You may first think about using a conventional storage-tank water heater or a tankless heater when it's time to replace an old water heater or install a new one in new construction. Each option has benefits and drawbacks, just like any significant equipment purchase.

Read on to learn more about the difference between using tank storage or a tankless water heater to help you decide.

Tankless Water Heater

While a storage tank system continuously heats water in a storage tank, a tankless design heats water as it flows through the appliance.

Pros

1. Energy Efficient

Tankless water heaters heat water only when needed, therefore eliminating standby loss of 24%–34% energy for homes that utilize 41 gallons or less. When you turn on the hot water tap, cold water enters the unit through a pipe and is heated by an electric or gas burner. No hot water is wasted, saving families energy and money.

2. Saves Space

Traditional tank-style water heaters take up more space than tankless water heaters. The heaters are small and can be mounted on the wall. 

3. Continuous Hot Water

Tankless water heaters offer a continuous supply of hot water that is heated to a predetermined temperature, which is perfect for filling a big tub or whirlpool. With this, you would have more than enough hot water to take several showers.

Cons

1. Higher Installation Cost

Going tankless typically costs twice as much as the traditional one. This is because it lasts longer than standard storage heaters, and the unit's initial cost is offset. Moreover, tankless water heaters frequently necessitate the installation of new gas lines and venting. This substantially increases installation costs.

2. Output Challenge

Multiple faucets must be operated simultaneously by tankless systems. For instance, changing the settings on a kitchen faucet while someone is in the shower frequently causes changes in the water's temperature and pressure. Installing a unit at the water outlets that are used the most frequently can solve this problem.

Tanks Storage Water Heaters

Most homeowners and renters use storage tank water heaters that can store 20–80-gallon of hot water. Electricity, gas, oil, or propane heats the reservoir to fill the tank producing hot water you need. 

Pros

1. Cheap Installation Cost

This is because the tank can be installed above ground, eliminating the need for costly excavation. In addition, the tank can be placed on an existing concrete pad, reducing the installation cost.

2. Inexpensive Repairs

Storage tank water heaters are less expensive to repair than tankless water heaters. This is because the tankless water heater has more parts that can break down and need to be replaced.

3. Output Advantage

Tank water heaters are also great at simultaneously supplying water to numerous faucets or appliances. This is perfect for bigger homes, but you'll need to pick a more extensive unit.

Cons

1. Energy Cost is Higher

Their utility costs can be very high due to their low energy efficiency. Your unit will continue to warm the water in the tank all day long, even if no one is home or using it.

2. Needs More Maintenance

Tank water heaters require more cleaning and maintenance. This occurs due to sediment buildup, tank damage, or rusting away. Because failure to do so can shorten the water heater's lifespan and effectiveness, you must regularly clean your water heater to remove sediment.

Conclusion

Understanding the distinctions between tankless water heaters, continuous flow water heaters, and storage water heaters is essential to choosing the best system for your needs. Discuss the two types of water heaters with your plumber to weigh your options.
