Boiler how many kilowatts per hour

How much electricity and money a boiler will consume

Electricity is the most expensive energy carrier, but how ordinary boiler will devastate the ? The costs will directly depend on how much hot water we will consume, and what is its temperature How much expenses for a boiler (storage water heater) are obtained on average per family? How to save when using a boiler, and which one will be the most profitable?

What volume of hot water is consumed per day and for a month? From what temperature to which we will warm?

Take average data: hot water consumption per day. 100 liters (3000 liters per month), its temperature is 60 degrees, cold temperature is 10 degrees.

To calculate the energy consumption for water heating, we will use the simplest empirical formula. W = 0.00116 V (T2 –T1), where V is volume, 100 liters, T2. final temperature, 60 degrees, T1. initial temperature, 10 degrees. We get w = 0.00116 100 (60-10) = 5.8 kW per day, or 174 kW per month.

HOW TO CALCULATE BOILER CAPACITY

But part of the energy from the boiler is transmitted to the air when cooling, while the water heater will turn on and maintain the temperature at a given level It is believed that the modern storage water heater gives an average of no more than 0.5 kW for a day heating per day. Then the daily electricity consumption for water heating will be 5.80.5 = 6.3 kW, and 189 kW for a month.

The figures of this count in the end are not so small. It turns out that you need to pay for electricity almost 1000 in one month, with a tariff of about 5 /kWh. And this is only for one boiler, not taking into account another energy consumption.

In reality, the operation of the boiler in 90% of cases is more economical than according to the standard calculation given here. How to reduce the cost of a water heater?

How much in reality the accumulative water heater consumes energy

Only statistics can give real numbers, and not alleged data on consumption and temperature. What they save when using a boiler?

Typically, the water temperature is much lower than 60 degrees. After all, such heating is very hot, suitable for taking a bath, and from the tap. will be burned. It is not needed to wash plates If the soul is not planned, then the stringing householders warm up to only 20. 25 degrees. Cool water is quite comfortable in the kitchen.

The real consumption of hot water for the family, with a very economical approach, is very small. about 30 liters of water at 20 degrees (heating by 10 degrees). and this is all a day. If there is a receiving shower. about 10 liters of 45 degrees per person. total 30 liters, plus 20 liters for other expenses.

And only the adoption of the bath entails serious heating and consumption

  • In general, with very economical operation, it turns out only no more than 50 kW per month for a boiler.
  • With moderate economy. about 100 kW per month for a boiler, and, accordingly, 500.

How to conduct calculations?

  • T1. initial water temperature in the boiler.
  • T2. heated water.
  • V. tank capacity in liters.
  • W is the power of the heating element in kilowatts.
  • The initial temperature is equal to. 10 o.
  • Heated. 60 o C.
  • The capacity contains 50 liters.
  • The electric heating device has a power of 1.5 kW.
  • Energy, which was determined earlier, is 2.9 kW.
  • For heating, a storage water heater is used for 50 liters.
  • Given all the reproduced actions during the day, the water heated in the boiler is carried out about 4 times.
  • It is known that the average daily consumption of hot water for the family is 150 liters. Based on this, it turns out: 15030 = 4.5m3
  • According to the tariff, for water is paid 30 for 1m3. So: 4.530 = 135.

Flowing or accumulative. who has more consumption?

Having analyzed these two opposite situations, we can conclude that for heating water in large volumes and servicing several points at the same time, it is more profitable to purchase a storage type, and for short.term use, it is better to stop your choice on a firm water heater.

Convection heater

Convection heater. is considered one of the safest heaters, the principle of operation of the convection heater mixing and circulation of the air layers, the grate is located at the bottom of the convector through which the air enters, the already heated air comes out through the holes. The convector provides protection against overturning, from overheating, this type of heater can be hung for convenience on the wall, it has a flat shape and a small size.

Infrared heater. the principle of operation of such a heater is based on infrared radiation, which heats various objects into the room, and the objects already heat the air, this is the most natural way to heat the air. Oxygen burnability, unlike other models of heaters, is much lower than.

Each type of heater has its own recommended room volume for its full heating.

Which affects the consumption of electricity by the heater?

The main characteristic by which you can determine how much the heater will be windpoint is the power consumption of the device. The higher it is, the accordingly there will be an electricity consumption. It is also worth noting that consumption depends on the regime in which it works.

Convection heaters mainly have 750 W energy consumption, 1 kilowatts, 1,500 watts 2 kW can be more.For heat-tollers, consumption is 1,500-2000 watts per hour.For oils, also limits from 1000 to 2000 watts/hour.

How much Natural gas is required to produce 1 Ton of steam.

Let’s calculate how much electricity the heater will spend if it works at full capacity of 2000 watts.Total we get 2 kW per hour. If we take that in winter the heater heating for an hour is resting 2 rest, we get 8 hours of work.

28 = 16 kW per day, and if you take the average price for 1 kW of electricity 4, we get 164 = 64 per day.The numbers can be less if you initially use a couple of hours for the full and then use less consumption mode to maintain temperature.

Based on the data received during the calculations, you can calculate how many electricity the heater will consume in 1 month and for the entire period of cold weather.

Thus, in order to determine how much electricity consumes the heater, it is enough to know its power consumed in the absence of operating modes, and ate there are heating modes to know how much everyone consumes electricity.

How much heat the boiler loses?

If you are considering a specific boiler model, look into its specification, instructions or guidance. Heat loss should be indicated there. The manufacturer can indicate them as a percentage per hour, kilowatts per hour for full volume, percent per day and kilowatts per day for the entire capacity.

If heat loss is indicated as a percentage per hour, follow the formula:

W1 = W X (p x 24 100) / 100

When heat losses are indicated as a percentage per day, the formula is this:

With heat loss in kilowatts in one hour:

boiler, many, kilowatts, hour

W1 = P X 24 W

If the heat loss in kilowatts per day is indicated:

  • W is the amount of electricity. necessary for water heating;
  • P. heat loss in kilowatts or percent;
  • W1. the amount of electricity in kilowatts. Which consumes a boiler a day.

Just substitute all the known data and you will find out how much your boiler wraps up per day. Multiply this number by 30, and you will receive electricity consumption to heating water in a month.

By the same technique, you can find out how much electricity is consumed by a flowing water heater. But for him it will not be necessary to consider heat loss, because he does not have a large supply of water. He does not need to spend electricity on maintaining its temperature.

An example of calculating the boiler consumption

Suppose there is a boiler with heat loss 0.5% per hour, and a day for the family is required for 200 liters of water. Cold water temperature is 10 and hot 55 degrees. From here we have:

We will substitute these values ​​in the first formula:

W = 0.0016 x 200 x (55. 10) = 14.four

It turns out that you need 14 to heat water.4 kilowatts per day, or 432 per month.

Now let’s take into account heat loss. We already know the number W, and P will be 0.5. We substitute values ​​in the formula and get:

W1 = 14.4 x (0.5 x 24 100) / 100 = 16.128

This means that the average daily consumption of electricity by the water heater is 16.128 kW, and for a month. 483.84 kW.

Consumption

The costs of paying electricity consumes on how much electricity consumes the water heater. There are three types of heating equipment and each of the options has its own characteristics:

  • Accumulative water heater. Is a tank of different volumes, with a heater inside. Water heats up to a certain temperature, after which the heater is turned off. Control over the process is performed by a special sensor. When the temperature decreases, below set, the heater turns on and brings the temperature to the required. This leads to an overrun of electricity, if you do not use the heated water in time and do not turn off the device. The assortment of electric heaters with the heater is quite extensive.
  • Empty water heater. The device has no tank. Water moves through pipes, enters the heater. Passing through it, water reaches the required temperature. How much such a water heater consumes, it will depend on the temperature of the water at the input.
  • Indirect water heater. Water heating in the tank is carried out due to the heating system. It can be a central heating or gas boiler. Thanks to the functional features of the boiler, the water in the heater remains hot, even after disconnecting the main heat source. Thanks to an additional thermal insulation system, the volumes consumed by an indirect heating boiler are very insignificant: due to indirect use of electricity, significant savings in the means are noted.

Through calculations and observations, it was found that a prototing type of devices consume a larger amount of electricity, since they have a greater power. But on the other hand, flowing systems are included periodically, while the accumulative are constantly used. The power of the accumulative water heater is different, so they cannot be called completely energy.saving.

Do not spend a lot and choose the right heating device, it is possible if you find out how much energy the boiler consumes per day.

To make calculations, you need to know the following indicators: the capacity of the water heater, the power of the device, the water consumption, the time required to heat water to the desired temperature and the power consumption of the device in watts.

How much electricity does the air conditioner consume

There are approximate tables that allow you to estimate what volume of the tank will be required for comfortable use. For example, it is enough for one person to install a water heater with a volume of ten to thirty liters, while the first number is the minimum volume, the latter is normal. For a family of two people, you need a fifty liter boiler. A classic family of two adults and two children needs a water heater with a volume of one hundred to twenty liters.

Experts recommend on average to count on one person fifty liters of water per day. It is worth noting that the numbers can be much lower or higher. It all depends on the needs for the use of water: cooking, compliance with personal hygiene, washing, washing dishes, taking a bath or shower. There are established norms of water consumption per person: for a day for washing, about eighty liters are needed, about twenty liters for washing dishes, bathing in the bathroom. about one hundred eighty liters.

boiler, many, kilowatts, hour

But when buying, not only litting is taken into account. Since cold and hot water is mixed, the consumption is less.

How much electricity consumes the average boiler?

Technical documentation is attached to the water heater, which indicates all equipment values. To calculate electricity, take the average value. To do this, you need the following values:

  • The amount of kilowatts that the water heater spent during heating and maintaining water temperature;
  • The volume of hot water spent a day in liters or cubic meters.

Consider an example for a 50 liter boiler. First of all, it should be determined how long the water is heated in the water heater. The minimum temperature is usually 70 ° C. In order to heat water to the desired temperature, about 2 hours are spent. To maintain a comfortable temperature, the heating cycle occurs 2 times a day for 2 hours. The technical documentation shall indicate the consumption of electricity in the working mode: 2 kW per hour. Based on the calculation, we get 4 kW per day.

In addition, do not forget about the “Heating” mode. 4 kW is required to be divided into the number of hours that do not participate in the heating of the water. Thus, 4 kW/12 = 0.3 kW per day. The total amount of electricity consumed by a 50 liter boiler: 40.3 = 4.3 kW. 129 kW is spent in 30 days. To calculate the cost of payment, you need to know tariffs for each region.

How to save?

It is unreasonable to completely abandon the benefits of modern life, but in order to save money you can pay attention to energy.saving refrigerators, because this device will operate all year round, regardless of weather conditions. If you calculate how much energy is consuming a TV and a computer per month, you can fully affect this amount, choosing one working device. Often the monitor turned on all day without benefit, and the working TV becomes a background under which we do everyday business. It’s not easy to get rid of such habits, but in a month this will give a result in the form of a reduced account for electricity.

  • Replace all lighting devices with new energy.saving or LED lamps. The initial attachment of a hundredths pay off with serious savings and a long service life.
  • If you often use an electric kettle, always pour water exactly as much as necessary, and not in reserve. Unfortunately, energy.saving dummies have not yet been invented, but to adjust the use mode is quite in your strength.
  • Put the computer into a comfortable waiting mode. In this case, it turns off automatically if it passes for a certain time in inaction. When turned on, it will cost less energy, which is also important.
  • Defrosting the refrigerator and freezer in time. also part of family savings. When forming a significant amount of ice on the walls, the electricity consumption increases, so be sure to eliminate this factor.
  • The use of heat.reflecting screens will help make the operation of heaters and convectors more efficiently.
  • Replacing the wiring and the organization of local lighting in the kitchen or in the recreation area will also significantly reduce costs.
  • The use of adapters and extension cords increases energy consumption.
  • By acquiring new electrical appliances, it is better to give preference to the economical class of consumption. The main positions are given in the table.

What Size Heat Pump/Boiler Do I Need? | Heat Loss CHEAT SHEET | Consumer Advice

One of the unexplored methods of saving electricity is the installation of multi.tariff meters. This will include some devices at night, when electricity will cost cheaper. This practice has shown itself perfectly in foreign countries, but unfortunately, until we have taken root.

It is probably impossible to completely abandon the use of electrical appliances in the modern world. Even a gas boiler and heating convector must consume a certain amount of energy for their functioning. If we are talking about a welding machine, boiler or air conditioning, consumption is significant even with short use. Despite this, the consumer buys more and more diverse electrical appliances, so it will be useful to find out the main “culprit” of electricity accounts, as well as proven methods of reasonable savings that will help make costs less.

Calculations of electricity consumption by the heater

Let’s look at the case of a convector with a capacity of 2000 watts. To begin with, on such a heater, it is necessary to set the air temperature that the convector must support, for example, 25 s. After supplying to the electricity heater, it will work for heating in full power mode, t.E 2000 watts., And in this mode, the convector will work until then (suppose for 20 minutes), until the air temperature is reached, which was set initially, in our case it is 25s. After that, the temperature control system and the supply of electricity to the heating element will stop, which means that the consumption of electricity will cease.

Boilers with a capacity of 50 liters

Take three devices for 50 liters with different parameters and calculate their effectiveness. For everyone, we take the temperature of the water in the tap of 15 degrees, and the hot 60 degrees. Day consumption will be 200 liters.

Electricity consumption

The amount of electricity

How many kilowatts does a boiler consume a month? This should be known to those who have already installed the heater or is only going to do it.

The consumption of electricity for heating water depends on many factors:

  • Cold water temperatures entering the heater.
  • Water heaters.
  • Water consumption per day.
  • The temperature indicator of hot water at the output.

The average temperature of cold water before entering the water heater ranges from within five to ten degrees. The average boiler heat loss is within 0.007. 0, 0011 kW per liter of water. To find out how much water will be consumed per day, you need to divide hot water into the amount of days in a month.

Despite the desire to save, experts do not advise heating water in Boyler below fifty.five degrees. Often a repulsive smell appears. This is due to the fact that pathogenic microflora may develop in the liquid, this will negatively affect the state of health.

Accumulative water heater

In standby mode, the water heater also consumes electricity, it is aimed at compensation for heat loss. In the technical passport, the size of heat loss is indicated for each boiler model. They can be indicated as a percentage, kilowatts.

boiler, many, kilowatts, hour

How much electricity does the air conditioner consume

Let’s try to calculate the approximate electricity consumption by boiler. For example, the heat loss of equipment is half a percent per hour. Imagine that two hundred liters of water are needed for the family. The temperature of cold water at the entrance is ten degrees, and at the exit. fifty.five.

To find out how much kW is consuming a boiler, you should make simple calculations. It is generally accepted that for heating water one degree required 1.16 W. The formula that allows you to calculate the consumption of electricity is simple: it is necessary to multiply 0.0016 kilowatts by the amount of hot water per day and multiply by the difference in water at the outlet of cold water at the input. The obtained indicators are the amount of kilowatts necessary for heating water.

We get such a result with our example. 14.4 kW. This is the number of consumed kilowatts per day. To count the consumption of the resource per month, gently, the amount of spent in one day, multiply by thirty. It will turn out four hundred and thirty.two kilowatts per month. The calculation, taking into account the heat loss equal to 0.5, will give the following result: the consumption of kilowatts per day is 16, 13 kW. Multiplying the number by the number of days in the month, we get the final result.

Now let’s try to calculate how much the flow heater consumes.

This variant of the heater is recommended for installation mainly for household needs.

The running heaters join the mixer directly, do not depend on water pressure in the central pipeline. It is worth noting that the water at the output does not always satisfy the requests. The documentation for the heater most often indicates the temperature that needs to be summarized with the input indicators. Consumption depends on the frequency and intensity of the use of the heater. With moderate use, consumption does not exceed one hundred kilowatts per month.

Let’s summarize. To calculate the consumption of electricity of the accumulative water heater, it is important to get the following information:

  • Find out how much water is consumed daily.
  • Find out how much electricity is consumed by the device for an hour of operation.
  • Make mathematical calculations by multiplying the results by the number of days in a month.

It should be remembered that electricity consumption in different devices may vary significantly. The frequency and intensity of the use of heating equipment will affect the size of energy consumption.

Reduce the amount of payment for electricity can and should be necessary.

Castle heater.

There are a number of recommendations that help adjust the costs.

  • Find out how much time the boiler needs to cool. Provided that you are absent at home, this period of time and longer, it is advisable to drain the water and turn off the device.
  • Check the thermal insulation of the device case. If the top of the water heater is warm, it has errors in insulation. Additional thermal insulation should be installed.
  • The installation of an indirect heater will help to save significantly on payment of electricity. The water will warm up from the heating system and go to the boiler is already warm.
  • If the water heater is equipped with a timer and a controller, program it to turn it on for a certain time until your return and shutdown for the duration of the absence.
  • Control the condition of the heating element. If it has a plaque plaque, the effectiveness of the device is reduced, and the consumption of electricity increases significantly.

How much energy is consumed by water heaters

Interruptions with the supply of centralized hot water ceased to be a problem, since its absence compensated for the appearance of electric water heaters. If there is such a device in a house or apartment, disconnecting hot water does not cause any concern and trouble. But, when planning the acquisition of such technology, it is important to pay attention not only to design and cost, but also to take into account energy consumption. It is it that will affect the cost of electricity. When buying a water heater, the consumption will increase and this is undoubtedly, but you can try to make it minimal by choosing the water heater correctly. Everything is taken into account: the volume of the device, the power of the boiler, the technical characteristics. Let’s try to calculate how much electricity is consumed by a boiler, how to make the use of the device cheaper.
