Enter the area, type of heating and tariff - the calculator will calculate the power, consumption and cost of heating for the season.
Gas heating is usually cheaper, but requires the installation of a boiler. Electric is simpler and does not require a chimney.
Use insulation, smart thermostats and energy-efficient heating appliances.
To calculate the cost of heating an apartment, use the calculator, indicating the area of the apartment, type of heating (centralized or individual), average temperature, duration of the heating season and energy tariff. For example, an apartment of 60 m² with central heating at a tariff of 1,800 ₽/Gcal: consumption is about 24 Gcal per season, cost is about 43,000 ₽. The calculator will automatically calculate all parameters.
To calculate the cost of heating a private house, indicate the area of the house, the type of heating (gas, electric, solid fuel), the required temperature, the length of the season and tariffs. For example, a 100 m² house with gas heating: consumption of about 2,800 m³ of gas per season at a tariff of 7 ₽/m³, cost about 20,000 ₽. The calculator takes into account the system efficiency and all factors.
To calculate heating power, use the formula: Power (W) = Area (m²) × Power per m² × Temperature coefficient. Standard power per m²: insulated house - 60-80 W/m², average thermal insulation - 90-120 W/m², old house without insulation - 130-180 W/m², apartment - 70-100 W/m². The calculator automatically calculates the required power based on building type and temperature.
To calculate energy consumption for heating, use the formula: Consumption (kWh) = (Power (W) × Operating hours × Season days) / (1000 × efficiency). For example, power 5,000 W, operation 12 hours a day, season 180 days, efficiency 100%: (5,000 × 12 × 180) / 1000 = 10,800 kWh per season. The calculator automatically calculates daily and seasonal consumption.
To calculate the cost of gas heating, determine gas consumption in m³ and multiply by the tariff. Power is calculated by area and temperature, then converted into gas consumption (1 m³ of gas ≈ 10 kW⋅h). For example, a house of 100 m², power 8,000 W, work 16 hours a day, season 200 days: consumption 28,440 kWh = 2,844 m³ of gas. At a tariff of 7 ₽/m³ the cost: 19,908 ₽ per season.
To calculate the cost of heating on the meter, record the readings at the beginning and end of the period. The difference will show consumption. For example, beginning of the season: 150 Gcal, end of the season: 174 Gcal. Consumption: 24 Gcal. At a tariff of 1,800 ₽/Gcal, the cost is: 24 × 1,800 = 43,200 ₽. The calculator helps check whether actual consumption corresponds to calculated values.
To calculate the cost of heating per month, divide the seasonal cost by the number of months in the season or multiply the daily cost by 30 days. For example, the daily cost is 290 ₽: the monthly cost is 290 × 30 = 8,700 ₽. Seasonal cost 52,272 ₽ for 6 months: monthly cost 52,272 / 6 = 8,712 ₽. The calculator shows the cost both per day and for the entire season.
To calculate the cost of heating with electricity, multiply the electricity consumption in kWh by the tariff. For example, an apartment of 50 m², power 4,400 W, operation 12 hours a day: daily consumption 52.8 kWh, seasonal consumption (180 days) 9,504 kWh. At a tariff of 5.5 ₽/kWh, the cost per season: 9,504 × 5.5 = 52,272 ₽. The calculator automatically calculates the cost for electric heating.
To calculate the cost of heating with a solid fuel boiler, determine the fuel consumption in kg and multiply by the tariff. Power is calculated by area, then converted into fuel consumption (1 kg of wood ≈ 4 kWh). For example, a house 80 m², power 8,960 W, work 14 hours a day, season 210 days: consumption 26,334 kWh = 6,583.5 kg of fuel. At a rate of 15 ₽/kg, the cost: 98,752.5 ₽ per season.
To calculate the cost of heating by area, use the power rate per m² (60-180 W/m² depending on insulation), multiply by the area to get the total power, then calculate consumption and cost. For example, area 100 m², norm 80 W/m²: power 8,000 W. When working 16 hours a day and a tariff of 5.5 ₽/kWh: daily consumption 128 kWh, cost 704 ₽/day. The calculator automatically calculates the cost by area.
To calculate the cost of heating per year, multiply the seasonal cost by the number of seasons in a year or use the annual length of the heating season. For example, the seasonal cost is 52,272 RUR for 180 days: the annual cost for one season per year is 52,272 RUR. If the season lasts all year (365 days): the cost will increase proportionally. The calculator calculates the cost for the specified period.
To calculate heating costs for a new home, consider the type of insulation and energy efficiency. A modern insulated house requires 60-80 W/m², which is significantly less than an old house (130-180 W/m²). For example, a new house of 120 m² with insulation, power 7,200 W, operation 10 hours a day: consumption of about 8,000 kWh per season. At a tariff of 5.5 ₽/kWh the cost: 44,000 ₽. The calculator takes into account the type of building when calculating.
To calculate the cost of heating according to the standard, multiply the area by the standard for thermal energy consumption (Gcal/m²) and by the tariff. For example, an apartment of 60 m², standard 0.04 Gcal/m² per month: consumption 60 × 0.04 × 6 months = 14.4 Gcal per season. At a tariff of 1,800 ₽/Gcal, the cost is 25,920 ₽. The calculator helps to compare standard and actual values.
To calculate the cost of heating for a summer residence, take into account periodic use (non-permanent residence) and the type of heating. For example, a dacha of 80 m², visits only on weekends (2 days a week), electric heating: consumption is significantly lower than for permanent residence. When working 8 hours a day, 2 days a week per season: consumption is about 2,000 kWh, cost is about 11,000 ₽. The calculator allows you to specify the number of hours of work per day.
To calculate the cost of heating with coal, determine the coal consumption in kg and multiply by the tariff. Coal has a calorific value of about 7 kWh/kg. For example, a house of 100 m², power 10,000 W, work 16 hours a day, season 200 days: consumption 32,000 kWh = 4,571 kg of coal. At a rate of 20 ₽/kg, the cost: 91,420 ₽ per season. The calculator supports calculations for solid fuel heating.
To calculate the cost of heating with wood, determine the wood consumption in m³ or kg and multiply by the tariff. Firewood has a calorific value of about 4 kWh/kg (or 1,200 kWh/m³). For example, a house 80 m², power 8,960 W, work 14 hours a day, season 210 days: consumption 26,334 kWh = 6,583.5 kg of firewood (≈ 6.6 m³). At a tariff of 3,000 ₽/m³ cost: 19,800 ₽ per season.
To calculate the cost of heating with pellets, determine the consumption of pellets in kg and multiply by the tariff. Pellets have a calorific value of about 5 kWh/kg. For example, a house of 90 m², power 9,000 W, work 15 hours a day, season 190 days: consumption 25,650 kWh = 5,130 kg of pellets. At a rate of 12 ₽/kg, the cost is 61,560 ₽ per season. The calculator calculates the cost for all types of solid fuel heating.
To calculate the cost of heating with a convector, determine the power of the convector (W), operating time and electricity tariff. For example, convector 2,000 W, operation 10 hours a day, season 180 days: consumption (2,000 × 10 × 180) / 1000 = 3,600 kWh per season. At a tariff of 5.5 ₽/kWh the cost: 19,800 ₽. For several convectors, add up the power. The calculator automatically calculates the cost for electric convectors.
To calculate the cost of heating with infrared heaters, take into account their high efficiency and the possibility of local heating. Infrared heaters require less operating time to achieve a comfortable temperature. For example, 1,500 W heater, operation 6 hours a day (instead of 12 for a convector), 180 days season: consumption (1,500 × 6 × 180) / 1000 = 1,620 kWh per season. At a tariff of 5.5 ₽/kWh, the cost is 8,910 ₽. Savings up to 50% compared to convectors.
To calculate the cost of heating with a heat pump, take into account its high coefficient of efficiency (COP) of 3-5. A heat pump consumes electricity but produces 3-5 times more heat. For example, house 100 m², power 8,000 W, COP 4: electricity consumption 8,000 / 4 = 2,000 W. When operating 12 hours a day, 200 days season: consumption (2,000 × 12 × 200) / 1000 = 4,800 kWh. At a tariff of 5.5 ₽/kWh the cost: 26,400 ₽. Savings up to 75% compared to direct electric heating.
To calculate the cost of heating with central heating, use the tariff in Gcal. For example, an apartment of 60 m², consumption of 24 Gcal per season at a tariff of 1,800 ₽/Gcal: cost 24 × 1,800 = 43,200 ₽ per season. Central heating operates around the clock during the heating season and does not require equipment maintenance. The calculator automatically calculates the cost of centralized heating.
To calculate the cost of heating taking into account insulation, use the reduced power rate per m². Insulation reduces the required power by 30-50%. For example, a 100 m² house without insulation requires 130 W/m² = 13,000 W. With insulation, the power is reduced to 80 W/m² = 8,000 W. Consumption is reduced by 38%, and the cost is correspondingly reduced. The calculator allows you to take into account the effect of insulation on the cost of heating.
To calculate the cost of heating with a programmable thermostat, take into account the reduction in operating time due to the automatic reduction of temperature in the absence of people. Programmable thermostats can reduce costs by 15-25%. For example, conventional heating: work 12 hours a day, cost 52,272 ₽ per season. With thermostat: work 9 hours a day (25% reduction), cost 39,204 ₽. Saving RUB 13,068 per season. The calculator helps you estimate the savings from using a thermostat.
To calculate the cost of heating for an apartment building, multiply the cost per apartment by the number of apartments. For example, an apartment of 60 m², cost 43,200 ₽ per season. House with 100 apartments: total cost 100 × 43,200 = 4,320,000 RUR per season. The calculator helps you calculate the cost for individual apartments; summarize the results for the entire house.
To calculate the cost of heating using a two-tariff meter, divide consumption into daytime and nighttime, multiply by the corresponding tariffs. For example, consumption of 10,800 kWh per season: daytime 6,480 kWh (tariff 6 ₽/kWh), nighttime 4,320 kWh (tariff 2.5 ₽/kWh). Cost: 6,480 × 6 + 4,320 × 2.5 = 38,880 + 10,800 = 49,680 ₽. With a single tariff meter (5.5 ₽/kWh): 59,400 ₽. Savings of about 16%. The calculator allows you to specify a single-tariff or two-tariff mode.
To calculate the cost of heating for a commercial premises, take into account the operating mode (working days, weekends), area and type of heating. For example, an office of 200 m², work only on weekdays (5 days a week, 8 hours a day), electric heating: consumption is significantly lower than with round-the-clock heating. With a power of 16,000 W, operation 8 hours a day, 5 days a week per season: consumption is about 5,000 kWh, cost is about 27,500 ₽. The calculator allows you to specify the number of hours of work per day.
To calculate the cost of heating for a production workshop, take into account the large area, ceiling height and possible technological heat release. Industrial premises require more power per m² due to high ceilings and large volumes. For example, a workshop of 500 m² with a ceiling height of 6 m (volume 3,000 m³): power approximately 150 W/m² = 75,000 W. When working 16 hours a day, season 180 days: consumption about 216,000 kWh, cost about 1,188,000 ₽. The calculator helps calculate the cost for industrial premises.
