When sourcing or manufacturing home heaters for B2B export, the 1-year OEM warranty is one of the most common configurations you'll encounter. This standard warranty term has become an industry baseline for residential heating equipment, particularly for portable electric heaters, ceramic heaters, and oil-filled radiators targeting the consumer market.
But what does a 1-year OEM warranty actually cover? And more importantly, what doesn't it cover? Understanding these details is crucial for Southeast Asian sellers looking to sell on Alibaba.com and compete effectively in the global B2B marketplace.
Standard Coverage Scope
A typical 1-year OEM warranty for residential home heaters includes:
- Parts Replacement: Coverage for defective components including heating elements, thermostats, control boards, and internal wiring
- Labor Costs: Manufacturing labor for repair or replacement (note: on-site service labor is often excluded or requires separate agreement)
- Product Replacement: If repair is not feasible, manufacturers typically provide a replacement unit
- Shipping Costs: Varies by supplier—some cover return shipping for defective units, others require buyers to bear this cost
Commonly Excluded Items (Wear Parts)
Understanding what's NOT covered is equally important. Standard 1-year warranties typically exclude:
- Heating elements (considered consumable wear parts)
- Thermostats and temperature sensors
- Fan motors and blower assemblies
- Air filters and purification components
- Seals, gaskets, and insulation materials
- External casings damaged by misuse or accidents
- Damage from improper installation or unauthorized modifications
A warranty is essentially a manufacturer's promise to repair or replace system components if they fail under specific conditions. According to SMACNA, HVAC warranties are formal agreements covering repairs or replacements due to system defects within a predetermined timeframe. [6]
