Question:

Do you sell a ten gallon rv water heater with engine assist? The one we have in our motor home has coolent hoses from the engine that heats water as we travel but it leaks and needs to be replaced but I can not seem to find a direct replacement. Thanks

Douglas, we don't have any 10 gallon tanks with engine assist, unfortunately. We do have the Dometic RV Water Heater # DMC74FR, which is a 6 gallon tank and has a 10,000 btu heating capacity.

Hey Douglas, were you able to find a replacement water heater with the engine assist feature for your motor home? Knowing what worked could help others looking for the same setup.

@JohnH No I did not find any water heaters with engine assist. I think this is something that is no longer offered. Turns out the water leaking from under the heater was not from the heater but from the shower drain. Doug

@DouglasC That is great news Douglas, much easier to fix that leak than to replace your entire water heater. Glad you got things figured out! I hope you have a wonderful Holiday Season filled with your most favorite people =)
