  • Can I install my Laars water heater or boiler myself?

    No. Laars mandates that all products be installed and serviced by a professional service technician qualified in water heater installation. Improper installation can create safety hazards and will void the warranty.

  • How often should I service my Laars heating system?

    Regular maintenance checks are recommended at least once a year to ensure optimal performance, efficiency, and safety.

  • What should I do if I smell gas near my Laars appliance?

    Do not try to light any appliance or touch electrical switches. Immediately evacuate the area and call your gas supplier from a neighbor's phone. If you cannot reach them, call the fire department.

  • Where can I find warranty information for my Laars product?

    Warranty documents can be found in the Document Library on the official Laars website, or you can check the specific warranty certificate provided with your unit installation manual.
