Coleman Mach 8 Electric Heat Kit 120V | 37203-4551
Coleman Mach 8 Electric Heat Kit 120V | 37203-4551 — Product description
This is the electric heat kit that turns a heat-ready Coleman Mach 8 rooftop air conditioner into a heat-and-cool unit. It's a 120-volt strip rated at 5600 BTU, built to drop into Mach 8 heat-ready ceiling assemblies and Coleman AC models beginning with 3. If your ceiling assembly came heat-ready, this is the piece that finishes the job.
If you bought a heat-ready Coleman Mach 8 ceiling assembly, you already know it doesn't heat on its own. It's built to accept an electric heat kit, and this is that kit. Drop it in, wire it to 120 volts, and your rooftop air conditioner does double duty on those chilly mornings at the campground.
The kit puts out 5600 BTU of electric heat. That's enough to take the edge off a cold RV interior without firing up the propane furnace. A lot of owners run the heat strip first thing in the morning to warm the coach, then switch to furnace heat only when the temperature really drops. It's quieter than the furnace and it doesn't burn propane, so you're not chasing down a fill on a cold weekend.
Fitment matters here. This kit is made for the Coleman Mach 8 heat-ready ceiling assembly and for Coleman air conditioner models with a part number beginning with 3. If your Mach 8 assembly wasn't ordered heat-ready, it may not have the space or wiring provisions for the strip, so check your assembly before you order. When in doubt, give us the model number off your ceiling assembly and we'll confirm the fit.
Installation is straightforward for anyone comfortable working around 120-volt AC wiring in an RV. The strip mounts inside the ceiling assembly and ties into the unit's control. If you're not confident with line-voltage work, have an RV tech handle it. It's not a big job, but it is line voltage, so treat it with respect.
One honest note. This is supplemental heat, not a replacement for your furnace in deep cold. Electric heat strips like this one shine in the 40 to 60 degree range where you want to knock the chill down fast. Below that, your propane furnace is still the workhorse. Run them together on the coldest nights and you'll stay comfortable.

Frequently asked questions
Will this work with any Coleman Mach 8?
It's made for the heat-ready version of the Mach 8 ceiling assembly and for Coleman AC models whose part number begins with 3. If your assembly wasn't ordered heat-ready, it may not have the provisions for the strip. Check your ceiling assembly model before ordering.
How much heat does it put out?
5600 BTU. That's supplemental heat, enough to warm a coach in the 40 to 60 degree range. For deep cold you'll still want your propane furnace.
What voltage does it need?
120 volts. It runs off shore power or your generator, not the 12-volt house battery.
Does this replace my furnace?
No. Think of it as a fast, quiet way to knock the chill off without burning propane. On the coldest nights you'll run it alongside the furnace.
Is it hard to install?
It mounts inside the ceiling assembly and ties into the unit's control. Anyone comfortable with 120-volt AC wiring can handle it. If line voltage isn't your thing, have an RV tech do it.
How do I know if my assembly is heat-ready?
Heat-ready assemblies are built with the space and wiring provisions for this strip. If you're not sure, send us the model number off your ceiling assembly and we'll confirm before you buy.
