What Is a BTU?
First, the term BTU stands for British thermal unit. It is a way to measure energy. A single BTU is the energy it takes to heat 1 pound of water by 1 degree Fahrenheit. One BTU is about the same amount of energy used from burning a single match.
Another way to understand a BTU is that it’s the standard system’s version of a calorie. Calories are a measure of energy in the metric system. When you count the number of calories you eat, you track how much energy you put into your body. When you count BTUs, you’re keeping track of how much energy your HVAC system can process to heat or cool a room.
BTUs and Your HVAC System
Regarding your HVAC system, the BTU tells how powerful your heater or air conditioner is. For instance, a furnace labeled at 5,000 BTU can produce 5,000 BTUs of energy over an hour. This is known as the BTU rating.
Therefore, a furnace with a higher BTU rating is more powerful. It has a higher heating output than one with a lower BTU rating. A higher rating can increase the temperature in a room each hour, so you can heat a room more quickly or heat a larger space.
HVAC appliances that use a BTU rating include:
- Heat pumps
- Water heaters
- Gas grills
- Air conditioners
How Many BTUs Do You Need for Your Home?
BTUs are a significant factor in choosing the right size heat pump, space heater, or cooling system for your home. How many BTUs you need to cool your room depends primarily on how much air you need to cool.
You first need to determine the square footage of your home or the area you’ll be heating. Once you know your room size in square feet, you can consult a BTU chart that breaks down the amount of heating power needed to keep that space comfortable.
Thomas Hoffmann Air Conditioning & Heating can help you determine the right system for your home and budget if you’re in the market for a new heater or air conditioner.
