Suburban RV Hot Water Service_3

The ACCC is urging consumers who have a dual fuel Suburban gas/electric water heater system in their caravan, motor home, or horse campers to check to see if the unit is part of the recall ahead of any post-lockdown holidays.


If your caravan, motorhome or horse camper was manufactured between May 2018 and September 2019 and you have a Suburban gas/electric hot water system fitted, you MUST read this now.

The ACCC is concerned that more than 50 percent of these units might emit deadly odourless carbon monoxide if used in gas mode. Carbon monoxide poisoning can cause death, and short-term exposure can cause serious long-term injuries.

There are still over 8,300 consumers who have not registered their water heaters for a free inspection. As the risk of failure is so high, the ACCC is concerned that these owners are not aware of the recall and may use their caravan, motor home, or horse campers these holidays without checking if they are safe.

“Consumers should not use the affected water heaters in gas mode under any circumstances, even if they have a carbon monoxide detector,” ACCC Deputy Chair Delia Rickard said.

“It’s very important to check your recreational vehicle, horse camper, or caravan’s water heater as soon as possible as there is a significant risk of injury or death from this product.”

Carbon monoxide is invisible, has no smell, is lethal, and cannot be detected. It is also highly flammable and can explode upon contact with a spark or flame.

The Suburban gas/electric water heaters were supplied between 1 May 2018 and 25 September 2019, either new with the vehicle by retailers nationally, or purchased separately online and installed later.

Consumers can check if their heater is affected by opening the exterior access door to the hot water service and checking the model and serial number located on the right-hand side. They should then enter the serial number on the Coast to Coast website (link is external).

If you have an affected water heater, urgently contact Coast to Coast Caravan and Leisure on 02 9645 7685 or email who will arrange for a licensed gas fitter to inspect it free of charge. Every unit must be inspected.

Consumers will not have to cover any costs related to the supply and installation of the new water heater.

Consumers who have difficulties obtaining a timely remedy should contact Coast to Coast Caravan and Leisure, their state or territory gas regulator or complete an ACCC online report.
