Cottage for many people has become a second home. Accordingly, the desire of summer residents to have comfortable living conditions is understandable. Urban comfort in the country with modern technology is not so difficult to achieve. One of the most important components of civilized conditions is the presence of hot water. The water heater for giving bulk with the heater – the simplest, inexpensive and unpretentious solution to communications.
Varieties of water heaters
By type of energy water heaters are:
- gas;
- solid fuel;
- sunny;
- electric.
Gas water heaters have a high thermal capacity (up to 30 kW), but their use is possible only if there is a gas pipeline in the holiday village or with a special setting for bottled gas. The use of bottled gas is troublesome from the point of view of refilling cylinders, requires increased caution during operation. Installation of heaters of this type requires coordination with the gas service, and their operation requires annual maintenance (maintenance).
Solid fuel – very autonomous water heaters, can work in the absence of gas and electricity. However, they are difficult to install indoors, because the construction of the chimney requires special knowledge and skills. The use of solid fuel always takes a lot of time, due to the laying, ignition, maintenance of combustion, removal of combustion products.
Sunny – the most eco-friendly, absolutely autonomous, the simplest water heaters when installed. Very effective for giving in the summer. In late spring or early autumn, they can be involved only on particularly warm sunny days.
Electric – the most massive. Combine the advantages of different types and successfully solve for many problems. Among the advantages of such water heaters point out the difficulty of supplying electricity, sufficient environmental friendliness, ease of installation, installation and operation.
Helpful advice! Installing an electric heater in a sunny place (a summer shower or a wash basin) will significantly save energy. Power in turn is a backup source of energy on cloudy days.
Electric water heaters are divided into:
- flow;
- accumulative;
- bulk.
Flow through – very productive and comfortable for the shower. Manufacturers offer a wide range of instantaneous water heaters to give. Characteristics, prices and design solutions are the most diverse. However, such heaters require plumbing of sufficient pressure (at least 2 l / min). Enough complex in the device and repair. Due to the high power (not less than 8 kW) they are designed for a separate power supply of 380V.
When supplying 220V, such power requires separate coordination with a local electricity supplier. To achieve such heat output, gas water heaters are more efficient than electric ones.
Accumulative water heater allows you to do much less power (up to 2 kW) due to the use of time when hot water is not used. Also the accumulative type of heaters is insensitive to the pressure of the water supply.
Bulk water heater on the device is similar to the cumulative. The principal difference is in the water inlet through the top cover, that is, such a heater can be used for summer house without running water. It is convenient to use such a heater if a washstand or a washbasin is installed at the cottage.
Helpful advice! If you want to install a flow or storage water heater to give, and you have a choice between the gas and electric options, you should correlate the cost of gas and the cost of electricity. According to the tables of specific heat of combustion of fuel, 1 m? Natural gas is equivalent to 8-10 kWh of electricity.
The bulk water heater is a tank of various capacities: from 10 to 250 liters. As a rule, the tank has double walls to create a thermos effect. External walls are made of steel, internal – steel or plastic. Inside the tank is a heater. A number of manufacturers use the design when the heating element is below the drain valve. This is not always convenient if you need to remove all the water from the tank, for example, before winter.
Some models use a water level sensor to protect against “dry” inclusion. Also a mandatory element of the water heater to provide a bulk with a heater is a thermostat that allows you to maintain the temperature in the tank from 20 to 80 ° C. The heating temperature is determined by an external temperature controller.
Installing any storage water heater to give is simple and does not require calling a plumber. Small storage tank can be hung on the wall, large models of water heaters should be mounted on the floor. Also be sure to ground. Experienced gardeners do not recommend manually filling the water heater with the heating element turned on.
Important! To protect against voltage surges, electrical devices at the cottage must be connected through a stabilizer. A limiter can be used for the water heater, which disconnects the circuit in case of low or high voltage.
Among the manufacturers of heaters for giving the most famous brands are Ariston, Atlantic, ATMOR, Bosch. Also, you can choose a cumulative or bulk water heater among domestic manufacturers. Among domestic manufacturers, Alvin has a strong position in the market.
For country houses without plumbing, EVBO water heaters (Alvin’s own original design) is a simple and economical solution. This series is equipped with plastic tanks, placed in a metal case. There is an air gap between metal and plastic, creating the principle of a thermos. Also, the system of built-in thermostats allows you to get the most comfortable water temperature.
A typical example of a water heater in this series, the most suitable under the sink, – EVBO-20. With an average price of 2100-2200 rubles, it has the following parameters:
- capacity – 20 l;
- power – 1.25 kW;
- heating time to 45 ° C – 45 minutes;
- height – 410 mm;
- width – 360 mm;
- depth – 320 mm.
Water heaters of the EBO series of larger capacity are suitable for a shower, but they cost a little more. For example, a 60-liter heater will cost up to 5,000 rubles.
It should be mentioned another domestic manufacturer – SUCCESS. The peculiarity of its development is that the storage tank is made of stainless steel, the seams of which are glued together with a sealant. This design eliminates leakage. The thermostat allows you to set the heating in the range of 15-70 degrees. The cost of devices in this series is not high and depends on the size of the tank: 1500 – 2500 rubles.
Helpful advice! If you have not used the water heater for more than a week, before turning it on, make sure that there is water in the tank, even if the heating element is below the level of the tap. This is due to the property of water evaporation, especially in the hot season.
The simplest wash basin for the dacha is the so-called “moidodyr”. It involves the installation of a water heater at the sink. Waste water flows into a special container under the washbasin bowl. A wash basin of this type does not require heating a large amount of water. The recommended tank capacity is a maximum of 20 liters. With a 20-liter tank, the sink remains very compact, at the same time it contains enough water to wash the hands of all family members. Conveniently, the washbasin can be “refueled” with warm water, for example, taken from the shower.
The variety of choices on the market is great. Attentive and thoughtful attitude to the selection of the water heater will give you at the cottage joyful work and comfortable rest.
