What is the gas consumption of a gas stove per hour and how to save?

Have you decided to start saving money by installing a gas meter so that you pay not according to average indicators, but for the gas actually used? Then you should calculate the gas consumption of your stove in order to select the correct gas meter for power.

How much gas does the stove consume?

Compared to a gas boiler and water heater, the stove takes so little gas that this indicator can not be taken into account at all. For example, in winter you use 500-600 cubic meters, and in summer - only 40-50 cubic meters. m. The lion's share (80-90%) of the consumption is for heating water with a column, and not for cooking on the stove. That is, your stove takes 3-5 cubic meters of gas per month. Just some minuscule thing!

But if you are going to install a meter, having only one gas stove in the household, you should definitely calculate the maximum gas consumption indicators in order to choose the right device for its metering.

How much gas does the stove take in one hour and in a month? To answer this question we need to know:

• number of burners;
• burner power of each of them;
• frequency of use of the stove by household members.

Documents for the stove usually indicate the power of the burners. Let's say you have a four-burner appliance with burners with the following power:

• one for 1 kW;
• two 1.9 kW each;
• one for 3.5 kW.

We divide the sum of the burner powers (in our case 8.30 kW) by the thermal conductivity of the gas (8-11 kWh/cubic meter) and ultimately obtain a flow rate of 0.8-1 cubic meter/hour.This, of course, is the maximum figure if all four burners work continuously! But this is exactly what we need to choose the appropriate gas meter. And he will determine how much gas actually goes into running your stove.

If you have a 2-burner or 3-burner, then the consumption will be even less.

If the stove has been in your kitchen since the time of Tsar Pea, and the documents for it are hopelessly lost somewhere, use the average data for calculations: calculate the power of the stove as 10 kW, and in the end it turns out that gas consumption will be 1.2 -2.5 cubic meters

About gas meters

Having calculated the flow rate, we can begin to select a meter model. It is very important to select it in accordance with the power of gas appliances in order to avoid inaccuracies in recording the results of the gas used. In this case, the gas meter will have to be replaced, which means additional costs for the purchase of a new meter and the installation fee.

The power index of the meter is denoted by the letter G. If you only use a stove, without a boiler and a water heater, then, knowing that your device can consume no more than 2.5 cubic meters of gas, choose a G1.6 meter, or, as a last resort, G2 .5, but no more.

If you use blue fuel to heat your home, heat water, and cook food, then problems may arise with choosing a gas meter. After all, the minimum consumption will be 0.3 cubic meters per hour (when you use only one stove), and the maximum - 7.1 cubic meters per hour (when you start heating batteries and water for washing with gas in winter). A meter with index G, capable of giving accurate readings over such a huge range, simply does not exist in nature.So, in this case, you will most likely have to install two meters of different power - separately on the boiler with a column and separately on the stove. It’s a shame, because you’ll have to pay twice for installing a gas meter, get two personal bills and pay for each of them separately.

If the house has a gas stove and a double-circuit boiler, then the power range will not be so striking, because the boiler and heater cannot work at the same time, because they have one common burner. This means that it will be possible to select a meter of appropriate power, and there will be no need to install a separate gas meter on the stove.

If you have a small family and don't cook much, replace your four-burner stove with a two- or three-burner stove. Then you can save money by purchasing a less powerful meter.

Tips for saving gas

Even if it seems that the stove consumes a tiny amount of gas, it still does not mean that you should waste blue fuel. Try to make sure that the heat does not go to waste. What is needed for this? Follow simple rules that should be memorized like “Our Father”:

• When placing a saucepan or kettle, be sure to cover the dish with a lid - this will save about 20% of gas;
• the flame level should not “climb” beyond the limits of the pan - make sure that the bottom always covers the flame area;
• Before boiling, the contents of the pan should be brought to a boil at maximum heat, since on low the walls of the pan, slowly heating up, will increase gas consumption by more than 10%;
• there should not be a working air conditioner, fan or draft from a window near the stove that can blow the flame to the side, thus increasing the flow rate by up to 15%;
• after the contents of the pan boil, the fire must be reduced as much as possible so that the liquid does not boil away;
• Try not to use the stove for preparing small portions, as the consumption will be approximately the same as for a large volume of food.

Now that you know how to calculate the gas consumption of your stove, you can easily purchase a meter for the required power. Just be sure to trust the installation to specialists.
