Offering a compelling blend of speed, efficiency, and safety, induction technology stands apart from traditional gas or electric radiant hobs. Within this category, the 700mm induction cooktop occupies a unique and increasingly popular niche. Positioned perfectly between the standard 60cm models and larger 80cm or 90cm units, the 700mm size provides an optimal balance of expanded cooking space and flexible integration into diverse kitchen designs. This article explores the comprehensive benefits and considerations of choosing a 700mm induction cooktop, guiding you through its features, installation nuances, and how it can elevate your everyday cooking experience.
Understanding the Core Advantages of Induction Technology
Before delving into the specifics of the 700mm size, it is crucial to appreciate the fundamental benefits that induction technology brings to the kitchen. These advantages are universal across all induction cooktop sizes and represent significant upgrades from older cooking methods.
Unparalleled Speed and Efficiency
Induction cooking works by creating a magnetic field that directly heats the cookware itself, rather than the cooktop surface. This direct energy transfer results in incredibly rapid heating times, often boiling water in half the time of a conventional electric hob or even faster than gas. This efficiency not only saves time but also conserves energy, as very little heat is lost to the surrounding air, making induction cooktops highly energy-efficient appliances.
Precision Temperature Control
One of the most lauded features of induction is its ability to offer incredibly precise and instantaneous temperature control. Unlike electric radiant coils that take time to heat up and cool down, induction responds immediately to power adjustments. This means you can go from a rolling boil to a gentle simmer with the touch of a button, providing chefs with unparalleled control over delicate sauces, chocolates, or critical searing temperatures. This precision mirrors the responsiveness of gas but without the associated heat loss.
Enhanced Safety Features
Safety is a significant advantage of induction cooking. Since the cooktop surface itself does not generate heat, it remains relatively cool to the touch, only warming up from residual heat transferred back from the hot cookware. This drastically reduces the risk of accidental burns, making it an ideal choice for households with children or elderly individuals. Furthermore, induction hobs typically feature automatic pan detection, where the heating element only activates when an appropriate pot or pan is placed on the zone, and auto shut-off functions if cookware is removed or left unattended for too long.
Effortless Cleaning
The smooth, flat glass-ceramic surface of an induction cooktop makes cleaning remarkably simple. Because the surface remains cool, spills and food splatters do not burn onto the surface, preventing stubborn, caked-on messes. A quick wipe with a damp cloth and mild detergent is usually sufficient to maintain a pristine cooktop, saving valuable time and effort in kitchen maintenance.
Why Choose a 700mm Cooktop? The Perfect Fit for Modern Kitchens
While the general benefits of induction are clear, the 700mm size offers specific advantages that make it an attractive option for a broad range of kitchen designs and cooking needs.
Optimized Cooking Zones and Flexibility
A 700mm cooktop typically accommodates more generous cooking zones than a standard 60cm model, or it provides larger, more powerful zones. This extra width often allows for four full-sized zones, or even a combination of larger zones with flexible "bridge" or "flexi-induction" areas. These flexible zones can be combined to create an extra-large heating surface, perfect for griddles, large roasting pans, or multiple pots simultaneously, offering a level of versatility often desired by serious home cooks without committing to a full 90cm appliance.
Bridging the Size Gap
The 700mm dimension effectively bridges the gap between smaller and larger cooktop options. For kitchens where a 60cm unit feels too restrictive but an 80cm or 90cm model would dominate the counter space or exceed cabinetry constraints, the 700mm offers a strategic compromise. It provides that essential extra width for comfortable multi-pot cooking without requiring a complete kitchen overhaul, making it a popular choice for renovations and new builds seeking optimal space utilization.
Aesthetic Integration and Design Freedom
Beyond functionality, the size of a cooktop plays a significant role in kitchen aesthetics. A 700mm induction cooktop can integrate seamlessly into various countertop layouts, providing a clean, minimalist look. Its slightly wider profile can help create a more balanced visual appeal, especially when paired with larger ovens or wider rangehoods, contributing to a cohesive and sophisticated kitchen design. For those with unique cabinetry specifications or slightly wider existing cut-outs, the 700mm option can be a perfect, tailored solution.
Key Features and Innovations to Look For
When selecting a 700mm induction cooktop, various features and technological advancements can significantly enhance its functionality and user experience. Understanding these options will help you choose a model that best suits your cooking style and preferences.
Power Levels and Boost Functions
Most induction cooktops offer a range of power settings, typically from 1 to 9, allowing for precise control. A crucial feature is the Power Boost function, which temporarily delivers maximum power to a single cooking zone, ideal for rapidly boiling water or searing meats. Look for models with boost functions on multiple zones if you frequently need high heat simultaneously.
Flexible Cooking Zones (Bridge, Flexi Zones)
Many 700mm models incorporate flexible cooking zones. These can be rectangular areas or two circular zones that can be "bridged" together with a single command to create one large heating surface. This is invaluable for accommodating oversized cookware like griddle plates, fish kettles, or large roasting dishes, offering unparalleled adaptability.
User Interface and Controls
Modern induction cooktops typically feature sleek touch controls integrated into the glass surface. Options include individual sliders for each zone, central master controls, or intuitive full-colour touchscreens. Some advanced models may even offer rotary dials that magnetically attach to the surface, providing tactile feedback reminiscent of traditional hobs but with induction precision. Consider which interface feels most intuitive and practical for your daily use.
Integrated Timers and Safety Locks
Timers are a standard and highly useful feature, allowing you to set a specific cooking duration for each zone, with an audible alert upon completion. Some timers can even switch off the zone automatically. Safety locks, or child locks, prevent accidental activation or changes to settings, providing peace of mind, especially in busy households.
Pan Detection and Auto Shut-off
As mentioned, induction cooktops only activate when a compatible pan is placed on the zone. The pan detection feature ensures energy is only consumed when needed. Furthermore, most models include an auto shut-off function that turns off a zone if it remains inactive or if cookware is removed for a prolonged period, enhancing safety and energy efficiency.
Ventilation Integration (Hob2Hood or Similar)
Some premium 700mm induction cooktops offer integrated ventilation control systems, often referred to by brand-specific names like "Hob2Hood." This technology allows the cooktop to communicate wirelessly with a compatible rangehood, automatically adjusting the fan speed based on the intensity of cooking, ensuring optimal air purification without manual intervention.
Installation and Kitchen Design Considerations
Integrating a 700mm induction cooktop into your kitchen requires careful planning, particularly concerning countertop modifications, electrical supply, and ventilation. Proper installation ensures both functionality and safety.
Countertop Cut-out Requirements
While the overall width is 700mm, the actual cut-out dimensions required in your countertop will be slightly smaller. Always refer to the manufacturer's specific installation guide for precise measurements for both width and depth. It is crucial to measure accurately or have a professional installer do so, as an incorrect cut-out can complicate installation and void warranties. Ensure there is adequate support around the cut-out, especially with delicate countertop materials.
Electrical Specifications
Induction cooktops, particularly larger models like the 700mm size with multiple powerful zones, require a dedicated high-power electrical circuit. This typically means a 32-amp or 40-amp circuit, depending on the cooktop's maximum power draw. It is imperative to consult a qualified electrician to ensure your home's electrical system can safely support the new appliance and that the correct wiring and circuit breakers are installed. Attempting to run a high-power induction cooktop on an insufficient circuit can lead to electrical hazards and performance issues.
Cabinetry and Ventilation Planning
Below the cooktop, sufficient space is required for the appliance's depth and for proper ventilation, as induction hobs require airflow to cool their internal electronics. If installing an oven directly beneath the cooktop, ensure there is adequate clearance between the two appliances as specified by both manufacturers. For ventilation, a rangehood matched to the cooktop's width (at least 700mm or wider) is recommended to effectively capture steam and odours. Consider ducted rangehoods for optimal performance.
Clearance and Heat Dissipation
While the induction surface itself doesn't get hot, the internal components generate heat that needs to be dissipated. Ensure there is adequate clearance around the cooktop, especially from adjacent walls or tall cabinets, to allow for proper airflow. Manufacturers provide minimum clearance specifications that must be adhered to for safety and optimal appliance longevity. Avoid sealing off the cooktop from below, as this can impede airflow and lead to overheating.
Maintenance and Longevity of Your 700mm Induction Cooktop
To ensure your 700mm induction cooktop remains in pristine condition and performs optimally for many years, consistent and correct maintenance is essential. Its robust design makes it relatively low maintenance, but attention to detail can prevent issues.
Daily Cleaning Routine
For daily upkeep, simply wipe down the cool glass surface with a soft, damp cloth and a mild dish soap or a specialized ceramic hob cleaner after each use. Immediately clean up any sugar-based spills (e.g., melted sugar, candy) while they are still warm but not scorching hot, as these can pit the glass if allowed to cool and harden. Avoid abrasive sponges, scourers, or harsh chemical cleaners, as these can scratch or damage the glass-ceramic surface.
Preventing Scratches and Damage
Although the glass surface is durable, it is not impervious to scratches. Always lift pots and pans rather than sliding them across the surface. Ensure the bottoms of your cookware are clean and smooth, free from any grit or rough edges. Avoid dropping heavy objects onto the cooktop. While the glass is strong, impact from a sharp, heavy item can cause cracks or chips. Use trivets when placing hot cookware off the hob to protect other surfaces and prevent accidents.
Troubleshooting Common Issues
Modern induction cooktops feature sophisticated diagnostics. If an error code appears, consult your user manual for specific instructions. Common issues might include inconsistent heating (often due to non-compatible or poor-quality cookware), or the cooktop not turning on (check power supply and safety locks). Most minor issues can be resolved by a quick power cycle (turning the cooktop off and on at the mains for a few minutes). For persistent problems, always contact a qualified technician or the manufacturer's support.
Understanding Induction Cookware Compatibility
A fundamental aspect of induction cooking, and often a point of initial confusion for new users, is the requirement for compatible cookware. Induction cooktops only work with pots and pans that have a ferromagnetic base.
The Magnet Test
The simplest way to check if your existing cookware is induction-compatible is to perform the "magnet test." If a magnet sticks firmly to the bottom of the pan, it will work on an induction cooktop. If the magnet does not stick, or only sticks weakly, the pan is not suitable for induction cooking. Materials like cast iron, magnetic stainless steel, and some enamel-on-steel pots are generally induction-compatible.
Optimal Cookware Characteristics
Beyond magnetism, the best cookware for induction has a flat, thick base. A flat base ensures maximum contact with the magnetic field, leading to efficient and even heating. Thick bases, often with multiple layers (e.g., an aluminum core sandwiched between stainless steel), provide superior heat distribution and retention, preventing hot spots and improving cooking results. While perfectly flat is ideal, a slight concavity (that flattens when heated) is acceptable. Avoid pans with warped or very thin bases, as these can cause uneven heating or noise.
It's also worth noting that the size of the pan should ideally match the size of the induction zone it's placed on, or be slightly smaller. While induction still works with smaller pans on larger zones, energy efficiency is optimized when the pan covers most of the zone's active area.
Making the Right Choice: Factors to Consider
Choosing the right 700mm induction cooktop involves evaluating several factors that align with your culinary needs, lifestyle, and budget. Thoughtful consideration of these points will ensure satisfaction with your investment.
Cooking Habits and Lifestyle
Consider how you cook. Do you frequently entertain and use multiple large pots simultaneously? If so, flexible zones and a generous number of powerful heating elements on a 700mm model will be beneficial. If you typically cook for one or two, a simpler 700mm model with robust standard zones might suffice. Think about the types of dishes you prepare – precise temperature control is excellent for delicate tasks, while boost functions are invaluable for quick meals.
Budget and Brand Reputation
Induction cooktops vary widely in price, influenced by features, brand, and build quality. Establish a realistic budget but also consider the long-term value. Reputable brands often offer superior customer service, extended warranties, and proven reliability. Researching reviews and comparing models from trusted manufacturers can provide insights into performance and durability. While an initial investment might be higher than traditional cooktops, the energy savings and enhanced cooking experience can justify the cost over time.
Future-Proofing Your Kitchen
A kitchen renovation or appliance upgrade is a significant investment, so consider future needs. As kitchens become smarter, features like Wi-Fi connectivity, integration with smart home systems, or advanced safety sensors might become more prevalent. While not strictly necessary, thinking about how technology might evolve can help you choose a cooktop that remains relevant and enjoyable for years to come. The 700mm size itself is a forward-thinking choice, offering more functionality than a compact unit without the full commitment of a very large model.
