Big changes are coming to the water heater industry early in 2015. As a matter of fact, water heater efficiency industry standards will change with the manufacturing of tank type water heaters starting April 16, 2015. Manufacturers are required to increase the efficiency of all tank type electric water heaters by law. Your typical 30 or 40 gallon electric water heater will be larger in size for the same gallon capacity as before.
The water heater efficiency in energy will increase from 90% – 94% up to 96% efficient.
See the video below on how this increase in insulation will affect the size of your water heater. It will not make a big difference for garage kept water heaters but will affect the many multifamily dwellings with limited closet and storage spaces. Rest assured that 4 Star Plumbing Services is working hard to follow all of the manufacturers and keeping up with all of the water heating options available.
