Thermal Efficiency
A water heater's thermal efficiency refers to its ability to convert energy into heat. Look for a tankless or hybrid water heater that offers high thermal efficiency, typically above 90%. This will help you save money on your energy bills and reduce your environmental impact.
Capacity
The capacity of your water heater is measured in gallons per hour (GPH). Choose a tankless or hybrid water heater that meets your household's hot water needs. A higher capacity will provide more hot water, but it may also increase energy costs.
Durability and Reliability
A water heater's durability and reliability depend on its construction, material, and maintenance routine. Opt for a tankless or hybrid water heater made from high-quality materials like stainless steel or copper. Regular maintenance will help extend the lifespan of your water heater.
Safety Features
A water heater must meet safety standards set by the U.S. Environmental Protection Agency (EPA). Look for a water heater with built-in safety features like automatic shut-off, overheat protection, and thermal cutoff. This will help prevent accidents and ensure your home's safety.
