Pros and Cons of a Tankless Water Heater

Your water heater is the second biggest electricity user in the home, using roughly 18%. So when it's time to start looking for a replacement, you want an appliance that will save you money.

Have you ever considered a tankless water heater? Although they typically have a higher up front cost, they take up less space and are energy efficient. Here are the pros and cons you need to know before making the switch.


Energy-Saving Tankless water heaters use 30-50% less energy than the traditional water tank because they only heat the water when needed, avoiding stand-by heat-loss.

Space-Saving Since they don't store water, they are smaller, more compact and can be mounted to the wall.

Consistent Temperatures They provide a continuous supply of hot water, without running out.

Longer Lifespan Traditional tanks have a life span of 10-15 years while tankless units can last more than 20 years with the proper annual maintenance.


Higher Initial Cost The biggest disadvantage of a tankless water heater is the initial cost due to a required, dedicated sealed vent system.

Not Good for Larger Homes Although tankless units produce a constant flow of hot water, they cannot produce enough for multiple uses. For example, you cannot shower while running the dishwasher at the same time unless you buy a larger or multiple units, which can get pricey. .

Despite the cons that are associated with tankless water heaters, there are many pros that make them a great choice. If you have any questions or need to schedule your annual maintenance, call 72 Degrees Comfort Company at 515-965-7272 or email us at
