I noticed that when I turned on that switch in the bathroom with ambient temp about 45, my amps used were unchanged..Is that switch inoperable because I have Hydrohot with a bay heater control in the sewer bay??? Or does the temp need to be colder before it will work?

Most tank heat pads I've seen have an internal "thermostat" set at around 35 degrees. Thus internally preventing heating until then even when "turned on" by the power switch. Try again on a colder night and you should see an amp increase.

Larry, I believe the switch in the bathroom marked "Heater" is for arming an automatic fan for the Hydro Hot system. The Hydro Hot has to be hot and the thermostat for that zone having a higher set temp than the actual will cause the fan to operate.

Quick Tip: After camping in a cooler area, leave all thermostats at there current settings when you leave camp. Do turn off both the electrical element and diesel heater switches. You will find that the heat maintains somewhat all day as the engine will maintain the Hydro Hots temperature. So when you go back to use the bathroom while travelling, the fan with warm air will probably greet you.

I believe our two coaches have a lot in common, i.e. '07 DSDP vs. 06 MA

If the switch in the bathroom (above sink next to shower) is the same as mine it says heat pads. I presume it's there b/c of proximity to tanks and was an easy install.

Hi Nut...
my switch is marked "tank heater pads" with the emphasis on PADS. I had the switch off, hydrohot was on and went below and found my bay heater fan on...the temp was set to about 45 degrees and was less outside..and this is ON the Gulf of Mexico...I pity all the Nawtherners stuck up Nawth !!
Btw, I checked out the operation of the Hydrohot on the way home....had my 4 sugargliders on the bed and set the rear heat to 72..had the front heat off and the window open...when I got home, my little babies were nice and warm...plenty of hot air still in the system after a 2 hour trip!
