If you want to battle the heat, I’d add an extra 4,000 BTU to your cooling requirement. Kitchen. Trying to keep a kitchen cool while cooking is a monumental task.If the room is usually occupied by more than 2 people, we recommend adding around 600BTU per extra person. Not only from our bodies, but from the electronics we’re always using these days, too. People produce heat, and this definitely contributes to the heating/cooling you need. Outside Walls. Quite self explanatory here – if you’ve got exterior walls in the room, you’ll be dealing with more outside temperature input.

Large windows may need a power boost – especially if they’re drafty and not double glazed. Windows. Windows naturally let heat out/in more than a wall.Instead, add to your insulation! Insulation will always get you the biggest return on the dollar.

If you have bad insulation, don’t add anything to the power you need. Insulation is the #1 factor for heating/cooling efficiency. These next few points all relate to how quickly you lose heat. If it’s mostly in the shade, you can take 10% off instead, but do it conservatively. Make sure to keep your curtains closed to block any direct sunlight on a hot day. If you’re looking to cool a room that’s right in the sun, you’ll need another 10% boost to your BTU. If your ceilings are extra tall (above 8 feet), then add around 10% more BTU to your requirement. The taller a room, the more volume you need to cool. In short – hotter climates demand higher BTU ratings. So the hotter it is outside, the more power (in BTU) your unit needs to fight against that. An AC doesn’t just ‘get’ the coolness you want – it’s battling against the outdoor temperature. Your Climate. The thing to understand about air conditioners is that they operate relative to the outside temperature.Here are some major factors you should consider for the BTU you need for your space. But if mine is an uninsulated garage, and yours is an insulated living room, we’re going to need different levels of heating or cooling! This is a much easier rule of thumb than using BTU, with 3.41 BTU’s equal to 1 Watt.

ft room would simply need a 1500 Watt heater. In short, all we need to do is times the square foot of your space by 10. These are much simpler than in air conditioners and are more based on Watts than BTU. Likewise, space heaters also have standard measurements we can use. This table gives a quick overview of recommended air conditioning BTU’s by room size. Thankfully, everything is fairly standardized these days. There’s more ratings than the oscars: and it’s not easy to know how much you need. Getting the right amount of cooling power from an air conditioner is where you need to know BTU.

Use this to give yourself an idea, but you do really want a professional to run a detailed calculation before you buy a system costing thousands of dollars! Air Conditioning That being said, we can give some ball park estimates using typical sizes and calculators below. For example, too large of an air conditioner can lead to mold issues – because it cools too fast without being able to remove moisture from the air. Getting an approximate BTU requirement isn’t too hard, but you need to make sure you’re accurate. It’s important to know how many BTU’s you need to get the most efficient and comfortable heating/cooling system for your space. Your room may get way too hot or cold very quickly. With a unit related to power, this can sometimes be tricky for people to wrap their head around.Ī higher BTU means more heating or cooling power. So for a larger room, you need more power to cool or heat it.Īt the same time, too much power can be inefficient. These units are used mostly in manufacturing and home appliances. The bigger your room, the more BTU you need. This is the energy we need to heat (or cool) one pound of water by 1 degree Fahrenheit.īTU’s tells you how much heating or cooling an appliance can give you – and what size of room it can heat. Table showing various Quad measurements converted to british thermal units.You may be surprised to find out that 1 BTU isn’t the amount to heat 1 British cup of tea!īTU is a 200-year old acronym: BTU stands for British Thermal Units: a measurement of thermal energy. Quad to British Thermal Unit Conversion Table British thermal units can be abbreviated as BTU for example, 1 british thermal unit can be written as 1 BTU. The british thermal unit is a US customary unit of energy. They are often used as a way to rate the energy heat producing appliances such furnaces, and to price heating fuels such as natural gas. Specifically, one british thermal unit is equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. British thermal units are a measure of heat energy.
