Gas Hobs: Your Questions Answered

When sourcing gas hobs, importers and brand owners often have the same questions. Here are answers to the most common inquiries we receive — covering everything from burner configurations and gas types to certifications and installation requirements.

Q1: What types of gas hobs are available?

Gas hobs come in several configurations to suit different kitchen designs and cooking needs.

Built-in gas hobs are installed flush with the countertop, creating a seamless kitchen surface. This is the most popular configuration worldwide, offering a premium appearance and easy cleaning. Typical dimensions range from 710×390mm to 750×430mm, with cut-out sizes varying by model.

Standalone gas cookers combine a gas hob with an oven in a single freestanding appliance. This configuration requires no cabinetry modification, has a compact footprint, and offers all-in-one convenience. These are particularly popular in rental properties, small kitchens, and developing markets.

Commercial gas hobs are heavy-duty units designed for restaurant and catering applications. They feature durable construction, multiple burner configurations, and high output for demanding cooking environments.

Q2: How many burners should I choose?

The number of burners depends on your target market and household size.

Double burner hobs are the most common residential configuration, suitable for small to medium-sized households. Heat load typically ranges from 5.0–5.2 kW per burner. These models are available in both tempered glass and stainless steel finishes.

Four burner hobs provide flexibility for larger households and more complex cooking. Total heat load is typically 8.25 kW, featuring a combination of rapid, standard, and auxiliary burners. Standard dimensions are 600×510mm with cut-out of 560×480×R20mm.

Five burner hobs add a wok burner for high-heat cooking applications. These are particularly popular in Southeast Asian and Middle Eastern markets. Total heat load reaches 10 kW with dimensions ranging from 760×510mm to 860×510mm.

Six burner hobs are designed for large families and semi-professional use, offering maximum flexibility. Total heat load is 11.75 kW with dimensions of 860×510mm and cut-out of 840×480×R20mm.

Q3: What materials are used for gas hobs?

Tempered glass is the preferred material for premium models. It offers contemporary aesthetics, is easy to clean, resists scratching and staining, and is available in various colors. Standard thickness is 8mm. This material is particularly popular in Europe, the Middle East, and premium Asian markets.

Stainless steel remains popular for its durability and professional appearance. It resists high temperatures and offers good value for money. Common grades are 201 stainless steel for entry to mid-range models and 304 stainless steel for premium applications. This material is preferred in commercial applications, value-conscious markets, and North America.

Q4: What is the difference between pulse ignition and piezoelectric ignition?

Pulse ignition (electronic) uses electronic spark generation for instant flame activation. Advantages include instant ignition, consistent performance, no matches required, and often includes automatic re-ignition. Power source is typically a 1.5V battery or 110/220V mains connection. This is the most common ignition type in premium models.

Piezoelectric ceramic ignition generates a spark through mechanical pressure on a ceramic element. Advantages include no batteries or mains power required, simple and reliable operation, and lower manufacturing cost. Disadvantages include potentially requiring multiple attempts and no automatic re-ignition. This system is commonly found in entry-level and value models.

Q5: What certifications do gas hobs need?

Certification requirements depend on your target market:

Gas hobs are strictly regulated due to the inherent safety risks of gas appliances. Always confirm certification coverage before placing your order. A reputable OEM/ODM manufacturer will have experience with these certifications and can assist with the documentation process.

Q6: What safety features should I look for?

Flame failure devices are mandatory in most regulated markets. Always verify that the manufacturer includes this feature as standard.

Q7: Can gas hobs be converted between natural gas and LPG?

Yes — most gas hobs are designed to accept either natural gas or LPG with simple conversion. The conversion typically involves replacing the burner jets (nozzles) to match the gas type and pressure. Some manufacturers also require adjusting the primary air intake for optimal combustion.

For importers targeting multiple markets, dual-fuel compatibility is a valuable feature. Discuss conversion kits and instructions with your manufacturer to ensure smooth adaptation for different markets.

Q8: What are the typical lead times for gas hob production?

Lead times depend on order size and customization requirements:

Q9: What payment terms are typical?

Common payment arrangements include:

Q10: Do you offer sample testing before bulk production?

Yes — most OEM/ODM manufacturers support sample orders prior to bulk production. This allows you to:

• Verify gas performance and heat distribution

• Test ignition reliability

• Confirm build quality and finishes

• Check flame failure device functionality

• Evaluate packaging durability for shipping

• Confirm customization specifications

Samples can be sent via international courier (DHL, FedEx, UPS) for fast delivery. Sample quantities typically start from 10 units for standard models.

Q11: How is quality control handled for gas hobs?

Gas system safety is non-negotiable, so quality control is particularly rigorous. Reliable manufacturers implement multi-stage quality control processes:

Incoming material inspection checks steel sheets, glass panels, burner components, and gas valves upon arrival.

In-process inspection monitors panel fabrication, burner assembly, gas path integrity, and electrical connections at each stage.

Final functional testing verifies ignition performance, flame stability, gas tightness, flame failure device operation, and heat distribution.

Safety testing confirms gas leak detection, overheat protection, and electrical safety compliance.

Many factories also offer third-party inspection support, allowing you to hire an independent inspector to verify quality before shipment.

Q12: How are gas hobs typically shipped?

Shipping options vary based on order volume and urgency:

Typical shipping terms include FOB Shenzhen, CIF destination port, or EXW factory. Ensure packaging is designed to protect glass panels and electronic components during transit. For glass-top models, reinforced packaging with edge protection is essential.

Q13: What are the installation requirements for gas hobs?

Ventilation is essential for gas hob operation. The installation area must have adequate airflow for combustion and ventilation. Built-in models require clearance below the unit for gas connection and ventilation, typically at least 50–100mm of free space beneath the hob.

Gas connection requires a certified gas installer to connect the hob to the gas supply. Verify the gas type (natural gas or LPG) matches the appliance configuration. All connections must be tested for leaks before use.

Electrical connection applies to models with electronic ignition and safety features. A grounded power outlet is required for models using mains power. Battery-operated models require no electrical connection.

Cut-out dimensions must be precise for built-in models. Standard cut-out sizes vary by model — typical dimensions range from 600×300mm for compact models to 840×480×R20mm for large configurations. Always verify the specific cut-out template provided by the manufacturer.

Q14: How do I maintain gas hobs?

Regular cleaning keeps the hob performing properly. Clean the surface after each use with a soft cloth and mild detergent. Avoid abrasive cleaners that can scratch glass or stainless steel. Remove burner caps and clean them separately to prevent clogging.

Burner maintenance ensures consistent flame performance. Clean burner ports regularly to remove debris. Check that burner caps are correctly positioned after cleaning to ensure proper flame distribution.

Gas connection inspection should be performed annually by a qualified technician. Check for leaks at all connection points. Verify that flexible hoses are not kinked, cracked, or deteriorating.

Ignition maintenance keeps the system reliable. Clean the spark electrode and thermocouple periodically. Replace batteries in battery-powered ignition systems as needed.
