A heating and cooling system for an electric vehicle includes an electric pump that pumps fluid around a first loop to selectively cool part of the drive train of the vehicle. The fluid passes through a cabin heater that extracts heat energy from the fluid and back to the part of the drive train. An electric compressor pumps fluid around a second loop through a condenser which extracts heat energy from the fluid which flows through an expansion valve and an evaporator and back to the electric compressor. A cabin chiller including an evaporator is located in a flow path receiving fluid output from the condenser through an expansion valve upstream in the flow path. The fluid from the evaporator is drawn back into the second loop by the electric compressor. The chilled fluid flowing through the evaporator extracts heat from the fluid flowing around the first loop.
