High Efficiency
Gas Water Heaters

An overview of the high efficiency gas water heaters built by the major manufacturers of water heating products in US and Canada. Check out the available types and models, capacity and energy factor of the gas-powered tank-type water heaters.

All the listed high efficiency water heaters below are also Energy Star approved which makes them eligible for the rebates and tax breaks. One water heater is considered Energy Star as long as its EF and First Hour Rating meet the requirements.

High efficiency means that more energy is transfered to water, less energy is lost and less carbon dioxide emitted.

The EF or energy factor is used to measure the efficiency of the water heater and higher it is, lower the operating costs are. Bigger the number, more efficient model is.

Keep in mind that water heaters with the higher energy factor cost more, but save more energy and money in the long run and when compare to the standard-type models. According to energystar.gov high efficiency gas water heaters use 10-15% less energy than conventional models.
