How to switch the boiler to summer mode

What is a convector

The market offers a variety of types, where it is quite easy to get confused. Oil radiator, electric convector, infrared radiators, my head goes around from the range and price offers. Our review we will devote to the electric convector. Convector principle of operation is based on the physical properties of heat transfer from the heat transfer medium, in our case from the heating element to the heated room with the help of internal energy, which is transferred by jets and streams, that is, by means of convection.

In simple terms, the convector has a heating element built into it that makes the air around it hot. H aggressive air begins to move upward, making room for cold air currents. This “circulation” is called natural convection. We hope we have answered the question of what a convector is. clearly, with this simple process will help you understand the picture:

Operating principle of the electric convector

As we can see, the electric convector has a simple principle of operation. By the way, since the movement of air is due to convection, the device does not require additional equipment with a fan, so the electric convector, earns a plus in his piggy bank. Of course this is not the only advantage, that makes us choose the electric convector for heating to ensure a comfortable climate in our apartment, but first things first.

boiler, summer, mode

Operating principle 2x circuit boiler works in 2 modes: heating and water heating. However, the device can not perform these functions at the same time.

So, in order to turn off in the summer only the coolant circulation through the pipes and radiators of the heating system should simply shut them off so look for and shut off such a valve on the main thick pipe going from the boiler up and look somewhere above the plucking in the boiler tee), in this case the

Q&A

How to choose the correct capacity of the boiler? 1 kW equals 10 m2 with ceiling heights up to 3 meters. For example, if you have a house 240 m2 and the ceiling height is not more than 3 meters, the boiler power should be at least 24 kW.

What does it mean a boiler with a closed combustion chamber (turbo) and an open combustion chamber (non-turbo)? Open combustion chamber means that the combustion products of the gas boiler is carried out in the chimney (fireplace). The flue duct should be made of stainless steel, as the temperature of flue gases is low, which leads to condensation and destruction of brick chimney. Closed combustion chamber (turbo) means that the exhaust of the combustion products is carried out with the help of a fan built into the boiler and a coaxial tube tube, the inner pipe diameter of 60 mm are forced to exhaust combustion products, and the outside pipe diameter of 100 mm in the natural way the air flows to burn the boiler.

What is a single-circuit or double-circuit boiler? Single boiler is a boiler that can only heat the room. Two-circuit gas boiler is a boiler that heats the room, as well as prepares hot water in a flow-through manner.

What does winter-summer mode mean in the boiler? In winter mode the boiler operates both for heating and domestic hot water preparation. In summer mode the boiler operates only for warm water preparation.

What is a room regulator for?? Room regulator serves for the boiler to work on the temperature of the air in the room, which allows you to create a more comfortable temperature for you, as well as reduce gas consumption by 25%.

What do you need an outdoor temperature sensor? The sensor of external temperature allows creation of equithermal regulation in the boiler, i.e.е. Depending on the outdoor temperature, the boiler automatically selects the right output for operation, which saves 10% of gas.

How to choose the right expansion tank for the heating system? The expansion tank serves to stabilize the pressure in the heating system. Expansion vessel is selected according to the volume of water in the heating system, namely the expansion vessel should be not less than 10% of the volume of water in the heating system. For example: if the heating system has 70 liters of water, then the expansion tank must have a volume of at least 7 liters.

What function does the accumulating tank perform in the heating system? Accumulation tank is installed with solid fuel boiler. When the boiler is working, part of the heat goes to heat the house, and another part goes to the storage tank. When the fuel in the boiler is burned out and there is no time and possibility to continue the loading of fuel, the heat from the accumulating tank is spent on heating the house. It is also possible to install an electric heater in the accumulation tank, which allows you to maintain the temperature at home during periods when there is no possibility to heat the boiler.

How to avoid overheating of the solid fuel boiler? Most often, the overheating of the solid fuel boiler is due to the power outage, when the circulation pumps stop working. If there is a central water supply in the house, the problem is solved by installing special safety valves Caleffi 544 or Regulus DBV1. When it reaches 95 ° C at the outlet of the boiler, the valve opens the access of cold water from the water supply to the heating circuit in the return line and at the same time there is a drain of overheated water from the supply line.

Types of heating boilers

Scheme of gas boiler circulation system.

The range of modern equipment, which can be used as a heating element in the heating system, is extremely wide. In the market of boiler equipment there are different models from manufacturers of different countries. However, all the variety can be divided into two categories according to the type of installation (wall or floor) and the type of construction (single-circuit or double-circuit).

Wall mounted gas boiler is more compact than the floor standing gas boiler, which often requires a separate room (boiler room). The division of boilers by the number of heating circuits indicates their functionality. In the first case, the gas boiler is used only for heating, while the second has two built-in heating circuits, so they are also used to provide hot water. Both circuits work independently of each other, that is, if you need to heat water, it does not affect the efficiency and quality of heating.

Removal of air from the heating system

Sometimes it happens that all attempts to adjust the boiler temperature does not give the desired result. This occurs mostly in the fall, after a long summer downtime of the heating system.

Vaillant Boiler Control

When the cold weather comes, the consumer starts the boiler, it starts working, and the radiators are heated unevenly. the sections closest to the boiler are somehow heated, while the subsequent ones become slightly warm, if not cold at all.

This can happen if before the first start of the boiler in a new heating season the water level in the heating system was not checked. Warm summer days warmed by the sun the water evaporates from the system, the process lasts all summer and by the fall the level of the coolant in the system can drop below the minimum mark.

After the first start-up the circulating pump starts “driving” the water through the system and forces some air inside the heating. Pushed by water, it accumulates at the highest and farthest points of the system from the boiler.

There is a “choke” in the system. a cork of accumulated air does not allow the coolant to fill the radiator to the end.

To solve the problem, the Mayevsky tap should be screwed into the top part of the radiator on the side farthest from the boiler. The device is designed to remove air from the radiator.

When you turn the valve head with your hand or a screwdriver, an indirect through passage opens to remove air. a hiss of escaping air appears. As soon as the first splashes of water start to come out of the tap, it is closed.

During the first 2-3 days of heating operation it is recommended to perform several such operations with an increasing break between them.

Before opening the faucet Maevsky should be placed under it an empty bucket or other suitable container. It is advisable to place between the faucet and the wall any protective screen of cardboard, paper, fiberboard or other materials to protect the wall covering from splashing water.

As a “disease” of the heating system, leaking is typical for large heating circuits due to possible unauthorized extraction of hot water from the heating system. Therefore, in apartment buildings, the procedure of bleeding air from the heating system may be needed several times throughout the heating season.

Starting the boiler

After completing all installation work and pressure testing, the first adjustment start-up of the boiler equipment is carried out. All the works are performed by the service center workers with the corresponding documents, which in the future will save the warranty of the manufacturer.

Starting the boiler Navien, the instructions must be followed flawlessly. Sequence of work:

  • Fill the circuits with water through the make-up unit of the unit, built into the design, with a special tap at the bottom next to the tap water inlet.
  • Watch the pressure gauge when the pressure rises to 2.0 atm, the tap is closed.
  • Remove airlocks. At the first start perform in manual mode, and at subsequent. through an automatic system. Start the process with the most distant battery, opening the faucet Maevsky, one by one passes all points of the heating circuit.
  • After weeding out the air lock the pressure in the circuit will drop, so you need a second make-up.
  • Drain the air mixture from the circulation pump.
  • In order to turn on the unit, press the Power button.
  • Electric ignition will work and the unit will start, after which it is necessary to set the temperature mode.

Characteristics and operating principles

Gas boilers, as well as other water heating devices, are designed to heat the coolant. As a rule, it is water, with the heat from the combustion of gas it is heated and subsequently used to heat the premises. If you install such equipment in a private home, you can forget about buying wood and coal, which have to spend a decent amount of money.

As fuel used natural or liquefied gas. There are two reasons for this:

  • Gas is quite cheap, which allows you to heat residential and non-residential premises with minimal costs.
  • The use of gas allows the use of automatic control systems and fire safety, which makes gas boilers safer.

How the gas boiler works

Although such equipment may have different design, the principle of operation is the same for all. Using a match, or in modern equipment by means of electric ignition, the igniter is ignited. This small wick burns continuously.

The gas is then automatically fed into the combustion chamber and, once burned, heats the water. The coolant is heated to a certain temperature, then the fuel is shut off. As soon as the water temperature has dropped to low levels, gas is again fed into the combustion chamber and the water is thereby heated.

If there is no technological necessity for the direct use of water steam, it is advisable to convert the steam boiler to water heating mode or replace it with a new water boiler.

Payback period for boiler transfer from steam to hot water boiler is one to two years.
