## Overview

The Supplying Demand HKSC15XB is a 15 kW, 240V electric heater kit designed to seamlessly integrate with your HVAC air handler. Featuring rust-resistant nickel chromium elements, built-in overcurrent and temperature limit protections, and a plug-in wiring harness, it ensures safe, efficient heating with easy installation. Controlled by sequencers for optimal temperature balance, this kit includes all necessary breakers and wiring components, making it the professional’s choice for winter-ready climate control.

## Description

This 240-volt heater coil can be added to an air handler to provide winter-time heating capabilities. Controlled by sequencers for optimum temperature balance. Completely assembled and d. Built-in overcurrent protection on all units as indicated in the electrical data chart. Multiple branch circuit capability. High-temperature limit controls for safe operation. Plug-in wiring harness for easy installation into air handlers. Rust-resistant nickel chromium heat elements. If you are installing a heater coil in an air handler, the line voltage is to be connected directly to the heater coil which will operate both the heater coil and air handler. A separate circuit for the air handler is not needed. Depending on the heater coil size being installed, one or two circuits to the heater coil will be necessary. At your home's circuit panel, individual 220-volt double-pole circuit breakers are required for each circuit.

Review: Fit perfect and worked as expected.
Review: Very happy with the product so far. Definitely would recommend professional installation since it is dealing with electricity but that being said this thing is very easy to install. In my case the heating unit was in the attic, in a tight spot with zero room, which made it a difficult job just because you practically had to hang upside down to access it lol but if the unit were sitting in an open room, in front of you, a good technician could literally change this out in about 2 minutes. One main plug, two positives and two grounds. Always safety first and call a pro when dealing with electricity. **Side note** I did notice that my old breakers where the positive and negative main wires connected, my old breakers were much heavier duty connectors/metal. My father would have said my old ones looked like they were made in Detroit and this new one in China. Not complaining just full disclosure.

Heated up my home quickly! Works great! Piece of the breaker was broken on the back but, it didn't stop the breaker's function. Note to seller: Wrap the heater kit in protective bubble packaging or something to protect it during shipping. Install time was less than 30 mins. This was installed in my personal home's Air Handler Model # ARUF31B14.
