Access to hot water is one of the most important factors affecting the high degree of user satisfaction with this apartment or house. The power of the selected heater depends on several parameters - first of all, on the number of people living in this room and the degree of water consumption. As a rule, the estimated need for hot water is about 15-30 liters of water per capita. With a large family and a high standard of living, this indicator should be increased accordingly, how to choose the best boiler for you, the store's experienced consultants know https://www.foxtrot.com.ua/ru/shop/dnepr/bojlery.html
Availability of hot water
It is one of the most important aspects affecting the quality of household use. Its shortcomings, which arose as a result of choosing a device that is too small, will be the result of a constant, systematically increasing bill and much faster wear of the tank.
How much water do we use?
Taking into account various conversion factors and systematic studies, the average user uses 50 liters of water. The average temperature is about 40 degrees. Thus, a tank with a capacity of about 150 liters should be enough for a family of three people.
However, these are very simplified calculations that do not show the full scale of the necessary need for hot water. The type of activity for which we use hot water, the comfort of life, the planned economy or, on the contrary, their absence, are also important.
According to indications
A significant increase in the generally accepted amount of water is produced when bathing, the remaining amount goes to the shower and washing hands and dishes. Thus, if residents prefer long baths, they should equip themselves with much larger tanks.
Another solution would be an installation with a boiler that quickly heats hot water. If, for example, you heat the water to 60 degrees Celsius, then when mixed with cold water, it will not give us 150 liters, but much more. In order to correctly choose the capacity of the tank, it will also be useful to analyze how many points water will be drawn from. A good example here would be, for example, two bathrooms located in one house. The water flowing into the faucet in both bathrooms must have the same pressure. Let's assume that both bathrooms are equipped with bathtubs, then: To fill a small bathtub requires 100 liters, a large one - even 250 liters. In turn, we can use from 70 to 250 liters for a 10-minute shower. Of course, this is also affected by the installed boiler system. We also have to check the water flow. In a standard shower, it is 7-8 l/min, and in a more complex panel, it is 15-25 l/min. Such values should always be correctly calculated and added up, draw conclusions, and only then choose the right heater.
How do we heat water?
We can choose a coil, i.e. a pipe in the form of a spiral attached to the bottom of the tank. It is through it that hot water flows from the boiler, which transfers heat to the technical water. Or layer-by-layer storage tanks equipped with an additional solar coil and a circulation pump with a controller. The second option assumes a very high water output.
