|800 sq ft home||36,000 BTU furnace|
|900 sq ft home||40,500 BTU furnace|
How many BTUs do I need for a 900 square foot house?
A 100- to 200 square-foot room, such as a small home office, will have an average recommendation of 4,000 to 8,000 BTUs. For a space of 800 to 900 square feet, such as a small home or two-bedroom townhouse, the recommendation is between 30,000 and 45,000 BTUs.
How many BTUs do I need to heat my house?
For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x . 133 = BTUs needed per hour.
How many BTU do I need to heat a 12×12 room?
If you want to properly cool down a 300 square foot area (or room), you need a 6,000 BTU air conditioner. Obviously, the problem arises when you have a tiny 12×12 room, for example. According to the US Department of Energy directive, an air conditioner’s most appropriate size would be 2,880 BTU unit.
How many square feet will a 30000 BTU propane heater heat?
How Many Square Feet Will 1,000 – 30,000 BTU Heat?
|Heating Output:||Square Footage (Standard Climate)||Square Footage (Very Hot Climate)|
|15,000 BTU||333,3 sq ft||500 sq ft|
|20,000 BTU||444,4 sq ft||666,6 sq ft|
|25,000 BTU||555,5 sq ft||833,3 sq ft|
|30,000 BTU||666,6 sq ft||1000 sq ft|
Is it better to undersize or oversize a furnace?
An undersized furnace will work fine for the majority of the time, but every once in a while it won’t get the house quite as warm as desired. An over-sized furnace will keep the house warm no matter how cold it gets outside, but it does so at a cost. First, it will probably make the house less comfortable.
How many square feet will an 80000 BTU furnace heat?
How Many Square Feet Will 30,000 – 120,000 BTU Furnace Heat?
|Furnace Capacity||Square Footage(Hot Climate)||Square Footage(Cold Climate)|
|70,000 BTU||2,320 sq ft||1,270 sq ft|
|80,000 BTU||2,650 sq ft||1,450 sq ft|
|90,000 BTU||3,000 sq ft||1,630 sq ft|
|100,000 BTU||3,320 sq ft||1,810 sq ft|
How do I calculate BTU for my house?
How many BTUs do I need for a 1000 square foot house?
Area = 40,000 BTU / 40 BTU per sq ft = 1,000 sq ft In a standard climate, 40,000 BTU is enough to heat a 1,000 sq ft area. Obviously, if you live in colder climate, a 40,000 BTU heater will heat an area below 1,000 sq ft.
How many square feet will 65000 Btu heat?
How many btu do I need to heat 3,000 square feet?
|Room/Area Size||Heating Capacity(BTU)|
|1,000 sq ft||45,000-55,000 BTU|
|1,200 sq ft||55,000-65,000 BTU|
|1,300 sq ft||59,000-71,000 BTU|
|1,400 sq ft||63,000-77,000 BTU|
How many BTUs do I need to heat 1000 square feet?
In more moderate climates, multiply by 20 – 30. And in cold climates multiply the square foot number by 30 – 40. For example, if you’re trying to heat 1000 square feet in a cold climate, 30,000 – 40,000 BTU’s will add significant warm air to your home.
How much BTU do I need to heat Miami?
Example: Miami, Florida, is in Climate Zone 2 and requires 35 BTU of heat per sq ft. Chicago, Illinois, is in Climate Zone 5 and requires 50 BTU of heat per sq ft. To help you figure out which climate zone you should input into the heating BTU calculator, you can use this map by Office of Energy Efficiency & Renewable Energy:
What size heater do I need to heat a house?
As you can see, in the north, you need about double the heating output to heat 1 square foot compared to the extreme south. Example: With 35,000 BTU, you can heat a 1,000 sq ft home in Florida. If you’re from Chicago, a 35,000 BTU heater will adequately heat a 600 sq ft home.
How many BTUs do I need for my energy needs?
Climate also plays a role in determining your energy needs. Warmer climates along the southern part of the United States – considered Zone 1 or 2 – require 30-40 BTU per square foot. The middle part of the country – Zone 3 and 4 – require between 40-45 BTU per square foot, while the northern areas of Zone 5 need up to 60 BTUs per square foot.
