Types and sizes of water heaters
Water heaters can be classified on different criteria, as gas or electric, tankles or storage tanks, residential or commercial, etc. The size and type of water heater you need is based on the size of your home, type of the heating system, whether the water heater is for a business or a home, etc. If you currently have a water heater installed, you can determine the size of your current water heater from the specification label, or the type of water heater by looking at the heater connections.

Energy Saver
The energy efficient water heaters may have a higher purchase price, but they will save you money during the life of the water heater. The Las Vegas Water Department provides from time-to-time rebates for newly installed Energy Saver water heaters.
