Traditional tank water heaters
Tank water heaters are a traditional choice for producing hot water for your home. But, if you haven’t replaced yours in a while, you’ll be surprised at how efficient newer models have become.
Tank water heaters: how they work
Traditional water heaters are straight-forward devices: Cold water coming into your home is stored in a tank water. Then the water is heated by electricity, natural gas, propane, heat pumps, and even solar energy. When the water in the tank cools off, the fuel kicks in and heats it up some more. When you turn on your shower, faucet, dishwasher, or washing machine, hot water is ready for you to use.
Are tank water heaters still right for you?
Tankless water heaters are an increasingly popular option. But, is one right for you? That depends how much water your house uses in an hour. Hot water tanks are measured by their one hour peak capacity. Suppose everyone took a shower and turned on every hot water tap at the same time. How much water would you need for an hour? That’s how many gallons your water heater has to hold.
On the other hand, tank water heaters are not the most efficient choice available. That’s because they heat and reheat water around the clock–even if you don’t use it. Tankless water heaters, meanwhile, only heat water when you need it.
Your water heater of choice
The type of water heater you select is a matter of personal choice. Factor in your demand for hot water, the cost differential between a tank and tankless unit, the cost of operating each and how long it will take to realize a return on your investment.
The longer you plan to stay in your current address, the more a tankless water heater makes sense. If you’re planning a move with in five to seven years, it’s possible sticking with a tank water heater is your better choice.
