I've been following several posts on adding the Hybrid Heat kit, or a tankless (on-demand) WH, or the Suburban combo LP/Electric. Also the new Suburban Nautilus on-demand LP WH.
We mostly tour and go post to post, so the advantage of hooking up for "electric" hot water supplemented with our on-board LP would be very convenient (she likes long, hot showers), i.e: duration and recovery time.
My question concerning the less expensive "Hybrid Heat kit" (for the Suburban retro-fit) is that it looks to replace the anode tube with a heating element. This seems counterproductive to the intended function of an anode tube...?
Looking for responses from actual installers. My Chinook is a 2001 Concourse with the typical OEM Suburban 6 gallon LP WH.

Funny you should mention that. Apparently others wondered the same thing, and Camco now has available an extra cost replacement adapter with an anode piece attached:

I'll be getting one for my Hybrid install, after I confirm our Suburban uses the 3/4" version. I'm pretty sure it does.

I can't speak to the add-an-element, but I think you're spot on with using electric while hooked up to a post. Even disregarding faster recovery time or etc.it's much more of a hassle to get a propane fill than just to use a bit more power. I would definitely go electric if that were my use case. I don't have one, but have read that some folks with the Suburban/Attwood combo unit even run them both together if desiring super fast re-heat (didn't even know you could do that, but then I heat my water on the stove or in the sun ;) )

I just noticed this mission goal.

It almost cries out for a tankless solution, with its infinite hot water supply when hooked to city water.

Does anyone make a combo LP & electric tankless?

Yep... I've been looking for a tankless "LP/Electric combo" unit. Nothing so far. Maybe the european or Australian manufactures are making them for the "caravan" market (?).

I considered just adding a stand-alone electric tankless unit right at the bathroom water supply line location (inside the rear storage area). It would serve the bathroom only, but then that's the goal. The GFI outlet by the entry door looks like a candidate for a dedicated 110 connection, with a wall switch added.

I like your free thinking, Hoosier. I've installed a few of the plug-in 110V tankless units for under-sink residential use, and in my experience, the performance is not all that great beyond a quick hand washing. I think showering wouldn't be a reality unless a slow trickle is tolerable. For an electric-only tankless unit to really work for showering, I'd want 240V and 30 amps, which is a ton of juice and not realistic for RVs, not to mention the size of the unit. The gas/electric hybrid design would probably be best.

Scott,
My research has been leading me in the same direction as your comment... low performance at 110V.
My current LP WH unit is original to my rig ('01), so I may just upgrade to the Suburban hybrid/combo (SW6DE).

...sorry baby...shorter showers... :twisted:
