Changing heat pump to heat strip

Good to hear. If it works for you, it is the right answer.

There you go! Good resolve. Our Mach 8s had a heat strip option that would come on to preheat while the heat pump was getting up to temp.

I appreciate everyone's input. I use my coach year round and like to do winter camping. This is a 2016 MH with Coleman units on top. One has a heat pump function. This other is a standard AC unit. Many nights it drops below that 40 degree threshold. I hate using space heaters and propane. My Coleman units have an optional heat strip add-on which I am having added as we speak. Fortunately, I am not having to give up the heat pump function on my one unit as I originally thought, and as one poster mentioned, it gives me both options. I personally like the noise of the roof air units to sleep by, so it fulfills the heating issue and the "white noise" matter for sleeping. I may come back at some point and update everyone on whether it was money well spent.

Our Heat Pumps come with Heat Strips already!
It has been some time or I would remember details of adding Heat Strips to Coleman or Carrier Air Conditioners that did not come with them.
The whole idea of a Heat Pump would be defeated if it didn't have Heat Strips too. The Hat Pumps are better than in our o5 coach but still about 50 degrees or maybe 45 thy don't work too well. Our heat pumps at home had heaters in the compressor to keep it thawed and putting out heat somehow. We have two new units and I don't like Energy Efficient at all.
sounds like you have older units and perhaps the best route if you can afford it is to buy new units but not at retail or from CW.Just be sure they ill fit your openings and if you need new thermostats that you have wires for it or can fish new wires to it. We talked with some Folks, and the same subject might have been posted here of sources being found for half what some people pay for Heat Pumps.I don't remember where though.

Hi,

My RV came with a Dometic thermostat. Of course that limited heating to either/or furnace/heat strip. Since I wished to use both, I added an additional thermostat and moved the furnace over to the new one. Now I can leave the furnace set cooler than the original thermostat and the furnace will "pick up the slack" if needed.

It also means I can boost the 25000 btu's from the furnace by an additional ~5000 btu's.

Air mixing is faster, too.

If the OP's question was about replacing a failed roof unit with either of the two models, not sure the heat strip isn't the more practical.

RV Heat Pumps are no Louder than when they are in COOL(AC) mode. IF you have a loud or abnormal noise, you have a problem. ALL a HP does is reverse the flow of coolant. If it makes a noise in HEAT mode, it will make a noise in COLD mode. The REASON, HP's became more popular was the sound of an LP furnace Blower motor and the hotter output temps, a lot of RVer's did not like. Hydronic systems are almost totally silent. The radiator muffin fans barely make a noise. Most CG's your 120 shore power is part of your daily fee. So, use your HP's for free instead of paying for LP on a furnace or Diesel on a Hydronic system. Hydronic also has 120 elements so that would be "free" also. Doug

My heat pumps work fine and I'm familiar with how they work. I suppose If I was honest my issue is why wear out a very expensive component doing what a $15 Walmart heater will do quietly. Running a HP is no different that running the unit on AC (same wear & tear). Surely in your experience you have seen roof units all have a finite life span.

Double post

My Heat Pumps have settings for A/C, Heat Pump and Heat Strips. I do not use the Heat Strip as it is insufficient heat by its self.
