The present invention relates to a novel convection radiator. A convection radiator comprising a system of air circulation by natural convection and a system of air circulation by forced convection including an air convection means, such as a turbine, each of the two air circulation systems comprising a first air circulation passage, a second air circulation passage, and a heating element separating the two passages, wherein the said second passage of the said system of air circulation by natural convection is also the said first passage of the said system of air circulation by forced convection, the warm air outlet of the said system of air circulation by forced convection being located substantially at ground level, a single heating element thus being common to both said air circulation systems.

1. A convection radiator for functioning alternatively in a natural or in an air-flow inverting forced-convection heating mode, comprising: an enclosure having a bottom wall panel, heater means located within said enclosure, fan means including motor means located within said enclosure, an upper opening in said enclosure forming an inlet for cold air during forced convection heating and an outlet for warm air during natural convection heating, lower opening means provided in a bottom region of said enclosure at least adjacent said bottom wall panel forming an outlet for warm air during forced convection heating and an inlet for cold air during natural convection heating and control system means for controlling the operation of said heater means and said fan means as a function of predetermined temperature levels, and wherein said fan means are situated near said bottom wall panel of said enclosure substantially in front of said lower opening means forming an outlet for warm air during forced convection heating and said heater means are the only heater means operative during forced convection and natural convection heating with in both cases producing their maximum heating power and are situated only above said fan means and in a bottom area of said enclosure and upwardly from the fan means in the air current path through said radiator during forced-convection heating. 2. A convection radiator for functioning alternatively in a natural or in a forced-convection heating mode, comprising: an enclosure, electric heater means located within said enclosure, fan means including motor means located within said enclosure, an upper opening in said enclosure forming an inlet for cold air during forced convection heating and an outlet for warm air during natural convection heating, lower opening means provided in a bottom region of said enclosure forming an outlet for warm air during forced convection heating and an inlet for cold air during natural convection heating, and control system means for controlling the operation of said heater means and said fan means as a function of predetermined temperature levels, said control system means comprising circuit means including thermostat means and contact means controlled by said thermostat means for switching on or off said heater means and said fan means, wherein said heater means and said fan driving motor means are each connected in a separate control circuit and said thermostat means includes two separate thermostats, each thermostat controlling a contact means included in one of said circuit means for switching on or off a respective one of said fan means and said heater means independently from one another and having a lower switching on level and upper switching off level, the thermostat for controlling the fan means being responsive to the temperature in a region proximate to the floor of the space to be heated and the thermostat for controlling the heater means being adapted for being responsive to the temperature substantially spaced from said floor. 3. A radiator according to claim 2, wherein said lower opening means comprises an opening in a front panel of said enclosure in the lower region thereof for forming said outlet for warm air during forced convection heating and wherein said fan means are located substantially in front of said opening. 4. A radiator according to claim 2, wherein said single heating element consists of a resistor mounted above said fan means in the bottom portion of said enclosure. 5. A convection radiator for functioning alternatively in a natural or in a forced-convection heating mode, comprising: an enclosure, electric heater means located within said enclosure, fan means including motor means located within said enclosure, an upper opening in said enclosure forming an inlet for cold air during forced convection heating and an outlet for warm air during natural convection heating, lower opening means provided in the bottom region of said enclosure forming an outlet for warm air during forced convection heating and an inlet for cold air during natural convection heating, and control system means for controlling the operation of said heater means and said fan means as a function of predetermined temperature levels, said control system means comprising circuit means including thermostat means and contact means controlled by said thermostat means for switching on or off said heater means and said fan means, wherein said heater means and said motor means for driving said fan means are each connected in a separate control circuit and said thermostat means includes two separate thermostats, each thermostat controlling a contact means included in one of said circuit means for switching on or off a respective one of said fan means and said heater means, independently from one another, each thermostat having a lower switching on level and an upper switching off level, the thermostat for controlling the fan means being responsive to the temperature in a region proximate to the floor of the space to be heated and the thermostat for controlling the heater means being adapted for being responsive to the temperature substantially spaced from said floor, and wherein said fan means are situated in the bottom area of said enclosure and said heater means are formed by a single heating element situated above said fan means. 6. A radiator according to claim 5, wherein said lower opening means comprises an opening in a bottom panel of said enclosure for forming the inlet for cold air during natural convection heating. 7. A convection radiator for functioning alternatively in a natural or in an air-flow inverting forced-convection heating mode, comprising: an enclosure having a bottom wall panel, heater means located within said enclosure, fan means including motor means located within said enclosure, an upper opening in said enclosure forming an inlet for cold air during forced convection heating and an outlet for warm air during natural convection heating, lower opening means provided in a bottom region of said enclosure at least adjacent said bottom wall panel forming an outlet for warm air during forced convection heating and an inlet for cold air during natural convection heating and control system means for controlling the operation of said heater means and said fan means as a function of predetermined temperature levels, and wherein said fan means are situated near said bottom wall panel of said enclosure substantially in front of said lower opening means forming an outlet for warm air during forced convection heating and said heater means are the only heater means operative during forced convection and natural convection heating with in both cases producing their maximum heating power, said heater means consisting of a single heating element and are situated only above said fan means and in a bottom area of said enclosure and upwardly from the fan means in the air current path through said radiator during forced-convection heating.
