How to Choose the Right Water Heater
Fuel Type
Electric heaters are cheaper upfront but cost more to operate. Gas models save long-term but need proper venting. Heat pumps and solar options offer eco-friendly alternatives.
Size & Capacity
A 40-50 gallon tank suits most families, while tankless units require a flow rate assessment (e.g., 8 GPM for two showers). Oversizing increases energy waste.
Efficiency Ratings
Look for ENERGY STAR® labels and Uniform Energy Factor (UEF) scores. Higher UEF = lower bills. For example, Rheem’s UEF 3.7 heat pump outperforms standard 0.65 EF tanks.
