Buy a heater accessory that works with your extruded aluminum baseboard heater model. An “H” at the beginning of the heater model’s name indicates a hydronic heater. It heats using water from your home’s hot water heater. Just like heating cables, this type warms a room evenly. Hydronic heaters have no dust or allergens. Buy an accessory for the correct intake. If your heater’s model ends in “T”, it indicates bottom intake. "F" indicates front intake. Make sure your accessories match with an SB or LB model. Only use accessories for the specific model intended. You cannot, for example, use a hydronic heater accessory on an electric or natural gas heater. Know the required accessories for your heater’s type of installation. Use end caps for stand-alone installation. Buy the right size accessory. A full-length heater that uses wall-to-wall installations needs a larger accessory than a smaller heater. In addition, you need to buy either a slope-top or a flat-top accessory, depending on your heater model.
