Common questions from HVAC technicians, plumbers, boiler service companies, and facility managers about Laars (Teledyne Laars) OEM replacement parts. Contact us or call (901) 458-2000 with your model and serial number.
What is the difference between Laars and Teledyne Laars?
They are the same company at different points in its history. Laars was founded in 1948 in California. During a period of corporate ownership, the company was part of Teledyne Corporation and products were marketed as Teledyne Laars - that name still appears on millions of installed boilers and water heaters, and parts are listed under both names online. The company is now a subsidiary of Bradford White Corporation, headquartered in Rochester, New Hampshire. When searching for parts, either name leads to the same OEM parts.
What is the Laars RE0093200 aquastat (L6008G1009)?
The RE0093200 is a two-stage operating control and thermostat (aquastat) for Laars hydronic boilers. It uses a Honeywell L6008G1009 sensing element, has a temperature range of 130 to 230°F, and a 66-inch capillary. It controls boiler water temperature for proper operation and prevents overheating. It is one of the most widely ordered Laars replacement parts, used across multiple Laars series. Memphis Control Center stocks the RE0093200 - call (901) 458-2000 to confirm availability.
What does the Laars 2400-224 ignition module do?
The 2400-224 is a 24V ignition module (also described as a diagnostic control board) for Laars 2400 series boilers and water heaters. It controls the gas ignition sequence. When it fails, the unit will not attempt ignition. It is one of the most searched Laars parts online. Memphis Control Center stocks the 2400-224. Always confirm your boiler model and serial number when ordering an ignition module, as different Laars series use different ignition controls.
How do I find the correct replacement part for my Laars boiler?
Locate the model number and serial number on your boiler nameplate - typically on the front or side of the unit. Call Memphis Control Center at (901) 458-2000 with that information and we will identify the correct OEM part. Many Laars parts changed numbers over production runs (for example, E0093200 updated to RE0093200, E0100900 updated to RE0100900) - the serial number helps confirm which version applies to your unit.
What Laars series does Memphis Control Center stock parts for?
Memphis Control Center stocks Laars OEM parts for Mighty Therm (MT2 and legacy), NeoTherm, NeoTherm XTR, Pennant, Mascot FT, Mascot LX, Rheos pool heaters, JVH volume water heaters, Magnatherm FT, DVi, and legacy Teledyne Laars boilers and water heaters across the full production history. Laars covers 50,000 to 5,000,000 BTU/hr in natural gas, LP, and electric. Call (901) 458-2000 with your model and serial number for any Laars part.
Is Laars still in business and who owns them now?
Yes. Laars Heating Systems is active and manufacturing from its Rochester, New Hampshire facility, where every unit is live-fired before shipping. Laars is currently a subsidiary of Bradford White Corporation. The brand was founded in 1948 in California by engineer Avy Miller, was part of Teledyne Corporation (Teledyne Laars name), became part of Waterpik Technologies in 1999, and is now under Bradford White. Parts and service support for all Laars series remain available.
