Choosing an electric water heater to give

The issue of hot water supply is one of the very first on the list of beautification of a summer house or a country house. It is no secret that after taking care of the garden, you need to take a shower or at least wash your hands, and it is quite problematic to do this without hot water.

It is because someone builds baths, someone sets a summer shower, someone heats water on the stove. But if there is a water supply system or a well on the land plot, then the best option would be to buy a water heater.

In any weather at the summer cottage work always boils, after which there is a natural desire to wash. Of course, you can overheat the bathhouse, but, firstly, not everyone has it, and secondly, to do it every day is very uneconomical.

You can, of course, install a container, the water in which collects the sun's heat, but in rainy or overcast weather this will not give any result. In this case, it is better to buy a water heater.

Immediately, attention should be focused on the fact that the “heating” for the dacha is significantly different from the water heater, which is mounted in city apartments. The design, which is installed in a country house, must meet several basic requirements:

• Low power consumption - the owners of the dacha plots are already forced to pay for land, services of the dacha cooperative and much more, so the increase in electricity costs can be a very unpleasant surprise for many.
• Optimum tank volume - for a small country house it makes sense to purchase an installation with a small tank, but in country houses with long stays, as well as in families with two or more children, it is worth thinking about a more dimensional model.
• Correlation of power wiring to power heater - on this issue, it makes sense to consult with an electrician who will calculate whether the parameters of the column correspond to the possibilities of electrical wiring in the house.
• Practicality and ease of use - however, this factor applies to any electric heaters, regardless of whether they are installed in urban homes or country farms.

Acquisition of a heating tank for the garden is not a simple matter. Modern industry offers a wide selection of various models: wood heater, gas and electric. They differ in their performance parameters and structural features.

That is why, before making a purchase decision, it is necessary to understand what kind of water heater models are and how they differ.

First of all, the devices differ with respect to the installation site:

• Wall mounted. Such models are considered more optimal in terms of convenience and ergonomics. As a rule, they have small dimensions, so they can be used in small rooms. The capacity of such tanks is also small, they are preferable for families with low consumption of warm water per day.
• Outdoor. The dimensions of such structures are much larger, therefore they are suitable for larger premises, respectively, and the volume of the storage tank in them is also larger - from 80 to 200 liters.Such installations are optimal for families with children, as well as in cases where the owners of the dacha live on it for a long time, and do not come a couple of times a week for a few hours.

According to the method of water intake can be bulk. This option is suitable for cottages that are not connected to the central water supply. As is known, there are many such farms in our country. This installation is equipped with a reservoir that is filled manually with a scoop, bucket or watering can. Designs are often completed with a sink or a small shower.

Such water heaters are very popular. The mechanism of their action is simple: the boiler is filled with water, after some time it is heated to the set temperature, and then fed through a special faucet, which is mounted at the very bottom of the tank.

Bulk water heaters have a lot of advantages:

• they have a particularly robust container made of stainless metal, which is quite practical and durable;
• simple technical device apparatus, which does not require special skills for successful installation and further operation;
• a wide range of models with different heating elements of different capacities;
• the presence of a thermostat, which eliminates any evaporation of water, and therefore significantly prolongs its service life.

Instantaneous water heater is used when the cottage or country house is connected to the water supply. In this design, water is heated as the fluid flows through the heat exchanger of the heater. For efficient operation, the average water pressure is sufficient, so it is suitable for dachas, where the pressure problem is one of the most frequent.

Accumulative water heater is more suitable for country houses with permanent residence, because it has a large storage tank, the water in which is heated with the help of built-in heating elements. The basic advantage of the device is the possibility of creating hot water, but this does not exhaust the list of advantages:

• the heater has the ability to keep hot water in the tank for a long time;
• in the event of a power outage, it may supply previously heated water;
• allows you to program work at night, to heat the water for morning hygiene procedures - this reduces the cost of electricity, the rate for which at night is much lower than during the daytime hours.

On the pressure of water devices are pressure water heaters and pressureless.

Pressure devices crash into water pipes and therefore function under conditions of constantly maintained water pressure. Water heaters are able to provide water to several areas of water at once, so one person may, for example, take a shower, and another at the same time wash dishes in the kitchen.

The operation of the heaters is performed automatically and is activated by the movement of the crane. Such models may have different capacities, so choosing the best option for your home is not a problem.

Non-pressure apparatus requires the installation of water fittings, which must be installed on each tap. The model is designed for only one point of consumption. Power device does not exceed 8 kW.

Water is supplied by hand or using a pump. Models are often equipped with a kitchen or shower nozzle.

Free-flow options are good for small houses, but in the cottages it is better to give preference to other options.

Depending on the water supply option there is several heater connection methods:

• Connection to water tank - it is very important to observe the distance between these two installations, which should not be less than 2 meters. The second thing that needs special attention is pressure, which must be less than 6 bar. If it is higher, then it is necessary to supplement the design with a special gearbox, which will reduce this pressure. The gearbox is mounted directly in front of the water heater. If we neglect its installation, it will inevitably lead to the failure of the equipment.
• Water connection - This option is used if the cottage has access to central water supply. Installing such a heater is not difficult,however, minimal knowledge of plumbing devices will still be needed. Before connecting the tank to the water supply, hang it on the wall. To do this, it is necessary to purchase very strong and overall mounts, which are rarely sold in a set with a tank, so you should take extra care to purchase them.

Even before connecting the water heater, it is necessary to determine its location, at the same time it is necessary to provide several principal points:

• The wall must be durable and stable, since even the smallest heater has a rather large weight, so thin walls and partitions can crack or collapse under the weight of the installation.
• The heater must fit its dimensions in the wall so as not to dock with other structural elements.

The choice of heaters presented in stores is very wide. Which is better for giving? The answer to this question is not so simple.

First of all, it is necessary to clarify whether it is possible to connect the device to the water supply system - this largely determines the choice of model.Equally important are the dimensions and furnishings of the room in which the boiler will be installed. If the room is small, it is worth buying wall options, and if the boiler room can be given a separate unit, you should give preference to floor structures.

If gardeners will arrive at their site on weekends, then the capacity may be small, and if you plan a long stay, you should prefer cumulative models with a spacious tank.

The number of family members and their age is another important point. If a family of 1-2 people is satisfied with a low-power boiler with a small tank, then families with 3 or more members, especially if there are small children among them, will at least double the flow of warm water, because the amazing ability of children to get dirty is known everybody.

If you are looking for compact models of 15 or 20 liters, mainly for domestic use, then it is worthwhile to dwell on flow-through options, especially since their cost is quite democratic, they are easy to use, and anyone can understand the features of their use.

Be sure to pay attention to the power supply requirements. It should be an AC mains with a voltage of 220 watts. The maximum allowable deviation should not exceed 20V, otherwise the installation simply will not work.

Each manufacturer additionally indicates the frequency of the equipment, since the overall stability of the device depends on it. This indicator for a device with a power of 15 kW should correspond approximately to 40 Hz.

It is desirable that the maximum temperature be set at 50-60 degrees.

Very often on the heater can be found marking IP25. It means that the design has a certain degree of protection against leakage and that it has a built-in system that quickly monitors all faults in the equipment. This is very important, since such a model is turned off as soon as interruptions occur in the functioning of the system. The same applies to the water intake - if the tank for some reason cannot be filled (for example, when the water supply is turned off), the device should be turned off.

The sequence of actions when installing a water heating structure is as follows:

• To begin, an assessment of the installation site is made. Equipment with a volume of not more than 200 liters can be hung on the walls. Larger tanks should be installed on the floor, otherwise an unavoidable attachment is inevitable.
• Next, the model must be fixed. Anchor bolt should be used to fix wall models. It must be purchased separately, as the basic equipment does not provide for its availability. The more brackets you use, the more reliable and stable the design will be. It is optimal if the model per 100 liters is equipped with 4 brackets.
• If the device is installed in a hard-to-reach place, then it is necessary to think over in advance all the nuances of its maintenance. If there is a need for repair, it will be difficult if access to the tank is blocked.

So, there is a need to use storage water heater. You need to enable it, and to do this, follow these steps:

• Shut off the tap with hot water, which is installed on the riser. If this is not done, the water treated by the heater can flow into the general water supply system.
• Open the valves and water heater valves.
• Then it is necessary to open the tap supplying water from the tank.
• After the main manipulations, you should connect the device to the AC network.

It is believed that electric water heaters often fail, are not of the highest quality. Reviews say that these devices are quite unreliable technique. This opinion is devoid of any reason. Water heaters fail no more than any other equipment, but the errors in the operation of the device increase the likelihood of breakdowns. There are several rules of operation of the device that will allow him to work faithfully for many years:

• The device never needs to be put on the highest temperature of heating.If you set the maximum mode, the design can quickly burn out, the life in this case often does not exceed 6 months. In addition, if the water temperature is close to the boiling point, then the user can get burned in case of leakage of pipes or hoses. You should not expose yourself and your loved ones to such a risk.
• If the model has two heating elements separated from each other, then it is optimal if it works only on one heating element. In this case, if one of the heating elements fails, the second continues to function and heat the water.

• Before buying the device, pay attention to the instructions for use, and, in particular, the maintenance of the device and the need to replace the magnesium anode. Every six months, it is necessary to completely drain the water from the tank and remove the heater with the anode for external inspection. If it is covered with a lime scale and the anode itself is almost dissolved, it should be cleaned and the old anode should be replaced with a new one.
• Do not forget to regularly replace the check valve in the water heater in the event of a breakdown. The signal of such a malfunction can be a characteristic "moaning gurgle" at the time of turning off cold water.This indicates that the valve does not cope with the tasks entrusted to it, namely it does not hold water, therefore the fluid flows back and the heating element starts to idle, which inevitably leads to burnout.

That still needs to be considered when choosing an electric water heater, see below.
