Significance and Use
The energy input rate test is used to confirm that the patio heater is operating properly prior to further testing.
Preheat energy and time can be useful to food service operators to manage energy demands and to know how quickly the patio heater can be ready for operation.
The temperature distribution of a patio heater can be used by operators and designers to determine the most effective layout for a patio heating system.
The effective heated area can be used by operators to choose a patio heater that meets their heating needs.
1.1 This test method covers the heating performance and energy consumption of commercial radiant patio heaters. The food service operator can use this evaluation to select a commercial patio heater and understand its energy performance and effective heated area.
1.2 This test method is applicable to commercial gas and electric radiant patio heaters.
1.3 The patio heater can be evaluated with respect to the following:
1.3.1 Energy input rate (10.2),
1.3.2 Preheat energy consumption and time (10.3),
1.3.3 Temperature distribution (10.4), and
1.3.4 Effective heated area (10.4).
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
