Checking Out the Rheem Water Heater Web Site

Rheem Water Heaters

The first thing I noticed is that Rheem is number 1 on Google when you search for “water heaters”. They must be doing something right.

After looking over all of these hot water heater sites, they are getting pretty boring. However, Rheem does have a nice looking site and easy to navigate. There are some interesting things that I haven’t noticed at the other sites though. For instance, Rheem makes heat pump water heaters! Don’t run across them very often!

Heat Pump Water Heaters

Heat pump water heaters work just like your air conditioner, taking heat from the air around the heat pump and putting into the water. Since the heat pump is just moving heat energy from one place to another, it consumes much less energy than just heating the water up.

The warmer the ambient air temperature the more efficient they are, but if the ambient air temperature drops to around 40 degrees there just isn’t enough heat in the air for the heat pump to work effectively.

An energy factor of .9 is considered pretty good, where as the Rheem heat pump water heater has an energy factor of 2.0!

Solar water heating

Rheem seems to have a little of everything. They have several models of solar water heaters, both passive and active designs. They have all the specs and details you would ever want to know as well. And as you could assume, they have backup solar storage tanks with heating elements.

The Marathon water heater is interesting.

It’s a non-metal electric water heater. It has a plastic tank wrapped in fiberglass and other stuff. No metal to rust, and what they call a lifetime tank warranty.

It has two and a half inches of insulation which allows only 5º F heat loss in 24-hours! Other advantages include not needing an anode rod, so you don’t need to worry about smelly hot water. That rotten egg odor will not infect this tank.

It comes with a factory installed T&P (temperature & pressure relief) safety
valve and 4 feet of pipe insulation.


Tankless Water Heaters

Rheem also has a line of tankless water heaters. Typical sizes and energy factors comparable with the rest of the industry.

I did see a few features I wasn’t familiar with and have not seen with other models or brands, but then they might exist and I just haven’t run across them before.

They say they have a special cable to link two units together to operate as one for when you have for instance, really cold incoming water etc. The other related item is the ability to link up to 20 heaters using an optional manifold control assembly.

Probably wouldn’t need to do anything like that in a residential setting. LOL

Well that’s about all I’ve got for Rheem water heaters and the Rheem web site.

Later… Bill the Hot Water Guy
