Gas water heaters
It takes less energy to heat up water with gas than electricity, therefore in general gas water heaters are more energy efficient than electric water heaters, and as mentioned before have a lower annual operational cost. Gas water heaters heat water faster and have a faster recovery time than electric; this should be taken into consideration when assessing your household demand for hot water. In contrast to electric water heaters, gas water heaters work even if there is a power outage. A clear advantage that gas water heaters have over their electric counter parts is that they tend to not break down as easily as electric water heaters and in the case they do break down repair cost are cheaper.
