Calculate the wattage of the device by multiplying volts and amps together. For instance, a 120 V space heater that requires 15 A would have 1800 W (120 * 15). Find the total number of watts required for heating purposes from manuals provided by manufacturers or online sources.
What is a low wattage radiant heat unit?
Low wattage radiant units – these heat objects (not the air like low wattage convectional units) are then radiated. They’re often more efficient than other types of space heating options, but they still do need to be plugged into a power source for them to work correctly.
What happens if a convection unit uses an electric resistance element behind its fan?
High wattage convectional units – if your unit uses an electric resistance element behind its fan, it will require electricity even when not operated! These have higher energy consumption rates, so you’ll want to ensure that you don’t overload any circuits in your home or create issues with your breaker box by plugging too many high-watt devices on one circuit.
What is the NEC for a space heater?
The National Electrical Code (NEC) is a must-follow guide for sizing circuit breakers. To sum up the NEC, every space heater must be connected to its 20-amp breaker or fuse in your electrical panel. If you are using multiple heaters on one outlet, then know that it needs to have its 40-amp breaker/fuse as well.
Why do heaters use more power than straight coils?
In addition, heaters with heating elements made of coiled wire (i.e., flat coil) draw about 15% more power than those with straight element coils because it takes less time to heat up, resulting in faster temperature rise times.
