If it’s time to replace your storage tank water heater, or if you’re maximizing energy savings by upgrading appliances, it would be wise to consider tankless water-heating systems for up to 50 percent water-heating savings, a water heating system that’s customized for your needs, and to enjoy an endless supply of hot water on demand.
Tankless water heater savings
Tankless water heaters provide instantaneous hot water without standby heat loss, as with storage tank water heaters, which lose as much as 75 percent of the energy consumed to heat and reheat stored water. In contrast, a tankless system employs a powerful heating element that heats and provides an endless supply of hot water if your system is correctly sized.
Two key factors
To maximize water-heating efficiency and reach greatest savings, your tankless water-heating system needs to be properly sized, which includes calculating flow rate and temperature rise.
- Flow rate is calculated by measuring the amount of water in gallons per minute that each hot-water application in your home supplies. To get the flow rate for your entire household, combine the flow rates of the maximum hot-water applications in use at one time.
- Temperature rise is the total degrees that inflowing water requires heating to reach the desired hot-water temperature. For homes with more than one tankless unit, temperature rise should be calculated for each unit for maximum energy savings and ample hot water supply.
Customizing your system
Tankless water heaters are available in different sizes, which allows customization to your home’s flow rate and temperature rise. For instance, you may choose to install a medium-sized unit for the dishwasher and kitchen sink, a small unit for a remote utility sink and a large whole-house unit for clothes washing and bathrooms. It’s important to work closely with your heating and cooling professional to install the perfect system customized for your home.
