Kitchen Chimney Power Consumption & Correct Installation Height – Complete Guide for Indian Homes

Complete guide

A kitchen chimney has become an important appliance in modern Indian kitchens. It helps remove smoke, oil particles, grease, heat and cooking odours, especially when preparing fried foods, curries, dosa, chapati and other dishes that generate smoke and oil vapour.

However, customers commonly have two important questions before purchasing a chimney:

How much electricity does a kitchen chimney consume?
What should be the correct distance between the gas stove and chimney?

Both are important because choosing an energy-efficient chimney and installing it at the correct height can improve suction performance, safety and overall user experience.

How Much Electricity Does a Kitchen Chimney Consume?

The good news is that a kitchen chimney is generally not a high-electricity-consuming appliance compared with appliances such as an air conditioner, water heater or electric oven.

Most household chimneys operate on normal residential electrical supply. For example, several current chimney specifications list 230V, 50Hz, single-phase AC, while individual power consumption varies depending on the motor, lighting, speed and features of the model.

The total electrical load mainly comes from:

• Chimney motor
• LED lights
• Touch/gesture control electronics
• Auto-clean heater, when activated
• Sensors or other smart functions in selected models

As a practical example, a chimney rated at around 200–250 watts running for one hour would consume approximately 0.20–0.25 kWh (units) of electricity.

If such a chimney is operated for about 2 hours every day, the approximate consumption could be:

0.25 kW × 2 hours × 30 days = 15 units per month

Actual consumption can be lower or higher depending on the model and speed used. , for example, that the electricity consumption depends on the individual model and notes that many models consume approximately 1 unit for every 3–4 hours of operation.

Therefore, customers should always check the specific model’s rated power rather than assuming that every chimney consumes the same electricity.

Does Higher Suction Mean Much Higher Electricity Consumption?

Not necessarily.

Chimney suction capacity is normally expressed in m³/hr, such as:

1200 m³/hr, 1400 m³/hr, 1500 m³/hr or 1800 m³/hr.

This indicates the volume of air the chimney can move in an hour; it is not the same thing as electrical wattage.

Modern motors, particularly BLDC motors, can provide strong airflow while being designed for improved energy efficiency.

For example,currently listed  BLDC chimney models with suction capacities around 1500 m³/hr, while its chimney specifications commonly use a 230V, 50Hz single-phase supply.

So when selecting a chimney, customers should consider suction capacity, motor technology, kitchen size, cooking style and power consumption together.

What Is the Correct Height Between a Chimney and Gas Stove?

Installation height is one of the most important factors affecting chimney performance.

For a conventional wall-mounted chimney above a gas stove, a commonly recommended distance is approximately:

Gas Stove – Around 75 cm

Most brands specifies a minimum safety distance of 750 mm (75 cm) for gas burners and 650 mm (65 cm) for electric cookers for applicable hood designs.

This distance should generally be measured from the top cooking surface/burner area to the lowest part of the chimney hood.

However, installation requirements can differ according to chimney design. For example, vertical/slant hoods may have different permitted distances. Therefore, the installation manual supplied with the exact chimney model must always take priority.

Why Is Correct Chimney Height So Important?

A chimney works by capturing smoke, steam, oil vapour and odours as they rise from cooking.

If the chimney is installed too high, the smoke has more opportunity to spread sideways into the kitchen before entering the chimney’s effective suction area. This can reduce extraction performance. It is specifically notes that considerably exceeding the recommended mounting height can reduce extraction power.

Customers may then feel:

“My chimney has 1200 or 1500 m³/hr suction, but smoke is still entering the kitchen.”

The problem may not necessarily be the motor. Incorrect installation height, poor ducting or incorrect chimney width can also reduce practical performance.

What Happens If the Chimney Is Installed Too Low?

Installing the chimney very close to a gas flame is also not recommended.

A chimney positioned too low can create safety  problems. It may interfere with large vessels and make the cooking area uncomfortable. More importantly, sufficient clearance is required between the gas flame and chimney.

This is why the manufacturer’s specified minimum safety distance should always be followed.

The objective is not simply to install the chimney as low as possible for better suction. The objective is to find the correct balance between safety, cooking clearance and effective smoke capture.

Chimney Width Is Also Important

Correct height alone will not provide the best results if the chimney is too narrow for the cooking area.

The chimney should ideally be the same width as or wider than the hob/cooktop. brands advises that the kitchen hood should be the same size as or larger than the hob or cooktop.

For example:

60 cm chimney – generally suitable where the burner area comfortably fits within approximately 60 cm.

90 cm chimney – preferable for wider cooking surfaces and many 3-burner or 4-burner stove arrangements where burners are spread across a larger area.

The important point is not simply the number of burners. The chimney should cover the effective cooking area.

If the burner area extends beyond the chimney width, smoke from the outer burners can escape around the sides.

Ducting Also Affects Chimney Performance

Even a powerful chimney can perform poorly when the ducting is badly designed.

For better extraction, the duct should be:

• As short as practically possible
• As straight as possible
• Installed with minimum bends
• Properly sized according to the chimney outlet
• Free from unnecessary reductions in pipe diameter

Elica notes that bends, angles and excessive connections can reduce extraction airflow. It also states that larger ducting can improve performance and that its 90 cm chimney/decorative hoods generally use 150 mm air outlets.

Therefore, customers should not judge chimney performance only by the advertised suction number.

Correct chimney + correct width + correct installation height + proper ducting = better real-world performance.

Recommended Setup for an Average Indian Household

For a typical family using the kitchen every day, choose a chimney based on the stove width, cooking habits and kitchen conditions.

For Indian cooking involving regular frying, tadka, masala and oil-based cooking, good suction capacity is useful. A correctly selected 60 cm, 75 cm or 90 cm chimney with suitable suction can keep the kitchen cleaner and more comfortable.

The electrical supply should also have proper earthing. It recommends proper earthing and specifies an appropriate electrical point for kitchen hoods.

Simple Example

Suppose a family uses its chimney:

Morning: 45 minutes
Afternoon: 30 minutes
Night: 45 minutes

Total usage = approximately 2 hours per day.

If the chimney averages 200 watts during operation:

200W × 2 hours = 400Wh = 0.4 units per day

For 30 days:

0.4 × 30 = approximately 12 units per month

This is only an illustration. Actual electricity consumption will vary significantly depending on chimney wattage, selected speed, lighting, auto-clean operation and daily usage.

Final Conclusion

A kitchen chimney is generally a relatively modest electricity consumer, but customers should always check the wattage of the individual model before calculating monthly power consumption.

Installation is equally important. For many conventional chimney designs, a useful reference is approximately 75 cm above a gas cooktop and 65 cm above an electric cooktop, subject to the manufacturer’s installation instructions for the exact model.

Installing the chimney too high can reduce smoke capture, while installing it too low can affect safety and cooking convenience.

At LG Shopnest, we recommend customers consider these four important factors before selecting and installing a kitchen chimney:

Choose the correct chimney width → Maintain the recommended installation height → Use proper ducting → Select suitable suction capacity.

Based on our experience with kitchen appliances, we believe that choosing the right chimney is not only about higher suction power. The chimney size should properly cover your cooking area, the installation height should follow the manufacturer’s recommendation, and the ducting should be planned correctly for efficient airflow.

When these factors are properly considered, your kitchen chimney can remove smoke, oil vapour, grease and cooking odours more effectively, helping to keep your kitchen walls, cabinets and cooking area cleaner.

LG Shopnest Tip: Before purchasing a chimney, consider your stove or hob size, number and position of burners, kitchen size and cooking habits. Choosing the right chimney and installing it correctly can provide better performance, easier maintenance and a more comfortable cooking experience for years.
