Species diversity of water heaters for summer cottages
The division into types and types of devices for heating water is different, based on one or another of their characteristics. The complete classification can be represented by the following table.
Before making a choice of a country water heater, it is necessary to determine several parameters regarding its further operation:
- first of all, you should decide on the place where the water heater will be located;
- then find out the maximum power level that this room can allow;
- check the accessibility to the place where you want to put the boiler;
- understand the frequency of use of the device.
One of the most common options for providing hot water is a heater, up to 200 liters, storage type, vertically installed. But, given the criteria for choosing a heater, in each case, you can choose the right option.
A very important point in the installation and use of a country water heater is safety. You should install a special security group on the device. The design of such a group includes valves connected in a single body. They are able to protect the device from such unforeseen facts as airing, hydraulic loads and overpressure. The choice of such a device will depend on the characteristics of its use.
To understand how much water heater you need to purchase, it is better to calculate water consumption for this. The parameters for this are:
After all calculations according to the specified data have been made, it is possible to determine the volume of the storage tank of the water heater.
Electric water heaters for dacha storage type
This type of device is good to use in those rooms that are provided with a good electrical network. They are characterized by the following parameters:
- low cost;
- capable of providing a large volume of water;
- it is possible to adjust the temperature to the limit of which heating will occur;
- It doesn't need a lot of electricity to work.
Not a very convenient nuance in the operation of such an apparatus is the duration of water heating.
This type of country water heaters is well suited for a situation where a sufficiently large volume of water is needed regularly, and it is not possible to install a flow-through type of device. The load that will come from the operation of the heater varies between 5 and 27 kW. In use, they have a sufficient level of reliability, and in volume they vary from 10 to 200 liters.

There are varieties of such installations and can be open and closed. The power required for the process of heating water is up to 3 kW.
Indirect heating boilers
The container of the device for heating water is made of steel and covered with a casing that provides thermal insulation properties. Water is heated thanks to the existing heat exchanger, which is represented by the shape of a coil. A coolant flows through it, due to this the water becomes hot.
A number of models are provided with a special device that allows you to heat water in the summer, it is classified as an indirect device. Thanks to him, the system is independent. The advantage of boilers is that they are able to cope with heating in a short period of time and the ability to distribute water into several streams so that several points are provided with water at once.
As for the characteristics of boilers, the main ones are:
Parameter | Characteristic |
Water heating time | A parameter that indicates how long the waiting period will be before the water becomes hot. If the volume of the device is 10 liters, then half an hour is enough to be able to use hot water. A capacity of 200 liters will need to work up to 8 hours. |
Device power | Water tanks of the same volume will be able to heat up faster if the power that the unit has is greater. Flow type devices have a power of 5-30 kW. The pressure from the tap will be the same as that of the central water supply system. An important point is the current source, because for those devices that are characterized by a low power level, an ordinary socket is suitable, and those that require a three-phase power supply from 12 kW. This applies to flow boilers. Regarding the storage type of devices, the power is up to 2.5 kW. You should not think that such power will save energy consumption, because the water will be heated to the required temperature level with the same expenditure of energy resources. A distinctive feature will be only the fact that for the latter type of boilers there is no need to build a non-standard power supply scheme. The calculation of power must be carried out for the reason that to exclude the possibility of knocking out traffic jams due to a reboot. |
Installation method | Types of installation of tanks can be floor or wall. It all depends on the volume that is needed to heat the water. Larger installations can only be installed on the floor, smaller ones can be mounted to the wall. It is possible to attach small boilers under the sink, this can additionally save space. |
Electric water heaters for giving flow type
The principle of operation of flow heaters for a summer residence or a house is such that water is heated instantly in the process.

Energy resources are also consumed during the use of water. They are characterized by the following parameters:
- are not too large;
- the ability to connect the system in such a way that it heats up at different points;
- some models can facilitate the installation task, because they do not require a tie-in to the pipeline, they can be located directly on the tap;
- there is a device in the design that includes automatic water intake for heating;
- the power of the devices varies in some models up to 12 kW, and some 12-26 kW;
- the speed at which water from the tap heats up is from 30 seconds to 2 minutes.
The disadvantages that this type of device has is the need to consume a large amount of energy resources, from 4 to 27 kW and providing a stable pressure when water is supplied to the tap.

When choosing a heater of this type, you should remember about its power consumption. The point is not that it will take a considerable amount of money to heat water regularly, but that not every dacha or country house is able to provide the required level of current.
Storage type gas heaters
The operation of this type of heating devices is similar to the principle of heating in storage-type devices powered by electricity. The only difference is that the energy source is gas instead of electricity. Such equipment is considered much more economical than the eclectic type of analogues, although the cost of such equipment is much higher. However, if we calculate the cost of energy resources during operation, then it is more profitable to purchase those that will work on gas due to a significant difference in the cost of energy resources.
Characteristics of the storage type of gas heaters:
- have installation options - can be attached to the wall or stand on the floor;
- tank volumes range from 120 liters to 1000 of those models that are installed on the floor and up to 100 liters with the possibility of attaching to the wall;
- the ability to work on natural gas and liquefied;
- the waiting time for water heating varies depending on the volume of the tank, and is up to several hours;
- they work stably, regardless of how much pressure is supplied to the tap or what the gas pressure is, which allows you to heat water even with very low pressure;
- simultaneous heating of water for supply to several taps at the same time;
- are protected more than others from the appearance of scale, even in the case of very hard water quality;
- those models that have a large volume of capacity can work on the flow type of heaters;
- there is an automatic shutdown of the gas supply in the design if necessary.
Flow type gas water heaters
A very popular type of country water heaters, because they are quite efficient and easy to use and at the same time economical. The only caveat when buying is the high price for the equipment, but it will pay off in the time that the heater will be useful and provide comfort.
A water heater for a summer house or a house of the flow type is made in the form of small devices that are built into the water supply system of the house at the place where the tap and pipe are connected. the water passing through the heat exchanger is heated. Turning the device on and off occurs at the moment of opening or closing the monograms.
The elements that make up a complete water heating system:
- automatic control equipment;
- gas-burner;
- heat exchanger.
Additional devices that the system is equipped with:
- devices for protecting the heat exchanger from an increase in temperature to an unacceptable level;
- the flow sensor provides control over the water sensor, which contains the heat exchanger;
- the presence and stability of the flame in the burner is monitored by a special safety device that prevents the leakage of the gas mixture;
- the draft sensor controls the temperature regime and, if necessary, closes the gas valve;
- controlling the intensity of the flame with a special sensor can reduce the flow of harmful substances during combustion;
- equipment with a control unit allows you to control pressure, power and temperature, which is very important when the device is operating.
Characteristics of the gas heater
Parameter | Characteristic |
Tank volume | This parameter is very important when it comes to choosing a place to install a heater and the required amount of water for use. It is also necessary to take into account the fact that, depending on the volume of the tank, the consumption of resources spent on heating is calculated, from which the amount of costs. You can also understand how much tank you need by the number of people living in the house, on the basis that one consumes a 50 liter volume. |
Coating from the inside | Such a coating, which is present on the inner walls of the boiler, is able to protect against corrosive processes. This parameter determines the duration of the device use. Most often, the choice falls on those containers that are coated with ceramics or glass porcelain from the inside, despite the fact that such a coating is cheaper and at the same time better protects against corrosion. The only disadvantage of these materials is their brittleness, it can give small cracks under the influence of high temperatures. There is another option for internal coverage. Use stainless steel or titanium coating. They have a long service life, up to 10 years. Their cost is also higher, and the downside is the fact that the taste and smell of water change, albeit insignificant. |
Power | The waiting period for water heating depends on the power. Boilers of this type basically have a power level twice as high as those that run on electricity. |
Conclusion
When choosing a heater for a summer residence, you can use the services of special companies that will carry out all the calculations and write down the benefits of acquiring one or another type of equipment. Each has a number of its features that can fully satisfy the desires of each individual.
