Energy Efficiency – A tankless water heater if often more efficient than its tanked counterparts. The U.S. Department of Energy estimates that most of these systems use between one-fourth and one-third less energy than standard water heaters in homes that use 41 gallons of hot water daily. On average, most families will save $100 in energy over a year with a tankless water heater. This makes them a popular choice for households looking to cut down on monthly gas or electric costs, or those looking to curb their impact on the environment.
Endless Hot Water Supply – This is the most touted feature of tankless water heaters. Since the heater warms water as it travels through pipes in the tankless system, it can virtually provide hot water, on-demand, to the faucets of your home. This makes tankless systems highly popular with large households or multi-generation homes, where hot water has a peak demand in the morning as everyone takes their showers.
Lasts up to 20 years – In contrast to standard water heaters, which typically last between 10-15 years, tankless water heaters can last 15-20 years, and sometimes even longer with some upkeep and maintenance from a professional. This means that you could end up purchasing two conventional water heaters in the time that a tankless system would still be working fine. That makes the higher upfront cost more even, over the long run.
No risk of flooding – Many homeowners live in fear of their standard hot water “bursting”—without an emergency water shutoff, such an accident could severely damage your home. However, since they don’t have a tank, tankless water heaters do not carry this risk of bursting and flooding your home. You may find that this peace of mind is the one non-negotiable item on this list: after all, it’s hard to put a price on being able to relax on vacation without worrying about your water heater.
