3 kW Heat Kits

Minimal backup heat for a heat pump

An electric heat kit is a set of resistance elements that install in an air handler to add heat. At 3 kW it provides modest backup (auxiliary) heat that a heat pump calls on during the coldest hours or defrost — enough for mild climates or small spaces without a large electrical draw.

• Auxiliary heat — supplements a heat pump on cold days.
• Low draw — modest electrical load, easy to feed.
• Mild climates — sufficient where winters are light.
• Air-handler match — confirm the kit fits your unit.
