Since getting our Winnebago EKKO, we’ve really enjoyed the instant hot water provided by our Truma AquaGo.  It’s tankless, and since the water heats up so quickly, we’re actually washing dishes with hot water these days.  It’s a luxury we didn’t know we were missing!

Anyway, now that the weather is turning colder, we need to think about keeping our AquaGo from freezing.  Truma makes a special accessory to help here: The Electric Antifreeze Kit.  When I was researching it, there seemed to be a lot of confusion about what it did and when to use it.  Our friends at Truma sent us one to try out, so we decided to make this video to set the record straight and let you know when WE plan to use it.


Hopefully, the video explains most everything you need to know.  But there were a couple points I want to call out again, just to be crystal clear.

  • The Electric Antifreeze Kit is only available for the Truma AquaGo.  It doesn’t work with the Truma Combi, or any other brand RV water heater.  To my knowledge, Truma is the only company offering such a device for their tankless heaters.  There is no similar option out there to compare it to.
  • Although I drained the water heater before the video, you can see that some water was still left in it.  This is probably because the RV was not level when I drained it.  To be thorough, after draining the AquaGo, Truma recommends leaving the filter cartridge out to ensure all water is drained. The filter can be stored by the control board above the gas line or inside the RV.
  • I did this correctly in the video, but just to reiterate – you should use a hand tool (rather than a power tool) when tightening the screws holding the bracket.  This will help prevent over-tightening them, which could cause damage to the door.


Since we like winter RVing, and we like hot showers… we’ll use the antifreeze kit as part of our winter travel routine.  I anticipate the hardest thing to do will be to force myself to go outside and remove and install the flue plug when it’s cold, but maybe I can convince Stef to do that part (… NOT!).  We have a big winter trip coming up, so we’ll see how it does on the road here in the next few weeks.

Do you have the Truma Electric Antifreeze Kit?  If so, how do you use it?  Sound off in the comments below.
