Product overview

MRCOOL® Universal Series Electric Heat Kit

Reliable Backup. Instant Warmth. Total Peace of Mind.

Never let a cold snap catch you off guard. The MRCOOL® Universal Air Handler Heat Strip is the essential performance upgrade for your MRCOOL Universal Series system. Designed to provide high-capacity supplemental heating, this kit ensures your home remains a sanctuary of warmth even when the mercury drops well below freezing.

Think of the heat kit as your HVAC system's "safety net." While your heat pump is incredibly efficient, there are moments—during extreme Arctic blasts or a primary system defrost cycle—where you need raw, immediate heating power. This heat kit delivers exactly that.

  • Emergency Reliability: If your primary heat pump ever requires service during a winter storm, the heat strip takes over, acting as a dedicated furnace to prevent your pipes from freezing and your family from shivering.

  • Integrated Safety: Unlike basic heat strips, this includes a built-in circuit breaker. This simplifies installation and provides an extra layer of electrical protection for your home.

  • Plug-and-Play Compatibility: Specifically engineered for the MRCOOL Universal Air Handler, ensuring a perfect fit and seamless communication with your existing thermostat and blower.

  • Instant Heat Delivery: While heat pumps move heat, these strips create it. Functioning like a heavy-duty industrial dryer, the kit uses high-grade heating elements to warm the air directly before it is dispersed through your ductwork.

Supplemental vs. Primary Heating

It is important to remember that while the heat kit is powerful, it is designed for short-duration support.

Pro Tip: Heat kits are "100% efficient" in the sense that they convert all electricity used into heat, but they lack the high SEER/HSPF efficiency of the heat pump. Use them as a backup or for "emergency heat" mode to keep your utility bills optimized while staying cozy.
