**How do you calculate heat load per person?**

A more accurate heat load calculation for any type of room or building

- Calculate the area in square feet of the space to be cooled, and multiply by 31.25.
- Calculate the heat gain through the windows.
- Calculate the heat generated by occupants, allow 600 BTU per person.

### How do you calculate BTU for a room?

Step 1: Measure The Square Footage (Length, Width, Height Exact To 0.25 Ft)

- Square Footage = Measured Length x Measured Width.
- Square Footage = 16 3/4 ft (Length) x 14 1/2 ft (Width) = 243 sq ft.
- BTU Requirement = 500 sq ft x 20 BTU per sq ft = 10,000 BTU.
- Accurate BTU Calculation = 20,000 BTU * 1.1 + 600 BTU = 22,600 BTU.

**How many BTUs Does a person produce at rest?**

If you are sat at home, relaxing in your living room, watching telly, slobbing out, the most amount of heat that your body is going to produce is about 356 BTUs/hour.

## How many BTU do I need for 140 square feet?

The BTU needed to cool down a room of known footage that can be calculated. According to The U.S. Department Of Energy recommendation for the size of room air conditioners: “…an air conditioner generally needs 20 BTU for each square foot of living space.”

**How many BTU do I need calculator?**

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.

### What size room can a 12000 BTU air conditioner cool?

600 sq ft.

Answer: Using the EPA’s 20 BTU per sq ft rule of thumb, the room size of 12,000 BTU air conditioners is 600 sq ft.

**Can a human body heat a room?**

Idly mingling, a human body radiates about 100 watts of excess heat, which can add up fast in confined spaces. Heat also loomed from the friction of trains on the tracks, and seeped from the deep maze of tunnels, raising the platform temperature to around 70 degrees, almost a geothermal spa.

## What is the highest BTU?

– The heater is portable because of the wheels and the handle – The safety guards on the intake and outlet end to protect the internal components – Wide temperature range of from 40 degrees Fahrenheit to 100 degrees Fahrenheit

**What Wood has highest BTU rating?**

– For firewood, use dry hardwood such as oak, cherry, hickory, maple. – To get a fire going use just enough softwood for kindling. – Don’t burn plastics or paper with color printing, such as junk mail, flyers, comics, magazines, gift wrap, etc. – Absolutely NEVER use flammable liquids in your fireplace or wood burning stove.

### How do you measure BTU?

– For a rectangular room, multiply the length and width, measured in feet. – For a triangular room, multiply the length and width, then divide by 2. – For a circular room, measure the radius (“r” which is the distance from the center to the edge). – For rooms with odd shapes, divide them into regular shapes and measure each shape separately.

**What type of coal has the lowest BTU rating?**

Subbituminous coal has low-to-moderate heating values and is mainly used in electricity generation. Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat.
