Step by step chart to connect the indirect heating boiler

centralized hot water - more myth than reality.In most communities the benefit of civilization is no longer to be available for many years.But there is a great alternative - water heaters, boilers, they are the same.On sale are available many models of such units: flow, storage, electric, gas, etc.

Step boiler wiring diagram indirect heating

And if you connect the gas vodogreek must deal specially trained people, the electric heater can be connected to the water on their own.The guidance will help you thoroughly understand all the subtleties and nuances of the event.

circuit Preparing the connection heater

Choose a location for the unit.It is better to have free access to all the connecting elements of the system - so it will be easier to carry out maintenance of the equipment and carry out repairs with the appearance of such a need.

If you select the cumulative model heater, make sure that the wall can withstand the weight of the water.Subtle interior walls and plasterboard walls with this problem is definitely not right.

Install water heater in close proximity to water pipes - so you need to save yourself from laying additional infrastructure.Therefore, the ideal place for the installation of the boiler is a bathroom.

Important!The heating elements are electric boilers have a high capacity.On average, it is about 2 kW.That in future no problems with the wiring, experts recommend to connect this kind of equipment directly to the distribution box, using copper wire as possible with a large cross section.The closer to the shield is installed boiler, the need to use less wire.Understand and this moment.

selecting a place for installation of the heater, proceed to the preparation of tools and related accessories.

10. more pipes.Buy if necessary.Be sure to check with the seller, can the pipe you have selected to withstand operation in future conditions.

To install and connect the boiler

ready to install the boiler.Put the water heater to the site of his future placement on the wall.The distance between the tank and the ceiling should not be less than 100 mm, otherwise you will not be able to hang the unit on the fasteners.

cylinder capacity l	approximate load on pulling kg	wall material	Recommended bolt diameter mm	Recommended bolt length, see
30-50 liters	15-25	Concrete	6-8	6-8
30-50 l	15-25	brick / cinder block	8-10	8-10
80-100 l	25-35	Concrete	8-10	8-10

150-200 liters	45-60	Concrete	10-12	8-12
150-200 liters	45-60	brick / cinder block	12-14	12-15

Schedule with a marker or pencil attachment points.Do this carefully.If the tank is big and heavy, invite the assistant.

Drill holes and screw fasteners.Usually they are included with the tank.If the fasteners are not available, buy them separately.Suit steel hooks.

Before installing the water heater, make sure the integrity of thethreaded connections for water inlet and outlet.Experts note that the hoses and the relief valve often unscrewed 1-2 turns.If you too have found such a defect, carefully drive out the thread die of half an inch.Screw the valve or hose force is not necessary.

Replace the boiler 2 separate overlapping crane.Examine the appearance of the output thread: blue must be connected to the cold water through the red will leave the heated liquid.Apply sealing tape, screw the relief valve on the cold water inlet and connect to the water supply system, a convenient way (using pipe or hose).Experts strongly recommend the use of flexible hoses, especially in apartments.

Apply cold water to the boiler.At the same time, open the valve on the hot water - so you bleed air from the system.

At the end will only have to connect the boiler to electricity.

water heater is not recommended to simply connect the heater to the nearest power outlet through a cheap power strip.Although in practice most do so, such an option connection is not secure and correct.Once selected, the responsibility for possible trouble will lie to you.

tank is recommended to connect a separate branch of the switch box.A branch need to be equipped with an automatic shutdown.Recommended machine capacity - 16A.To connect to the mains supply must be removed with a wire heater factory and have instead a new cable from the panel.For wiring, use a three-wire copper cable 2.5 mm2.

heater necessarily need to be grounded.The lack of protective earth faces a lot of trouble.If light "bite" shock while taking a shower you can still survive, the total wiring failure and fire - a situation far more tragic.

tank Ground follow straight to the distribution switchboard.If you do not possess the necessary skills for this, have a qualified electrician.To ground is also recommended to use copper wire.

Nuances connect the boiler to the pipes of different materials

Depending on the material of manufacture of water pipes, the order of tapping water heater will be somewhat different.Check out the existing nuances, to get the job done most efficiently.

Connecting to polypropylene tubes

If the pipe is not hidden in the wall connecting the boiler will not have any difficulties.All work is to ensure that you cut the water supply pipe in the right places (depending on the installation height of the tank), soldered into the prepared hole tees, and have them spend the pipe to the heater.To connect with cranes use a conventional clutch.

little more time and effort you spend on a connection, if the pipes embedded in the wall.In this situation the procedure is as follows:

• opened pipe;
• carried Box scheme discussed above;
• output connections;
• pipe closed back.

connections are made via tees and detachable sleeves.Wait until hardening soldered joints, connect the connectors and connect the boiler to the water supply.

Connection PVC Pipes

technology does not allow to mount plastic pipes hidden way, with a hole so no special problems will not arise.

is enough to cut the pipe, insert tees and bring water to the elements vodogreyke.This Box is complete.

connection to steel pipes

most complicated case.In this case, the tank will be supplied through the kitchen faucet connections.Each outlet on the need to wear a tee - it will connect the boiler and the kitchen faucet to a single tube without slicing thread.

Useful tips from professionals

There is some important nuances, without the knowledge of and compliance with which the boiler water supply connection is incorrect.You should know that the hot water system do not need to complement any additional elements, except shut-off valve.It is installed on the boiler tube.

Socket as cold water is installed after the preliminary mounting tee.Crane for removing excess water from the water heater cold cuts in the side outlet of the splitter.It is also connected to the tee of the return valve and shut-off valve.Last connected to the water supply.

When connecting the tank to the water shall be prohibited to do the following:

• open the protective window when the heater;
• feel empty boiler.Pre-need to fill the tank with water, otherwise the heater may burn;
• drained, without turning off the pre-heater;
• complement vodogreyku parts from other boilers.The exception is the same model as well as tanks with compatible parts.

Brief important: safety valve

deserves a separate section of an element of the system as a safety valve.It eliminates the possibility of leaving fluid in the return water, and promotes the normalization of pressure in the system by discharging excess water during its heating.

important caveat: Do not install a check valve in place of safety.Because of this temperature switch may malfunction, causing the boiler to explode.

Installing the safety valve is performed in place of cold water inlet to the heater.Connectivity technology prohibits placing the locking elements between the entrance to the tank and safety valve.

Important!Keep an eye on the state of the valve during the operation of the tank.If the brass device for a long time remains dry, this may indicate a malfunction.The failed unit must be replaced as soon as possible.

Now you can connect the heater to the water supply in compliance with all the requirements and nuances of technology.This is a great opportunity to save on plumbing services and to keep the whole process under the personal supervision.

Successful work!
