4 Advantages And Disadvantages Of Installing A Tankless Water Heater In Your Home

Posted on

Like many homes, yours may use a traditional water heater to heat and store hot water for showers, laundry, dishes, etc. However, more and more people are ditching their old water heater tanks for tankless systems because of their many benefits. However, while tankless water heaters have any advantages, they also have a few drawbacks to consider first, so check out these four pros and cons of installing a tankless system in your home.

Pros: They Use Less Energy Than Traditional Water Heaters

A traditional water heater uses a tank to store a certain amount of water. When you use the hot water somewhere in your home, it is pulled from this tank. Unfortunately, to keep the water in the tank hot and ready to go at a moment's notice, it needs to use energy constantly. Newer models have better insulating properties, allowing the water to stay hot with less energy, but they all suck power to keep a constant supply of hot water.

A tankless system doesn't have a reserve of hot water. Instead, when you turn on the hot water, the tankless system's heater begins heating the water as it flows until the flowing water is the right temperature. Therefore, the system is only using power when you need hot water, which can save you money each month.

Pro: They Require Little Maintenance or Space

While having a tank full of hot water is nice, it also takes a lot of space. In smaller homes, having a plumbing replacement company install a tankless system means you have more floor space. If you choose a whole-home tankless water heater system, you'll have one unit, which easily fits in a small closet. You can also choose a point-of-use tankless system, which only heats one faucet.

Tankless systems also require less maintenance than a tanked system. This is largely due to the buildup that collects in tanked systems. Sediment and other residue can gather on the inside of the water heater. This can affect how well it works, but it can also prevent it from filling fully. In most cases, it's recommended you have your water heater flushed out about once a year. With a tankless system, however, there's nothing to clean.

Con: They Are More Expensive Than Water Heater Tanks

You will save money if you choose to stick with a traditional tanked system. On average, you'll pay about $300 to $3,500 for a traditional tank water heater, but a tankless system may cost you up to $5,000. Eventually, you'll recoup this money in monthly savings, especially if you use a lot of hot water, but for many homeowners, a tankless system is simply too expensive.

On the other hand, you save money in the long run with a tankless system. Of course, you save money with lower energy bills, but you also won't need to replace a tankless system as often because they last about 20 years. A traditional water heater may last only seven years. Therefore, with a traditional system, you may spend more overall.

Con: They Take Time to Generate Hot Water

The appeal of traditional water heaters is the tank. The hot water in the tank starts pouring the moment you turn on the hot water, so you don't have to wait for the water to get hot. However, with a tankless system, the water doesn't start getting hot until you turn on the hot water. Therefore, you may have to wait a bit before the water from the faucet turns hot.

There is an advantage to this process, however. Besides saving you money, it ensures you never run out of hot water. Water heaters store a lot of water, but if someone takes an extremely long shower, multiple people shower in a row, etc. the tank can get empty. When this happens, there is no hot water until the tank is refilled and the water heated again. With a tankless system, you only run out of hot water if the energy supply is lost.

If your water heater is getting old, instead of replacing it with another tanked system, consider a tankless water heater. They have many amazing features, but they are initially expensive to purchase. For more information regarding water heaters, contact a commercial plumbing service in your area today.
