Self-installation of the heater

Summer planned shutdown of hot water bringsin our lives a lot of inconvenience, and first of all they are connected with the inability to fully take a shower, wash dishes with hot water. According to statistics, every third inhabitant of the urban heat water for bathing and other needs in buckets and a large pot, while the installation of the water heater is able to completely eradicate the problem of the lack of hot water in the apartment, in a private home or at the cottage.

Types of equipment for water heating

Water heaters are storage and flow. Their advantages and disadvantages have both types, and before making a choice, ask yourself one question in favor of either option: "How often do I need hot water" If the apartment (at the cottage) home to one person and the need for hot water arises only a couple of times a day, or even rarer, it makes sense to pay attention to the flow-through water heater. For a family in two, three or more people need hot water all the time, in this case, buying a storage tank, it is also a boiler, will help you.

Installing the instantaneous water heater

Instantaneous water heater - heats water instantly

Instantaneous water heater is good in that it occupies a relatively small space and provides heated water immediately, after a couple of seconds after turning it on.

But do not forget about the negative side,namely the flow heater is not very economical in terms of energy consumption. So an hour of using your meter "wound" not less than five kilowatts.

The operating principle of the storage water heater

This heater has a tank, it is also a reservoir,is filled with water. Water enters the tank and cold under the influence of the heating element is heated to the temperature set on the thermostat. The reservoir has a special structure, and a layer of air between the existing walls of the tank, the water does not cool down quickly. heating time - up to one and a half hours. During the day, the thermostat itself starts water heating mechanism, so, in fact, is maintained constant set temperature.

Cons: tank volume and takes the place of the water is not heated so quickly. Obvious advantages: low power consumption, only 1.5 - 2.0 kW per hour.

How to install water heater

With instantaneous heating less hassle ininstallation. The main work - installation of the machine and the laying of a powerful three-core cable (cable is laid directly on the shield). The wire can be run under the skirting or punch indent in the wall, lay the cable and seal the cement screed (or starting putty) intervention in the integrity of the wall space.

Installing the water heater: scheme

Installation of storage-type water heater takes an average of one and a half hours from the experts. If you are not a professional in this case, the installation will take a little more time.

Important to know: water heaters up to a hundred liters of water can be easily mounted on the wall, but the boilers of more than 150 liters manufacturers recommend to put on the floor, not hanging them on the wall.

For ease of maintenance boilers must be not less thanthan 30 cm above the floor surface positioned. Usually mounted tanks, if it comes to a city apartment, the toilet over the toilet. The height of the mount is calculated so that the most stalwart member of the family does not cling nape bottom of the tank, using the toilet.

The set always go the anchor bolts «L»shaped 2 - 4 pieces (depending on the bulk tank). Mounting begins with mounting anchors to the wall. They are fixed at a certain distance, and often producers invest paper label for easy scribing, wall. If that is not attached, the distance measured by tape on the rear surface of the tank.

It is important to know: wall must be strong, durable, and ideally it should be a concrete surface. If the surface is crumbling and drilling holes pieces of the wall fall out, anchors require greater length. On the weak weak surface is impossible to mount a tank!

The drilled holes are insertedplastic tubes and then screwed into the anchor itself. Hangs an empty tank and checked for stability (it has to sit tight on the anchor). What follows is perhaps the most important part: the electrician and cut into the pipe.

Connecting the unit to the water supply

At the bottom of the storage tank has twooutputs for connecting to the pipes, one output red, another blue (respectively for connection with hot and cold water). The first step is to fasten the door to the blue safety valve, it always comes.

If the safety valve for whateverreason was not in the configuration, it can always be purchased at hardware store. Without it, you can not operate the water heater because it is the valve bleeds the excess pressure of the water in the tank.

On the safety valve screwedBronze check valve, its aim is to prevent the drain water from the tank back into the system plumbing. Then, tightly fasten two ball shut-off valves on the red out of the tank and check valve on the blue exit. Important: Always use tape "Fum" or tow for maximum tightness.

By pipes and boiler mixer can be attached orusing a metal-plastic pipes using flexible liner or the desired length. Choosing the latter, consider the fact that not all the fittings are able to withstand high pressure. In any case, flexible connection, even the best quality, inferior to a metal or metal-plastic pipes.

If you are staying at the metal-remember: it can not be bent! To connect the various sections of such pipe fittings have to buy the corresponding section (corners, connectors "barrels", etc). If the pipe to bend, fold in the ground soon, it will leak.

To help the handyman! Metal-plastic pipes are of two types: seam and seamless. Seamless and suitable for hot and cold water, and the suture (suture can be considered on the slice, it is located on the inner surface of the pipe) suitable for cold water only.

How to connect the water heater to the mains

As we have said, for flow heaterslaid a separate cable. The socket can not include them (wiring not survive). Cumulative same boiler can be turned into a wall outlet, but with one condition: in the socket must be inserted only one male - from the water heater. No other electrical appliances must not be connected further, especially through the "tee".

Ideally, the same should be kept separatewire to the main visor and enable (disable if necessary) boiler "automatic". In the case of water overheating in the tank clicks into place, ie, the "machine" disables itself boiler from the power supply. Overheating of the water may occur due to a fault in the thermostat. The machine is always recommended to install, as only it can protect housing from the wiring of fire due to a malfunction or a boiler overheating.

Typically, the heater wiring diagram, inthe most accessible of its kind, is offered to the buyer in the form of a drawing and instructions and supplied to the boiler. Also in the kit should include spare magnesium anode, bronze adapter and a safety valve. Everything else to buy separately.
