Natural gas water heaters generally create far fewer greenhouse gas emissions than electric powered hot water systems. This is because natural gas burns more efficiently than the coal burnt to generate the electricity, this is shown in the energy efficient star rating. Gas hot water can be sectioned into storage or instantaneous systems with either gas pilot light or electric ignition.
Electric ignition instantaneous systems are more economical because they only heat the water that is required however they need a high gas flow and may need the installation of larger gas pipes.
