Heated Holding Tanks LY-30

[jbwsc]

The equipment list indicates my 2005 LY-30 has heated holding tanks as standard equipment. I can find no switch or mention in the manual of how they are operated. Can anyone shed some light on this?

Some time ago I posted a question to the effect, "Does anyone know how the holding tanks on a LY30 are heated"? No one was really interested as I received no replies, but for whatever it is worth I found out from an Airstream factory rep I met in Tampa, FL. they are heated by ducted hot air from the furnace. jbwsc

That is right, which means that they aren't heated unless the furnace is running. Ducts should heat the fresh water tank compartment as well as the holding tank area.

This is an older thread from 2007 but had an update to the comments especially for those who own diesel pushers.

The 97 LY diesel pusher holding tanks are heated by the furnace as discussed above. However, the fresh water take is mounted outside in mid frame vs inside under the bed. This winter the lower half of my fresh water tank froze in Montana and it took 3 days to thaw out. The tank itself is not insulated anymore than the gas tank which is mounted ahead of it. I plan to experiment with spray foam insulation on all bottom areas this spring. Not only did the floor get cold in the front section this winter, but while in Florida last summer, I had excessive heat from the road and engine in the rear areas. Also plan to add more insulation around the engine compartment under the bed.
