Brief summary different systems
Hot Water System feature variables Tankless hot water system features Storage tank hot water system features
Energy cost Lower cost ... reduced energy losses Higher losses ... higher energy usage
Unit size Much smaller than hot water storage tank Large compared to tankless hot water heater
Installation cost Small compared to storage tank heater in new structures but higher in retrofit More complex to install in new structures
Installation space Compact unit .. saves space taken up by storage tank hot water heater which can be used as closet for example Bulky heater and tank system with difficult access normally
Capacity When large quantities are required simultaneously flow can reduce or temperature of water is reduced Normally depending on size of tank capacity is higher for simultaneous use
