ZeeKee 7pc Glow Plug Repair Kit
This replacement kit includes ceramic glow plugs and gaskets listed as compatible with many Chinese 2KW, 5KW, and 8KW diesel heaters and some Eberspacher part equivalents.
The product lists specific part replacements and emphasizes high-temperature ceramic construction for durability. It is intended for maintenance or field repair to restore ignition reliability.
Compatibility claims and part numbers are provided, which can help in cross-referencing part fitment before purchase or repair work.
VEVOR Diesel Heater Pipe Ducting Set
The VEVOR ducting set is specified to fit 2KW/5KW/8KW diesel heaters and includes a stainless steel exhaust pipe, extendable air outlet ducts, air vent connectors, a tee outlet, and clamps.
Features listed include an extendable length for outlet ducts (600–700 mm) and a rust-proof stainless exhaust pipe. The interior aluminum foil-lined ducting is described as high-temperature resistant.
This kit provides components commonly required for routing heated air and exhaust safely and can be used to support proper installation and airflow distribution in vehicle or marine installations.
Buying Guide: How To Choose A 2KW Diesel Heater
Heating Power And Coverage
Rated Power (2KW) indicates the heater’s output under specified conditions. For enclosed vehicle spaces such as vans, small RVs, and boats, a 2KW unit typically targets ~100–170 ft² depending on insulation and ambient temperature.
Compare the manufacturer’s applicable range and warm-up time to match your space. Consider interior volume, ceiling height, and insulation when estimating suitability.
Voltage Compatibility And Power Options
Most 2KW units operate on 12V, but some offer 12/24V compatibility or optional AC adapters. Confirm vehicle electrical system compatibility and alternator or battery capacity, especially for extended run times.
Dual-voltage or AC-supported models expand installation flexibility for off-grid battery systems or stationary use.
Fuel Consumption And Tank Capacity
Fuel consumption rates are commonly stated in L/h or gal/h. Lower consumption supports longer runtime from a fixed tank. Verify whether the unit has an integrated tank (all-in-one) or requires an external feed from the vehicle fuel tank.
All-in-one designs add convenience but increase footprint. External-fed models may integrate with vehicle fuel lines for extended operation.
Controls And Connectivity
Control interfaces include wired LCD controllers, remote controls, and Bluetooth app control. App control can enable preheating, while wired controllers offer direct, reliable operation without wireless dependencies.
Consider the range and redundancy: units that include both remote and wired controller provide flexibility in different scenarios.
Altitude Compensation And Cold-Start Performance
Automatic altitude compensation adjusts combustion parameters to maintain heater performance at high elevations. If you travel to high altitudes, prioritize models that specify altitude capability.
Cold-start capability and rated operating temperature ranges determine if the heater will reliably start in extreme cold.
Safety Features
Important safety features to prioritize: CO detection or alarm, overheat protection, leak-proof fuel caps, and fuel level indicators. A built-in CO alarm can provide an extra safety layer for indoor or vehicle-installed applications.
Assess whether the unit includes automatic shutoff behaviors for fault conditions and verify installation recommendations to minimize exhaust intrusion risks.
Installation And Ducting
Installation impact: all-in-one units typically simplify mounting but require appropriate clearance and ventilation. Split-type heaters allow more flexible placement of the combustion and air exchange components.
Proper exhaust routing, intake sealing, and ducting kits are essential for safe operation. Accessories like stainless exhaust pipes, clamps, and outlet ducts support compliant installations.
Maintenance And Spare Parts
Routine maintenance items include glow plugs, fuel pump, filters, and gaskets. Verify availability of replacement kits and compatibility with your heater model before purchase.
Kits that include commonly worn parts can reduce downtime. Check vendor support channels and documentation for recommended service intervals.
Noise, Pump Quality, And Durability
Noise levels vary by blower and fuel pump design. If low operational noise is important, compare specifications and user-specified pump noise characteristics.
Metal-bodied pumps and ceramic ignition elements are commonly associated with longer service life, according to product listings.
Accessory Compatibility
Confirm that ducting sets, mounting brackets, and repair kits list explicit compatibility with 2KW models. Using parts designed for the heater series can simplify installation and maintenance.
When retrofitting, check the physical dimensions and hose diameters to ensure proper fitment.
Comparison Perspectives
- All-In-One vs Split-Type: All-in-one simplifies installation but can be bulkier. Split systems allow hidden combustion units and more flexible ducting.
- 12V Only vs 12/24V or Dual Power: Dual-voltage models add flexibility for different vehicles or off-grid setups.
- Control Options: Wired controllers provide reliability; Bluetooth/app control provides convenience for remote preheating.
- Safety Emphasis: Models listing CO alarm and overheat protection are better suited when heaters operate inside occupied cabins.
Installation Checklist
- Verify vehicle battery and alternator capacity for continuous operation.
- Plan exhaust routing to avoid cabin ingress and ensure safe clearance from flammable materials.
- Use stainless or rated exhaust components and secure clamps to prevent leaks.
- Install monitoring (CO alarm, temperature) where heaters operate near living spaces.
Final Selection Tips
Match heater coverage and fuel consumption to your space and planned runtime. Prioritize models with the safety features and control interfaces you need. Factor in installation complexity and confirm accessory and spare part compatibility before purchase.
