Remember the equation watts = volts*amps. You pay your electricity bill by the amount of kilowatts (1 kilowatt is 1,000 watts) that you use per hour. The measuring stick which defines cost to run an infrared heater is wattage (power). When it comes to infrared heaters, what is the most efficient combination to use? In our example, hose #1 with 3 gallons of water flowing out has the same wattage as hose #2 with double the pressure and half the flow rate (1.5 gallons). The equation for wattage is voltage times amperage (Watts=Volts*Amps). With hose #2, the flow rate (amperage) is decreased to half of its original flow rate, it’s a narrower but more intense stream of water. However, the water no longer gushes out of the hose, it’s in a concentrated stream. Doubling the pressure on hose #2 is equivalent to doubling the voltage. You can create a stream of water that shoots across the lawn. Imagine that you put your thumb over hose #2 and apply double the pressure. The water might pour up to a few feet out from the hose as it gushes out.
From example 1, imagine those 3 gallons of water flowing out of hose #1 with no nozzle. For example, let’s say you have two hoses next to each other, each with a flow rate of 3 gallons per minute. Amperage is the flow rate of the water through the hose.To understand how electricity work think of it as if it were water flowing through a garden hose. Heating Green is here to explain the difference between watts, volts, and amps.Īll electric appliances have 3 specifications: wattage, amperage, and voltage.
