Unit Heaters - Q-Mark MUH Series


MUH Unit Heater by Qmark UL LabelLakewood Logo
For safe, rapid heating that won't let you down, choose the QMark MUH portable electric convection heater. This cost-efficient unit quickly warms most rooms with a steel-sheathed heating element that features aluminum fins for maximum efficiency. The fan delay function ensures thorough, constant heating; the heating element warms up before the fan turns on, and the fan continues to circulate warm air after the heating element turns off. This alternation of functions keeps your space comfortable while conserving energy. The MUH features a Northern white baked enamel finish for a stylish contemporary appearance that complements any decor.
