Which is Better: Tankless or Traditional Water Heaters?

Which is Better: Tankless or Traditional Water Heaters?

If you are considering replacing your water heater, you may be wondering if you should go with a traditional water heater or try a tankless one. You have probably heard that a tankless water heater is more economical and will save you money on your energy bill. While this is true, there is more to the story than how much energy it uses to heat your water. Consider these facts about water heaters before you make your final decision.

Tankless Water Heaters

Tankless water heaters ignite and heat the water as it passes through the pipe. There is no holding tank for hot water. This type of heater is also called an on-demand water heater.

Cost: The initial cost for a tankless water heater is two to three times more than the cost of a traditional hot water heater. Tankless water systems should be professionally installed. According to, households that use less than 42 gallons of hot water per day can save between 24 and 34 percent on their energy costs while households with high water usage save 8 to 14 percent. It further states that an average household can save about $100 per year on energy costs by switching to a tankless water heater.

Convenience: Tankless systems heat water on demand, which means hot water is always available. You may need to run the cold water left in the pipes before getting hot water, but the heater will continue to heat water until you turn off the faucet. This means you won't run out of hot water in the middle of a shower and you don't need to wait for the water in a tank to reheat before someone else can take a shower.

You Could Save 24-43 Percent on Energy Costs by Switching to a Tankless Water Hearter

Traditional Hot Water Heaters

Traditional hot water heaters heat all the water in the water tank and maintain the desired temperature. When hot water is needed, it drains the hot water from the tank and the heating element in the tank reheats the incoming cold water.

Cost: The initial cost and installation of a traditional water heater is less than the cost of a tankless version.  It does require more energy to heat and maintain hot water, however. Expect to pay 8 to 34 percent more in energy costs depending on the amount of hot water used. This typically amounts to about $100 per year or $8 to $10 per month for the average household.

Convenience: If you have teens in your home, you already know that hot water can be depleted quickly due to long showers. When this happens, the shower turns cold. Additional family members need to wait 20 minutes or more for the tank of water to reheat before anyone can take another shower.
