The use of tubular energy efficient room heaters components: the external armored steel protection, filled with high-quality composite magnesium powder, the center is made of special alloy heating resistor, the external design with a special high-strength aluminum alloy plate integrated into the radiation heat dissipation Plate assembly to constitute a gas indoor heaters element assembly. When the power supply is turned on, the metal-covered resistor together with the heat sink generates heat in the interior of the device, the center of the heat source causes the radiator to heat and the surrounding object is radiated and heated through the vents in front of the device Convection heating air, double heating, so that the installation of the equipment room heat and the required temperature is guaranteed. The machine and thermostat are easy to install and use, and can be equipped with automatic programmable liquid crystal display wall thermostat and other wall thermostats.
