Manufacturer Warranty & Commercial Returns Policy

Last updated: October 2026

In commercial HVAC and hydronic systems, equipment reliability and supply-chain authenticity are vital to system performance. Fourlanos B2B provides mechanical contractors, facility managers, and trade installers with manufacturer warranty support and transparent commercial return procedures.

1. 100% Genuine OEM Equipment Policy

Fourlanos B2B operates exclusively through verified European factory lines and authorized distribution channels:

  • Authorized Brands: Honeywell Home / Resideo, Grundfos, Belimo, Danfoss, Siemens, Wilo, TA Hydronics, and other leading European manufacturers.
  • Traceable Authenticity: Every valve, pump, sensor, and electronic actuator carries original factory serial numbers, CE compliance markings, and manufacturer documentation.
  • Zero Counterfeits: We strictly reject refurbished, uncertified gray-market, or replica components that risk system hydraulic imbalances or safety violations.

2. Standard Manufacturer Warranty Coverage

All equipment supplied by Fourlanos B2B is backed by the official standard European manufacturer warranty:

  1. Duration: Warranties typically range from 12 to 24 months from the date of invoice, depending on the manufacturer’s specific product line guidelines.
  2. Coverage Scope: Covers defects in materials and manufacturing workmanship under normal operating conditions specified in technical datasheets.
  3. Exclusions:
    • Normal wear and tear of consumable components (e.g. mechanical seals, gaskets, filters).
    • Improper electrical wiring, incorrect voltage supply, or absence of electrical phase protection.
    • Dry running of circulator pumps or severe water cavitation damage.
    • Operating outside specified pressure, temperature, or chemical glycol concentration limits.
    • Modifications or unauthorized disassembly without manufacturer consent.

3. Warranty Claim & Technical Verification Protocol

If a component is suspected of a manufacturer defect during the warranty period:

  1. Initial Notification: Contact our Athens trade desk at [email protected] with:
    • Invoice / Order number
    • Part number and serial number photo
    • Detailed description of operating symptoms and electrical/hydraulic parameters
  2. Technical Review: Our trade team reviews operating conditions and issues a formal Return Merchandise Authorization (RMA) number.
  3. Factory Evaluation: The component is returned to our Athens logistics hub or directly to the manufacturer’s regional testing laboratory for technical diagnostics.
  4. Resolution: If a manufacturing defect is verified, the manufacturer will repair or replace the unit according to standard warranty protocols.

4. Commercial Returns & RMA Procedures
