Buying Guide
Choosing the right point of use water heater involves a few considerations. Here’s what to keep in mind.
Flow Rate:
Figure out how much hot water you need. A showerhead uses about 2.5 gallons per minute (GPM). A faucet uses less. Match the heater's GPM to your needs. If you need hot water for multiple things at once, get a higher GPM model.
Electrical Requirements:
Tankless heaters need a lot of power. Check your electrical panel. Make sure it can handle the heater's voltage and amperage. If not, you'll need to upgrade your panel. This can add to the installation cost.
Size and Installation:
Consider the space where you'll install the heater. Mini-tank heaters fit under sinks. Tankless models mount on walls. Professional installation is often needed for tankless heaters. This ensures safety and proper function. Always follow local codes.
Energy Efficiency:
Look for models with high energy efficiency ratings. Tankless heaters only heat water when you need it. This saves energy compared to traditional tank heaters. Over time, the savings can add up.
Budget:
Point of use water heaters range in price. Factor in the cost of the unit and installation. Higher-end models have more features and last longer. But a basic model might be enough for your needs.
