Heaters - How do they work?

Heaters can be broken down into two different types: water heaters and air heaters. Water heaters tend to come with or without a tank. The water heaters with a tank work very much in the same way as cylinders where the water is let in to the tank and then a series of immersion heaters are used to heat the water before it is pumped out. Tankless water heaters operate by heating the water on demand using a powerful heat exchanger. Using this method, they eliminate the “stand-by” heat loss that you get with a tank.

Air heaters have a variety of different types such as the air source heater and the convection heater. Air source heaters work by extracting the heat from the air outside, this heat is then used to heat water within systems of the house. Convection heaters use convection currents to spread heat around a room and are designed to optimise this process. The design allows air to flow up through the bottom of the heater to the filaments that heat the air. Once it is heated, the air is forced up as it is contained on all sides by the outer shell of the heater. As the hot air rises, more air is pulled in to the bottom by the convection current.
