**Residential-grade condensing storage tank water heaters
Heating water typically takes between 20 per cent and 35 per cent of your home’s total energy use. So it makes sense to install the most efficient model you can afford. Natural gas water heater efficiency is usually measured by an energy factor (EF) rating. The higher the EF rating, the more efficient the water heater. To qualify as ENERGY STAR gas-fired water heaters must achieve a minimum 0.67 EF rating.
ENERGY STAR® non-condensing storage tank models have an EF between 0.67 and 0.70 making them more efficient than standard storage tank models (typically between 0.50 and 0.62 EF) operating in many homes today. As these models aren’t as efficient as tankless and/or condensing technology, their price point is more affordable. However, while some model numbers are similar, efficiency ratings may differ. Please check our qualifying water heater list prior to making your purchase.
