There are a number of possible benefits to buying a tankless water heater. Though the initial cost of purchase is higher than a standard water heater, the long-term savings potentially make up for those first out-of-pocket expenses. A demand water heater also saves energy because it only heats the water as it is needed for use. In your research on tankless water heaters Pleasanton CA, it is important to consider the heater’s energy source options, size and flow capabilities, and energy efficiency to ensure you get the greatest benefit from your investment.

Energy Source Options

Demand water heaters can be either electric or gas-powered. Gas is typically a cheaper energy source, but not all homes are set up for gas appliances. If gas lines need to be installed along with the unit itself, the initial costs will rise accordingly. Another consideration is whether the appliance has a constantly running pilot light, which would reduce the energy efficiency of the tankless water heater.

Size and Flow Capabilities

Knowing how much water your household uses is an important factor in determining the size and flow rate you will require. Gas-powered units tend to have higher flow rates than electric, but a single heater still might not provide all the water needed when there are multiple demands for water at the same time.

Energy Efficiency

Tankless water heaters come with energy ratings that are based on the amount of energy needed to power the unit versus the amount of energy output. According to energy.gov, homes that use 41 gallons of water or less per day get the highest rate of energy efficiency, though even for homes that consume higher amounts, efficiency can be increased through the installation of multiple units.

Understanding your home’s water usage patterns will help you to choose the tankless water heater with the appropriate energy source, size and flow capabilities, and energy efficiency to meet your needs.
