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. 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.

  • Decent water heater but no finishing parts included
Size: 10 Gallon Style: Direct Spark Ignition & Incoloy Electric...
Box did not appear to be damaged. But the aluminum ring on the outside of the water heater was severely bent. Had to hammer it back into shape. Water heater does NOT come with the two necessary 1/2 inch 4" long copper connectors needed to connect to the hot/cold water lines. Also, does NOT include the trim for when the water heater is installed, nor the front cover panel. Be aware! ... show more

  • Replaced 10G Atwood - zero complaints
Size: 10 Gallon Style: Direct Spark Ignition & Incoloy Electric...
Very happy customer here! 2 day shipping, super good price, and fully functional. I bought a “slightly used” model and it was new in box, tape still on it. The box was just old and beat up, you could tell this thing got lost in a warehouse. Not complaining - the box is trash, just mentioning it is to be expected if you’re saving hundreds of dollars. Same dimensions and similar wiring/plumbing as my 10 gallon Atwood gas/electric. Skills required: - basic knowledge of wiring diagrams - gas plumbing - water plumbing - rough carpentry - caulking with masking tape I am a experienced mechanic, and it took me about 5 hours from start to finish. That said, I did read the manual online before it arrived and picked up new fittings and adapters at Ace. If you hire a mechanic to change it, they will likely charge you two days of labor and that is fair. ***There is a on/off toggle switch on the outside panel. Ensure it is set to off until you have water in the tank, you risk burning out your heating element otherwise*** Just take the time to read through the instructions.
