ITEMDESCRIPTIONMODEL NUMBERS / PART NUMBERSHow do I tell the age of a Lochinvar water heater from the serial number?
Tuesday, September 11, 2018
Lochinvar uses a 20-letter code for the year of manufacture of their water heaters. The first letter of the serial number is the one to use. The letters I, O, Q, R, U and V are excluded. Because the letter code recycles every 20 years “A,” for example, can be 1964, 1984, 2004. You have to use your own judgement of the condition of the water heater to determine which year is correct. Knowing when the house was built is also helpful.
A = 1964, 1984, 2004 B = 1965, 1985, 2005 C = 1966, 1986, 2006
D = 1967, 1987, 2007 E = 1968, 1988, 2008 F = 1969, 1989, 2009
G = 1970, 1990, 2010 H = 1971, 1991, 2011 J = 1972, 1992, 2012
K = 1973, 1993, 2013 L = 1974, 1994, 2014 M = 1975, 1995, 2015
N = 1976, 1996 P = 1977, 1997 S = 1978, 1998
T = 1979, 1999 W = 1980, 2000 X = 1981, 2001
Y = 1982, 2002 Z = 1983, 2003
The data plate for the Lochinvar water heater shown below has a first letter of “X” and, based on the its condition, we determined it was manufactured in 2001.
