Heat is certainly not the problem now that it is getting cold

[brandss]

Newbie of course and trying to figure out this heat thing with the coach. We are in a campground with all hookups. The coach has electric heat from the units on top of the coach, heated tile floors with thermostats in the half bath, an electric fireplace in the family room and the aqua hot heating system.

Here is what we face. Temps over night have been in the mid 30's and we have had the tile floor set to 68 degrees, the fireplace off, and the heat set to electric with the 3 thermostats set at 68 degrees. All is good until roughly after lunch and then the coach gets to over 80 degrees. Nothing is running, floors continue to be set at 68, roof top units don't run, fireplace off. The only thing I can think is that the sun from the day has heated to coach but what seems odd is that the outside temp never goes above 70.

Anyone have any thoughts on this? We end up opening a window or two and turning on the fantastic fan and sucking air in from the windows and out the top of the coach to cool it back down.

Kind of normal

I would think it was the sun heating the coach if it is a sunny day and the shades are not down. Like Mr-D said, seems normal

Thanks for the replies. Us newbies always appreciate you kind folks continuing to answer the often asked questions.

The one thing I would be looking at is whether or not the floor heating system is actually making heat when the heat spikes. If it is off I would be looking for an automatic set back feature to turn it off sooner.

If you're in full sun (or any sun, for that matter), that's what's heating up the coach. Just like your car in winter on a sunny day. It can be 15-degrees outside, but if the car is sitting outside in the sun, it'll be toasty warm inside.

Yes perfectly normal. Coach will heat up a lot with sun.
Here is a graph from past 2 days on our coach. Thermostat is on 58, highs in the mid 50’s.

I am certainly not the smartest and once again proved it with this post, lol. The car sitting in the sun is a great analogy and I'm sure thats what it is. Thanks for all the replies.
