It depends on the climate and how well your home is insulated.A good rule of thumb is about 20 BTUs per square foot.
Before purchasing a portable air conditioner it is important to determine how big of an area you want to cool. After you determine that, you can choose the correct size that you need because an incorrectly sized portable AC with insufficient or excess BTUs will result in inefficient cooling.
The "Mr. Heater F232000 MH9BX Buddy" portable propane heater has one of the highest BTU outputs for a portable heater, at 9,000 BTUs. If you need even more heat output, industrial propane heaters can go up to 400,000 BTUs or more for larger spaces.
A small room is about 5,000 BTUs. Most people don't have a room that would require more than 10,000 BTUs.
Perhaps the highest btu available in a portable air conditioner is 14000 BTUs. The air conditioner that has this high btu is the Sunpentown WA-1410H, which is portable.
A BTU is the amount of energy required to raise the temperature of 1 pound of water 1 degree Fahrenheit (F) at or near 39.2 degrees F and 1 atmosphere of pressure. Electric heaters are rated in KW, not BTU's 3413 BTU's = 1 KW-hr. Check the link below for a PDF on water heater sizing.
You will need a portable air conditioner that offers 24,000 - 25,500 BTUs to cool a room of about 1500 cubic feet. This is a large sized room and a 2.5 ton unit would cool that area.
There is no direct conversion between voltage (such as 110 volts) and BTUs (British Thermal Units), as they measure different characteristics. Voltage measures electrical potential while BTUs measure energy. To determine the BTU output of a device using 110 volts, you would need to know the specific device's power rating in watts, which could then be converted to BTUs.
With 28,000 BTUs, the Friedrich SL28L30* has the most BTUs.
To convert BTUs to tons, you can use the conversion factor that 1 ton of cooling is equivalent to 12,000 BTUs per hour. Therefore, 18,000 BTUs divided by 12,000 BTUs per ton equals 1.5 tons. So, 18,000 BTUs is equivalent to 1.5 tons of cooling capacity.
4800 BTUs will 150 square feet.
yes in a way. block heaters heat the coolant in the block there for warming the block up. coolant heaters heat the coolant out side the engine like in the hoses and radiater. and when the coolant gets hot enough it opens the thermosate and starts flowing through the engine..The coolant heater should be hooked into the engine so that it heats only the engine and the heater core. If the coolant heater is trying to heat the radiator then it will not work very well to heat the engine, you would need a lot of BTUs to heat the radiator as it will shed all that heat to the air that is surrounding it.
There are approximately 6,700-8,300 BTUs per pound of lignite coal. A ton of lignite coal contains 20-24 million BTUs.
