Tankless water heaters have become one of the most popular new appliances for newly constructed and replacement water heating systems. The choice of which type of water heater a home owner should invest in, whether tankless or a tank water heater should be best on the needs of the residents of a building a building design. In some cases, depsite not being as energy efficient the water needs of a large group of people may lead to the decision to use a tank water heater.
For a large family in a house it can be possible for a tank water heater to be more efficient because the large water needs could be too much for a tankless water heater to handle. On average, a tankless water heater produces around 5 gallons of hot water at 90 F per minute; this is not always enough water to feed washing machines, dishwashers and showers running at the same time. In large houses it is often best to use a combination of tankless, or on demand water heaters and a single tank water heater; for a single faucet or bathroom a long way from the tank water heater an on demand heater can stop people needing to run water for a long period of time as they wait for hot water to reach the faucet.
A tankless water heater generally has a longer lifespan than a tank version; on average a tank heater has around a 13 year lifespan and a tankless around 20 years. In general, this different lifespan is the cause of the tank water heater storing water inside and corroding through the water sitting inside. A tankless water heater does not store water inside and therefore does not corrode to the same extent.
Tankless water heaters are generally more expensive than their tank counterparts in upfront costs; however over the course of its life a tankless water heater saves between 10 and 20 percent in energy and water bills. The amount of wasted water that sits unused in the tank water heater is not a problem in the tankless models as they do not store water.
