CKD & OEM Service for Storage Electric Water Heaters
Component kits, private-label OEM/ODM manufacturing, and full assembly support — supplied by an electric water heater manufacturing base in Huangpu Town, Zhongshan, China, whose products and solutions reach more than 50 countries and regions.
Wulinfeng supplies storage electric water heater tanks and complete units in three forms: as a finished product (CBU), as a semi-knocked-down assembly (SKD), and as a component kit (CKD) for local assembly. If your market applies tariffs, local-content requirements, or import restrictions to fully assembled appliances, a CKD programme lets you assemble locally, control the final cost, and build your own brand at the same time.

Service Models: OEM / ODM / SKD / CKD
The industry uses these four terms loosely. Before quoting, we agree in writing on what your kit actually contains.
| Model | What it normally means | What you must be able to do locally |
|---|---|---|
| CBU | Complete unit, ready to install | Retail or light assembly only |
| SKD | Semi-knocked down: major assemblies pre-built | Final assembly, wiring, testing, packaging |
| CKD | Component kits: parts grouped by assembly stage | Tank assembly, wiring, pressure and electrical testing, packaging |
| OEM / ODM | Built to your brand, drawing, or design | Distribution and after-sales in your market |
We supply a bill of materials with part numbers and quantities per unit — not a general description — so that scope, classification, and pricing are never left open.
What a CKD Kit Contains
Using a storage electric water heater as an example, a kit is grouped by assembly stage:
| Stage | Typical components |
|---|---|
| Tank & liner | Enamel steel liner / inner tank, flanges, tank fittings |
| Heating & control | Heating element, thermostat, temperature control, safety components |
| Electrical | Control panel, wiring, cable, plug and circuit protection options |
| Housing & fittings | Shell, brackets, valves, small fittings, fasteners |
| Branding | Rating label, manual, colour box and packaging in your language |
Tooling and moulds are part of the scope discussion: our service model covers drawing-based processing, full-tooling mould development, custom design, and component kits, with mould ownership and programme terms fixed in writing before tooling starts.
Why Importers Choose CKD
- Reduce tariff exposure. Components are normally assessed differently from finished appliances; we support your customs broker with bills of materials, part numbers and packing lists so classification can be confirmed before shipment.
- Meet local-content requirements. Local assembly and value addition are increasingly required in fast-growing markets such as India, Indonesia, Vietnam, Thailand, Egypt and Turkey.
- Lower freight volume. Kits pack denser than assembled units, which reduces shipping cost per sellable unit.
- Build your own brand. Rating plates, manuals and packaging are produced for your brand and your market language.
Specifications & Standards
| Item | Specification |
|---|---|
| Liner / tank standard | Enamel steel liner, built around a 0.8 MPa pressure standard, corrosion-resistant and pressure-resistant |
| Capacities | 40 / 50 / 60 / 80 / 100 / 150 / 200 L (household and commercial series) |
| Power range | Multi-power adaptability, 2200 W to 5000 W |
| Electrical configuration | Voltage, frequency, plug, cable and thermostat options matched to your destination market |
| Certifications held | CE (EU), UL (U.S.), ISO 9001, ISO 14001, KC (Korea) |
| Quality system | Full production-chain quality management, dedicated testing centre and durability laboratory |
Local safety, energy and import certifications required by your market remain part of the programme scope: we agree in writing which party supplies test reports and technical files, which party holds the local certificate, and which party pays for local testing.
OEM & ODM Customisation
- Product definition and R&D support for new models
- Drawing-based processing and full-tooling mould development

- Private label: logo, rating plate, manual, colour box and packaging
- One kit platform serving several price positions in the same market
How a Programme Starts
- Choose your model. Pick the product for your market and set the specifications with us.
- Define the scope. We confirm which components you buy from us (including tooling and moulds), and which are handled locally or with our training and remote support.
- Order your components. Enamel inner tanks, control panels, heating elements, fittings and packaging, documented by part number.
- Assemble and test. We back you with technical documentation, training and support through assembly, pressure testing and final inspection.
Documentation, Training & After-Sales Support
- Bill of materials, part numbers and packing list for every order
- Pressure test records for liners and pre-shipment inspection against the bill of materials
- Assembly instructions and sample-kit validation before the first full order
- Technical training and a named technical contact on the supplier side
- Stable part numbers and a spare parts list covering heating elements, thermostats, safety components and fittings
- Sea-worthy packaging that protects enamel surfaces and electrical parts in humid transit
MOQ per model, mould ownership, first-order and repeat-order lead time, payment terms and the inspection trigger are all fixed in the written agreement before production starts.
Before You Order: Buyer’s Checklist
Kit scope, liner standard, certification responsibility, customs classification, electrical configuration and after-sales terms are the six points that decide whether a CKD programme is repeatable. We have published a detailed ten-point checklist for CKD buyers:
