Large water heaters are unsightly appliances that home-sellers would rather hide. Although it's not always possible to banish these structures, it is possible to replace them with a version that is not as overbearing. Tankless water heaters have the potential to make one home stand out amongst the competition, but they do have some disadvantages along with the benefits.
Pro: Tankless Water Heaters Use Less Energy
Traditional water heaters continuously heat water that is just sitting in the tank, and this requires energy. Tankless water heaters, on the other hand, do not heat the water until someone needs it. Therefore, they are more energy-efficient and cost less to operate.
Pro: Tankless Water Heaters Last Longer
Traditional water heaters will need to be replaced after about a decade, but tankless water heaters can last much longer. If someone is planning on purchasing a home with a new tankless water heater, he or she would not have to think about replacing it for about 20 years.
Pro: Tankless Water Heaters Are More Space Efficient
The typical traditional water heater is 24 inches wide and 60 inches tall. Tankless heaters save a lot of space because they are generally only 20 inches wide and 28 inches tall. They open up a lot of space, and this impresses buyers greatly.
Con: There Is Less Available Hot Water with Tankless Heaters
Although a tankless heater can provide a home with hot water only when it is needed, the amount is limited to a few gallons at a time. This will mean that more than one occupant in the home cannot take a shower at the same time. They will definitely not be able to do this while they run the dishwasher or the washing machine.
Con: Tankless Water Heaters Are Typically More Expensive
Tankless water heaters cost around $1,000 while the traditional version only has a price tag equal to $300 or $400. While this higher up-front purchase cost is a con, if you consider that a tankless water heater should last longer than a traditional heater you may end up saving a bit over time.
