Explore the best of US Craftmaster gas water heaters that are Energy Star compliant, have the longest warranty, high recovery rate and First Hour Rating, and utilize either power vent, direct or atmospheric vent.
US Craftmaster gas water heaters with the water storage tank are built in several sizes, ranging from the lowest tank sizes of 30 gallons to 100-gallon heavy duty models. Most of the models come with the industry standard 6-year warranty while there are some models with the 9-year or long 12-year warranties, such as the models with the pressurized combustion chamber from High Efficiency group.
Note that only High Efficiency Pressurized Combustion, Energy Star Atmospheric and PowerFlex models - available with the direct and power venting system, and sizes of 40-gal and 50-gal are Energy Star approved. The energy factor of these models is 0.67 or higher, (on other models EF is from 0.58-0.62).
The selection of US Craftmaster gas water heaters is quite decent, but the focus will be on the best models that are Energy Star approved:
High Efficiency Atmospheric
PoweFlex FVIR (power and direct vent models)
Direct Vent FVIR
Ultra Low NOx FVIR
Water heaters for Mobile Homes
What makes this group of gas water heaters interesting is the patented air intake system built on the side of the heater, responsible for making the pressurized combustion chamber, also the specially designed flue baffle that helps in keeping the heat inside longer - resulting in high efficiency factor (EF) of 0.7. Combined with the "Green Choice" or eco-friendly gas burner, the heater is able to meet the strict low for greenhouse gas emission.
As opposed to many other gas models, especially standard type heaters that use the pilot light, this model utilizes the hot surface igniter that is more durable and reliable.
Also, except the simple gas valve and its LED diodes for diagnostics, these gas water heaters include a small but user friendly LCD display where the operator can see the existing temperature or during the malfunctioning - a service code.
For protection, US Craftmaster utilize the inner lining, powered and non-sacrificial anode rod for long-term operation and Sta-Kleen diffuser tube that helps in reducing the sediment and limescale buildup.
This unit comes with the 12-year warranty and is Energy Star compliant.
US Craftmaster gas water heaters from the Energy Efficient series offer more flexibility when it comes to the warranty; the buyer can get models with the 6-year or 9-year warranty. These are designed in two sizes which are also the most popular; 40- and 50-gallon.
What makes these gas water heaters to provide higher energy efficiency is the automatic flue damper, which is controlled by the micro-processor located inside the electronic gas valve, that closes when needed and therefore keeping the heat energy longer inside the heater.
Some of the advanced features found on US Craftmaster gas water heaters include the commercial-quality electronic gas valve with the Intelligent Control and microprocessor for better performance, accuracy and control. The Intelligent Control also allows the self-diagnostics so the user can be notified for any problem through the LED indicators.
The best models do not utilize the most common pilot light - no manual lighting, but the integrated and durable thermopile allowing self-power operation, a great benefit during the power outage.
Safety and protective features such as the self-cleaning dip tube that is design to reduce the sediment and limescale buildup, heavy duty anode rod for protection against the metal tank corrosion, automatic shut-down system during the air supply restriction or overheating and the Flame Lock Safety System as part of the FVIR system - protecting against the accidental fire outside the combustion chamber and in presence of the flammable vapor.
As it was mentioned, gas water heaters from the US Craftmaster manufacturer are available in several sizes, with more or less advanced models and for every budget. Cheaper models are simpler and do not meet the Energy Star standards, while the more expensive ones are opposite; they include the advanced and durable elements, have longer warranty and can save energy, while being the environment friendly. All models are meant for domestic water heating, but there are some heaters that can work in combined space heating and potable water heating, and also in solar heating system, for water storage or as a backup.
