Water heaters are a costly investment for homeowners. When it’s time to equip your new home, or replace your old water heater, it’s important to consider cost, efficiency, and longevity of your new water heater.
Tankless, also known as on-demand water heaters use high-powered burners to rapidly heat water as it runs through a heat exchanger and deliver it directly to your faucets or shower without storing it in a tank. Tankless water heaters are usually powered with electricity or gas. These types of water heaters were found to be 22 percent more energy efficient on average.
In a tankless setup, cold water flows through a heating element in the unit. Whenever a hot water source is turned on, the cold water flows through the heating element, and it heated instantaneously by either gas or electricity. When the hot water tap is turned off, the cold water ceases to flow through the heating element, and the hot water stops flowing.
Which Water Heater Is Right For Me?
The best person to help you make that judgment is an experienced plumbing contractor. Despite this, you can use the following guidelines to help you decide which water heater to buy if your system goes south.
- If long term savings is your top priority, go with a tankless water heater because the long-term savings can balance out the higher upfront costs.
- If you’re short on cash right now, go with a traditional tank-type water heater because the up-front installation costs are usually lower.
- If energy savings is your top priority, go with a tankless water heater because the tankless design eliminates the need to continuously work to keep your water supply heated.
- If you use less than 40-50 gallons of hot water daily, go with a tankless water heater as you won’t be affected by the limited flow rates as much.
- If you use more than 40-50 gallons of hot water daily or use appliances in your home that use a lot of hot water simultaneously, go with a tank-type water heater as these water heaters have higher flow rates.
