Dual heat pump on 19 Berkshire

Do you need the additional heat pump that they offer on the 19 models or does a single heat pump do fine?

I don't know what size your Berk is but in a 32' M/H it's big enough to take the chill off, and I don't think my ceiling is as high as yours. It has it's purpose and I don't think it's for pure heating, yes I would say 2. It's not much more money then a straight AC

They would not install one heat pump and one not a heat pump. A heat pump system is one A/C compressor with a reversing valve to move the gas in the opposite direction.

They do not produce heat with lower than 32 degrees out side air temp.

Whether or not you need two depends on your comfort level for A/C and Heat and where and when you camp.

I think he just said they did, not uncommon. With mine past 40 degrees you going to want to turn the furnace on.

While this may be technically true for most heat pumps, donít they really become ineffecctive at more like 42 degrees? Iím pretty sure you and others have said this. I donít own a heat pump, so I donít know, but I know a lot of people expect a lot more out of heat pumps than they are really capable of.

Iíve got the Ď19 34qs and I thought the same thing. But hereís my take after just getting back from a month-long trip ....

When you turn on the heat pump in the living area, the ceiling vents in the bedroom put out heat. So FR connected them in the ceiling apparently. If the bedroom unit was a heat pump as well, it wouldnít be great because the noise of it would keep you awake most likely. So I actually think itís better the way they made it.

Also, if you want heat, just plug in a small space heater. Our space heater (referenced in another thread), works very well. I woke up one night sweating because I was way too hot. I had the bedroom door closed and the space heater going, and it got tooo warm in there. So needless to say, that setup works very well.

If youíre boondocking, the propane furnace works too. Thereís a vent under the bed from the furnace that is fairly weak, but does put out a little heat. Iím going to make some sort of Mod that will allow me to take the main vent hose from the furnace and direct it to the bedroom area. Because the other problem with boondocking is that if youíre doing it with your slides in, all the vents are blocked for the most part.

The bedroom unit does NOT have a heat option that can be used. And the main living area unit will not come on if itís 42deg or lower.

You are 100% correct!

It's is impossible to say at what temp it doesn't work. It ranges from 40 to 32 on this forum with a few "But mine works down into the 20's". Residential units work down to 32 so that it the number I use. Basically RV heat pumps are just noisy air warmers and I will ever deliberately own one because they have gone to an Air sampling system that makes they cycle on and off or keep the fan on at all times. Furnace works great for me.

All you need is one of these little guys. Close your bedroom door about 75% and enjoy. You wonít be wasting your LP. Plus, like Iíve stated, the furnace only has ONE little vent in the bedroom which is under the bed.

It will work down to 32 degrees, you are absolutely correct, but the delivered temp Is not acceptable without supplemental heat such as a heat strip, same in a residential system.
