- D. REDUCED SET OF BOILER MODELS AND CHARACTER ISTICS

- D.1 IN TRODUCTION

This appendix presents the approach for developing a reduced set of boiler models and

the resulting boiler characteristics

.

7

- D.2 REDUCED SET OF BOILER MODELS DATABASE

7

- D.2.1 Purpose

The reduced s et of b oiler m odels was developed to identify actual unique boiler mode ls

which represent units with different design characteristics

. This reduced data set wa s then

expand ed by adding information provided in the manufacturers' product literature.

The September 2013 Air

- Conditioning, Heating, and Refrigeration Institute (AH RI)

Directory 1 

### provided the basis for the reduced set of models, since it is frequently update d and

includes useful data for each model. Not all boiler manufacturers are part of AHRI

, however , so

DOE also look ed at other model directories

, including the California Energy Commission

( CEC )

, 2 

### Energy Star, 3 

### and Natural Resources Canada ( NRCAN )

. 4



### The September 20 13 AHRI Directory 1 

### lists more than 2652 boiler models . The set of

boiler models was then e xpand ed with data from CEC ( 5464 models ) , Energy Star ( 940 models

and group s of models )

, and NRCAN (1475 models ). Many models represent essentially identical

units that differ only i n brand name. The database of gas hot water boiler models described here

(referred to as the reduced set of boiler models or simply the reduced set) represents non

repetitive boiler models only. After examining the AHRI Directory database, the Department

d etermined that about 1331 models (654 hot water gas boilers, 83 steam gas boilers, 501 hot

water oil boilers, and 93 steam oil boilers) may be considered sufficiently different to be listed

as unique models. See the LCC spreadsheet (“Models Directory” work sheet) for a complete

listing of models used for each boiler product class.

Once the reduced set was identified, DOE examined the manufacturer’s product literature

and added additional data

. DOE identified the main boiler manufacturers, shown in Table 7

-

D.2.1 , and the trade names of their boiler lines. Table 7

- D.2.2 shows the parent companies and

number of models by product class in the reduced data set.
