Equipment
BTU (British Thermal Unit)
A unit of heat energy used to size grills, heaters, fire features, and pool heaters. Higher BTU = more heat output.
BTU ratings matter for: pool heaters (250K–400K residential), gas grills (40K–100K main burners), fire pits (60K–200K), patio heaters (40K typical). Always size up rather than down — undersized equipment runs longer and costs more over time.
