What temp do you set your heat to?

We are tailgating this weekend at a lot that requires no generators between midnight and 7A.
With having two good batteries at full charge, would it be safe to assume we will be able to run our heat between those hours at say 68 degrees?

Sorry if this is a mundane question. I have just had to do it before. It will be a windy 30 degrees outside.

If you really have a full charge and they are good batteries, then you should be OK to run your furnace all night. Just set the temperature setting for it to go off every now and then. Start it at a lower temp then raise the temp until your comfortable.

Are your batteries the original 2002 batteries?

You can go to any automotive parts store and buy a battery "specific gravity" tester for a couple of dollars. This is the only way to know for sure if your batteries are fully charged and good.

They are not the originals. They are two marine batteries (don't remember the specs :( ) that are around 2 years old now.

The title of your posting asked what temp people set their heat to. We set ours at 60. The furnace will not run nearly as long at 60 as it will at 68. To answer your other question, any furnace should last all night (8 hours or so). You will definitely need to fully recharge your batteries each day however.

We set our heat pump pr lp furnace at 66-68 @ night. Don't forget to check the water level of your batteries and make sure they are fully charged.

I set mine to zero, heat off, and use a light weight cover over just me.

There is not much square footage in an RV, and heats up rapidly in the morning.

My way, yours may differ.

Depending on the weather, we set the temp at 60 for night time and have not had an issue with the batteries. During the day we set the temp anywhere between 64-68. There have been times when we have camped in the colder times of the year (20-15 degrees) that the generator runs the whole time we are camped.

Sorry, the title was bit deceiving. I also wanted to know what temp you set your systems at because ours seems to cycle on and off to where it is a sweat box and then cold, sweat box and then cold.
This is with the temp set to around 68 degrees.
Lower may be better.

Good point about the temp swing. I would like to hear more on that also. I use an electric add-on and my temps seem to stay pretty consistent. I have heard that using LPG is when the temp swing is very noticeable. I will have to switch over to LPG one day and see if it is true. I just have not had to since I have shore power available all the time.

I set mine for 75 for heat in front and 73 for AC.
Bedroom usually only gets to 73.
I like to be comfortable.

About a hour before generator cut off time. Get heat up to 82-85 then move thermostat down to your 68 after generator shut off.

Since marine batteries aren't usually true deep cell.
At 7AM use the Aux button to get the generator started.

Most thermostats have an adjustment called the 'anticipator' inside so that you can adjust how big a spread there is between the on & off points.

Mine was like you describe, you'd freeze, then roast, then freeze, when I first bought my m/h. I adjusted the thermostat 2 or 3 times till it got to where if it was set at 60 it came on at 58 and went off at 61 or so.

The anticipator is usually a metal contact strip resting against a coiled wire that typically has numbers such as 1.0, .7, .6, and so on. Normally it's set by the factory to 1.0, but that allows for the widest temperature-cycle swing.

Try changing the calibration more towards a setting of around .5 or .7 and it will slow or solve the yo-yo in temperature.
