Sportscraft Posted October 8, 2010 Share Posted October 8, 2010 I believe its an electric element somewhere that heats up quicker therefore helping you get warm air faster. Beyond that not sure of the rest of the technical details. I have it on my truck, but haven't had cold weather yet. Quote Link to comment Share on other sites More sharing options...
Painted Horse Posted October 12, 2010 Share Posted October 12, 2010 It is an electrical element that basicay automatically turns on if the heater controls ask for heat and the engine cooling system has not reached 180* It stays on until the engine coolant reaches 180* and turns off automatically when tthe coolant is warm enough to run the heater/defront on its own.

theoldwizard Posted October 12, 2010 Share Posted October 12, 2010 Interesting because "modern" cooling systems are designed to get the coolant up to "operating temperature" as fast as possible, Better for emissions. Quote Link to comment Share on other sites More sharing options...
Sportscraft Posted October 13, 2010 Share Posted October 13, 2010 SO I've noticed that with the remote start the engine starts but the heater does not come on untill you put in the key. I realize that it still helps it heat faster (having the engine heated up) but still feel like this defeats the purpose of remote start! Its still going to be cold and my windows are still going to be iced up. Is there a setting somewhere to change this? Quote Link to comment Share on other sites More sharing options...
Painted Horse Posted October 14, 2010 Share Posted October 14, 2010 I have not tried it yet. Since I park in my garage, and it hasn't really gotten cold yet. But I understand it should Heat or Cool the truck based upon what controls you left on when you turned off the truck and how those settings compare to the outside air temps. i.e. if the climate control is set for 74* and it's in Auto, and the outside temps are 34*. The rapid heat should turn on and be blowing 74* air until the engine coolant reaches the 185* temp and the supplemental heater turns off.

2011screw Posted October 29, 2010 Share Posted October 29, 2010 i need some information on this Get it. I would never get another diesel without it. Well worth the money 1 Quote Link to comment Share on other sites More sharing options...
Sportscraft Posted October 29, 2010 Share Posted October 29, 2010 (edited) I noticed it did seem like the heat was on the other day. I think basically the controls (dash) don't light up when the key is not in the ignition even though the remote start and heater is running.

Stng1996 Posted October 29, 2010 Share Posted October 29, 2010 Interesting because "modern" cooling systems are designed to get the coolant up to "operating temperature" as fast as possible, Better for emissions. True for gasoline powered vehicles, but not for compression-ignition engines. Quote Link to comment Share on other sites More sharing options...
Stng1996 Posted October 29, 2010 Share Posted October 29, 2010 The Rapid-Heat supplemental cab heater, an available supplemental heating element on diesel Ford trucks only. The electronic heater assembly contains the Auxiliary Heater Control Module (AHCM) and element, and is located in the HVAC immediately downstream of the heater core.

Optikmike Posted March 15, 2011 Share Posted March 15, 2011 I've read elsewhere that these new 2011 diesels don't heat up quickly in cold temps and may not heat up at all while idling so I opted for one on my truck even though I live in the south.

lkbrow1 Posted March 15, 2011 Share Posted March 15, 2011 I have an 18 mile drive to work and the temperature gauge doesn't start moving until I am half way to work in my 2005 F350XLT Crew cab. So I sprang for the Remote Start and the Axillary Heat in my new truck that I ordered in the end of January. It will be Spring before I get it so I will have to wait until next year to test. Having the Engine block heater plugged in does help. Quote Link to comment Share on other sites More sharing options...

Having the Engine block heater plugged in does help. I did the same when I ordered my new 2012. My 06' would heat up just as I pulled in to the parking lot at work. Not to mention it is a safety issue if the windows are foggy. Quote Link to comment Share on other sites More sharing options...
bearqst Posted November 26, 2011 Share Posted November 26, 2011 (edited) For those of us that didn't order the Rapid-Heat supplemental cab heater (2011 F250, 6.7), any suggestion on the best alternative ? I have the dealer looking into it, but their at a loss and so far I can't get a straight answer into having it install after the fact. I have a 15 mile drive to work and at anything below -15 below (f) (at least since I put the grill inserts in) I'm wearing my arctic parka, not the best way to get to work.

DozerUSMVMC Posted March 8, 2013 Share Posted March 8, 2013 You can start your truck with the heat blowing. All you have to do is go into your truck settings on your dash readout and turn on "last setting" under the remote start. What this does is when you remote start it turns on the heat to the temp of when it was shut off and the fan speed (this will not turn on the heated seats or steering wheel) but with the new trucks like on the one I ordered if it is below 40 degrees the seats and steering wheel turn on as soon as you remote start Quote Link to comment Share on other sites More sharing options...
wgunkel Posted April 26, 2014 Share Posted April 26, 2014 You want the Supplemental Heater the diesel heats up slower than gas and without it you be blowing cool air for a while I live on the cost in Calif we had few days were weather was just above or at freezing and have the Supplemental Heater in my 2008 SD warmed thigs up quickly. Heated seats help too By the way the Supplemental Heater requires dual Alternators beasue of the high current draw Quote Link to comment Share on other sites More sharing options...
asphaltman Posted April 27, 2014 Share Posted April 27, 2014 Not totally true on the alternators, the extra heavy duty one is also an option for Rapid Heat. In my experience though, rapid heat was barely noticeable. Quote Link to comment Share on other sites More sharing options...
Clean-15 Posted May 21, 2014 Share Posted May 21, 2014 SO I've noticed that with the remote start the engine starts but the heater does not come on untill you put in the key. I realize that it still helps it heat faster (having the engine heated up) but still feel like this defeats the purpose of remote start! Its still going to be cold and my windows are still going to be iced up. Is there a setting somewhere to change this? Have you verified that this is the way its supposed to work? I'm hoping not :o( Just ordered a 2015 and did select this option but hopefully it works when remote started. Quote Link to comment Share on other sites More sharing options...
Painted Horse Posted May 22, 2014 Share Posted May 22, 2014 I frequently remote start my truck and when I come out 5 minutes later my windshield is almost defrosted from the Rapid Heat 1 Quote Link to comment Share on other sites More sharing options...
Clean-15 Posted May 31, 2014 Share Posted May 31, 2014 It would be cool to see a side-by-side compare of two trucks iced over. One with and one w/o the rapid heat option! 1 Quote Link to comment Share on other sites More sharing options...
Larry1013 Posted June 5, 2014 Share Posted June 5, 2014 The rapid heat is suppose to come on with the remote start if they temp calls for it... Quote Link to comment Share on other sites More sharing options...
riley49 Posted August 18, 2014 Share Posted August 18, 2014 It would be cool to see a side-by-side compare of two trucks iced over. One with and one w/o the rapid heat option! I agree. I would like to see a comparison. Whe I ordered my 2011 F350 i got the rapid heat option and the dealer here in NM said he didn't think I would ever use it, but I like that pretty quickly after I start I can have warm air in the few days that it is actually cold.

15F4fiddy Posted September 14, 2014 Share Posted September 14, 2014 We are happy that we did opt in to add this feature to our new truck. Sounds like an option you really don't want to do without. Thanks :-) Quote Link to comment Share on other sites More sharing options...

And I don't understand why when using remote start, you can't set it so that your seat heating can begin then too. Quote Link to comment Share on other sites More sharing options...
Ford truck guy Posted March 13, 2015 Share Posted March 13, 2015 I can honestly say that we had a pretty cold winner here in PA... I made a mistake and did not order the rapid - heat.. I do snow plow with it ,so I am out a lot ... I did not miss it one bit ?? Was I getting used to the cold , doubt it.. I'm not getting any younger... I was really worried that I would need it......
