Buying an electric hob: how to choose the right model for your kitchen

An electric hob may seem simple to choose: decide how many cooking zones you need, pick a black glass model and check the price. In practice, the biggest differences come down to the connection, cut-out size, heating technology and controls. A model that’s ideal for a student room won’t necessarily suit a busy household.

Common pitfalls when choosing an electric hob

1. Checking the connection only after buying

A built-in hob rated at 6,000 to 7,400 watts may require a multi-phase connection. Some models come with a cable but no plug, and need to be connected by a qualified installer. So a standard socket isn’t always enough.

Before buying, check:

  • the total connected load in watts;
  • how many phases are required;
  • whether a Perilex or fixed connection is needed;
  • the manufacturer’s instructions and your consumer unit.

A compact electric hob rated at 2,000 to 3,000 watts is often easier to install, but you should still check that your existing circuit can handle the load.

2. Confusing the overall dimensions with the cut-out size

A 60 cm hob is rarely exactly 60 cm wide. Its overall width might be around 59 cm, while the worktop cut-out may need to be about 56 cm wide. For an 80 cm hob, the cut-out is often around 78 cm, but this varies by model.

So always measure:

  1. the available space in the worktop;
  2. the width, depth and height of the cut-out;
  3. the clearance beneath the hob;
  4. the distance from the oven, drawer and extractor.

Use only the official dimension drawing for the product you’ve chosen. Even a small discrepancy could make installation impossible.

3. Treating handy features as the deciding factor in technology

A hob with touch controls, a timer or a child lock can be convenient, but these features alone tell you little about cooking performance. First, look at the heating type and controls.

  • A ceramic hob heats the glass surface, which then heats the pan. The surface stays hot after the hob is switched off.
  • An induction hob works with suitable pans that have a magnetic base. The product design heats the pan directly, though the glass around the pan may still get warm.
  • A classic electric hob with rotary controls is easy to use, but may have fewer automatic features.

A residual heat indicator, automatic switch-off and child lock are useful safety features. They don’t replace supervision while you’re cooking.

Key specifications to compare

Cooking zones and size

For one person, a student room or as an extra cooking option, a 1-ring electric hob or 2-ring electric hob may be enough. Two zones are also handy in a small kitchen, holiday home or flat.

For families, a 4-ring electric hob makes more sense. Don’t just look at the number of zones: check their diameter too. An extendable or oval zone gives you more room for a roasting tin or large pan.

Power and electrical connection

The maximum power rating determines how many zones can run on a high setting at the same time. A 2-ring model rated at 3,000 watts is compact, while 4-ring built-in models are often rated at around 6,000 to 9,300 watts. Induction models can also have a high connected load.

A higher wattage doesn’t automatically mean lower cooking costs. Energy use depends on the power setting, cooking time, pan and the way you cook. A timer with automatic switch-off can help stop a zone being left on unnecessarily.

Controls, cleaning and safety

A smooth black hob with a glass-ceramic surface is generally easy to wipe clean, but spilled sugar, salt or baked-on residue can cause scratches. Wait until the surface has cooled and don’t use an abrasive sponge.

At a minimum, look for:

  • a timer with an automatic switch-off function;
  • a child lock;
  • a residual heat indicator for each zone;
  • automatic switch-off;
  • suitable pans with a flat base;
  • clear instructions in a language you understand.

Frequently asked questions about electric hobs

Can I plug an electric hob into a standard socket?

It depends on the power rating. A portable model rated up to around 2.000 watts will often work on a single-phase connection, but always check the manual and plug type. More powerful built-in models often need a fixed or multi-phase connection. Ask a qualified installer to check the connection.

How long does a ceramic hob last?

Its lifespan depends on how it’s used, installed and maintained. Scratches, a cracked glass surface or incorrectly connected wiring can cause problems. Use flat-based cookware, lift pans rather than sliding them, and clean the hob with suitable products. Switch the appliance off and have it checked if the glass surface cracks.

How much does it cost to run an electric hob?

The cost depends on the power rating, cooking time and your energy tariff. A higher wattage can heat things more quickly, but it also uses more energy if you cook for a long time on a high setting. Use a suitably sized pan, keep a lid on it and make use of the timer to avoid unnecessary heating.
