Knob Creek? Nice! You might also want to give Woodford Reserve (or even better Woodford Double Oak) a try as see if you ever look back!

To stay on topic, our current 98 CC has NO electric heat. Our ’88 did and I find it hard to believe that CC took out this valuable option. Until we need to keep the bays warm we have added portable electric heater to keep the chill off here in TX with primary heat from the Webasto. We are in a park where we have to pay for electric so it seems the best value is the Webasto.

I understand the logic of running electric heat when you aren’t directly paying by the KWH, that makes the most sense; like Bill said fire is the best choice when it’s your $; As Jon mentioned, propane is even better, however you don’t find that in a modern Prevost; Any rough ideas of the diesel consumption of AH & Webasto?

Aqua Hot has a 2010 Webasto burner .5 gallons per hour, but that’s when burner is running pretty easy on fuel, Where Propane is very explosive much more then diesel, and those Atwood and Suburban propane furnaces suck the propane. I’m a Aqua Hot tech so I’m partial to Aqua Hot’s

[Bill]

The Webasto 2020 uses a .38/gallon nozzle and runs less than 1/2 the hour once the coach is up to temp (depending upon HOW cold it is outside). Worst case, it runs no stop and it costs about $1.50/hour to run.

Back in the olden days most Prevost conversions had propane. The early conversions were using Norcold or Dometic 3 way refrigerators, and since propane was a very cheap way to keep them cool the propane was also used for furnaces like the Suburban units.

When coaches started using house type refrigerators the use of propane ended.

Bill,

Don’t you have floor heat in your coach? That was pretty much standard in their upscale production coaches from around 2000.

[Marshall]

No, there is no electric heat in this coach at all. I didn’t look at that when I made the purchase but it would not have been a deal breaker in any case. In our ’88 there was only electric baseboard in the bedroom as a previous remodel had removed the living area heater.

We like the electric option as a money saver since where we usually park the electric is free and we don’t have to use as much diesel with the Webasto.

To correct myself, there are no toe kick style electric heaters. We do have 3 roof airs. 2 are heat pumps and one has an electric strip heater so at least that one would provide electric heat to the living room and kitchen areas during the colder days when the heat pumps will not work. Heat (that rises) is just not as practical as floor heat but I might try the air dump option to blow the heat straight down instead of through the ducts.

Fulltime Bill: Consider in-floor electric heat if you ever decide to replace the flooring. We have it in parts of our house, really like it. Long-term, if we ever replace any of the floor in the coach, it will have electric heat under it if possible.

Update on performance of the Cruise-Airs:

Dec 24 @ 11am: OTA = 19*F, H2O Bay = 60*F, Galley C/A Outlet = 72*F, Stateroom C/A Outlet = 76*F

Dec 24 @ 10pm: OTA = 9*F, H2O Bay = 45*F, Galley C/A Outlet = 70*F, Stateroom C/A Outlet = 74*F

Dec 25 @ 10am: OTA = 18*F, H20 Bay = 48*F, Galley C/A Outlet = 72*F, Stateroom C/A Outlet = 75*F

Only Galley and Stateroom C/A’s on, both C/A’s set at 55*F (apparently lowest temp the SMX will me/us go), C/A’s indicate a temp of 53/52*F (I assume at the point of inlet air), one 1000 watt cube heater with fan on floor in the galley and another on floor at door between bath and stateroom, thermometer on galley counter against outside wall 64*F. I have an AcuRite wall thermometer with digital readout that supports three remote thermometers; one behind the front bumper, one in the water bay, and one in the stateroom. It sits on the galley counter. I stuck a digital meat thermometer in the outlets of the C/As

Now that I’ve tracked and recorded this information, I’m questioning why I have the cube heaters on. Its supposed to warm up and I’ll turn them off this afternoon.

My original post that I began this thread with was also posted to one of the Prevost Facebook pages; probably Prevost Community. Someone responded who is an expert on refrigeration and heat pumps. He said that a heat pump can pull “heat” out of any temp air, it just might not feel warm to us. That statement now makes sense to me after logging the temps.
