Here, after the current passes through a material, it generates magnetic materials. The following process is the Joule heating principle. Since the heat above equals the operating frequency, ordinary gate drive transformers do not work in high-frequency induction heating applications. So, the solid-state RF frequency power supply applies to the inductor coil and the materials you’ll heat. Because the loaded metal is iron, we’ll refer to the resistance R for the metal iron. The extreme heat is equal to the current 2x resistance of the iron. The principle also functions vice versa when the magnetic field changes in the conductor. Through the development of the high eddy current, the iron also heats up. Undoubtedly, it causes a reverse current which is the eddy current. ![]() During the induction heater circuit process, the frequency moves faster than the electrons in the iron. Working principle of Induction HeaterĪccording to Faraday’s law, learning the inductive heating process is essential-according to Faraday’s law of electromagnetic induction, switching the conductor in the electric field powers an alternating magnetic field. For large rooms, two small heaters will be quieter than one large heater.Source: 1. ![]() Open-coil elements make more noise than steel mass elements (Pic-A-Watt® ) due to the rate of heat exchange with the air. Noise: A propeller-type fan will make more noise than a squirrel cage fan. If budgetary constraints are of primary importance open-coil heaters are the least expensive. For supplemental or occasional use open-coil elements work fine. These elements carry a five year warranty and will hold up to the rigors of everyday use. Use: If the heater will run often and be used as primary heating for the home King recommends using heaters with steel elements such as the Pic-A-Watt®. As such, a baseboard set to 75☏ will cost you 15.5% more than a fan heater set to 70☏. Every 1° a thermostat is turned up will raise a power bill 3.1%. This process makes you feel cooler causing you to turn the baseboard thermostat to a higher temperature setting whereby it runs more often thus using more electric power than the same size fan heater. The difference is a fan heater gives more even heat throughout the room thereby reducing air stratification (hot air rising and not mixing with the cooler floor air). The small Pic-A-Watt® heater uses a squirrel cage blower which makes it almost inaudible.Įfficiency: A 1500 Watt baseboard uses the same amount of electrical power as a 1500 Watt fan heater. Noise: A baseboard heater has no moving parts and therefore is quieter than a fan heater. This reduces the severity of hot/cold temperature swings. A fan-forced heater will also maintain a more even temperature because the fan will circulate air around the room. (For example: a 2250 Watt Pic-A-Watt® heater will provide as much heat as a 9 foot baseboard.)Ĭomfort: A fan-forced heater will heat a room within a few minutes whereas a baseboard will require 30 to 40 minutes. Space: A baseboard heater takes up more wall space than a fan-forced heater which can cause problems placing furniture. A 120 Volt heater run at 240 Volt will be 4x 120 Volt rated wattage, destroying the heater which possesses a severe fire hazard. A 240 Volt heater run at 120 Volt will produce 25% of the rated wattage.
