Short answer:<\/strong> running cost = units used x your tariff per unit. A 12 kW electric tandoor uses 12 units for each hour at full power, which is Rs 84 to Rs 132 per hour at tariffs of Rs 7 to Rs 11 per unit. In real use the heaters cycle on and off, so the average is lower. Use the worked examples below with your own tariff and hours.<\/p>\n\n

Bhai, tandoor ka bill kitna aayega? Ye sawaal har restaurant wala puchta hai. Seedha formula samajh lo, phir apne tariff se khud nikal lo.<\/p>\n\n

The formula<\/h2>\n

Units used = Power (kW) x Hours x Duty<\/strong>
Cost = Units x Tariff (Rs per unit)<\/strong><\/p>\n

Duty means the share of time the heaters are actually on. At full power it is 100% (or 1.0). While holding temperature, the controller switches the heaters on and off, so the duty is lower. We have not published a measured figure, because it depends on your set temperature, door openings and kitchen. Treat the duty in the examples as an assumption, and check your own meter to replace it.<\/p>\n\n

Cost per hour at full power (12 kW)<\/h2>\n\n\n
Tariff per unit<\/th>Cost for 1 hour at full power<\/th><\/tr><\/thead>\n
Rs 7<\/td>12 x 7 = Rs 84<\/td><\/tr>\n
Rs 9<\/td>12 x 9 = Rs 108<\/td><\/tr>\n
Rs 11<\/td>12 x 11 = Rs 132<\/td><\/tr>\n<\/tbody>\n<\/table>\n

This is the upper limit for one hour. The real figure while cooking is usually lower because of cycling.<\/p>\n\n

Example: a month of restaurant use<\/h2>\n

Assume the tandoor is used 6 hours a day for 26 days, and the heaters average 60% duty (an assumption for illustration).<\/p>\n

Units = 12 kW x 6 hours x 26 days x 0.6 = about 1,123 units<\/p>\n\n\n
Tariff per unit<\/th>Approx. monthly cost<\/th><\/tr><\/thead>\n
Rs 7<\/td>about Rs 7,860<\/td><\/tr>\n
Rs 9<\/td>about Rs 10,110<\/td><\/tr>\n
Rs 11<\/td>about Rs 12,350<\/td><\/tr>\n<\/tbody>\n<\/table>\n

Change the hours, days or duty to match your kitchen. If you run it for 3 hours a day, the cost roughly halves.<\/p>\n\n

What your bill adds on top<\/h2>\n

Commercial electricity bills usually include more than the per-unit rate: fixed or demand charges, fuel surcharges, duty and taxes. Your average cost per unit on the bill is a better number than the headline tariff. Divide your total bill by the total units used and use that figure in the formula.<\/p>\n\n

How to compare with gas<\/h2>\n

Use the same method for gas, with your own numbers:<\/p>\n

Gas cost per hour = Cylinder price \/ Hours one cylinder lasts in the tandoor<\/strong><\/p>\n

Note how long a cylinder lasts in your own service, divide the price you pay by those hours, and compare with the electric cost per hour. Gas prices change often, so we do not quote one here. Also count what is harder to put in rupees: cylinder handling and storage, temperature control, cleaner air in the kitchen and the electrical connection needed for electric. Our fuel comparison<\/a> covers the other points.<\/p>\n\n
