Gas water heaters are essential tools for most homes. It stores hot water for space heating as well as domestic use.
This type of heater either uses natural gas delivered through a piped gas network (also called reticulated gas) or liquefied petroleum gas (LPG).
Gas water heaters are less greenhouse-intensive than their conventional electric counterparts. Through lowering greenhouse emissions, homeowners are able to play a role in saving the environment.
In the case of instantaneous hot water systems, users are able to have access to unlimited hot water which proves to be convenient.
Another benefit of using gas water heaters is its lower upfront costs as compared with solar or heat pump systems.
Some homes, however, are not suited for this kind of water heating system since it requires access to piped or bottled gas.
Moreover, when a household uses instantaneous systems, there may be an increase in their water use because water has to pass through the unit in order to ignite the burner.
Finally, unlimited hot water supply may result in an increase in energy costs.
