Rheem high efficiency gas water heaters are designed to heat water efficiently while reducing the energy consumption, saving you money and providing the environment-friendly service. Explore the Energy Star models and its top features.

Rheem manufacturer designs and produces an extensive line of gas water heaters for high efficient heating, and so far there are nine groups. Power-vented models are all energy efficient, while from the atmospheric vent units, only those with the powered damper:

XR90

A model 43V30-60 is the 29-gallon gas water heater that is design to provide high energy factor of 0.70, which, with the 60,000 Btu gas input, First Hour Rating of 90 GPH and recovery rate of 61 GPH, outperforms the standard 50-gallon unit. It is built with the smaller footprint to save space and allow easy installation.

It is equipped with the Guardian system (FVIR compliant), has the EverKleen system to reduce the mineral deposits, self-diagnostic system and eco-friendly burner for low NOx gases, and has connections that allow the potable water and space heating. Warranty is 6 or extended 10 years.

Professional Powered Damper

All Rheem high efficiency gas water heaters from Professional series are Energy Star compliant. Models are available in several sizes, short and tall, and with the capacity from 38 to 50 gallons. The main component is the 24-volt powered damper that enhance the heat transfer by trapping the heat inside the flue. The water heaters are equipped with the advanced components, such as the self-diagnostic and Guardian system.

High Efficiency Condensing Power Direct Vent

The HE condensing group has two models whose energy factor is the highest of all Rheem high efficiency gas water heaters, 0.80. These FVIR compliant units are using the Power Vent or induced draft system with the vertical and horizontal termination for more flexibility. What makes them different from the standard tank-type heaters are the submerged helical condensing heat exchanger for the increased efficiency and two anodes for extra protection against corrosion. Other great features include the eco-friendly burner, self-diagnostic system and long lasting silicon nitride igniter.

As the water heating accounts for approximately 15-20 % of the total home energy usage, and since the high deficiency water heaters use up to 50% less energy than standard models (either tankless or tank-type), it is more than obvious why high efficient models are popular and recommended.
