Replace Water Heater With Tankless – Two days before Christmas we woke up to a pretty scary leak in our basement. We discovered an active drip in our water heater tank. Before the vision of the flooded basement crossed our minds on Christmas morning, we called our plumber. Even if you’re not really looking forward to replacing your water heater, this gave us a great opportunity to switch from a tankless water heater to a tankless water heater.
We considered replacing the water tank with a new one, but after a little research, we started to decide on a tankless boiler. We have found that the average lifespan of electric and gas boiler tanks is around 6 to 12 years. Most brands of residential water heaters have a 6 year warranty on the tank and parts, but in our experience our system broke within about 7 years. Of course he did. It’s almost as planned!

By comparison, several online sources (Plumbing Experts and Energy.gov) say the life expectancy of a tankless unit is about 20 years. 20 YEARS! And the warranty for a tankless unit is usually one year for labor and 5 years for parts, except for heat exchangers which are 12-15 years.
Maintenance Tips: Keeping A Tankless Water Heater Efficient
While we can’t tell you what’s right for your home, we want to walk you through our thinking and personal experiences that led us to switch from a water heater to a tankless water heater. Our situation is unique in that we were able to experience both a tankless water heater and a tankless water heater in the same home under the same conditions. It was nice to test both boilers and compare apples to apples.
We chose the Rheem Performance Platinum 9.5 GPM Gas High Efficiency Tankless Water Heater. It has over 800 4-star reviews at Home Depot, and our friends at Rheem recommended this unit for our 4,000 square foot, three-story home.
We had a 50 gallon water heater which was perfect for our small family of four. Normally we didn’t run out of hot water while showering, but we found that we had to constantly adjust the setting and raise the temperature while showering. I just assumed it was because our bodies were getting used to the temperature, but after the rain without tanks I now realize it was because we pushed the tank to the limit. The main disadvantage of the boiler is the limited amount of hot water, which is especially noticeable when we have roommates. It takes a little over an hour for the tank to warm up again.

With a tankless device, water is not stored in a huge tank. When the hot water tap is turned on instead, cold water flows into the unit and warms the heat exchanger, allowing you to provide hot water much more efficiently when needed.
We found that with the instantaneous water heater it took a few seconds longer for the water to reach the desired temperature, but after that it stayed there. I didn’t have to adjust the temperature at all during the entire shower! We also didn’t dare to turn on other faucets with our old water heater, turn on the dishwasher, or put laundry in while taking a shower, because the hot water in our shower would definitely be affected. Not so with a tankless unit. We can do laundry, wash dishes and turn on other faucets without sacrificing a hot shower!
In areas with hard water, scale can build up in the boiler’s heat exchanger, which can restrict water flow and reduce the performance of the water heater. It is recommended to flush the boiler regularly. Because of the hard water in our area, the plumber suggested flushing the tank annually. Rheem provides instructions on how to do this safely and effectively. However, if you are not comfortable with this procedure, contact a plumber.

The 50 gallon water heater that came with our house when we bought it cost about $1,200. Hot water tanks can use significantly less and usually cost around $400 depending on features. I don’t know why ours was so much more expensive, but it broke after seven years, so it’s safe to say it wasn’t money well spent. Looking for a tankless replacement, we decided to stay in the same price range. The water heater we chose cost $1,400, so the cost difference between our old water heater and the new water heater was comparable. Judging by the feedback, I really hope our new Rheem unit will last many years longer than our water heater!
When it comes to real estate resale value, a tankless water heater can often be a selling point. We talked to our agent and most buyers in our area are not aware of the difference between a tank and a tankless unit, but those who have experience with a tankless unit prefer them.
Another advantage of the tankless machine is the space-saving design. The small wall-mounted design frees up valuable floor space. It is much easier to look around, under and over the unit without a tank than with a huge tank. Our water boiler is located in our basement, where we also store seasonal goods. So I’m happy to take some of that space back because a tankless water heater has a smaller, more efficient footprint.

It took our plumbers about three hours to remove our old water heater and replace it with a tankless water heater. First, the main water tap and gas line were turned off, the tank was drained and the connections were disconnected. We had to add a horizontal block to the bolts so they could hang without the tank. They then reconnected the gas, water, and exhaust lines and replaced the copper tubing with PEX tubing. It seemed like a fairly easy transition from a tank to a tankless water heater.
Now that we’ve had a few months to try this boiler, we’re very pleased with it. We think this was a great improvement on our water heater. If our water heater had catastrophically failed, we would have flooded our basement with 50 gallons of water. I feel much more comfortable knowing that we won’t have to deal with 50 gallons of water if this tankless system fails. It heats the water as needed, so we don’t have to worry about running out of hot water. We can use multiple faucets at once without compromise, the temperature remains constant, and the smaller footprint is greatly appreciated in our already crowded basement.
