12v Tank Heaters

**HDRider** · January 6

Can someone tell me where the 12v tank heaters are discussed in the manuals? I can't find it.

Thanks

I wasn't aware the 2023 models have them. Do they? Our 2022 doesn't.

As far as I know -

there was only one Oliver ever produced that came from the factory with dedicated tank heaters. This was way back in the custom order days (even prior to my hull #117) and was for an Ollie that was to be used during the winter in northern PA and similar locations.

Other than that, the tanks are located between the hulls of the Oliver and are "heated" by the radiant heat mainly coming off the hoses that come from the furnace to the various outlets located in the interior of the Oliver - i.e. these flexible hoses are not insulated and therefore give off heat in the area between the hulls.

Hope this helps!

My LEII hull#1386 doesn’t have tank heaters! Pretty sure only some older Ollies have tank heaters, back in the day when Oliver still entertained modification request from owners.

I guess that explains why I can't find them in the manuals.

I thought the Ollie had tank heaters

Yep - that 'splains" it.😇

Being that Olivers are ‘four season’ RVs, guess the thought was that tank heaters weren’t really necessary! However, some owners ‘beg to differ’ and addressed their concerns to enhance heat in the hatch areas by various means; more-so to protect waterlines, but the tanks would benefit, as well. The most innovative approach I’ve seen was modification of the existing ducting, whereby holes and/or duct diversions are strategically placed to direct furnace heat, as necessary, to more vulnerable areas. Here are a few pics ‘borrowed’ from a forum post, full credit to that individual. Do a forum ‘Search’ on the matter.
