• Look for heaters with sufficient flow rates (GPM) to meet your household’s hot water demands.
• Tankless heaters generally have higher flow rates than traditional tank-style heaters.

Energy Efficiency

• Look for heaters with self-modulating or energy-saving features that adjust power consumption based on your hot water needs.

• Consider the potential energy savings and long-term cost savings when evaluating the initial cost of the heater.

Installation and Electrical Requirements

• Tankless heaters often require more complex electrical installations, with specific breaker and wiring requirements.
• Ensure your home’s electrical system can accommodate the power requirements of the heater you choose.
• Consider hiring a licensed electrician to handle the installation, especially for high-powered tankless models.

Safety and Durability

• Look for heaters with safety features like overheat protection, leakage protection, and dry-fire protection.

2. How energy-efficient are tankless water heaters compared to tank-style heaters?

Tankless water heaters are generally more energy-efficient, as they only heat water when it’s needed, rather than continuously maintaining the temperature of a storage tank. This can lead to significant energy and cost savings over time.

3. What are the installation requirements for a tankless water heater?

Tankless water heaters often require more complex electrical installations, with specific breaker and wiring requirements. It’s recommended to have a licensed electrician handle the installation, especially for high-powered models.

4. How do I determine the right size of water heater for my home?

The size of the water heater you need depends on the hot water demand in your home, which is influenced by factors like the number of water points, the number of occupants, and the type of appliances you have. It’s best to consult with a professional to determine the appropriate size based on your specific needs.

5. What safety features should I look for in a water heater?

When choosing a water heater, look for features like overheat protection, leakage protection, and dry-fire protection to ensure the safety and reliability of the unit. Additionally, opt for heaters that are ETL-certified or have other safety certifications.
