An electric heating coil can form an integral part of the heating in any home. It helps to keep you warm and comfortable all winter long and heats the water for your shower, as well as makes your morning espresso. But how does it work?
This blog post will provide a guide on how heating coils work. We will also discuss the different types of heating coils and how they can be used in your home. So, if you're curious about how coils work, this blog post is for you!
How Does A Heating Coil System Work?
Different Types of Heating Coils
Air heating coils do not require insulating from the air but do have to be supported on a mica or ceramic carrier to prevent the wire from coming into contact with the housing of the appliance. To improve the heat transfer they are often not simply coils of wire but are formed into more complex shapes like the ‘porcupine’ electric heating elements in tumble driers. Heating coils for liquids are usually placed within a stainless-steel tube on ceramic supports and the space around the coils is filled with a ceramic powder like magnesium oxide.
Electric Heating Coils Around the Home
You are likely to have a number of different heating coils around your house. In the kitchen, the oven, electric stove, kettle, washing machine and your coffee maker will have coils insulated in steel tubes. The tumble dryer will have a supported coil making heat with a fan blowing air across it in a classic forced air convection system and blower fires also use this type of coil. If you have a hot water tank, a steel insulated coil will be inserted to form the immersion heater element which complements the copper heating coil containing hot water from a heat pump or gas boiler.
