Narrative:

On climb out from ZZZ; the left engine fuel heat light came on uncommanded. Fuel temperature and oil temperature started to rise indicating valve was open. QRH procedure was followed and called maintenance to confirm situation and options. Maintenance confirmed that we would need to follow QRH procedure for high oil temperature in caution range for 15 mins requiring left engine precautionary shutdown. We declared an emergency with ATC and turned back for single engine landing. We finished up fuel heat and high oil temperature QRH procedure and started left engine in-flight shutdown QRH checklist. We started descent into ZZZ completing single engine; emergency landing; and overweight landing checklists along with the normal checklists. Notified flight attendants and passenger of return to departure airport and reason. They performed their procedures on descent and prepared the passenger for landing. Normal single engine approach and landing at 134.4 gross weight and sink rate of 400 FPM. Crash fire rescue equipment equipment was standing by but not needed.
