Key Factors to Consider When Choosing a Tankless Water Heater

Before you buy, carefully consider these important factors:

1. Flow Rate (GPM): Gallons Per Minute

This crucial specification indicates how much hot water the unit delivers per minute. Higher flow rates are necessary for households with multiple bathrooms or high hot water usage.

2. Energy Efficiency:

Look for units with high energy factor (EF) ratings. A higher EF rating means the unit uses less energy to heat the same amount of water.

3. Installation Requirements:

Some units require professional installation, while others can be DIY projects. Consider your experience level and comfort with plumbing before making a purchase.

4. Recovery Rate:

This refers to how quickly the unit can reheat water. A faster recovery rate is ideal for large families or those with heavy hot water demands.

5. Size and Space Requirements:

Tankless water heaters are generally smaller than tank water heaters. Still, ensure you have enough space for the unit and associated venting.
