I found this heater discarded on the street - I guess the owners tossed it out the window a day or so ago when the historic heat-wave was at its hottest.
The heater boasts:
• Patented SCHWARZ heating element heats faster than conventional screened elements
• Greater heat transfer = more efficient
• Silent convection heat
• Electonmechanical thermostat maintains the desired temperature level
• Wall mountable
• Overheat protection
• Silent convection heat
And they just couldn't take having these features in their house any more.
