1.      Which electric cooker installation uses zero electricity?

An electric cooker that uses zero electricity directly from the electrical grid is theoretically possible through alternative energy sources. However, it's important to note that all cooking appliances, including electric cookers, require some form of energy input to generate heat for cooking. Here are a few scenarios where you might achieve an electric cooker installation with minimal or zero reliance on grid electricity:

1. Solar-Powered Electric Cooker

  • Solar Cooker: Solar cookers utilize sunlight to generate heat for cooking without the need for electricity. These cookers often consist of reflective surfaces or solar panels that concentrate sunlight onto a cooking vessel.
  • Solar Electric Ovens: Some solar ovens are equipped with electric components for temperature control or to provide backup heating when sunlight is insufficient. However, the primary heat source is solar energy.

2. Biomass or Wood-Fired Cookers

  • Wood-Burning Stove: Traditional wood-burning stoves or biomass cookers use wood or other biomass materials as fuel to generate heat for cooking. These stoves do not require electricity for operation and are commonly used in off-grid settings.
  • Pellet Stoves: Pellet stoves can also be used for cooking and heating and operate using compressed wood pellets or other biomass materials as fuel.

3. Hybrid Electric Cookers with Alternative Energy Sources

  • Hybrid Models: Some electric cookers are designed to work in conjunction with alternative energy sources, such as solar panels or wind turbines, to minimize reliance on grid electricity. These hybrid systems may incorporate battery storage or backup generators for uninterrupted cooking during periods of low renewable energy generation.

4. Thermoelectric Cookers

  • Thermoelectric Generators: Thermoelectric cookers use the temperature difference between two surfaces to generate electricity. While not commonly used for cooking appliances due to limited power output, advancements in thermoelectric technology may lead to more efficient and practical applications in the future.


  • While these alternatives can reduce reliance on grid electricity for cooking, they may have limitations in terms of cooking capacity, convenience, and reliability compared to traditional electric cookers.
  • Depending on your location, availability of sunlight, fuel sources, and cooking needs, one of these alternatives may be more suitable for your circumstances.
  • It's essential to carefully assess the feasibility, cost, and environmental impact of any alternative energy solution before implementing it for cooking purposes. Additionally, ensure that any alternative cooker complies with safety standards and local regulations.


While achieving an electric cooker installation that uses zero electricity from the grid is challenging, alternative energy sources such as solar power, biomass, or hybrid systems offer viable options for reducing reliance on conventional electricity for cooking. These alternatives can provide environmentally friendly and sustainable solutions for off-grid or energy-efficient cooking.


2.      Why does electric cooker installation take a long time?

Electric cooker installation can sometimes take a longer time than expected due to various factors, including the complexity of the installation, necessary preparations, and scheduling considerations. Here are some reasons why electric cooker installation might take longer than anticipated:

1. Pre-Installation Preparation

  • Assessment and Planning: Before installation begins, the electrician needs to assess the kitchen layout, electrical infrastructure, and requirements for the new cooker. This initial evaluation can take time, especially if modifications or upgrades are needed.
  • Permitting Process: If permits are required for the installation, obtaining them from the local authorities can add additional time to the process.

2. Wiring and Electrical Work

  • Circuit Installation: If the kitchen does not already have a dedicated circuit for the cooker, the electrician will need to install one. This involves running new wiring from the electrical panel to the location of the cooker, which can be time-consuming, especially in older homes or complex layouts.
  • Safety Checks: Electricians must ensure that all wiring and connections meet safety standards and comply with local electrical codes. This may require additional testing and adjustments.

3. Coordination with Other Trades

  • Kitchen Renovation: If the installation is part of a larger kitchen renovation project, coordination with other tradespeople such as plumbers or carpenters may be necessary. Scheduling conflicts or delays with other contractors can impact the timeline for the electrician's work.

4. Unexpected Challenges

  • Unforeseen Issues: During installation, unexpected challenges such as hidden wiring or structural obstacles may arise, requiring additional time and effort to address.
  • Customization: If the installation requires customization or modifications to fit specific design preferences or space constraints, this can prolong the process.

5. Safety and Quality Assurance

  • Thoroughness: To ensure safety and quality, electricians may take their time to double-check all connections, verify proper grounding, and test the cooker thoroughly before completing the installation.
  • Inspections: After installation, the work may need to be inspected by local authorities to ensure compliance with building codes and regulations. Scheduling and waiting for inspections can extend the overall timeline.

6. Unexpected Events

  • Weather Delays: Inclement weather conditions such as heavy rain or snow can delay outdoor work or transportation, affecting the installation schedule.
  • Equipment or Material Availability: Delays in acquiring necessary equipment or materials can impact the installation timeline, especially if specific components need to be ordered or are back-ordered.


While electric cooker installation generally does not take an excessive amount of time, several factors can contribute to longer-than-expected timelines. These include pre-installation preparations, wiring and electrical work, coordination with other trades, unexpected challenges, safety considerations, and unforeseen events. Effective communication with your electrician, proper planning, and realistic expectations can help minimize delays and ensure a smooth installation process.

3.      Why does electric cooker installation make noise?

Electric cooker installation itself typically doesn't produce noise, as it primarily involves electrical wiring and connection work. However, once the cooker is installed and in use, there are several reasons why it might produce noise:

1. Fan Noise

  • Internal Fans: Many modern electric cookers, especially those with convection ovens or induction cooktops, are equipped with internal fans to circulate air for even cooking and to cool down components. These fans can produce noise, especially when operating at higher speeds.

2. Heating Element Noise

  • Coil Hissing: If your electric cooker uses coil heating elements, you may hear a faint hissing or crackling noise as they heat up and expand. This is typically normal and is caused by the heating element's interaction with air and food residue.

3. Induction Cooktop Noise

  • Electromagnetic Hum: Induction cooktops generate heat using electromagnetic fields, which can produce a faint humming or buzzing noise during operation. This noise is usually not very loud but may be noticeable in quiet environments.

4. Mechanical Components

  • Relay Clicking: Some electric cookers feature mechanical relays or switches that control various functions such as oven heating elements or cooktop burners. These relays may produce audible clicking sounds when turning on or off.

5. Expansion and Contraction

  • Metal Expansion: As the cooker heats up during operation, metal components may expand slightly, producing creaking or popping noises. Similarly, as the cooker cools down after use, metal components may contract, resulting in similar noises.

6. Vibration

  • Loose Parts: If any components inside the cooker become loose or improperly secured during installation or over time, they may vibrate and produce noise during operation. Checking for and tightening loose parts can help reduce this issue.

7. Airflow

  • Air Vent Noise: Air vents or exhaust fans on the cooker may produce noise as they expel hot air or steam during cooking. This noise is usually relatively quiet but may be noticeable, especially if the cooker is located in a quiet kitchen.

8. Malfunctions

  • Abnormal Sounds: While some level of noise is normal during cooker operation, excessively loud or unusual sounds may indicate a malfunction or problem with the appliance. If you notice unusual noises, it's best to have the cooker inspected by a qualified technician to identify and address any issues.


While electric cooker installation itself typically doesn't generate noise, the operation of the cooker may produce various sounds due to internal fans, heating elements, induction cooktops, mechanical components, expansion and contraction of metal, vibration, airflow, and potential malfunctions. Most of these noises are normal and not cause for concern, but if you notice any unusual or excessively loud sounds, it's advisable to have the cooker inspected by a professional technician.
