A fan convector heating unit (10) has a housing (11) having an air duct (12) extending therethrough. A heat exchanger (21) is disposed within the air duct (12) and is adapted for fluid connection to a water heating system, when the heating unit (10) is installed. A fan (18) is disposed within the housing (11) and is arranged to cause air to flow through the air duct (12) and over the heat exchanger (21). Control means are provided to activate and deactivate the fan (18) upon the water within the heat exchanger (21) reaching pre-determined activation and deactivation temperatures. Both the activation and deactivation temperatures are interchangeably variable between standard and low energy activation and deactivation temperatures. Switching means (16), in communication with the control means, are provided to enable variation between a standard operating mode in which the standard activation and deactivation temperatures are employed, and a low energy operating mode in which the low energy activation and deactivation temperatures are employed.
