How to refuse centralized hot water? How to refuse hot water.

Ecology of consumption. House: How to abandon the city hot water system, while not only forever forgetting about weak water heating, but also doing it as economically as possible. This article will reveal some of the pitfalls of such a transition and provide a real payback calculation.

Why you should abandon the city hot water supply

Urban DHW system known to many for its sad quality of services. Using it not only often costs a pretty penny, in many apartments water is supplied undercooled to established norms and its temperature practically does not rise above 40–50 °С. To this must be added a few weeks of absence hot water during the summer planned shutdowns, when the owners are forced to heat water for domestic and sanitary needs using literally improvised methods.

There is an alternative: refuse to supply hot water to the apartment and heat it yourself using an electric or gas water heater. At the same time, interventions in rough plumbing are minimal, most appliances have the simplest circuit strapping and can be installed even after finishing work is completed.

What is to be done:

1. Contact the ESO or the housing and communal services with a request to disconnect from the municipal DHW system. If it is possible for the project of the house, get the specifications.

2. Install the water heater and tie it.

3. Provide for the possibility of installing seals on each branch of each of the DHW risers. The best option- plugs with loops for sealing.

4. In the presence of the inspector, draw up an act on the shutdown and the presence of a visible rupture of the pipeline.

Why is it considered saving

Benefits of Going Self-Sufficient hot water seems obvious, given that the cost of one cubic meter includes total losses heat throughout the system. For example, consider special case for small apartment in the Moscow region. As of July 2015, tariffs for the region for public utilities such:

A family of four consumes an average of 16 m 3 hot water, that is, pays 1933.12 rubles for city hot water supply. per month. The cost of the water itself in the DHW tariff is 493.92 rubles, the remaining 1439.20 rubles. is the cost of heating 16 m 3 water up to 50 ° C, that is, 89 rubles. 95 kop. for 1 m 3 .

As you can see, water heating installations in the city system are not very economical, because 17.9 kW of electricity is spent on heating one cubic meter at a single rate or 14.9 m 3 natural gas.

Payback period

But will they Appliances economical enough to pay for itself in a foreseeable time? For the family of 4 mentioned above, about 500 liters of hot water per day are needed. This task is within the power of a pressurized instantaneous water heater with a power of 6–6.5 kW or a storage heater of 120 liters with buffer capacity and total power Heating elements up to 3 kW.

A good and reliable storage heater will cost about 10,000–20,000 rubles, and a flow heater will cost 15,000–30,000 rubles. It will be somewhat more difficult to install a flow-through one, since everything that has an electric power above 3 kW must be connected with a separate cable with a core cross section of 4 mm 2 or more with the obligatory organization protective earth and shutdowns, and this is an additional 3500 rubles. For the boiler, you only need a differential machine worth 1400 rubles. and a regular socket on a separate protective group.

As for the plumbing piping, it is the same for both devices. Since the water heater can be inserted into almost any point of the hot and cold water pipes, you will need a kit to connect it stop valves and 6–8 meters of pipe, which will cost another 3,000 rubles. In total, the cost of instantaneous water heater and its installation will amount to 35,500 rubles, and the accumulative one will pull 30,400 rubles.

An example of connecting a storage water heater: 1 - inlet valve cold water; 2 - safety valve; 3 - drain valve; 4 - valve for air when draining water; 5 - storage water heater; 6 - differential machine; 7 - to the shield; 8 - water to consumers

A storage water heater with a volume of 120 liters with a power of 2 kW spends 2 hours to heat water up to 50 degrees. To heat 1 m 3, he will need 1000 / 120 x 2 x 2 \u003d 33.33 kWh. That is, for self-sufficiency it is necessary that average cost electricity for the operation of the water heater was less than 2.70 rubles.

Flow heater at bandwidth 3 l / min per hour will heat 180 liters of water, spending 8 kWh on this. That is, its electricity consumption is about 30% higher. It can be argued that the storage water heater consumes energy not only for direct heating, but also for maintaining the temperature, however, these are short-term inclusions and such an amendment can be neglected.

Really economical in this respect only gas water heaters And they are cheaper than electric ones. With a power of 24 kW and a flow of 14 l / min, the column will warm up a cubic meter of water to 70-80 ° C in about 70 minutes, spending less than three cubic meters of gas on it.

So which water heater to choose

If it is possible to install a gas heater in the apartment project, this is exactly what you need to do. Even five thousand rubles a month for hot water supply is not money, while the water is at a stable temperature, under good pressure and in full. No electric heater can do this.

If the house is not gasified, which in modern construction happens more and more frequently electric water heaters can't be avoided. Yes, a small overpayment on the face, but how much more comfortable life becomes! Moreover, you can not spend money on an expensive heater, but install a cheaper one.

The highest water consumption is observed in the evening and at night, when the electricity tariff is 4.63 and 1.43 rubles. for 1 kW. The average daily cost of a kilowatt for DHW operation- about 1.8 rubles. And at such a cost, the price of electric hot water supply is quite comparable to the city. At least hot water is not more expensive, and the whole system is reliable and durable. The most economical in this case are storage water heaters of large volume, connected through a contactor with a timer for operation only in the night and semi-peak daily zones. Their payback period is usually about 3 years, flow-through ones will pay off in 5-7 years. If water is supplied to the house unheated, then the payback period will be significantly reduced, because the consumption of hot water will decrease significantly.

Water Heater Placement Tips

Heaters, with the exception of non-pressure flow heaters, are prohibited from being placed in the bathroom due to electrical safety requirements. So the best place for accumulative water heaters - this is a toilet, and for pressure flow - a kitchen or a niche of a kitchen set.

In both places there is a supply of both cold and hot water, pipes can be easily cut even with tees at the connection point kitchen sink. Do not forget that the storage water heater must be supplied check valve, and flow - with a mesh filter.published

Hot water is one of the benefits of civilization. But, unfortunately, very often city dwellers are faced with the fact that such, that is, really hot, it is difficult to call it.

Many put up with this, not wanting conflicts and litigation with management companies, city utilities, someone is waiting for the situation to improve. But every year everything large quantity citizens want to change the situation radically, they begin to figure out how to refuse hot water, which would be more correctly called warm, so as not to pay quite a lot of money for the underdelivery of services.

Hot water is one of the benefits of civilization

enjoy hot centralized water supply becomes for many not only expensive, but also unreasonable business. Indeed, most often the temperature of the liquid flowing from the tap with a red label does not rise above 40 degrees. And if we also remember regular blackouts (some for the whole summer, some for two weeks) during the period repair work, then the expediency of the service becomes even more questionable.

Most often, the temperature of the liquid flowing from the tap with a red label does not rise above 40 degrees

So thinking tenants are looking for an alternative, how to provide themselves with real boiling water. And they find it ... in individual water heaters powered by electricity or gas, discovering the simplest ways of installation, piping almost anywhere in the apartment, at any stage of repair and finishing work. Let's look at this option step by step.

If you are not satisfied with the quality of the service, the answer to the question of how to refuse hot water will fit into 5 standard steps:

• making a conscious decision to refuse centralized hot water;
• appeal to the housing and communal services or ESO with a statement to turn off hot water, clarify technical feasibility;

Appeal to the housing and communal services or ESO with a statement to turn off hot water, ascertaining the technical feasibility

• if possible, the choice and purchase of a water heater suitable model, its installation, strapping;
• thinking over the installation of plugs, sealing loops;

Call a plumber to seal the plugs

• calling technicians and an inspector who will install, seal the plugs, draw up an act.

Now you know how to give up warm water instead of hot. The algorithm of actions may be somewhat modified in each specific case. But the main thing here will still be life without “state” hot water, since now you will be independently responsible for having it in the apartment.

Life after a shutdown in numbers: will the boiler pay off

For calculations, let's take an ordinary family of four, which requires about 500 liters of boiling water per day. When choosing a heater, there are two options: storage or flow. 500 liters of flow can be heated at a power of 6.5 kilowatts. The accumulative one with a capacity of up to 120 liters will cope with its task with a power of 3 kilowatts.

Attention! The storage boiler is cheaper - from 10 to 20 thousand rubles, and it is much easier to install it.

A flow heater costs from 15 to 30 thousand, plus additional installation costs of about 4 thousand rubles.

A storage device with an average power of 2 kilowatts will heat 120 liters for two hours

Why is the flow is more difficult to install? Because its power is higher than 3 kilowatts, and it needs a separate cable, protective earth, disconnection. The drive, on the other hand, needs its own differential-type machine plus a socket installed on a personal protective group. And these are expenses in the amount of not more than 1400 rubles. Both types of devices are tied in approximately the same way. They crash into the cold water supply system. This requires shut-off valves and pipes (6-8 meters), which will cost 3,000 rubles. Total: storage boiler(purchase + installation) - 30,400 rubles, flow heater- 35,500. Now, knowing how to refuse hot water, and the starting cost of failure, let's move on to payback.

A storage device with an average power of 2 kilowatts will heat 120 liters for two hours. By simple calculations, it becomes clear that for one cubic meter he will need a little more than 33 kilowatts per hour. Therefore, for payback, it is necessary that electricity cost about 2 rubles. 70 kop. Here, many will still remember its inclusion in the heating of water. But the energy consumption at these moments is more than insignificant, so you should not count them.

Flow boiler heats 180 liters per hour, spending 8 kilowatts on it

The throughput of the flow device is 3 liters of boiling water per minute. It heats 180 liters per hour, spending 8 kilowatts on it. I.e electrical energy he will need more than 30%. After analyzing the above, many understand that a gas-powered heating device will be cheaper here. Let's start with the fact that such units are several times cheaper than electric ones, having a power of 24 kilowatts. They heat (with the flow method) 14 liters per minute to a temperature of 80 degrees, spending 3 cubic meters on this. m of gas, which is cheaper than electricity. Therefore, those who have gas in the house are more fortunate.

What kind of water heater do you prefer?

Now you know that the main answer to the question of what it takes to give up hot water is to get a heater. You know that they can be electric (storage, flow), gas, and you also know all the costs for their purchase and installation. So which one of the devices do you prefer? Of course, gas, if the house is connected to this resource.

Note! The monthly cost of hot water "on gas" is about 500 rubles. with good pressure and stable temperature.

Unfortunately, electrical devices are not capable of such “feats”. And if the house is not gasified? Then you have to think further. The overpayment will be significant here, but you can save money by choosing a heater of a cheaper model.

No one forces you to forcibly install water meters, and if you have established and realized that it is beneficial for you to pay for water in accordance with the established tariffs, then you can refuse them. To do this, write three applications (in 2 copies) according to the established model: 1) to the management office, 2) to the production association of water supply and sanitation, 3) to the management of the regional heating network.

In the applications, indicate your full address and the mandatory contract phone number. Take the second copy of each application for yourself, but make a note about the acceptance of the application with the date and seal. Copies will come in handy if your application is not answered in time or if it is accidentally lost.

And if you get a refusal to turn off the meters, you need to go to court.

In my country, it is unprofitable to pay at the established tariffs, so almost every apartment has meters for cold and hot water.

DUK will never give you a positive answer to turn off the counter.
No court will take your side with the above law.
Yes, and cases of refusal installed counter, for example, I have not heard, since the standard for energy resource consumption is always higher than the actual consumption, in this case water, according to an individual meter. And they would look at you like ... "a little, not in myself."
Even if we imagine a fantastic assumption that the DUK will satisfy your request, then you, as well as those who "have not yet installed individual counters"They will write off all the losses, that is, they will redistribute, but even you physically could not use such an amount of water.
So do not mislead people and do not leave them hope to evade the laws of the Russian Federation.

In the utility bill, charges for apartment hot water supply are usually the highest. A decent amount accumulates over the year, which can be spent with greater benefit. How to do this without depriving yourself of the usual comfort, we will tell in this article.

Benefits of not having centralized hot water supply

Inhabitants multi-storey buildings often face problems with hot water supply.

Among them:

• Water supply of insufficient temperature, because of which its consumption increases and, accordingly, the numbers in the payment increase;

• Cooling water in pipes, as a result of which you have to wait a long time for cold water to merge and hot water to flow;

• Poor water quality- it happens with an admixture of rust or with an unpleasant odor;

• Frequent planned and unplanned outages, delivering not only domestic inconvenience, but also financial losses. Indeed, in the absence of a meter, it is very difficult to achieve recalculation during the absence of hot water supply.

You can try to prove that the norms of hot water supply in apartments are violated by ordering an examination of its composition and drawing up, in the presence of public utilities, an act on the actual temperature of the water flowing from the tap.

But even if you win, it is not a fact that the problems will be solved. And this will not save you from planned shutdowns of the plumbing system for repairs.

But there is a way out, and it is very reliable: you need to install a water heater in the apartment and become your own supplier of hot water.

• It will always be pure, as its source will be drinking water from ;
• You can regulate its temperature yourself;

• Interruptions in the supply are possible only when the energy carrier or cold water is turned off;
• Impressive amounts for will disappear from the payment.

Note. On the other hand, payments for cold water and electricity (or gas, if the water heater is gas) will increase. How profitable such a solution will depend on the type and capacity of the boiler, the average water consumption and other factors. But in any case, even in the absence of savings, you get more comfort.

Design options for autonomous hot water supply

There are two ways: installing a meter on a DHW pipe with a monthly transmission of zero readings and officially turning off the apartment from hot water supply.

Counter option

Now in most houses it is required to put metering devices on all communications. If you already have counters, there will be no problems.

If they don't exist, do this:

• Install the boiler by connecting it to the cold water supply system;
• Buy a hot water meter and turn off the tap at the input.

Advice. When choosing, pay attention to performance characteristics- some devices are placed only on cold water supply.

• Install it on the DHW pipe. To do this, you need to write an application to management company for the installation of metering devices;
• Call the representatives of the Criminal Code to seal the meter and transfer the initial readings to the computer center.

This option has a great advantage: in the event of a water heater breakdown or a power outage in the apartment, it will be enough for you to open the tap on the DHW pipe and use hot water from the central system.

When using such a scheme, the following rules must be observed:

• Submit meter readings monthly, even if they have not changed as a result of not using the centralized supply;
• Once every six years (check with your supplier for a period), check the device by calling a representative of heating networks to your home.

Advice. Instead of verification, you can change the counter to a new one. It is inexpensive, and the sealing service is provided free of charge.

Disconnect option

You can completely turn off the hot water supply in the apartment by cutting off the pipe or making a gap on it.

The algorithm is the following:

• First you need to make a request to the UK or housing and communal services to disconnect from the city DHW networks;
• Then, with the help of a departmental plumber, make visible breaks in all outlets from the hot water risers and drown them out;

• Call the representative of the supplier for sealing and drawing up an act of disconnection from the network. From this moment, accruals for hot water supply cease;
• Install a water heater with piping.

The disadvantage of this option is the complete absence of hot water in the event of interruptions in the supply of electricity or a breakdown of the boiler.

Note! The fact of disconnection from the city's DHW network must be confirmed annually. Why is it necessary to call a representative of the supplier to draw up an act of disconnection and the presence of seals. Otherwise, after a year, the payment column for hot water supply according to the standards will return to the payment.

Choosing a water heater

Which boiler to choose depends on many reasons. First of all, they consider the economic one, and in this respect there is no equal to a gas water heater or column. Therefore, if the project provides for such an opportunity, and you want to save a lot, choose this type.

The only disadvantage of such a solution is that you cannot install it yourself, since the instructions require technical conditions for connection, and a certified specialist must install the column.

But the gas equipment itself is cheaper than electric, so it will pay off faster. If the house is not gasified or you are against the presence gas equipment in an apartment, buy an electric water heater.

It is of two types:

• flowing- water heats up as it passes through a heating element. It should have a good stable pressure. The advantages of such devices include small dimensions and ease of installation with your own hands. The disadvantages are high power consumption (5-27 kW), sometimes completely leveling the benefits of turning off the city network. In addition, the wiring in old houses is often not designed for such power and may not withstand the load.

• Cumulative– immediately heats a large volume of water in the tank. Allows you to regulate the temperature and maintain it at a given level. Compared to the flow one, it consumes very little electricity (1.5-3 kW), but it has impressive dimensions.

Another factor influencing the choice of a boiler is its placement in the apartment.

The easiest way to find a place for flow electric heater. It is usually installed in the kitchen at the point where the kitchen sink is connected to the water. It is also possible to embed it into the pipeline at the entrance to the apartment in order to provide hot water to all taps.

Cumulative and gas boilers cannot be placed in the bathroom. Therefore, the former are most often hung in the toilet, and the latter - in the kitchen, at the place of supply gas pipe. And from this point they make a tie-in into the existing DHW pipeline, or lay wiring to all appliances that consume hot water.

Conclusion

If you are tired of overpaying for a poor-quality service and do not want to be left without hot water even for one day, give it up. The autonomous water heater will become great solution Problems. The main thing is to arrange everything correctly.

The video in this article shows how a hot water system is installed in an apartment from a water heater. By studying it, you can most do the work yourself.

Today we will tell you how to abandon the city hot water supply system, while not only forever forgetting about weak water heating, but also doing it as economically as possible. This article will uncover some of the pitfalls of such a transition and provide a realistic payback calculation.

Why you should abandon the city hot water supply

The city's DHW system is known to many for its dismal service quality. Using it not only often costs a pretty penny, in many apartments water is supplied unheated to the established norms and its temperature practically does not rise above 40-50 ° C. To this must be added several weeks of lack of hot water during the summer planned shutdowns, when the owners are forced to heat water for domestic and sanitary needs using literally improvised methods.

There is an alternative: refuse to supply hot water to the apartment and heat it yourself using an electric or gas water heater. At the same time, interventions in draft plumbing are minimal, most devices have the simplest piping scheme and can be installed even after finishing work is completed.

What is to be done:

1. Contact the ESO or the housing and communal services with a request to disconnect from the municipal DHW system. If it is possible for the project of the house, get the specifications.
2. Install the water heater and tie it.
3. Provide for the possibility of installing seals on each branch of each of the DHW risers. The best option is plugs with loops for sealing.
4. In the presence of the inspector, draw up an act on the shutdown and the presence of a visible rupture of the pipeline.

Why is it considered saving

The benefit of switching to self-sufficient hot water seems obvious, given that the cost of one cubic meter includes the total heat loss throughout the system. For example, consider a special case for a small apartment in the Moscow region. As of July 2015, the tariffs for utilities in the region are as follows:

A family of four consumes, on average, 16 m 3 of hot water per month, that is, it pays 1,933.12 rubles for the city's hot water supply. per month. The cost of the water itself in the DHW tariff is 493.92 rubles, the remaining 1439.20 rubles. - these are the costs of heating 16 m 3 of water to 50 ° C, that is, 89 rubles each. 95 kop. for 1 m 3.

As you can see, water heating installations in the city system are not very economical, because 17.9 kW of electricity at a single rate or 14.9 m 3 of natural gas are spent on heating one cubic meter.

Payback period

But will household appliances be economical enough to pay for themselves in the foreseeable future? For the family of 4 mentioned above, about 500 liters of hot water per day are needed. This task is within the power of a pressure flowing water heater with a capacity of 6-6.5 kW or a storage heater of 120 liters with a buffer capacity and a total heating element power of up to 3 kW.

A good and reliable storage heater will cost about 10,000-20,000 rubles, and a flow heater will cost 15,000-30,000 rubles. It will be somewhat more difficult to install a flowing one, since everything that has an electric power above 3 kW must be connected with a separate cable with a core cross section of 4 mm 2 with the mandatory organization of protective grounding and disconnection, which is an additional 3500 rubles. For the boiler, you only need a differential machine worth 1400 rubles. and a regular socket on a separate protective group.

As for the plumbing piping, it is the same for both devices. Since the water heater can be inserted into almost any point of hot and cold water pipes, to connect it you will need a set of shutoff valves and 6-8 meters of pipe, which will cost another 3,000 rubles. In total, the cost of a flow-through water heater and its installation will amount to 35,500 rubles, and the storage water heater will cost 30,400 rubles.

An example of connecting a storage water heater: 1 - incoming cold water valve; 2 - safety valve; 3 - drain valve; 4 - valve for air when draining water; 5 - storage water heater; 6 - differential machine; 7 - to the shield; 8 - water to consumers

A storage water heater with a volume of 120 liters with a power of 2 kW spends 2 hours to heat water up to 50 degrees. To heat 1 m 3, he will need 1000 / 120 x 2 x 2 \u003d 33.33 kWh. That is, for self-sufficiency it is necessary that the average cost of electricity for the operation of a water heater is less than 2.70 rubles.

A flow heater with a throughput of 3 l / min will heat 180 liters of water per hour, spending 8 kWh on this. That is, its electricity consumption is about 30% higher. It can be argued that the storage water heater consumes energy not only for direct heating, but also for maintaining the temperature, however, these are short-term inclusions and such an amendment can be neglected.

In fact, only gas water heaters are economical in this regard, and they are cheaper than electric ones. With a power of 24 kW and a flow of 14 l / min, the column will warm up a cubic meter of water to 70-80 ° C in about 70 minutes, spending less than three cubic meters of gas on it.

So which water heater to choose

If it is possible to install a gas heater in the apartment project, this is exactly what you need to do. Even half a thousand rubles a month for hot water is not money, while the water is at a stable temperature, under good pressure and in full. No electric heater can do this.

If the house is not gasified, which happens more and more often in modern construction, the use of electric water heaters cannot be avoided. Yes, a small overpayment on the face, but how much more comfortable life becomes! Moreover, you can not spend money on an expensive heater, but install a cheaper one.

In both places there is a supply of both cold and hot water, pipes can be easily cut even with tees at the connection point of the kitchen sink. Do not forget that the storage water heater must be equipped with a check valve, and the flow-through water heater with a strainer.
