Water heaters are an essential piece of equipment that you rely on to supply you with constant hot water. As a result, when choosing the right system for your home or replacing your existing water heater, it is essential to evaluate its cost, efficiency, and lifespan. Below, we’ve compiled this article comparing tankless water heater vs tank. This will help homeowners decide which system is best for them. Whether it’s tankless or tank water heaters, you now have the information.
How does a tank water heater work?
A tank water heater has a tank that retains the hot water and operates on a warm-rise concept. They are designed in many different shapes and sizes, with most of them using an electric element or a gas burner to heat the water. In any case, their operation is to allow cold water to enter the tank from the main supply which then gets heated based on set temperature. Therefore, whenever you have a demand, the hot water will rise to the top of the tank and flows into your sink, shower, or bathtub as needed.
How does a tankless water heater work?
A tankless water heater does not have a tank water heater. Instead, it heats the water as needed. Most tankless water heaters typically use gas or electricity and have a unique heat exchanger to heat incoming cold water. They operate when you turn on the hot water taps, activating the internal system, which immediately heats the water. The heated water is routed through your pipes to the faucet or showerhead at the desired temperature.

Tankless Water Heater vs Tank
When deciding between a tankless and a tank hot water heater, many factors must be considered.
- The life expectancy of Tankless Water Heater vs Tank
Tank water heaters usually last 10-15 years, while a Tankless water heater can last 20 years or more if properly maintained.
- Tankless water heater vs tank cost
When comparing water heater costs, you must consider upfront installation costs and possible energy savings. Tank water heaters are usually less expensive than tankless water heaters. In addition, when comparing tankless vs tank, Consumer Reports discovered that installation of gas-fired tankless heaters costs $4500-$8500, while standard storage tank types cost $1100-$3500. Furthermore, due to the necessity for electrical outlets, improved gas lines, and a new ventilation system, tankless gas versions had higher installation costs, according to the survey.
- Potential energy consumption of tankless water heater vs tank
When comparing water heaters, it’s crucial to remember that storage tanks have some standby heat loss. (water cools as it sits in the storage tank until needed). It requires heating regularly, even when not in use. On the other hand, tankless heaters do not require this additional energy cost because water is heated when needed. Energy.gov describes the expected energy savings with tankless water heaters as follows:
- For families that utilize 41 gallons or less of hot water daily, tankless heaters can be 24-34% more energy-efficient than traditional water heaters.
- Tankless heaters can save 8-14% more energy than traditional heaters for households that consume about 86 gallons of water daily.
- According to Energy.gov, installing a tankless heater at each hot water outlet can boost tankless water heater energy savings by up to 27-50%.
- ENERGY STAR estimates that utilizing an ENERGY STAR-certified tankless water heater can save a typical family at least $100 per year in tankless water heater energy savings.
- Long-term costs
The cost decreases connected with tankless heaters will vary depending on the circumstances, but the reduced energy demand will result in considerably lower utility bills. According to the DOE, tankless heaters have a longer life expectancy than shot water tank heater, with more than 20 years compared to 10-15 years for hot water tank heater.
- Convenience
If you’re dealing with an emergency replacement of a failing water heater – according to an Energy Efficiency survey, 37% of residents replacing a heater did so due to sudden failure – But keeping the same heater model could speed up the process.
- Speed of hot water delivery
Tankless heaters typically take about 15 seconds to heat water, whereas a fully heated tank can deliver hot water instantly – remember that hot water will need time to travel through the pipes from the heater to the faucet in either case. Some tankless heaters include built-in recirculation pumps, allowing them to provide hot water immediately.
