Water heaters or geysers are essential parts of our houses. They are usually installed in most bathrooms and kitchens across the globe, especially in colder countries. If you are someone who is considering purchasing and installing one, then you must know that there are two major varieties. These are

  1. Tankless water heaters-Tankless water heaters are the relatively newer appliances which heat water instantly. These types of water heaters heat water only when you turn the faucet on.
  2. Tank storage water heaters- Tank storage water heaters are the traditional water heaters that you see hooked up on walls in bathrooms and kitchens.

Before purchasing, you must be familiar with the detailed comparison between the two. This helps  you make an informed decision depending upon your budget and usage criteria. The following are some points of comparison between tankless water heater vs. tanks storage water heater:

1.Usage and Working

Tankless Water heaters-A tankless water heater makes use of a heat source such as electric or gas to heat up water on demand and instantly. The water is heated exactly when needed. In case of tankless water heaters, as the hot water tap is turned on, the cold water travels through a pipe into the unit. Here either an electric element or the gas burner heats it and you thus get instant supply.

Tank Storage water heater-A traditional tank storage water heater is meant to store and preheat water( about 35 to 50 gallons) in a tank. The preheated water in this case can be used whenever someone needs. A gas burner or electric elements under the tank heats the water in the tank and this hot water is released when you turn the hot water tap.  To replace the hot water used, cold water replaces it and enter the bottom so that the tank is always full.

    Tankless water heaters and tank storage water heaters both heat water for household use, but they have different features that make them ideal for different applications. Tankless systems are significantly more expensive than tank storage systems, but they often require less physical space and can pay for themselves in energy savings over time.

    Houses with larger families or extended households may benefit from the higher quantity of hot water that tanks provide, whereas those with a smaller number of occupants may appreciate the convenience of being able to run only cold-water cycles during hours when no one will be home. Tankless systems generally include a larger upfront cost than tank storage units, although they also have lower ongoing costs and do not need to be replaced as frequently.

    Since we must maintain and monitor both an electric and gas water heater, I figured I would comment on many of the reasons I prefer the electric option. Additionally, I would like to connect all the piping and replace both tanks with a single unit as they are both over 10 years old.

    You forget the installation cost when replacing a tank with a tankless water heater. This might include running a new main gas line if a larger total supply is needed. I don’t know about propane the above is based on natural gas.
