PAMTTON offers instant electric water heaters in power ranges from 5500W to 8500W:

  • 5500W (P1-H5529): Suitable for moderate climates, regions with limited electrical capacity
  • 7500W (DF-75): Ultra-thin design, balanced performance
  • 8500W (P1-H8545): Maximum heating power for colder climates, higher flow rates

All models operate on 220V-240V, 50-60Hz. The choice depends on the target market's electrical infrastructure and climate conditions.

Instant water heaters save 30-40% energy compared to storage heaters because:

  1. No standby heat loss: Storage heaters continuously reheat water to maintain temperature, wasting energy even when not in use. Instant heaters only activate when hot water is needed.
  2. On-demand heating: Water is heated only for the duration of use (typically 10-15 minutes per shower), not 24/7.
  3. High efficiency heating elements: PAMTTON uses bare wire heating elements with 98%+ thermal transfer efficiency.
  4. No tank maintenance: Eliminates energy costs associated with tank insulation and anode rod replacement.

OEM / ODM

OEM (Original Equipment Manufacturer): The buyer provides design specifications and the manufacturer produces to those specs. The buyer's brand goes on the product. Example: You send us your water heater design, we manufacture it with your logo.

ODM (Original Design Manufacturer): The manufacturer designs the product and the buyer selects from existing designs, customizing branding and minor features. Example: You choose from our P1/DF/S1/A/X2/B series, we add your logo, packaging, and any color changes.

PAMTTON offers both OEM and ODM services. For most buyers, ODM is faster and more cost-effective since the product is already designed and certified.
