80,000 btus (british thermal units) should heat up 3,500 square feet

Standard practice holds that it takes 5000 BTUs to heat a room 100 to 150 sq ft Figure on adding another 1000 BTUs for every 50 or so sq ft added. Hence , 400 to 450 sq ft would need about 10,000 BTUs
It will vary on the room type and construction. However you can assume you want 10-15 watts of energy per square ft. That would mean you want 2500-3750 watts total, which would be 8,500 - 12,750 BTU's (3.4 BTUs/Watt).References:How_many_square_feet_does_a_5000_BTU_heater_heathttp://www.diychatroom.com/f18/btus-watts-35066/

4800 BTUs will 150 square feet.
how many square feet will 26,000.00 heat
about 12,000
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.
The answer depends on the city. Somewhere like Colombo (Sri Lanka) will probably require 0 btus.

A small room is about 5,000 BTUs. Most people don't have a room that would require more than 10,000 BTUs.
