Learning how to calculate tonnage for HVAC systems is important if you plan on purchasing one of the more common systems. Knowing how to calculate is what will determine the number of cubic feet of gas, oil and other air that a system requires in order to operate properly.
There are many different types of heating systems, including central, radiant, infrared, tankless, propane and other options. Each uses different kinds of fuel, so there is a tonnage requirement. In general, the less fuel the system uses, the less it needs.
One of the first things to consider when thinking about how to calculate tonnage for a furnace unit is the amount of BTU’s used by the system. You can easily do this by adding up the current wattage of the system and dividing by the BTU’s available in the system. This is the same number that the manufacturer will give you when you purchase your unit. The formula is very easy, and a professional mechanic should be able to do it quickly.
Another thing to consider when learning how to calculate tonnage for HVAC systems is the size of the system. What will need to be added to the equation is the total size of the room, including any partitions, doors or window treatments. If you have windows and doors of different sizes, you will also need to add the numbers to the equation. Adding the sizes of windows and doors together is not difficult, but you must remember that the larger the window or door is, the more overall surface area you will need to cover with a space heater.
The tank is a critical component of a system and should not be ignored when figuring out how to calculate tonnage for HVAC. Tank capacities vary depending on the model, so a professional mechanic should be able to help you figure out your tank size. The tanks themselves come in all different sizes, so you may want to get a few different tanks to ensure that they fit perfectly. When buying tanks, make sure that they match or exceed the amount of heat that you need.
When measuring the actual size of the furnace, be careful not to mix up gas cylinders and other components. Gas cylinders do not have a specific size, but they are usually sized by the volume of the gas. When determining how to calculate tonnage for HVAC, be sure to use the amount of gas in the system, not the actual gas volume.
Electric space heaters are another popular type of space heater and many people choose to install one for their heating needs. They come in a variety of models, and you can easily learn how to calculate tonnage for your electric heater. The same rule applies to these units, so measure the heat needed by subtracting the wattage of the electric heater from the overall wattage of the entire system. This way, you will have a perfect fit for your heating system.
Learning how to calculate tonnage for HVAC is essential, and it is best learned before you purchase a unit. With a few simple calculations, you will be able to determine the size of your heating system, and the amount of air and fuel that you will need to ensure proper operation.
