It runs on 120V shore power and takes the morning chill off without burning propane. Fits low-profile 35xxx and 45xxx and medium-profile 38xxx and 48xxx assemblies, not Mach 8.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eCool mornings in the RV don't have to mean firing up the propane furnace. This Coleman electric heat kit adds 5,600 BTU of warmth straight through the rooftop AC you already own, as long as that unit is running a heat-ready ceiling assembly. It's the simple way to take the chill off before the sun comes up.\u003c\/p\u003e\n\u003cp\u003eHere's how it works. Coleman builds certain Mach ceiling assemblies as heat-ready, meaning they're wired and sized to accept an electric heat element. This kit is that element. It drops into the assembly, runs on 120V shore power, and turns your air conditioner into a heat-and-cool unit. No separate heater to mount, no extra ductwork, no propane burned.\u003c\/p\u003e\n\u003cp\u003eFitment matters, so check your assembly before ordering. This kit is made for the low-profile 35xxx and 45xxx series and the medium-profile 38xxx and 48xxx series. It does not fit Mach 8 units. If your ceiling assembly isn't the heat-ready version, the kit won't have the wiring it needs, so confirm that first.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone who camps in shoulder season, spring and fall, when the nights dip but you're plugged into shore power at the site. Electric heat off the rooftop unit is quiet, even, and it doesn't touch your propane supply. That's a real advantage when you're trying to stretch a tank or you just don't want the furnace cycling all night.\u003c\/p\u003e\n\u003cp\u003eA word of honesty. This is supplemental electric heat, not a furnace replacement. In mild cold it does a great job warming the cabin. When temperatures drop hard below freezing, you'll still want your propane furnace for the heavy lifting. Think of this as the every-morning comfort layer, the thing you reach for far more often than the furnace.\u003c\/p\u003e\n\u003cp\u003eIt's a genuine Coleman part, MPN 38203-4551, built to match the ceiling assembly it installs in. If you're comfortable working around your rooftop unit's wiring, it's a straightforward add. If you're not, any RV tech will have it in and running in short order.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e5,600 BTU electric heat output takes the chill off cool mornings without firing up the propane furnace\u003c\/li\u003e\n  \u003cli\u003eRuns on 120V shore power, so it heats while you're plugged in at the campsite\u003c\/li\u003e\n  \u003cli\u003eDrops into Coleman Mach heat-ready ceiling assemblies, low profile (35xxx \/ 45xxx) and medium profile (38xxx \/ 48xxx)\u003c\/li\u003e\n  \u003cli\u003eTurns your existing rooftop AC into a heat-and-cool unit, no separate heater to mount\u003c\/li\u003e\n  \u003cli\u003eGenuine Coleman part, MPN 38203-4551, built to match the ceiling assembly it installs in\u003c\/li\u003e\n  \u003cli\u003eNot compatible with Mach 8 units, so confirm your assembly before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Coleman reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does this heat kit do?\u003c\/summary\u003e\n    \u003cp\u003eIt adds 5,600 BTU of electric heat to a Coleman Mach heat-ready ceiling assembly, turning your rooftop air conditioner into a heat-and-cool unit that runs on 120V shore power.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWill it work with any Coleman Mach air conditioner?\u003c\/summary\u003e\n    \u003cp\u003eNo. It fits heat-ready ceiling assemblies in the low-profile 35xxx and 45xxx series and the medium-profile 38xxx and 48xxx series.
