How do I ensure that I get the right tankless water heater for my home?

Getting optimal performance from a new ENERGY STAR^® certified tankless water heater depends on more than just choosing the right equipment.

• Consult with experts: Ask your builder or energy advisor how this ENERGY STAR certified feature could transform your home.
• Buy Quality: Look for an ENERGY STAR certified tankless water heater to ensure a quality system.
• Size your system correctly: To provide your household with enough hot water and to maximize energy performance, you need a properly sized water heater.
• Ask about costs: Before you purchase a tankless water heater, it’s also a good idea to estimate its annual operating costs and compare those costs with other water heating technologies.
• Maintain your equipment: Similar to servicing a vehicle, preventive maintenance on your equipment is a good investment to minimize future problems. Arrange for annual servicing to keep the equipment free of scale deposits and clean filters. Consult the owner’s manual for more details.
