The most efficient water heating. Heating of water with a solar collector. Other Cheap Heating Methods
Today is New Year's Eve, so let's just rejoice. And, since it’s winter now, it would be nice to warm up a little. Therefore, today's article is unconventional water heating in winter and other lack of electricity. , so to speak.
Unconventional water heating is necessary when hot water is needed, but there are no water tanks or conventional energy sources - or you want something original. Usually you don’t want something original, so a little handicraft and humor, we hope, will be on topic.
Let's start with the theory. So, everyone knows that fire can be produced using friction. This is due to the fact that friction accelerates the movement of water molecules more and more. Therefore, if water molecules are forced to move faster in one way or another, its temperature will increase. Therefore, the first unconventional recipe for heating water:
- Let's say you're cold.
- Take a half-liter jar of water.
- Wrap with foam rubber (thermal insulation is an important point here).
- Make a small hole in the lid
- Place a whisk (hand or mixer) there.
- Insulate the lid.
- Wrap the structure in foil (you can use foil tape).
- If you have a mixer, then start whisking the water.
- If you have a hand whisk, then start whisking the water.
- After some time, the water will heat up.
- Yes, and you will warm up.
Like this one original version. We guarantee that it will be so :)
- Go to the pharmacy.
- Buy 20 jars of 90% alcohol (per liter of water).
- Wrap a two-liter jar with foam rubber and foil (insulation).
- Pour water into the jar.
- Pour alcohol into the jar.
According to the laws of chemistry, the water will heat up. If the water temperature is not sufficient, add 200 grams of concentrated sulfuric acid to the mixture. The heating will become more intense.
Both options are designed for a small volume of water. What to do if you need to heat more water? For example, here's what:
That is, candles, coasters, containers. Heating will go faster, and candle consumption will decrease if you insulate the pan (at least wrap it with foil tape).
But what to do if there are no candles, but you need even more? hot water? Here's how many, many people deal with this in an elementary way:
The only thing is that it is necessary to organize good mixing of the water, otherwise the temperature will be uneven.
And here is an improved, hotter version with organized stirring:
Second option:
Third option:
Please note: having girls without clothes raises the temperature much faster than any other option :)
Happy New Year with unconventional water heating!
On weekends, many residents of our homeland strive to quickly go to their dacha from their cities to breathe fresh air, enjoy nature and relax from the bustle of the city. And if you have a swimming pool, then the question arises: How to heat a pool in the country?
Swimming in cold water will not bring pleasure. And if children also swim with you, they can easily get sick.
Let us remind you that the comfortable water temperature in the pool for an adult is from 25 degrees Celsius, and for children - from +29 degrees.
Today we’ll look at what methods we can use to heat a pool at our dacha. Moreover, we will consider both the devices offered by manufacturers and traditional methods.
Methods for heating pool water
Electric heater
This is a fairly simple and popular way to increase the temperature in small pools, although an electric heater also has its drawbacks. The principle of operation is that water passes through a tubular electric heater (TEH) and receives heat from a dielectric heated by electricity.
It won't be difficult to install either. The photo above shows that a mini-pump is connected to one hole in the pool, then the water goes through the tube into the heating element and comes back already warm. The water heating temperature is controlled by the pressure entering the tubular electric heater - the greater the pressure, the less heating. And vice versa.
Advantages of using heating elements:
- Cheapness of the electric heater itself;
- Ease of use;
- The best option for small volumes.
Disadvantages of using heating elements:
- Not suitable for large pools (from 30 m3);
- Expensive to use - high power consumption.
Another option is to heat the water in the pool. Heat exchangers are used if you have a second source of hot water - for example, heating in the house. The purpose of the device is to exchange water from different sources warmth. Hence the name.
The operating principle is extremely simple. There is a spiral in the heat exchanger housing. There is a space around that should be filled with water from the pool. Boiling water passes through the spiral and thanks to large area interaction quickly heats the pool water.
Most often, heat exchangers are installed in the same way as electric heaters - in the circuit between the pump and the pool. In some cases, it is advisable to use two heat exchangers simultaneously.
Advantages of using a heat exchanger:
- Independence from power sources;
- Large volumes can be heated.
Disadvantages of using a heat exchanger:
- There is not always a second source of hot water available.
To heat a pool in the summer, when the main heating is turned off, using a heat exchanger is very problematic. You will have to configure and select the boiler so that it works exclusively on the heat exchanger.
If a water pump pumps out water, a heat pump pumps out heat. Everything is logical.
There are heat pumps various designs and take heat from several sources: air, soil, water. To make it clearer, we will show the principle of operation using the example of a device heat pump, which takes heat from hot air.
On this moment Such devices are not very popular due to their high price. The cheapest models start from 120 thousand rubles. We will not focus on them, but will simply list the pros and cons.
Pros of heat pumps:
- Versatility;
- Capable of heating large volumes;
- Low power consumption.
Disadvantages of heat pumps:
- High price (from 120 thousand);
- Only works in warm weather.
A very interesting device to heat the water in the pool. The water is heated from solar heat. Water is filled into the collector tubes by a pump, and when it is heated to the desired temperature, it is released back into the common tank. And again the solar collector takes another portion for heating.
In stores, collectors offer the most different sizes. You need to choose a specific model based on the volume of your pool.
Advantages of solar collectors:
- Affordable price;
- Easy to use and install;
- The volume is limited only by your budget.
Disadvantages of solar collectors:
- Effective only in sunny weather.
Budget options
Let's look at the options that can be used, as they say, at worst. This is far from the most practical ways, but they are very cheap and available to everyone.
Boiler or kettle
If you have a very small pool for children, then you can heat the water to the desired temperature in a simple, proven way. Just heat up the water in several pots and a kettle. The solution to the problem is not surprising, and it has its advantages.
- For free;
- Available.
- Only for miniscule volumes;
- A frustrating process.
Snail
The snail is a mini solar collector. They have a similar operating principle. The water is taken into the pipes, heated by the sun and returned to the pool. Its design is so simple that homemade snails are not such a rare occurrence.
Since this is a brother of the solar collector, the pros and cons are similar. But the snail is smaller in size, so it wins in price, but loses in efficiency.
Pros of using snail:
- Very affordable price;
- Does not require installation;
- Easy to use.
Disadvantages of using a snail:
- Effective only in sunny weather.
A thermal blanket can also help you heat up the water in your pool. It is also called “Special Pool Covering”. You simply stretch a special fabric over the pool, and now the heat from the sun is not reflected from the water, but is retained by the coating. Thus, in a few hours the water can warm up by 3-4 degrees.
It should be noted that in the case of a special coating, only upper layer water. To ensure that the water heats evenly, turn on the pump, which will mix the upper and lower layers.
Usually they buy a thermal blanket for a swimming pool of a special shape for a specific model. If you have a custom-made pool, then you can cut out the film yourself or order it.
Pros of using a thermal blanket:
- Affordable price of the canvas itself;
- Free operation;
- Protects against insects, leaves and other dirt.
Disadvantages of using a thermal blanket:
- Rarely is it the only way to heat water.
Pool heating with wood
If you are relaxing in the country, then getting dry firewood should not be a problem for you. Therefore, this method is more relevant in dachas than anywhere else. Therefore, you should take a closer look at such devices.
The operating principle is similar to that of a heat pump. The device takes a portion of water into its pipes. In them, it is heated by fire, and having reached the desired temperature, it returns to the pool. The cycle is then repeated again and again until the water in the pool reaches a comfortable level.
Advantages of heating a pool with wood:
- Affordable device price
- Economical operation
- Available if you have firewood
Disadvantages of heating a pool with wood:
- Not available if there is no firewood
Thematic videos
And at the end there are two thematic videos from inventive people. We are sure you will find it useful. Let's see!
If you have built a swimming pool at your dacha, then it is important to solve a number of technical problems that are aimed at maintaining this structure. One of them is heating the pool water. There are many methods for heating pool water. In this article we will look at the most common techniques.
Considering that the volume of water in the pool can be large, it will require a lot of energy to heat it. And here it is important not to overdo it by setting too powerful equipment. The temperature of the water affects not only the comfortable stay in it, but also the health of swimmers. For this reason, the temperature indicator is normalized sanitary rules, along with the content in water chemical substances and microorganisms that can harm the human body.
Based on SanPiN 2.1.2.1188-03 for water quality control in swimming pools The water temperature should be from 24 to 28°C, in wellness rooms - from 26 to 29°C, for children under 7 years old - from 30 to 32°C, for children over 7 years old - from 29 to 30°C, in hydromassage baths – from 35 to 39°C.
Based on these numbers, you should make sure that the temperature is within the specified recommendations.
As mentioned at the beginning of this article, today there are many ways to warm up the water in a pool, here are some of them:
Does anything influence the choice of technology? Yes, there are several factors that should be taken into account, namely:
- customer preferences;
- volume of water in the pool;
- features of existing communications;
- the amount of water to be heated.
To decide which method is right for you, you should familiarize yourself with each technology in more detail.
One of the most simple ways and relatively inexpensive water heating for small pools - the use of flow-through electric heaters. Their operating principle is that they heat a continuous flow of liquid with a small pressure drop. The dimensions of the equipment are quite compact, so there is no need for additional equipment Utility room. A small booth will be enough.
As for the electric heater itself, its body is made of high-quality of stainless steel, titanium or plastic. Heating elements are able to withstand high temperature and this is achieved thanks to the stainless steel alloy.
When choosing this heater, keep in mind that its power must be equal to the volume of water. For example, if you have a shallow pool that is located in a heated room, then most likely a power of 3 kW will be sufficient.
The maximum that instantaneous electric heaters can produce is 18 kW, which is not a lot. Therefore, for a large outdoor pool, you will have to look for an alternative, and in particular if the pool has more than 36 cubic meters of water. Plus, the wiring in the house may not be able to handle such a powerful heater.
So, if we talk about the advantages of this unit, it is quite fast warming up, the ability to control the water temperature, set the automatic control mode, as well as the presence of a sensor that, in the absence of circulation, turns off the heating system. Well, we have already discussed some of the disadvantages, namely low power, high energy consumption and restrictions for houses with weak wiring.
This equipment, unlike the previous one, has more advantages, in particular in terms of energy consumption. Water is heated by connecting a heat exchanger to the heating system of a residential building. In appearance, it resembles a flask with a coil inside. Water moves along it. During circulation, the water is heated to the required temperature. As for the flow of water into this flask, it is regulated by a pump and valve. This valve is controlled by a thermostat. The coil is washed with chilled water from the pool. As you can see, everything is quite simple.
If you install such a water heating system, then the desired temperature is set on the thermostat and the automation will do the rest.
Let's talk about power. It can range from 13 to 200 kW. Accordingly, the choice of power depends, in this case, on the volume of water in the pool. The more it is, the more powerful the equipment is needed. This also affects the duration of water heating.
The principle of the heating system is as follows:
- At the very beginning, the water is heated by a heat exchanger for two days at maximum power.
- This is important, otherwise instrumental collapse may occur, which implies a structural change in the heater body and individual elements.
- After this, the equipment will only need to maintain the water temperature.
The heat exchanger itself is installed between the disinfection system and pumping station. This will completely avoid equipment breakdowns due to the presence of chlorine in the water. If the water has excessive chlorine levels, it is recommended to install a titanium heat exchanger.
As can be seen from this description, the heat exchanger is much more economical, easier to operate, and also has high power. The only negative is the long wait for the water to heat up to the desired temperature.
If you are looking for the most inexhaustible source of energy, then it is, of course, the sun. The main thing is to tame its energy so that you can heat the water in the pool. One of the easiest ways to do this is to install solar panels. Although under open air, the water itself can warm up from the sun’s rays; a completely different picture is in the case of an indoor space. Just the same, solar and solar systems will direct the energy of the sun in the direction you need.
This system consists of separate modules consisting of screens, tubes or cones. Each individual module can heat up to 30 cubic meters of water. If there is more water, then more such modules are needed.
The operating principle of solar panels is described below:
- Collector accepts Sun rays. The collector itself is usually black.
- The collector completely absorbs the rays.
- The collector located inside heats up to 140°C.
- After this it starts circulation pump. It is installed in a storage tank.
- In just a short time, the water in it quickly becomes hot.
- As a result, it can be used for a swimming pool.
More expensive models of manifolds include sensors and three-way automatic valves. Due to this, water is sent to the heat exchanger automatically. Thus, continuous circulation of water is organized.
If you select positive sides this technology means very fast heating of water, simple system management. But if the weather is cloudy, then the efficiency of such a system will decrease significantly.
If you are interested in heating speed and power, then heat pumps are the new and most popular way to heat water. The only thing that scares many buyers is the high price. The principle of operation is as follows (the action resembles the operation of a coolant that uses condensates, etc.):
- The primary source of heat can be industrial or domestic wastewater that has been treated.
- The external pipeline is located underground.
- It is pumped through working fluid using a circulation pump.
- Due to the temperature of the soil, at the outlet this liquid increases in temperature by several degrees.
- Next, the mixture is sent to the heat exchanger.
- In it, the liquid gives up its heat to the refrigerant, which quickly boils. Even a low temperature is enough for it.
- As a result of boiling, steam is formed, which enters the compressor and is compressed to 25 atm.
- During this process the temperature rises to 55°C.
The energy resulting from such actions is sent to the pool to heat the water. The work of the entire system is carried out in a closed circle, according to the principle of circulation. As a result, the power of the heat pump can be used for other household needs. For example, you can provide heat to a house up to 300 m2.
An important advantage is expressed in high power and the speed of water heating. Free energy sources are also used: earth heat, exhaust gases, Wastewater etc.
We looked at options for heating a pool that are quite expensive. Now we bring to your attention heating options from do-it-yourselfers. The main advantage of these techniques is minimum costs. Consider one of the many options homemade unit for heating the water in the pool.
Firewood has been and remains the most affordable source of fuel. It's strange, but industrial units using this fuel no. Therefore, a homemade water heating system was invented. The essence of this idea is that a metal coil is installed inside the firebox. Water is supplied to the inlet using a pump. Through the second hose, the heated water in the coil enters the pool.
The main thing in this method is to select the speed of water movement. Otherwise, the water may either boil or not warm up enough.
Another option is to install a coil, inside which a fire is built. A risky method, but it has its place. You can easily use it on a hike. The only thing that needs to be considered is the removal of hot water. To do this, you can use a heat-resistant hose or metal-plastic pipe. In this case, heating will be realized without electricity.
It's one thing to heat water, but without good heat retention, you will have huge energy costs. It is a known fact that a large amount of heat is lost at night. To reduce losses, you can build a canopy over the pool. In this case, the canopy can be:
- Folding.
- Sliding.
- Stationary, etc.
If it is not possible to install a canopy, then you can use a blanket or film that floats on the surface of the water. The film must be straightened at night and removed in the morning, then the water will have enough comfortable temperature, and the cost of heating it will be reduced.
Instead of film, you can use awnings that cover the entire surface of the pool. But the disadvantage of this option is that it will be inconvenient to put even a small awning over the pool alone. However, they are quite effective.
For example, if you have a rectangular pool, then straightening the awning is as easy as shelling pears. On one side, at a distance of 1.5 m, attach light planks. Holding on to them will make it easier for you, even alone, to straighten the awning.
So, we discussed how you can quickly heat the water in the pool. Choose the technology that is available to you. We and our readers will be interested to know how you heat your pool at the dacha, so leave comments at the end of this article.
10 ways to wash yourself without hot water
Summer in Russia is not summer without planned shutdowns of hot water. The housing office says that washing with cold water three weeks a year is simply necessary. You are itching, and at this time they are carrying out preventive measures in the boiler room.
But there’s no need to itch – Pics will tell you ten ways to live this time without conflicts with hygiene.The most obvious way
The simplest and most obvious way to wash your body in the absence of hot water is to heat it in a large saucepan or bucket. There seems to be nothing to explain here. You heat the water harder, and then dilute it in another container to make more. You sit in the bathroom and carefully water yourself with a large mug or ladle. Lathered up, washed off. Lathered up, washed off. The method is quite effective, but for some reason it evokes terrible melancholy and decay.
Technical progress
Until your electricity is turned off, you can heat water using electric kettle. It's much faster than waiting for a large pot to boil on the stove. Of course, one kettle is not enough. You will have to put it several times. While you wash your hair with one portion, the second is ready for your body. Unless you have a Bruce Willis haircut, your head will take as much water, or even more, than the rest of your body.For the desperate
Do you remember what a boiler is? Yes, this is the thing that sometimes gives an electric shock. But, if it is working properly, then of course there is no danger. The main thing is to triple check. There are large, powerful boilers that our ancestors used to boil water in buckets. You lower such a device into a filled bath and wait until the water warms up to the desired temperature. After that, you climb into it and rinse yourself. We recommend pouring water for rinsing into a saucepan or bucket in advance. Otherwise, such washing will not be of much use.
Lifehack for those who have long hair To save water when washing long hair, wash the hair at the roots and, in fact, the head itself with warm water, and wash the rest of the hair under the tap. The hair doesn't care about the cold, it's just the skull that's freezing.
Like an astronaut
Have you ever wondered how astronauts wash themselves in orbit? The answer is simple, they don't wash. They just haven’t figured out how to do it in zero gravity yet. They are wiped with special wet wipes. In one pack - for soaping, in the second - for wiping. You can do the same. Packs wet wipes quite enough for the whole body. Or wet a towel with warm water (take it in a kettle) and dry yourself as much as you like.Like an athlete
Have you been to a fitness club or swimming pool lately? Summer is the time to correct your figure. Moreover, in such establishments there is always a shower. Hooray! You can put yourself in order in every sense of the word. Continuing logical series, you can go to visit your parents or friends. Don’t forget to briefly check with them about the hot water at the tap. If people are good, they will not refuse a bath.
Emergency Rescue
The water was turned off unexpectedly as always. This means it’s time to take emergency measures. Go to the hardware store and buy flow heater. This is such a thing that is put on a faucet and connected to the network. You turn on the water, then the heater and enjoy a thin stream of warm water. You won’t be able to wash yourself with pleasure under such a stream, but, nevertheless, in the absence of fish, even cancer is a fish. If you know that in the summer you cannot avoid turning off the water, then install a large flow-through heater in advance. This is a 40-80 liter tank. It is usually hung in the bathroom or carefully embedded in a shaft with pipes in the toilet. Great item ! With it you can easily wash yourself as usual, without looking at the time and without fear that you will have to rinse under water..For the desperate
There is such a thing called “dry shampoo”. It is a spray that needs to be sprayed onto dirty hair. Then you massage your head and smear it all over your hair. Then carefully comb your hair with a fine comb. In theory, they should look better now. “Dry shampoo” removes oil from the hair and loose flakes from the scalp. In fact, the cleaner your head is before you start “washing,” the better the result will be, because this product works so-so.
For the inventive
You have houses washing machine? So, with its help you can not only wash your clothes, but also successfully heat water. You choose the fastest mode with boiling, but do not add laundry and powder. You direct the drain into a previously plugged bathtub. The machine will take water, heat it, simulate washing and pour it into the bathtub. This is what people's ingenuity means. We have already talked about what to do with the water in the bath. And don't worry about its quality. It will be as clean as the tap.The escape
If you are disgusted by all these schemes for obtaining hot water in your apartment, then you can simply go on vacation during the shutdown. Find out from the housing office in advance when they are planning Operation Dirty Harry and get yourself tickets for that time. Go to a place where all the amenities and relaxation from the everyday hustle and bustle will await you. You will rest, and at the same time wash yourself.Want to receive one interesting unread article per day?
