Electric Water Heaters
Electric water heaters are very similar to their gas counterparts. The main difference between the two is the fuel source. Electric water heaters need no venting and require no flue for exhaust gases.
The heating elements on electric units are small. As a result electric water heaters may take a slightly longer time to recover when used. Read about saving electricity here. Read about gas water heaters in the Plumbing section here.
Review and follow the manufacturer’s instructions and maintenance timetable for your electric water heater.
