Plug the mobile heater into the socket, switch it on and the room heats up. According to the information provided by the manufacturer about this product, the Alpha Heater works that easily. In reality, there are quite a few requirements to be observed for the 350-watt heater. This starts with the size of the room. Due to its handy size, the mobile heater is only suitable for rooms with a total size of up to 12 m². Accordingly, in larger rooms, several of the socket heaters would have to be distributed in order to notice the heat throughout the room. The number of sockets is often limited, so this option is not available in all rooms. It is therefore advisable to measure the room beforehand and to consider whether the Alpha Heater is an alternative to a classic radiator or not.
