Accumulative and instantaneous heaters

This appliance is used to heat water in private and holiday homes, as well as apartments. Its type and size depends on the number of living people. Having at least some elementary skills in plumbing, you can install a heater at home without professional help, and enjoy savings and comfort. Storage capacity installation of alternative sewerage.
When selecting a heater need to define the main parameters:

Power source
Principle of work
In turn, they are divided by a power source-gas and electric, and the principle of work is cumulative and instantaneous.

The process of water heaters

Accumulative

In this case, the machine heats the previously typed into the tank water. Most of these heaters are equipped with an electronic system, and automatically turns off at a preset temperature, which is then stored for a very long time. This species is very popular because of the low prices and the lack of special installation conditions.

Flow-through

The name speaks for itself. The water passes through the heater to the tap and in the process reaches a temperature 30°. The heating is carried out using a special bulb with an electric heater. This type of heater is not so abundant, because that requires a lot of electricity, respectively, in older homes did not install. They can also be divided by type of heater is coiled and TENG. There are nuances. TENG at 10-20% less spending power, compared with spiral. But it is better to use spiral where hard water, which is now in almost every house.

Installation of water heaters

The stages

System type does not affect the process of connection. Everything is so smooth, it must be mounted according the rules and instructions of the manufacturer and the General conditions for plumbing fixtures.

As in any job, you must first prepare the workspace to create the necessary conditions:

The device must be easy and free access, but does not interfere with the work process;
Check and make sure that the wall you intend to mount the tank is strong, has a sufficient thickness for fastening and can endure the double workload. For example, if the volume of 50 l-power wall must = 100 kg;
Check pipes and risers, their quality, dependability;
Rate the quality of the wiring in your home. Is there enough section and the power it has. If the wiring is old-it is better to replace the prior to the installation, after all the work starts to punch out the light.

Tools and instruments

After the full scan options described above, must be placed to stock up on essential tools and some materials:

Hammer drill;
Tape measure/ruler
Keywords (spanner and adjustable)
Screwdriver (Phillips and flat)
Flax tow and paste/tape fum
The area of metal-plastic pipes (some estimate in advance)
2-3 switch off the tap (depends on the type of heater)
Two or three tee and a pair of connecting hoses

Storage water heater

Installation

It’s simple and familiar: the chart to fit the appliance places for drilling on the wall. If you can, before you drill the holes, place the heater and try on, whether we agreed with markup. Now the wall in two or four places (depending on your design). Next, roll out the dowels or thin walls, insert bolts through the wall, and give the bar.

Important: the distance from the upper holes to the ceiling should be more than enough, so you can then hang reservoir.

Connect to water heater

Once our machine hangs on the wall begin to connect. Greatly facilitates the work of inferred connections. Then you can just use the tees and join our device with the risers and pipes in the apartment. For sealing joints in flexible hoses, use a rubber ring gaskets. There are two valves on the device: blue-input (cold water), red-output (hot water). Also the input pressure relief valve is mounted and drain the water from the tank. It can be connected between the hose and the input or through a blue tee-what is recommended. Here integrity means using tape fum or winding a tow with the paste.

Check

The latter connects to the faucet and hot water pipe. Next, open all faucets and faucet and see to it that came out all the air from the heater. Also inspect the connections for water tightness.

Connect to electricity

The last step is to carry out electrical wiring to the heater. This is a 3-wire cable, where the Brown and blue wire-phase (A) and zero (N) respectively, and the yellow (or any other color) is grounded. After that, turn on the electricity-red activity light should light up. Now adjust the desired temperature. All! Can use the device.

Flow-through water heater

This type of heater takes up very little space compared to the previous. It can be installed even under the sink in the bathroom or kitchen. However, the requirements of this unit is much higher. First of all, this refers to posting-cable cross-section must be at least 4-6 mm², at least 40 and counter; It is also necessary to install a circuit breaker-32-40 (a).
There are two types of installation: temporary and permanent.

Temporary

To connect the heater to the shower hose. And for entry of cold water in the device crashed tee with shut-off valve in the pipe. Then open the input and output devices and check the tightness of connections. After about 30 seconds to get the hot water.

Stationary

The bottom line is that your water heater will work together with the central system. There are two hot and cold water pipes. More tightly connect the valves. The next stage is similar to the method of connection heater savings. Through the shut-off valves connect the input and output (blue) (red) of the device. Also check for any leaks. Open all taps and faucet, get hot water. Hot water risers should be close to your heated water didn’t go to use pipes of neighbouring apartments.

All electric water heater can be divided into two groups: heaters instantaneous and cumulative i.e. capacitive heating principle, all water heaters are instantaneous and cumulative. What is the difference between them, the principle of heating the water in the machines is a flow or cumulative, they seem to be similar, but the savings are larger than instantaneous.
