MRCOOL 5kW Heat Kit with Circuit Breaker for TruInverter Air Handlers

The MRCOOL 5kW Heat Kit (MCAEHFD5X1BA) is designed to provide supplemental and emergency heating for MRCOOL Signature Series TruInverter air handlers. Installed directly inside the air handler, this electric heat strip ensures your system can continue delivering heat even when outdoor conditions push your heat pump beyond its limits.

While heat pumps are highly efficient for everyday heating, extreme cold temperatures or system interruptions can reduce performance. This heat kit acts as a reliable backup, delivering direct electric heat through your ductwork when you need it most.

Key Features

  • 5kW electric heat strip for supplemental and emergency heating
  • Built-in circuit breaker for added protection and simplified installation
  • Designed for MRCOOL Signature Series TruInverter systems
  • Installs directly inside compatible air handlers
  • Provides reliable backup heat during extreme cold conditions
  • Automatic operation when auxiliary heat is needed

Compatibility

This heat kit is compatible with the following MRCOOL Signature Series TruInverter air handlers:

  • 24K BTU Systems
  • 36K BTU Systems
  • 48K BTU Systems
  • 60K BTU Systems

What Does a Heat Kit Do?

A heat kit functions as a supplemental heating source inside your HVAC system. When outdoor temperatures drop too low for efficient heat pump operation, or if the heat pump is temporarily unavailable, the heat kit activates to provide direct electric heat.

Often compared to a high-capacity heating element, it warms air as it passes through the air handler and distributes it throughout your home via ductwork.

When Is a Heat Kit Used?

  • During extreme cold weather when heat pump efficiency decreases
  • As emergency heat if the outdoor unit is not operating
  • As supplemental heat to maintain indoor comfort

While heat kits are not as energy-efficient as heat pumps, they are an essential component for maintaining reliable comfort in colder climates and high-demand situations.

Installation Notes

This heat kit is designed for installation inside compatible MRCOOL air handlers. Professional installation is recommended to ensure proper electrical connections and system integration.

Why Add a Heat Kit?

If you want peace of mind during extreme weather conditions, the MRCOOL 5kW heat kit provides a dependable backup heating solution. It ensures your system can continue delivering warmth when your heat pump needs support or during unexpected outages.

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.

Good quality pillows overall
Size: King (Pack of 2), Color: White
Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed. First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification. Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material. Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.

Hallelujah… finally, I found the right pillow!!!
Size: Queen (Pack of 1), Color: White
I have spent a lot of money searching for the right pillow. I recently tried to Tempur-pedic that cost twice with this pillow cost. Tempur-pedic flattened out. I’ve had this pill for a few weeks now and it works wonders. I am a paraplegic. You can have a lot of neck problems. I love the fact that this pillow is adjustable. I immediately saw it was too stuffy and took a bunch out. It works perfect so glad I didn’t spend money on a $200 purple pillow. I read a lot of reviews and there were a lot of complaints about the odor. Mine did smell funny when it came out of the box. I immediately threw it in the dryer with a few bounce fabric sheets came out smelling fine. Pillows are a very individual thing, but I think for 40 bucks this pillow is worth a try. I’m really enjoying mine about one of those silk pillowcases to go over it and it sleeps cool and comfortable. Best wishes in your search for the right pillow. Update: I’ve been using this pillow several months and it continues. Give me a good night rest pain-free.. well worth the money. UPDATE: I have been using this pillow for three months and it still works great. It does not flat out or get hot..
