Time to replace a hot water heater? Trying to decide whether to spend a bit more money up front and purchase a more efficient tankless model? There are many reasons to choose a tankless water heater over a standard, old fashioned, tank water heater. Often called and on-demand or even an instantaneous water heats, a tankless water heater can reduce energy costs by 30 to 50%. A traditional water heater works by heating and maintaining heated a large quantity of water, 30 to 50 gallons, which is stored in a large metal tank that is insulated. These tanks can be of varying sizes depending on the hot water usage of the homeowners. This water is maintained hot throughout the day and night, even when the family is out of the home, or on vacation.
Conversely, a tankless water heater only turns on when water begins to flow through the unit, or only in the exact moment that hot water is needed in the home. A typical tankless water heater can provide 2 to 5 gallons or roughly 7 to 15 liters of water per minute, every minute, without a recovery period. Compare it to leaving a car running, waiting for someone to drive it, 24 hours a day, or just starting the car when ready to drive. Imagine the difference spent over one year in gasoline? Although, the initial cost of installing a tankless water heater can be higher than a traditional tank-style water heater, the average home-owner can expect to recuperate those costs in energy savings within the first 3 to 5 years. Additionally, tankless models are known to last, with a life expectancy of up to 20 years, where a tank-style model may need to be replaced within 10 to 15 years.
So, considering all of the above mentioned factors, just how much more expensive is the intial cost of a tankless water heater over a traditional tank model? A mid-range tankless model typically costs $2500 to purchase and around $4000.00 installed, often needing gas line rerouting and more complicated installation, whereas, replacing a tank model can cost as little as $1000.00. But, again, the tankless model can last twice as long as a regular tank water heater model, plus, saves on electricity.
