R&R Hot Water Heater

[Eric Johnson]

Hi Harold,
Don't know what your coach bed configuration is but ours has a side bath with
twin beds
in the back. I replaced ours old unit with an Atwood heater and learned the
following:

1. Atwood heater is slightly taller than original heater and I had to raise the
drivers side
bed about 1 inch. Used sections of square aluminum tube stock around the
perimeter of
the bed to make the change.

2. Atwood heater has a high temperature switch that trips at 185 ºF so
circulating jacket
water through it in the summertime can cause it to shut down when the coach
engine is
working hard. Resetting the switch is a pain so I shut off the water
circulation from the
engine in the summer and let the generator do the work.

3. Space is very cramped under the bunk with lots of sheet metal screws, etc to
cut your
hands while working on the piping.

4. I used PEX piping and fittings to pipe up the heater.

5. Total job took 8-12 hours for a first timer.

Not my favorite job but great feeling of accomplishment when it's done!
