Suburban SW12DE Water Heater Features and Benefits:

Combined Gas & Electric Model

Both the electric and gas fuels have their own set of advantages and disadvantages.

However, combining the two fuel options can help you solve the cons associated with each of them while enabling you to enjoy the best of both worlds.

This is exactly what the SW12De water heater—bringing you the two fuel options into a single unit.

You can choose the gas burner with gas input or around 12000 BTU to offer you recovery of 10.2 GPH or the electric heating element with 1440W and recovery of up to 6 GPH.

Apparently, simultaneously using both the electric and gas options will result in an increased recovery rate of up to 16.2 GPH.

Longer Performance Life

One of the top benefits you’ll enjoy from using this Suburban water heater is its extended service life. This is attributed to the protective elements integrated into it.

One such element involves the anode rod that excellently neutralizes the aggressive water action on the steel tank, providing it with cathodic protection.

That being said, keep in mind that you should only remove this anode rod during an inspection, drainage or when you want to replace it (replace it once every year or whenever ¾ of its weight is gone).

The other protective element revolves around the porcelain lining, a well-known corrosive resistant material that ensures the heated water does not harm the metal tank in any way.

And yes, the fact that the tank itself is made of heavy-duty steel metal hugely contributes to its overall durability and longevity.

Compact, Space-saving Design

This water heater is also loved by many RVers due to its small size which enables it to easily fit in many recreational vehicles without taking away too much space.

As you already know, the space is always limited when it comes to your RV, so having a water heater that takes less space while executing its intended job well is a huge plus.

Hassle-free installation

It’s also pleasing to note that this water heater installs quickly and easily.

It comes with a simple and straightforward design, enabling you to easily figure out which part goes where.

Besides, the package comes with all the installation tools as well as a comprehensive instruction manual.

Frequently Asked Questions:

1. is this water heater the same as the SW12DEL model from Suburban?

Now, the two models are not the same…the key difference is that the SW12DEL has the capabilities of controlling both the electric and gas heating elements inside your RV. This is unlike the SW12DE which is only capable of controlling the gas heating element.

2. what are the exact dimensions of this water heater?

the exact measurements of Suburban SW12DE are: 24 L x 47.6 W x 16.7 D inches

4. can I replace the 6-gallon Suburban heater with the 12-gallon model without any major changes?

Yes, you can switch to a 12-gallon Suburban model without making a lot of changes. This is because the cutout diameter of all the Suburban heaters appear to be the same. Only the heater length extends a little as you move to higher capacities…so you should make sure you have enough space to the back of your heater for the extra length.

5. Does the unit come with anode rod?

Yes, an anode rode comes included in the box ready for installation. Remember this rod helps prevent electrolysis, extending the lifespan of the metallic unit.
