From storage to tankless options, understanding the right vocabulary will ensure you make an informed decision. Lets embark on this informative journey.

1. Storage Tank Water Heaters

The most common type, "storage tank heaters" (also known as electric or gas-powered) are represented by "WH" or "WHR". They store hot water in a large tank for immediate use. Key factors to consider include:

• Capacity: Measured in gallons (GPM or GCF), like "60-gallon capacity" - this refers to how much water it can heat.
• Type: Electric ("electric WH") or Gas ("gas-fired WH") - choose based on your homes energy source preference.
• Efficiency: Look for Energy Star-rated models with high Annual Fuel Utilization Efficiency (AFUE) ratings.

2. Tankless Water Heaters

Tankless, or "instantaneous" water heaters, are denoted by "on-demand" or "tankless WH." They heat water as it flows through the unit:

• Flow rate: Indicated in GPM, like "5 GPM" - the volume of water they can heat per minute.
• Continuous circulation systems (CCWH): Maintain a steady supply by circulating water through the unit.
• Advantages: Save space and energy, but may require more maintenance.

3. Safety and Environmental Considerations

Important safety features to be aware of include:

• Temperature and pressure relief valves (TPR or TV)
• Flame safeguard (FSG) or pilot flame safety (PFS)
• Green options: Look for Energy Star-labeled models that minimize environmental impact.

4. Installation and Maintenance

Consider the installation requirements and ease of maintenance:

• Type of connection: Gas connections may need professional installation, while electric ones are DIY-friendly.
• Warranty: Longer warranties indicate better quality and reliability.
• Service accessibility: Ensure the model is easy to service if needed.

5. Cost and Energy Efficiency

Costs can vary based on purchase price, operating costs, and lifespan:

• First cost: Initial investment for the appliance.
• Operating costs: Compare energy consumption rates and annual energy savings.
• Payback period: Estimate how long it will take to recoup the initial investment through energy savings.

By familiarizing yourself with these key terms and factors, youll be well-equipped to select the perfect water heater that suits your needs and budget. Happy shopping!
