## Overview

The Suburban Advantage SW12DEL is a 12-gallon RV water heater featuring a durable porcelain-lined steel tank, 12,000 BTU gas heating with a 10.1 GPH recovery rate, and an optional 1,440W electric element for versatile power options.

## Description

The best water heaters on the road today, Suburban's line of water heaters includes high recovery gas, gas-electric and motor aid models with sizes and features to match the requirements of almost any RV. Heated water attacks all metals, but not porcelain. That's why Suburban uses a porcelain-lined, steel water heater tank with an anode rod to "absorb" the electrolytical action - just like your water heater at home. In fact, when a Suburban porcelain-lined tank is properly maintained, it saves the owners the cost of premature replacement. In addition, every Suburban tank is pressure tested twice during the manufacturing process to ensure its integrity. Fast recovery means more hot water and fewer cool water cycles. 12 gallon Suburban gas water heaters feature 12,000 BTUH input and a recovery rate of 10.1 gallons per hour - that's the fastest in the industry. The insulation is available for this product. Also light indicator is available for this product.

## Features

- DURABLE CONSTRUCTION: Engineered with a porcelain-lined steel tank, the Suburban 12 Gallon Tank Water Heater is designed for durability, mimicking the longevity of residential tank water heaters, ensuring years of reliable hot water.
- ADVANCED CORROSION PROTECTION: Equip with a replaceable anode rod and this water heater provides enhanced protection against tank corrosion. The anode rod also doubles as a drain, simplifying maintenance and extending the lifespan of the unit.
- FLEXIBLE POWER OPTIONS: Featuring an optional electric element, this allows you to utilize campsite or generator power for heating water, offering unmatched versatility.
- EXCLUSIVE HEAT TRANSFER TECHNOLOGY: Suburban's exclusive flue tube design slows the combustion process, optimizing heat transfer and ensuring the water in the tank heats efficiently, saving energy and providing hot water faster.
- SPECIFICATIONS: Product Dimensions - 16.22" x 16.22" x 22.25"; Cutout Dimensions - 16.38" x 16.38" x 22.25". BTU/h - 12,000. Optional electric element input - 1,440.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Exact same without any mods except no on-off switch.
  

*by A***R on Reviewed in the United States on December 17, 2022*

Exactly what I ordered and was well packaged.  No modifications were required to install and even the connections were the same. Wire colours were even the same.When finished installing and filling with water I couldn't wait to try out the gas as with my previous heater it would run perfectly for 1 fire up then require reset before it would fire again.I went in the rv and turned it on. I had to check for leaks so kinda got busy too. I asked my wife if she heard it fire and she as well as myself couldn't hear it. Damn. I went out and checked and sure enough it was operating as it should. Wow quiet to boot.All in all we are totally satisfied with this heater.

The installation ease depends on the RV you put it into, my Montana required a lot of work.

    Best purchase I Made!
  

*by H***Y on Reviewed in the United States on March 11, 2022*

Words cannot express how grateful I am for this seller to have this product available and shipped out the day we ordered it! We fiddled around with a local rv dealership, they said they ordered the water heater and 2 weeks later it was never ordered! Found this seller selling this product on Amazon and it was shipped quick and we received it within 3 days! My family had been without hot water for 2 weeks! Beyond greatfull for the seller sending this ASAP! And it was easy to install! Thanks for this awesome product and super quick shipping!
