Hot water supply to a private house
Hot water supply has become quite common. To date, there are many devices for heating water. They can work from electricity or gas, so in any homeownership it is possible to equip this type of water supply.
According to the principle of operation, there are two systems of hot water supply:
- flowing;
- with a storage boiler.
Their difference is in the accumulation of hot water. In the first case, it does not occur and the liquid heats up if necessary. The second type includes a tank for storing hot water. On the devices for the water supply system will be described further.
Hot water supply scheme for a private house
Before talking about appliances for heating water, you need to determine the water supply plan.
They can be divided into several types:
- standard;
- with forced circulation;
- with the use of a collector.
When the third option is implemented, the water is divided into hot and cold water. A heater is installed in the system of pipes for hot water supply. It can be flowing or cumulative. Piping can be serial or parallel. When installing this scheme, less material is needed, which means that the price will be lower. The drawback of this system can be considered the difference in pressure in the cranes, in the closely located head pressure will be greater than in those that are located at distant sites. And to reach the water to the distant taps will be no longer hot due to cooling down.
At the second kind of a pipe are brought to each water intake. This scheme is quite popular.
Forced circulation has several advantages:
- the same head in the pipes;
- the water does not cool down;
- the absence of pipe joints in the interstitial floors.
Without shortcomings, it was not unsuccessful, here they are related to the price of the project. To install such a system requires more pipes and materials, and hence the cost will be more expensive.
For a private house, the most optimal is a closed circuit. A pump is installed in the system, which maintains a constant circulation of the liquid. This ensures a stable temperature. And the length of the pipe section in which circulation is not necessary does not exceed a meter. In such places a towel warmer is often mounted. In this scheme, the installation of a check valve is mandatory.
The shortcomings of a closed system include:
- more material is required;
- high price;
- high heat costs.
In any case, heating elements (gas columns, heaters, boilers, etc.) are needed in the hot water supply system.
equipment for hot water supply
The simplest device for heating water is a running water heater. They can be electrical and gas. The first type is convenient in the absence of a gas main. They are compact and have an attractive design. Gas are a well-known column that is popular among the population. He will quickly heat the water and keep the set temperature. Due to the variety of decorations the device can be inscribed in the kitchen of any design. When choosing a flow heater you need to know the following: a shower or bath consumes 9 liters of hot water per minute; washing 4.2 liters per minute.
Adding the indicators of the prospective flow points, you can calculate the required power of the device. Also pay attention to the temperature difference. The device should provide water heating up to 55 degrees.
Gas flow heaters are convenient. The water pressure and temperature can be adjusted as desired by the user. They are beautiful externally. But without a centralized gas supply system, it makes no sense to install them, because The water is heated by a gas burner.
You can also use boilers. They can work from electricity or gas. In most cases, they are equipped with a container in which water accumulates and heats up. They have different volumes, the best choice for families is more than 200 liters. They can be mounted both in the heating system and installed independently.
Perhaps the simplest option is the installation of a double-circuit boiler, which is used for heating and heating water. They can be wall-mounted or floor-standing, which is convenient for installation. The only drawback is the loss of heating power while using hot water, because The burner can not heat two circuits at the same time. This does not mean that the house will immediately become cooler, you just need to know about such a constructive feature. Such a device will save money on the purchase of several devices, as well as pipes.
pipes for hot water supply
Many water supply pipes are on the market. The choice of the required material is not simple and mainly should be guided by the reliability of the material and the price segment. Another major aspect is the installation of pipes, it should not cause significant difficulties.
Mainly it is necessary to pay attention to the material of manufacture, namely:
- steel;
- copper;
- plastic;
- metal-plastic.
Steel pipes can withstand significant changes in temperature and pressure. They are made mainly of black or galvanized steel, which has a favorable effect on corrosion resistance. They have a long service life of 50 years. When installing them you need certain skills and tools, so an inexperienced master to make a water pipe from them will be difficult. The disadvantages include the formation of condensate on the outer surface of the pipes and the formation of plaque inside, which prevents the normal passage of liquid.
Copper pipes have a long service life of 70 years. They have an attractive appearance that can become an independent element of decor. The main disadvantage is the high cost and finding such material is also not easy.
Metal-Plastic Pipes practical and light in weight. They are easy to assemble. This pipe consists of a frame covered with the outer and inner sides of the plastic. The service life is about 35 years. They also withstand temperatures of up to 75 degrees Celsius. The main advantages are affordable price, easy installation and reliability. Of the disadvantages, it should be noted low frost resistance, so it is best to make from them intra-house wiring.
Plastic pipes durable, versatile and very affordable. They are very popular among other materials. Also worth noting is a neat appearance.
For their manufacture can be used:
- polypropylene;
- polyvinyl chloride;
- polyethylene.
Of these, you can quickly make a water distribution system. All the work can be done independently, this will require only a wiring diagram, pipes and a welding machine.
apparatus for welding PVC pipes
If you need to install water from a plastic pipe yourself, you will need a welding device. Such a welding apparatus consists of a heating plate, a comfortable handle and a strong housing. It's easy to use. Manual and mechanical models are on sale. Hand-held devices are able to work with pipes with a diameter of not more than 50 mm. It has small dimensions and is easy to use. Therefore, it is suitable even for people with a lack of experience in such works. The only drawback is the restriction on the diameter of the pipes, but for the domestic water supply is quite suitable.
Mechanical machines are difficult to use, so they will suit experienced craftsmen. With their help, it is possible to join pipes with a diameter of 40 mm.
When choosing a welding machine, it is necessary to pay attention to:
- The producer's country is better to give preference to European brands (for example, the Czech Republic), the instruments of the Chinese or Turkish production of the master do not favor, there is a very great opportunity to run into a marriage.
- Capacity for the installation of pipes with a diameter of 16-75 mm, it can be 0.85 kW, and when installing pipes 90-125 mm in diameter, the apparatus should have a power of 1.5 kW.
- The nozzles are supplied with the soldering iron and have the dimensions equal to the diameter of the pipes with which this model can work. Experienced masters recommend buying kits with nozzles with a diameter of 16, 32, 50 and 110 mm.
Also an important aspect is the price of the device. So the cost of manual models varies from 800 to 3000 rubles. Mechanical costs from 16 to 180 thousand rubles. Therefore, before buying, clearly appreciate why you need a welding machine and do not overpay.
Installation of hot water supply by one's own hands
Your house has already been supplied with water. Piping is also available for all faucets and plumbing fixtures. Now it remains to decide how to heat it. The very first way is to install a two-circuit gas boiler. One circuit of which will heat water for domestic purposes, and another for heating. From the central water supply to the boiler a pipe with cold water is fed, and from it there is already a pipe for hot water supply. It is also possible to install a conventional one-circuit heating boiler. Also have to install a boiler for hot water in household needs. Fortunately, now many manufacturers produce kits from a boiler and a boiler. Alternatively, you can do with an electric water heater with a storage tank. As the flow of water, it is filled and the liquid is heated. In large houses, flow heaters can be installed, and it is best to do this for each consumer. In other words, each tap should have an individual water heater. Which way is right for you to decide, it is worth saying that the first option is more suitable for private homes.
Helpful Tips
When you are using hot water, you can advise the following:
- during the construction phase, you can immediately install a boiler for 100 or more liters, this will provide comfort to the residents and the need for further rework of the system;
- if the house is used for a short time (as a summer residence) it makes sense to install a flow heater, it is compact and convenient to use;
- if you have a large family you can install an additional tank of 30 liters with heating, it will compensate for heat loss and water consumption;
- when purchasing a gas boiler, give preference to the already ready boiler boiler sets, their parameters are ideally suited to each other;
- if the water in your area of residence contains more than 140 mg of impurities per liter of flowing water heaters is better not to use, quickly fail due to the fallen salt on the walls of the pipes;
- when heating the house with a solid fuel boiler, you can use the heat accumulating tank, so you organize a secondary hot water circuit and reduce the energy consumption.
