Natural Gas is again increasing in popularity and fast becoming the preferred method of heating for hot water systems in many Australian homes

Mott Plumbers Adelaide

Gas hot water units are generally cheaper to run than electric units and are better for the environment.

There are several benefits of using a gas storage or gas continuous flow hot water system over the traditional electric hot water system. Gas provides a more environmentally friendly option and is generally quicker to heat the water. Unfortunately, natural gas isn’t available in all areas but LPG provides an alternative. While LPG can be accessed in a bottled source, running costs can be quite high.
