BTU (British Thermal Unit)

BTU: A BTU is the energy needed to raise one pound of water 1°F. In foodservice, gas equipment is rated in BTU per hour (BTU/hr) — the burner's heat output. Higher BTU means faster heat-up and recovery, but also more gas use and more ventilation.

Why it matters when buying

BTU/hr tells you how hard a gas appliance can push heat. A high-volume line wants high BTU for fast recovery between loads; a low-volume kitchen pays for gas and hood capacity it won't use. Match BTU to your peak cooking demand, not the biggest number available.

How to read it on a spec sheet

Look for 'total BTU/hr' and per-burner BTU. Gas ranges list the sum of all burners plus the oven. Confirm your gas supply and regulator can deliver the rated input, and that your hood's CFM is sized for it.
