What is a patio door heater?
Stelpro manufactures three lines of patio door heaters: the ASPDHA series, the PDH series, and the SPDH series. With their traffic-resistant durability, these patio door heaters are designed to be installed in front of patio doors and bay windows. They are also well suited for installation in kitchens, living rooms, and solariums. These patio door heaters provide a constant flow of heat that creates a curtain of air that covers the entire door surface and prevents condensation or cold air from entering.
