If you haven’t heard by now, in an effort to improve efficiency, the National Appliance Energy Conservation Act (NAECA) will impact the design and efficiency of new water heaters. These new government mandated water regulations will start on April 16th, 2015. This means that all products manufactured after this date must meet the new regulations. You can read more about the act here.
The new regulations mean the physical units will be larger, thus presenting potential problems for water heaters currently operating in tight spaces. If you have an older water heater in a smaller space, it could be very beneficial to replace it before the new regulations go into effect.
