Continuous flow hot water systems are small wall-mounted units that heat water as you use it, rather than heating it slowly and storing it in a tank, like storage hot water systems. So, if you plan on installing a new hot water system but you have limited space, then a continuous flow hot water system may be the best choice for you.
This article will discuss all you need to know about continuous flow hot water systems and their advantages and disadvantages. This should help you decide if a continuous flow hot water system is the right unit to use in your household.
How it works
Continuous flow hot water systems work by pushing cold water through copper piping and applying heat directly to these pipes. When a hot water tap is turned on, a flow sensor is triggered and starts the heating. In a continuous flow gas system, it triggers a burner. In an electric system, it triggers a heating element.
The water is heated to the necessary temperature, then fed straight through your tap. When the tap is turned off, the unit also stops working.
There are three types of continuous flow hot water systems in terms of energy source.
- Electric continuous flow hot water systems
- Gas continuous flow hot water systems
- Powered by natural gas, or
- Powered by liquefied petroleum gas
