How To Figure Out Btu Needed

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 do you calculate BTU for a room?

For each room, multiply the BTU per square footage times the square footage of the room. For example, a home located in Zone 5 with poor insulation would require 60 BTUs per square foot. Therefore, a room that is 300 square feet will need 18,000 BTUs (60 x 300).

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 BTU do I need per square foot?

To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.

How do I calculate what size air conditioner I need?

To calculate the size of the air conditioner you need for a room, first, multiply the length of the room with its width. Then multiply it with 25 BTU to get the ample cooling for the room under different weather conditions. For example, if the room is 15 feet long and 12 feet wide, it comes to 180 square feet.

Is 8000 BTU enough for a bedroom?

Recommended BTU By Room Size If you are looking for an air conditioner for a room measuring say 10′ x 15′ (150 square feet), the recommended BTU range is up to 5400. Once you get into 340 and 400 square feet per room, you’d need an 8,000 or 9,000 BTU air conditioner, respectively.

How do you calculate BTU per hour?

BTU/hr is measure of the thermal or heat energy generated per hour and is a measured to used specify air conditioners. The formula for calculating BTU/hr is: Heat Dissipation (Watts) x 3.4192 = BTU/Hr. So if a server has a heat dissipation (output) of 500 Watts the thermal or heat energy generated is 1709.6 BTU/hr.

What size room will 5000 BTU cool?

The size of your space determines how much cooling capacity you need. Budget air conditioners range from 5,000 BTU, which can handle about 150 square feet, to 12,000 BTU, enough to cover about 550 square feet. Naturally, air conditioners with higher capacities have higher price tags.

How many sq ft does a 15000 BTU AC cool?

Those in the 12,000- to 15,000-Btu range cost from $450 to $600, while large units go up to $1,200. Air conditioners rated at 15,000 Btu should be enough to cool most rooms up to about 875 sq. ft.

How many BTU do I need for a 20×20 room?

Rule of thumb. A 1 ton (12,000 BTUH) unit is doable in the space you want to cool. To handle the hot, humid summer heat of your area, I would increase it to 15,000 – 16,000 BTUH.

How many BTUs do I need for a 1200 square foot house?

A 1,200-square-foot home will require between 35,000 and 75,000 BTUs. A 1,500-square-foot home will require between 45,000 to 90,000 BTUs.

How many BTU do I need for 3500 square feet?

157,500 BTU Home Size (Heating): Standard Climate Very Hot Climate 3,500 square feet 157,500 BTU 105,000 BTU 4,000 square feet 180,000 BTU 120,000 BTU 4,500 square feet 202,500 BTU 135,000 BTU 5,000 square feet 225,000 BTU 150,000 BTU.

What size AC do I need for 1200 sq ft?

STEP 1: Determine how many BTUs of heating and tons of AC you need House Square Footage BTUs Needed 500 – 700 14,000 700 – 1,000 18,000 1,000 – 1,200 21,000 1,200 – 1,400 23,000.

What size room will a 12000 BTU air conditioner cool?

A 12000 Btu unit will effectively cool a room with a floor space of 500 to 600 square feet.

How many BTUs is 1hp aircon?

When choosing an air conditioner, usually a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity. The higher the listed BTU/hr, the greater the cooling capacity.

What size AC unit do I need for a 1300 sq ft house?

When looking for the quick answer to how much air-conditioning power you’ll need to adequately cool a 1,300-square-foot space, the answer is 23,000 BTUs per hour of air conditioning power. This is the base capacity needed for a 1,200- to 1,400-square-foot house.

Is higher or lower BTU better?

A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space.

Does higher BTU mean more electricity?

The more BTU your unit produces, the more energy it consumes. So, if you are worried about high energy costs, you should get a unit that is appropriate for your space.
