Answer: the wall radiator is to be preferred for long-term and continuous use. the mobile radiator is recommended for punctual and rapid use.
A wall-mounted heater will be fixed in a room in your home, and will likely stay in the same place for several years, probably until you decide to replace it. Being intended to be the main source of heat in the room, it will often be more powerful and more efficient than a mobile radiator, which will rather serve as an auxiliary heater. In return, a mobile radiator is obviously cheaper to buy than the wall. To choose between the two, you need to determine how much power you really need. If for example you want to heat a small room (like the bathroom) quickly and punctually, take a portable radiator. If, on the other hand, you want to heat a larger room (a bedroom or the living room) continuously, you will need a wall radiator. You too, send us your brico question
