Choosing the Right Water Heater for Your Home
With proper care and maintenance, water heaters can deliver reliable service for a decade or more. The appliance will need to be replaced when it begins to leak or no longer produces a sufficient amount of hot water.
There are several factors that you must take into consideration when choosing a water heater for your San Jose home.
Determine the Correct Capacity
Before selecting a water heater, you will need to determine the amount of hot water that your family uses. Add one to the total number of people living in the residence. Multiply the total sum by 12.
The result is the first-hour rating or the amount of hot water that the appliance should make during the first hour that a faucet is open.
A tankless, or on-demand, water heater is rated based on gallons per minute (GPM) that flow from a single faucet. Determine the number of hot water faucets that typically operate at the same time.
Multiply this number by three, which is the average GPM flow rate of a faucet. The result is the heating capacity rating of the tankless unit.
Traditional or Tankless
Traditional water heaters are equipped with a large tank that stores heated water, which requires sufficient space. Gas models also need additional space for air to circulate around the burner unit. If you do not have the space to install a traditional model with the correct size storage tank, consider a tankless unit.
This appliance requires less space because it does not store water. They heat water only when a hot water faucet is open. Although more expensive than standard water heaters, tankless units are more energy efficient as they do not continually heat and reheat water in a storage tank.
Whether you select a water heater with a storage tank or a tankless unit, you will have to decide what source of energy it will use to heat the water. Both types of water heaters can be powered by electricity, propane or natural gas. The power source will be determined by the utilities that are available in your San Jose area.
Electric models are less expensive to purchase and install. Gas models contain a burner unit that needs to be properly vented. They may also be more efficient and cost less to operate.
Check the energy rating on the water heaters to determine the most energy and cost-efficient design for your particular application.
