Heat vents

We are currently looking to buy a Jayco Greyhawk 31DS. We are wondering if anyone in this forum has a 2016 31DS. Do you have any heating issues? We noticed that there is a vent in the bath and one right by the entry door. Talked to the dealer this morning and he said there is another vent that is in the bedroom right across from the bathroom vanity through the wall. So with the 3 vents in mind do you think it heats ok? We currently have a 34' fiver and it has two floor vents in the living area and one in hallway and one in bath and one more in bedroom. We understand that with slides and not good r value in the slides and cold floors, heating can be difficult. We understand that. We are just trying to get a feel for how the 31DS has for heat circulation. Thanks, Bill

Are you sure there aren't any vents along the bottom of the galley cabinetry or anything like that? Doesn't seem like near enough vents to me.

Thanks for your reply and yes it only has 3 vents. I had called the dealer that we are working with and he verified the vents.
Thanks, Bill

I would look for some youtube videos of that model and see if you can find some vents by paying close attention. Pause often. See if you find any more.

Maybe somebody else with that model will chime in to help you out.

We have an older 31DS, 2011, and have just returned from the cold of Utah, Mesquite, AZ and Las Vegas - where night time temps were down to 32 deg. No problem with the propane heater keeping us warm. Usually turned it up in the morning and the MH warmed up quickly. I haven't counted the vents but however many they kept us warm. I may just count them tomorrow although I think heat output is more dependent on the BTU capability of the heater.

Dont forget that your AC unit is also a heat pump. So if you keep your thermostat on electric heat it will run the heat pump and push heat thru your ceiling vents. If it is very cold the gas furnace will kick on and push heat out the floor vents.

We have a 2015 31DS and we have no problems with the heat. The heat pump doesn't work well if the outside temp goes below 40 degrees. The propane heat works good. We did have a problem with the propane heat defaulting to 72 degrees but Jayco fixed that with an isolation relay. The coldest we have been out has been 28. Good luck

We have a 2013 Greyhawk 31FS - would our A/C have a heat pump? Do they all have one? We have always just used the propane furnace when heading back north.

We have the Redhawk 31xl and have been camping in Tahoe the last few days running our furnace on electric. Our heat just comes out via the floor vents, we have 4. Nothing coming out from the ceiling a/c unit. These seem to be two seperate units.

I read on another forum that 4 vents means the underflooring is not heated. If you have less see if it is the winterized package, if so, the underfloor is heated.

Two ways to check if you have a heat pump. First look at the settings on your thermostat. If you see electric heat, then you have a heat pump. Second way is to go to Jayco site. Look up brochure for your year and model of Greyhawk. I'm sure that heat pump or underfloor heating would be listed if it was included in your MH.

we may be splitting hairs, but I didn't think my 2016 31FK has a "heat pump" - I thought it was more like resistive strip heat (like a big hair dryer). I need to re-read the manual.

IIRC - there are only 3 vents in ours. One in the kitchen, one in the bath "hallway" and one in the master.

It stays warm enough.





Just looked at the manual for our Coleman Mach 8 15000. It's got a heating element.

PConroy,
On about page 139 of the 2016 Greyhawk owners manual the heat pump is mentioned . Do you think it is really not a heat pump? I thought it is, but what do I know?

You probably know a helluva lot more than I do!!!

On our first RV, a 2008 Coachmen, I read the whole 200 page manual and thought - "Wow what a waste of paper!"

Before we grabbed the Greyhawk I downloaded the manual and didn't find it much more specific. So I spent a hour and hit all of the manufacturers websites and downloaded the product specific manuals.

Muuuuuuuuuuch better.

So that's where I picked up the heat strip thing on our Coleman Mach 8 AC unit. That sucker sucks the amps when it's heating! We used it once when temps dropped into the low 50's to take the chill off. But any colder and I go straight to the propane eatin' furnace!

I have a 2017 Greyhawk 29MV, it has three heat vents along the floor (kitchen, bath and bedroom) that blow out when the gas heat is on. THey work great and will get the coach up to 80 degrees easily. I also have electric heat pump that can be turned on separate or while the gas heat is on as well. the electric heat pump blows out the same ceiling vents as the A/C but does not heat as well as the gas heat.
