How to choose the boiler for heating water , proper installation

Boiler for water heating equips hot water in the right quantity, that is valuable for apartment dwellers, where seasonally disable hot water, and for homes that do not have a centralized hot water flow.

Boiler can be:

• accumulating (collecting water and heats it),
• flow (heats the water that flows through it),
• self-leveling (in his water poured by hand, so the model is in demand in the villagesand in the country).

source of energy for the boiler can act as gas and electricity, but in most cases the home is purchased electric model.It is less power, requires summing up the flue gas pipes and devices, and costs less.

boiler design provided a special tank, which receives cold water.Due to the work of heating element heats the water, climbing up.From the top of the tube, it is drawn that supplies hot water in the mixer.

Boiler works with a temperature range of 45-85 degrees.

All boilers have a thermostat that performs temperature regulation function.It is complemented by a thermometer showing the temperature inside the tank.The thermostat switches off the heater when the temperature reaches the set parameters, and as cooling water again includes a heater.

Asking the water temperature can be manually or by means of electronic control.

All the advantages of the boiler appreciate people who are faced with the lack of hot water centrally.Such a device makes it possible to always get the hot water for your needs.Each type of heater has its own advantages and disadvantages.

boiler heats a large volume of water and spends less energy than a flow.

Outs the storage heater are large size and slow water heating.

Moreover, it heats water when it is not required.A desire to save money, because of which the user reduces the temperature mode or disconnects the device regularly, can cause rapid damage and the appearance of an unpleasant smell of water coming out of the unit.

main advantage of flow-through water heater is its small size, making the device easier to place in the room.This boiler can be installed under the sink in the kitchen or above, as well as in the bathroom or inside the wall (concealed version).He quickly heats water, but drawback is that it consumes a lot more power than the cumulative option.

The inlet The inlet boiler is the best choice for the countryside.Its ergonomic tank, and such a device is inexpensive.

The downside of this type of boiler is a risk of overheating PETN.

most commonly purchased boilers with cylindrical form, having several advantages:

• compact size,
• long maintain the water temperature due to the fact that the hot and cold water in contact inside the tank with a maximumarea.

There are heaters, Sliema - their shape is more elongated and thin.Due to the reduced cross-sectional area of ​​such a boiler output gives more hot water.Moreover, such a device takes up less space, but it should be more than usual boiler slim cylindrical.

You can also purchase a rectangular cylinder, which easily fits into the interior in small spaces.This boiler can even be hidden in a cupboard in the kitchen.The cost of such boilers is also high.

If space very little, have to buy a boiler horizontal form, which is mounted under the sink, on a shelf or even on the ceiling.However, to save space of your electricity costs would increase, since the output of the hot water heater like a pretty low.

also should ask when buying a heater capacity, given the purpose of the device.

determine the amount of water that is needed daily to your family, you can select the desired volume heater (it can be from 5 to 400 liters):

• for 1-2 people is enough devices of up to 50 liters,
• 3-5 persons - volume 50-100 liters.

Material Material quality directly affects the duration of the product life.In boilers models who buy most often, the enamel coating inside.Such heaters are inexpensive, but also damaged due to high temperatures they are faster.

If the tank is made of stainless steel, such a boiler more durable and resistant to corrosion, but because of the subtlety of the walls it is more sensitive to changes in pressure in the water.

Modern heaters can be provided with thermal insulation of the tank, through which heated water maintains its temperature longer.The presence of such thermal insulation will reduce spending power and extend the life of the system, turn on and off the device.

insulation most often carried out by using polyurethane.Even when the 3-cm layer of heat loss device DSA are reduced to 25 degrees, and if the insulation layer will be 7.8 centimeters, the daily heat loss will not exceed 5 degrees.

to the operation of the boiler did not have problems, it is important to comply with such safety conditions of its use:

• never include the device in the network if there is no water inside;
• any manipulation (eg draining) performed only after disconnecting the device from the mains and cutting off the water;
• should take care of a good wiring that will withstand the load, as well as grounding.Well, if the boiler is connected to the network through the RCD;
• important that the boiler present an opportunity to drain the excess water;
• with unstable water pressure Pick up a model which can withstand 9 bar.

Any boiler there is a problem of scale formation and destruction by corrosion, especially if the water entering the device has a high rigidity, and the inner surface of the water heater you purchased is enamelled.

to ensure the protection of the water heater scale, manufacturers add to the device special anodes (magnesium rods). Their main effect is to dissolve salt deposits on the PETN.During operation it is important to regularly clean the boiler and check the status of the anode, replacing it with a new, if necessary.

heater can be represented in an electric boiler two types:

• wet,
• dry.

Wet type is also called immersion, as it is located right in the water (it looks similar to the kettle).

cons of this type are frequent breakdowns, tendency to overheat, damage and corrosion.

Plus Wet PETN - low cost.

Dry type of heating element is protected against ingress of water from the glass tube or ceramics.It is more resistant to corrosion, durability and reliability, and cost but had much higher than wet.

From the power of the device depends primarily on how much water will be heated quickly.

Before installation, make sure that the boiler will fit in the planned space for him, all the pipes are located in the convenient access and tools collected by hand.Try to imagine the installation process to the general scheme has helped you in your work.

Boiler installation according to the method is:

• wall,
• floor.

floor model is most often represented a large volume boilers and small devices are often mounted on the wall.We will focus on the installation of wall heaters, since they are more common.

Procedure:

1. Shut off the water.
2. Secure the boiler on the wall.There can not do without a partner that will help mark the spot first device location, and then hang up the device.
3. From the boiler will depart flexible pipes - one of them is a pipe, the supply to the device the cold water and the second will take the heated water.On the feed pipe is to install a special valve for the possibility to block the water that enters the boiler.This valve is useful to you, when you come to clean the device or turn it off for a while, drain the water.
4. verify the reliability of fastening the unit on the wall, each tube is connected at one end to the heater (do this is not very tight) and the other end - to the water supply.
5. To verify the installation, you open the water supply valve and check for leaks places.
