Emergency Heating Kits are an add on for many systems that allow your home to remain nice and toasty even if something drastic causes the main system to unexpected fail. They are a backup when needed, and a supplement on those extremely cold winter nights when it's nearly impossible to draw enough warmth out of the ambient environment. Emergency heat kits come in an assortment of capacities and configurations to meet almost any demand. Consult a licensed HVAC technician for your best fit!
