Scheme of connecting an electric boiler to the network
Before connecting an electric heating boiler, it should be noted that the electric boiler must be connected to the network through copper wiring. The cross section of the wire must not be smaller than the one indicated in the document that came with the device. The electrical connections of the external type device must be made through special cable outlets. These conclusions should be located in the lower left corner. There should also be a brass ground terminal with an M6 size bolt.
Power cable connection diagram
During the insertion of the electric boiler into the heating system and the installation of grounding, it is necessary to ensure that good and reliable contact is provided between the metal case of the device and the brass bolt. Before connecting the bolt to the frame of the device, you need to thoroughly clean the junction.
If electric heating is planned to be organized for a building with a large area, then when purchasing equipment, you need to choose one that provides for the possibility of installing a cascade. In order for the devices to work properly in a cascade, the terminals of the control device must be connected to the unit that is controlled. If the system setting is controlled by a room type controller, then the control contacts must be connected to the terminals of the control device.
Scheme of the electrical heating system of a two-story house
The device must be visually inspected to make sure that it is in the correct position, the water pressure in the system is normal, and all communications are connected. All this is defined in the documentation of the unit.
After that, the installation scheme for an electric heating boiler involves the following steps:
- It is necessary to check the serviceability of the pipeline fittings located in front of the unit. To do this, you need to switch it from the "closed" to "open" position, and vice versa.
- All pipeline fittings of the electric heat generator are transferred to the "closed" position. It is also necessary to transfer the pipeline fittings of the water supply system and the heating system to this position.
- On those pipelines that bring cold water to the unit, you need to open the shut-off valves. If an electric heating system is used, it is not recommended to use antifreeze liquids for it. This is because they have properties that can affect the operation of the equipment in a negative way. Anti-freeze fluids have a composition that can cause aging or rapid wear of rubber components.
- It is necessary to install a sump or filter before entering the unit on the return pipeline. You can install both of these elements.
- After the heating system is completely filled with water, it is necessary to check how tight it is.
When the installation of an electric boiler with heating radiators is completed, it is necessary to check how efficient the sensors of the system are. These include such sensors as: temperature controller, water pressure sensor, signal and control components of the unit, emergency type temperature sensor.
During repair of the heating unit or during unfavorable installation conditions, it is possible to connect an electric heater using rubber hoses.
For the heating system, it is necessary to use water with a minimum hardness index. Then the service life of the heating elements can be significantly extended.
Choosing a place to install a thermal electric generator
It is best if the installation of an electric heating boiler is carried out in a non-residential premises. For these purposes, the kitchen will be an excellent place. The generator must be located in a location that is convenient for both installation and maintenance.
If you install the generator in accordance with the standards, then it is necessary that at least 5 cm of free space remain from its sides to the wall. There must be a free space of at least 70 cm in front of the device, at least 80 cm above the device, and at least 50 cm below it.
One of the options for installing an electric boiler is on the balcony
The heat generator must only be installed on a wall that is built of non-combustible material. To carry out the suspension of the device, you must use a special mounting plate. Such an element should be included in the basic package of the device. The plank must be attached to the wall with 4 dowels.
The electric boiler heating connection diagram implies that another membrane-type pressure compensator will need to be installed in a more capacious heating system.
Types of electronic thermostats
- Daily thermostat. This thermostat maintains the temperature in the house, according to the specified parameters. For example, if the temperature you set is 26 degrees, then the thermostat maintains this temperature in the room for 24 hours.
Programmable (weekly) thermostats. The weekly electronic thermostat for heating can be programmed depending on the tasks facing the user. You can set temperature modes in a certain time interval, set night or day temperature, etc. For example, a user lives in the city for 5 days, and comes to a country house for 2 days. Then, on the device, he sets the temperature to 10 degrees from Monday to 18-00 Friday, and from 18-00 to Monday, the temperature in the room is at 26 degrees. You can also individually adjust the electronic thermostat to change the temperature during the day, for example, from 9-00 to 18-00.
Wired and wireless thermostats. The wired thermostat is connected directly to the control device (boiler, pump, three-way valve), and the wireless thermostat communicates via radio signal with the receiving unit located near the controlled device (due to this, there is no need to “stretch” the wiring through the whole house).
Internet management. Some thermostats for a heating boiler allow you to control it via the Internet (turn it on / off, set temperature conditions, etc.). For example, the Internet is the Salus iT500 thermostat, which can be bought in the online store here.
There are other variations of thermostats and thermostats. If you decide that you need to buy a thermostat for heating, then you must first decide on its functionality. For example, in the absence of the Internet in the country, you can use the remote control of thermostats using a GSM smartphone.
The GSM module plays the role of your personal assistant - you called him, gave him a command, for example, to pre-heat hotter by a certain time - and the whole family will come to a warm and comfortable house. Or vice versa: forgot to turn down the boiler power in the morning, leaving for work - it’s not a question, you can do it right from work, via the Internet or directly from your smartphone, while you still get to work
The GSM module is a compact device with its own SIM card of any operator (it is important that it provides reliable signal reception in the given area), which allows you to control the indoor climate from any phone (satellite, mobile or fixed-line), tablet or PC.This is essentially a computer docked with external sensors and having the ability to change the operating modes of the heating system
Naturally, the module must be in the zone of reliable reception of mobile operators.
In this section you can buy thermostats for the heating system from leading manufacturers: Thermostats of the KROMSCHROEDER company (Kromschroeder), which occupies one of the leading positions in the world as a manufacturer of equipment for controlling gas supply, controls and measuring equipment for gas supply and heating systems. Kromschroeder also produces: programmers, regulators, valves, pressure sensors, instrumentation and automation, burners, equipment for heating systems. Salus Controls thermostats (Great Britain) are designed to maintain temperature in heating, ventilation and air conditioning systems. There are many models of various price categories, functionality and design solutions.
Boiler programmer
- with its help, you can not only maintain a comfortable temperature during the day and choose the temperature for the night, but you can also set the economy mode for the time when you are not at home, for example, on weekdays, when all family members are at work or study. The accuracy of the weekly programmer is maximum if installed in the right place. This should be a living room in which there is a window and a heating radiator, then the place along which the heating of the entire area will be oriented will participate in both heat loss and heating. Installation in the kitchen is not recommended due to additional heat from the gas stove, and in the hallway due to the lack of heat loss and the large distance to the batteries.
Programmable thermostats for electric boilers
The most modern equipment is a programmable thermostat for an electric boiler.
The weekly programmer for heating equipment (both gas and electric) Auraton 2020 TX Plus is equipped with a convenient large informative display. It displays the following information: time, day of the week, temperature in the heated room, running program. This device does not require wiring for installation. The cycle of work is 7 days, the number of programs is 3.
Attention! The Auraton 2020 TXplus programmer is equipped with a temperature control sensitivity setting function within the range of - 0.25-1.0 0 С. The control range is 5-30 0 С
Standard programs provide for a comfortable temperature regime during the day and at night. The anti-freeze mode is used for mothballed non-residential housing construction.
The temperature controller is equipped with two programming cycles:
- from Monday to Friday, 4 temperature switching points per day can be set;
- on Saturday and Sunday - two switching points per day.
Attention! The programmer is equipped with the ability to change the communication code. This feature eliminates interference from other nearby wireless equipment.
Auraton 2020 TXplus thermostat installation rules:
- The device must be mounted on an internal partition.
- The controller should be installed in a frequently visited room with free air circulation.
- Nearby should not be heat-radiating equipment - TVs, refrigerators, heaters.
Attention! Do not install the device in a room with poor air circulation and do not expose it to direct sunlight. These two factors may cause the programmer to malfunction.
Fluctuating readings can cause the device to be close to the door.
Gas boiler programmer
To simplify the management of a gas boiler and increase the level of comfort in the room, a programmer for a gas boiler is designed. Some models of gas boilers are equipped with programmers, for others it can be purchased separately.Programmers can be compatible with certain boilers or universal, suitable for all boilers or even air conditioners. The use of programmers for gas boilers has several advantages.
1. The programmer reacts not to the temperature of the coolant, but to the temperature of the air, and only after it drops to a certain level, it gives a command to ignite the boiler. Gas savings come from:
- a break in the gas supply circuit, the boiler does not turn on every 5 - 15 minutes to check the water temperature;
- the ability to program the device for different temperatures at different times, which will allow you to heat the room less intensively when no one is at home or at night.
2. The temperature in the room is measured continuously by the thermostat, which allows you to keep it at the proper level. As soon as the temperature in the room drops below the maximum permissible value, a signal is given to turn on the boiler, as soon as the temperature reaches the required value, the gas supply is shut off.
3. The minimum value of the hysteresis will make it possible to make the temperature difference between the boiler turns on minimal and not noticeable to a person.
4. Almost all models of programmers have factory programs and the possibility of self-programming for the needs of a particular family. The weekly cycle of the programmers allows you to set comfortable temperatures depending on the time of day, and weekdays/weekends.
For the normal functioning of the device, its location is of great importance. Based on this, you should strictly follow the instructions when installing it.
Comfortable and uninterrupted operation of the autonomous heating system largely depends on the correct selection of its components. The predetermining link, of course, is the heating boiler. It is a kind of "heart" of the system, ensuring its continuous operation. In order to provide the heating boiler with normal working conditions and to level the “idle” operation to the maximum, special devices are provided - programmers. which can be called the "brain" of the entire heating system.
The programmer controls the operation of the boiler, controlling its switching on and off, maintaining the temperature set by the user in order to create the most optimal and comfortable conditions for the user. Many programmers have the function of storing the given settings for the day, week, month, and also for certain days at the request of the user himself. The use of these devices is justified and cost-effective, as it allows not only to significantly save energy resources, but also to extend the life of the heating equipment used, ensuring its rational operation. As a rule, today the installation of any autonomous heating system is not complete without this small but very useful assistant.
Programmers from various manufacturers are widely represented on the heating equipment market, among which the products of the Polish company AURATON stand out for a number of indicators. This trademark may not be familiar to a wide range of consumers, however, among specialists in the field of heating technologies, it is quite well known and in demand.
The range of programmers for AURATON heating boilers includes conventional room temperature controllers as well as weekly programmers. There are both wired models and models controlled via a radio channel from an actuator - wireless temperature controllers and programmers. The choice of the optimal control device is a purely personal matter. Someone prefers standard wired devices, someone is annoyed by the presence of a large number of wires, then the choice is up to a wireless programmer.
The main difference between AURATON programmers and temperature controllers from competitors is the combination of high-quality components with high functionality of devices, ease of interface and control with an exquisite design.The presence of a display on AURATON programmers can significantly increase the information content and ease of controlling the operation of the device. The information displayed on the display of the device gives a complete picture of the state of the system and the set parameters.
Weekly Programmers Salus Britain
The temperature controller for electric boilers from Salus, model T105RF, is a wireless weekly programmer that allows you to set two temperature levels: “comfortable” and “economical” in the range of 7-30 0 С, in increments of 0.5 0 С.
For any day of the week, you can set one of 9 programs, 6 of which have hard factory settings, 3 can be set by the users themselves. The device is equipped with a large informative display with a blue backlight.
The programmer of this model can be used with any gas and electric heating units that have terminals for connecting a thermostat.
Attention! If several sets are connected at one object, then one of the 32 communication codes can be selected, which eliminates the mutual negative influence of the equipment. If, when choosing a thermostat, its cost plays an important role, then you can choose a cheaper wired model
If, when choosing a thermostat, its cost plays an important role, then you can choose a cheaper wired model.
Heat management with Auraton thermostats
The Auraton 1300 thermal device can be used with all types of heating units, convectors and infrared panels. This appliance is extremely effective in saving energy and improving indoor comfort. It is easy to install and operate - temperature control is carried out by simply pressing a button.
The LCD screen of the Auraton 1300 displays the following information:
- room temperature;
- the order of operation of the heat generator;
- on/off switch;
- battery indicator.
To ensure efficient operation of the thermostat, it is necessary to choose its correct location, it should not be placed near:
- air pipelines;
- heating devices;
- hidden pipes and smoke ducts.
Advice! The device must be protected from direct sunlight.
The principle of operation of the thermostat - when the temperature in the room falls below the set value, the heating device is turned on. The device screen displays the operating mode of the heat generator.
Connection Features
To install the device, you will need only two communication wires: power supply and a cable for connecting to the boiler automation. The entire installation process consists of the following steps:
- 1. Choosing the optimal location for the thermostat. You need to install it in a corner inaccessible to small children and pets. The level of elevation above the floor does not play a special role, although they usually try to set the programmers lower, because the heated air is lighter than the cold one, which means it is more logical to measure the temperature near the floor.
- 2. Next, technological holes are made in the wall for mounting the device. For this, an ordinary household drill is suitable, which every owner probably has.
- 3. Then the connection to the communications is made and the wires are laid. If the apartment is just being renovated, then they need to be hidden directly into the wall so as not to spoil the aesthetic appearance. Otherwise, you just have to pull the cable under the wall so that it does not get in the way under your feet, and there is no risk of accidentally hooking it.
- 4. After connecting, a test run is performed. It is necessary to ensure that all statements correspond to reality. You can then customize and enjoy improved system ergonomics.
How to connect the programmer to a gas boiler
After buying the device, the question arises of how to properly connect the programmer to the gas boiler. For wired and wireless models, this process is different.
When connecting a programmer with wires, you will need a cable with a cross section of 2x0.75 mm². The wire is laid open or hidden in special channels.
To power the programmer, AA batteries should always be kept in stock.
The wireless programmer is easier to install. It consists of two blocks, one of which is mounted in a room where the temperature will be controlled, and the other is connected to a gas unit and serves to receive radio signals.
When installing remote programmers, it is important to adhere to certain conditions:
- you can not place the unit in a place where drafts often appear or direct sunlight falls;
- do not mount near radiators and heaters;
- it is not recommended to install programmers behind a curtain or furniture;
- do not place near household appliances and electronics.
Installation must be carried out in accordance with the attached instructions.
Note! Remember that the programmer maintains the set temperature in only one room. In other rooms, depending on external conditions, the air temperature may vary
To make it easier to maintain a comfortable microclimate in all rooms, experts recommend installing the programmer in the coldest room or in a place where residents most often spend time.
The programmer is connected to certain terminals of the gas boiler board. To determine the connection point, it is necessary to study the circuit of the unit's electronic board printed in the instructions.
