Product 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 a node rod to "absorb" the electrolytical action - just like your water heater at home. In fact, when a Suburban porcelain-lined tank is properly maintained, saving 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. Six gallon Suburban gas water heaters feature 12,000 BTUH input and a recovery rate of 10.2 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.

Exactly what I needed

Reviewed in the United States on April 23, 2024

Size: Direct Spark Ignition & Incoloy Electric ElementStyle: 6 GallonVerified Purchase

I needed to replace a 26 year-old manual-light (with a match/lighter) water heater and wanted one that would light automatically and also have a 110v heating element and be the same physical size as the one I was removing. This water heater is exactly all of that. Although the installation took all day, that was primarily because I had to add another circuit breaker & switches (there were none before), and pull/feed/and hide both 110v and 12v wiring. The water heater, itself, is the same size, fit the hole and space exactly, and, after triple checking the electrical and gas connections, works flawlessly.

Wiring a little different from original

Reviewed in the United States on May 14, 2023

Size: Direct Spark Ignition & Incoloy Electric ElementStyle: 6 GallonVerified Purchase

I was a little skeptical when it arrived as it was not well packaged and was worried about damage. Wiring was off from the original, as it only had 3 low voltage coming off the control box and the new one only had 3. Turns out the 4th wire on the old was a second ground. As there were still 4 wires coming out of the trailer, I just wired 2 grounds to the 1 ground wire from the heater. Fires up first shot with no issues. Otherwise installation was pretty easy. Happy with the price and product.

HOT HOT WATER, if it's not a song, it should be.

Reviewed in the United States on April 25, 2024

Size: Direct Spark IgnitionStyle: 6 GallonVerified Purchase

The trailer originally came with the Suburban SW6P - Manual Pilot light only. After swapping the pilot and thermocouple assembly, which dang near burned down the trailer because it became defective, I bought this, the SW6D. The trailer was not wired for it. So, I purchased a Suburban switch with the reset light on it, swapped the shroud and door from the old water heater. I then ran two grounds and a hot to the power distribution center, then followed the wiring schematic, made the water connections, leak checked, made the wiring connections, then gas and leak checked that, then installed a 3AMP fuse on the new slot on the electrical panel and flipped the switch. The reset light stayed on an uncomfortable amount of time but then went out with the distinct sound of the water heater igniting. It shut off, and the reset light came on about three more times on it's own likely due to air in the gas lines, even though I purged all that through the stove right above the water heater. Anyway, the water gets very hot, very fast, and it's been running a couple weeks now with no issues. Previously it would need to be relit several times a week. It's nice having the switch inside too.

This is the second RV water heater we have purchased and both rusted and leak within months of use. These parts are garbage. I have a plumber who helped install both and I made sure to flush and check the anode rod every few months but this product is awful. I would suggest looking for a different brand.

Size: Direct Spark IgnitionStyle: 6 GallonVerified Purchase

The tank installed easy enough , (i used the old circuit board because it still worked), but the hot water tank does come with a new circuit board. You will need to use the old fittings from the old hot water tank or better yet , it would be worth it to install a bypass kit , (which you can buy on Amazon) , it should be installed before you put the hot water tank in, I also ordered a cover kit that had all the hardware needed , ( the Suburban 6261APW Polar White ) and a roll of Dicor (BT-1834-1) 1/8" x 3/4" x 30" Butyl seal tape , to keep moisture out .
This product is good and made to replace the old tank , but if you are not handy at do it yourself projects , get a professional to do it .
