Top 3 Most Common Types of Hot Water Systems for Domestic Homes
When it comes to hot water systems, there are many options available. However, for most domestic homes, three types of hot water systems are commonly used. These include:
Gas Storage
Gas storage hot water systems are the most frequently used type in standard homes. These units work by pumping cold water into a tank, which is then heated by a gas burner. Once the water reaches a specific temperature, the system automatically maintains that temperature throughout the day. Gas storage units come in various sizes and two different versions: indoor and outdoor. The indoor type requires a flue for ventilation. The downside is that the storage unit can run out of hot water if it is used constantly.
Electric Storage
Electric storage hot water systems are an alternative to gas units, commonly used where gas is not available. These systems work by using heating elements, and they come in different sizes and capacities. Unlike gas systems, electric storage units are safe to install indoors since they don't emit CO2 and do not require any ventilation. Similar to gas storage units, electric storage units can run out of hot water if used constantly.
Continuous Flow
Continuous flow, also known as "instantaneous," is a smaller type of hot water system that doesn't store water. Instead, it heats up the water used in the moment. Continuous flow units come in different sizes depending on the hot water requirements or the number of bathrooms in the house. There are indoor and outdoor versions of continuous flow units. However, the indoor version requires ventilation and a flue to the outside. It's important to note that switching from a storage unit to a continuous flow unit may require upgrading the gas line size since continuous flow units require a larger amount of gas to heat water instantaneously.
Always ensure to use a licensed plumber for installation and maintenance of your hot water system.
