A good size home of about 1500 sq ft would need about 80,000 btu to heat it effectively on a very cold day..the area you live in and how well the place you are heating is insulated will determine how effective 5118 btu will heat any given area...So 5118 btu heater would most likely heat a 100 sq ft room as long as it is closed off and is insulated good. if you figure 80,000 btu will heat a home of 1500 sq ft and the heat will not have to run contuinously..it would take 53 btu to heat 1 sq ft of space...with this in mind you will see that your heat will only run maybe 10 to 15 minutes per hour depending on the outside temperature...the colder it is the more it will run...the warmer it is the less it will run..
1500 watts is equivalent to 5118 BTU per hour. 1500 watt-hours is equivalent to 5118 BTU.

The size of the area that a portable air conditioner will keep cool varies depending upon the number of BTU's the unit has. For example, a 12000 BTU air conditioner will cool an area between about 500-600 square feet while a 8000 BTU air conditioner will cool an area of approximately 300-350 square feet.
Usually, depending on a few other factors, you need 20 to 22 btu per square foot. Higher ceilings and more windows require more.12000 btu should cover about 550 to 600 square feet of space.
11800 BTU/hr is 3.46kW
77,550 BTU/hr = 22.728kW
The amount of BTU's per square foot varies. The BTU's per ft2 in my area is 30-35. In your area there might be more or less. For reference sake... Btu's are not used in Metric settings, Joules are used. 1 btu = 11356 joule Contact a HVAC tech in your area. They can tell you the recommended BTU or JOULE rating for your area with the use of a manual known as a "J manual" +++ To be proper, BTU should be all capitals as in the first sentence, though correct abbreviations are very awkward to use in many Microsoft applications!
Almost 340,000 BTU per hr
BTU's (British Thermal Units) and two dimensional area are not compatible measurements.
This depends on the cost per kilowatt hour in your area.
It takes about 55 BTU'S It takes 180 BTU'S to raise 32 degrees to 212 degrees.
