Suburban SW6DERA Gas / Electric Hot Water Heater (Black Door)

The Suburban line of RV water heaters are the best on the road today and so it's no surprise they are the most installed HWS in Caravans, Pop Tops, Camper Trailers and Motorhomes. The new SW6DERA model replaces the discontinued SW6DEA model.

The Suburban SW6DERA is a high recovery gas and gas-electric HWS. It's compliant with all required regulations and is approved to the WaterMark Certification, Regulatory Compliance Mark and Australia and New Zealand Gas Safety Certification. The Hot Water System features a porcelain lined, high tensile steel tank which is pressure tested twice to assure tank integrity and long life.

This Suburban operates on universal gas & 240V and has a 12V ignitor. The SW6DERA is an automatic model featuring direct spark ignition with a remote switch for on/off control from inside the RV. As with all Suburban models, gas consumption is kept to a minimum making Suburban a super-efficient unit and ideal for long trips away, where gas efficiency is of utmost importance. All Suburban Hot Water Systems have an anode rod that equalizes aggressive water action, providing cathodic protection for the tank. It is a very important factor in tank life and should only be removed for inspection, draining or replacement. The rods are designed to be easily replaced when required.

This package includes a "Black" Service Door. The "White" Service Door package is available as a separate listing. Please note the new service doors are not compatible with the older SW6DEA model and vice versa.

Key Features:

  • Longer Life. 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 electrolytic action - just like your water heater at home.
  • Faster Recovery. Fast recovery means more hot water and fewer cool water cycles. Suburban uses a copolymer insulation jacket specially moulded to fit the tank which does a better job of retaining heat than some other models. For higher recovery, both the gas and electric element may be used simultaneously.
  • More Convenience.  All Suburban water heaters are designed for easy installation, operation and maintenance. The limit switch, reset button are conveniently located in a housing behind the removable outer door. The electric heat element and combination drain plug/anode rod are also located there.
