 8 foot ceilings, however walls with western exposure, windows facing the west (sun set) and vaulted or high ceilings should be considered in your determination. In commercial application you use 400 sf per ton, but you also factor the number of people occupying the space, equipment that generates heat and the amount of make up air that is required. 0sf-750 sf= 1.5 ton 751-1000sf= 2.0 ton 100sf1-1250sf=2.5 ton 1251sf-1500sf=3.0 ton 1501sf-1750sf=3.5 ton 1751sf-2000sf=4.0 ton 2001sf-2500sf=5.0 ton
110,000 btu Since British Thermal Unit deals with volume rather than area, we need to know the height of the ceilings. The original answer probably (and sensibly) assumes standard 8' ceilings. Hate to sound like a nitpicker, but many of today's homes have at least one room with a "cathedral" or vaulted ceiling. My previous home had "Saltbox" architecture; at one place in the great room (which comprised 1/2 the house's total square footage) reached a height of 42' sloping to 8' in front and 35' in the rear. The total square footage of the house was ~1700, where the cubic footage must have been almost 3 times that of a standard 1700 sf house.
128 sf is 14.2 sq yards.
