  • Big and Bulky: A majority of the conventional water heaters take up precious space in a laundry room or mechanical room.
  • May be Inadequate: Conventional water heaters, depending on the hot water needs of the household, may not be able to meet the demand.  If the water heater is sized incorrectly hot water will run out during peak demand times.  Also, only about 70% of the hot water in a conventional water heater is available for use.
  • Less Durable: When a conventional water heater reaches its life expectancy after 8 to 12 years they can begin to leak and cause property damage.
