Tankless water heater vs. Storage tank water heater
A Tankless water heater heats the water only when there is a demand for hot water. Opening a hot water faucet, ignites the powerful burners and the computer monitors the water temperature and adjusts the burners according to the need. High demand, high heat. Low demand, low heat. With no tank to run out you get an endless supply of hot water. No tank to heat means no standby heat loss.
A storage tank water heater stores 40-75 gallons of hot 140*F water 24 hours a day, 7 days a week though you only use hot water a couple times a day. The tank type heaters constantly lose heat through the flue and tank walls trying to maintain 140*F. The heater cycles on and off to maintain this temperature. This causes cracking of the exterior walls and sediment build up which will eventually cause your storage tank to leak. The storage tank is designed to wear out and be replaced in time. The storage tank water heaters only have a limited amount of hot water and after that water is used you have to wait for the tank to heat the water again.
