About Tankless Hot Water Heaters

Let’s talk about the tankless water heater and why it could potentially be the right choice for you. Tankless water heaters work a little differently than traditional water heaters. They focus on continuous hot water rather than large volumes of hot water at a time.

This is based on how they in a much smaller space heat the water.

As you can see with the space being smaller it limits how much water can be heated at one time. Generally, a tankless water heater puts out about 5 gallons per minute of hot water with some putting out up to 12 gallons per minute. With a regular shower using 7-10 gallons per minute and a water saving one using 2-4 gallons per minute it gives you a basic idea of what you may be looking at with a tankless water heater. Of course, most people also don’t use straight hot water for their showers, but other appliances such as a dishwasher or washer at times do. These are all things to take into consideration when looking at a tankless water heater.

Generally, a tankless can save you money over time if you are converting from an older electric water heater, but that savings can be nominal when looking at the more efficient well insulated gas tank-type heaters.

The lasting hot water is the real selling point with this item. There is no reheat time. And if you are filling one of the modern soaking tubs (which generally hold several more gallons that a typical hot water heater) or have more than one person cycling thru showers in the morning or evening a tankless can be your best bet.

Another selling point is the space saving you get out of this item, and who isn’t looking for more closet or other space in your home regardless of size?

The last potentially most important advantage of the tankless is that it simply lasts longer – as much as 3X longer than a tank heater. Regardless of tank or tankless heater when it goes out it will take a chunk of money to replace, the tankless a little more if you are converting from a tank system. But overall if the tankless is maintained thru a maintenance program it should last well past 20 years whereas if you have a tank system you are looking at putting out that install money more times in that time frame as the generally last about 8-10 years even maintained.

Basically, with the potential amount of money saved over a period of time due to longevity and a little lower heating cost if your usage warrants it a tankless water heater could definitely be worth the initially higher investment costs to get it installed.
