Is wet bay heater working?

I have my AH on diesel and electric. We are camping where overnight lows are in the teens. I turned my rheostat up in the wet bay to about the 2 o’clock position. I feel a click just before that, but otherwise there is no indication that the bay heater is on or working except that nothing has frozen so far. I’m using a heated water hose and also have my floor heaters on, but I’d like to have a better idea that this thing is actually working. Thank you.

The only way to know for sure is to put a remote thermometer in the wet bay. Keep in mind that some warmth from your heated floors will make its way into the basement.

Recently placed a 40 watt flourescent clamp-on in my View's wet-bay. The light shines through the plastic box into the wheel well. Cool!

Don’t know what the 2 o clock position represents, but I would turn it all the way up and see if the fan comes on a d hear comes out.

On our rheostat, right in the middle of the range is the 45° point. Just put a thermometer down there, and check it just before you go to bed.

Get one of those high/low, min/max thermometer, the ones I have seen, have a U shaped tube, with magnets, it records the highest and lowest temperature. Keep a log and go from there

Look for the “40” degree setting on the dial. You should set it there.

OP, I have a 2021 Bus, my wet bay heating system was partially installed, only pertinent to this post because I had to confirm my wet bay heater worked after I finished installing the missing equipment.

Turn on the Diesel heat for the AquaHot, submerse the copper bulb from the rheostat control in the wet bay into a glass of ice water and crank the rheostat knob fully clockwise. This will kick on the wet bay heater. The very top of the wet bay facia panel should start getting warm. The cozy heater is just behind the panel. You can put your palm on this area and start feeling the warmth. If you have an IR gun to measure this area it will be quite definitive as to whether your wet bay heater is working. You should see a 2-4 degree temperature rise per minute. I don’t have my IR gun with me and using the palm method was not definitive enough. I needed to 100% verify the wet bay heating function. To do this I moved my wet bay temperature sensor up behind the wet bay facia panel, it was down near the floor next to the water pump. I cut the tie wrap holding the sensor, removed my tank level monitor panel (4 screws), fished the sensor up the back side of the panel to the hole for the tank level panel, tie wrapped the sensor to one of the wires going to the backside of the tank level panel, then reinstalled the tank level panel. The thermistor is now hanging in the air near the plumbing and water tanks behind the panel. Turn on the AquaHot, keep the wet bay rheostat cranked fully clockwise while the bulb is still in the ice water. Look at the wet bay temperature on the Spyder control panel and you should see it rising rather quickly (3-4 degrees per minute). A bit complicated but it absolutely verified the wet bay heater is working, and now the wet bay temperature sensor is in a place that actually reads the temperature of the wet bay in the area that is important. If I’d had an IR gun with me I would not have gone through all of this (except moving the temperature sensor location).
