The Electrolux EI30MH55GS Microwave oven can be mounted over high-performance cooktops, with up to 56,000 BTU of total heat output.
This Sharp microwave puts out 1100 watts of power which makes it fairly energy efficient, but provides sufficient energy to heat foods quickly.
With 28,000 BTUs, the Friedrich SL28L30* has the most BTUs.
4800 BTUs will 150 square feet.
A small room is about 5,000 BTUs. Most people don't have a room that would require more than 10,000 BTUs.
An HVAC system is rated in British Thermal Units (BTUs). For example, a 2-ton air conditioning system is 24,000 BTUs. That's 12,000 BTUs per ton. So a 3.5-ton air conditioner is a 42,000 BTUs.
90,000 BTUs - the 090 is what tells you the BTUs of the unit.
There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs
A 100 pound propane tank has a capacity of 2,160,509 BTUs
6,520 Btus
The answer depends on the city. Somewhere like Colombo (Sri Lanka) will probably require 0 btus.
A romm 20x9 is 180 square feet. You will need 5000 to 6000 BTUs for this.
To convert a watt to BTUs, the factor is 1 kilowatt of power = 3412.1416 BTU/hr 3.412 BTUs equal a watt. 1200 watt = 4094.4 BTUS you will need to remove about 4100 BTU/hr
