Rheem Fury 22V40F1 Water Heater Review

Before we begin reviewing the key features of this product, it’d be noteworthy to mention here that Rheem Fury 22V40F1 40 gallon water heater is an old model and has thus been discontinued for sale in the market by the company. Nonetheless, the model has swiftly been replaced by a newer and equally efficient version – Rheem PROG40-38N RH59 – 40 gallon water heater. Here we review the best and perhaps not-so-good features of this new model to help you with your purchase.

Key Specifications

  • Energy saving – emits low carbon and is a relatively environment-friendly burner
  • Warranty – The heater is equipped with a Rheum exclusive registered R-Tech anode rod that offers tank protection for longer; 1 year warranty covering all parts and components of the appliance

Highlighted Features

1. Design

The water heater has a low Knox design to comfortably meet continual hot water requirements of up to 40ng/J Knox. Also, the heater can be lit up quite easily, without the need for any matches. The water heater is 601/4” tall, weighs 130 pounds and measures 20 x 20 x 50 inches. Peaking at similar dimensions, you can even refer to our take on Bradford White gas water heaters as a competent alternative. 

2. R-Tech technology

This Rheem water heater model has a registered anode rod that comes with Rheum exclusive R-Tech technology which facilitates long-lasting protection to the water tank. Also, the EverKleen patented system helps prevent any build-up of sediment in the water heater despite regular wear and tear.

Since the drain valve functions easily, the amount of lead in the system is found in relatively less quantities than other water heaters in the market.

Final Verdict

Rheem PROG40-38N 40 gallon water heater currently outweighs all other similar models in the market. Equipped with some of the best features of high-end models but at a price that comfortably suits every pocket, this product appeals all kinds of customers. Another area where this appliance scores over its contemporaries is the lead emission. Where most other devices make use of higher amounts of lead in the heater’s heating element, which is extremely harmful to both the skin and the environment, Rheem scores a point here.

The brand has managed to maintain the lowest amounts of lead usage in its product so that customers are protected against harmful chemicals during bathing, washing dishes, or doing the laundry. This is in comparison to other water heater types. As such, the product does seem like a great buy at this price.

When you decide to go buy a water heater for home use, you’re bound to find options aplenty in the market. To make things more confusing, they come in varying sizes which can easily put you in a fix as a customer. What size of the water heater would be ideal for your home needs, you’d wonder? Here’s how we can help:

  • 30-40 gallons – ideal for 1-2 persons
  • 40-50 gallons – ideal for small families of 2-3 people
  • 50-60 gallons – ideal for a family of 3-4 persons
  • 60-80 gallons – works best for large households comprising 5 people or more

Hope this chart helps to determine the right capacity size of water heater to buy for all your hot water needs at home. Besides the capacity, of course, there are few other important points to consider as well such as material, lead usage in heating element, emission, energy efficiency, and price of the model. Also, it’s better to always look up online reviews of every product or model that you intend to purchase. On a different note, if you’re a small family, you could even get away with a tankless water heater and save up some space. 

Wrapping Up

A water heater appliance is an expensive product and usually one that’s set up for a long time to come. You wouldn’t keep changing it every few years until it requires replacement due to excessive wearing off. This is why it’s important to buy one only after a careful assessment of the points detailed above. Once you’re convinced, go ahead and set up a water heating device in your home to make life comfortable when you’re cold. Of course, Rheem leads the way at the moment and as stated in this post is currently a great buy.

  1. Actually, a question.
    My home has a Rheem 21v40-7 water heater. Can you tell me how old it may be? We are considering whether to replace it. We bought home 17 years ago from original owners(built around 1965). Not sure if it is original equipment. Thanks very much!
