Tank VS Tankless Water Heaters Guide by Expert

Water heaters are used for heating water in residential and commercial settings. This is an appliance that is found in every home and business that requires hot water. The major differences in water heaters can be found by examining tankless water heaters and tank water heaters. This is going to be largely based upon the consumption of energy needed to heat water.

Another consideration will be the variance that is noticeable even between water heaters using the same type of fuel. What are the differences when comparing these two types of water heaters? The tank water heater or storage water heater as they are sometimes called has a holding tank that cold water is sent to through a pipe. The water is heated once it reaches the tank to the desired temperature that has been set on the water tank.Tank vs Tankless Water Heater

A Look at the Tank VS Tankless Water Heaters

The water is stored in the tank after being heated until it is needed. This tank is an insulated unit that allows the water to be maintained at a certain temperature. However, if the water is not used within a short period of time after being heated, some temperature loss will occur, necessitating in the re-heating of the water to maintain the temperature that has been set.

Tankless water heaters do not have a tank, thus the name. The water is heated as it passes over the heating coils that are a part of the unit. This supplies the hot water as it is needed rather than keeping it heated constantly. For this reason, a tankless water heater is often called an on demand water heater. The energy efficiency of a tankless water heater is much better than a tank water heater due to this reason as well.

For example, when comparing the energy efficiency of the tankless water heaters versus the tank type, one comparison is the Rinnai line of water heaters. This may include the V53i model that is among the tankless water heaters made by Rinnai which allows users to reduce water heating bills by up to 60% over conventional water heaters. This water heater has up to 97% thermal efficiency.Tank or Tankless Water Heater

Benefits Realized by using Tankless Water Heaters

In addition to the energy savings realized by using tankless water heaters, there are a few aspects that are more beneficial.

  • The water heaters typically last longer than conventional tank type water heaters. A tankless water heater will last about twenty years and some even longer. Conventional water heaters have a life of about 8 to 10 years.
  • They do not store hot water. This reduces the build-up of lime and sediment that occurs in conventional water heaters.
  • Tankless water heaters are compact. They can be attached to a wall, which leaves more space for other needs. No storage tank means more room and they will fit in a variety of places.
  • Tankless water heaters do not heat water until you need it. Conventional water heaters constantly heat and re-heat the water.
  • Although the cost of a tankless water heater may be more initially, the cost will be recovered in only a few months.
  • Tankless water heaters are known to be less prone to require maintenance than the tank type. Since there are fewer parts to maintain, the likelihood of breakdown is less.Tankless vs Tank

Considerations

When considering whether a tankless water heater or a storage tank water heater is the best option for your needs, there are typically two aspects that are taken into consideration. The first hour rate, which tells you how much water you will get per hour during peak usage and the energy factor, which determines the efficiency of the water heater are the main two that should be considered.

The higher the energy factor the more energy being saved, so this measurement is extremely important for those who want to save as much as possible when it comes to water heating costs. Although, the first hour rate is important as well, because this determines how much hot water is received during the times of the most use.

If the household requires a large supply of hot water, the tankless hot water heaters are more suited for this than tank water heaters. Overall, the benefits of tankless water heaters will provide a much more efficient method of supplying this hot water. If the demand for hot water is very high at any one time, then a tank type may be a better option for you. Read other WaterHeaterReviewer reviews by experts here.
