Still, some 10 years ago for heating the same premises needed in 5-10 times more to burn fuel to get the indoor climate at the same level as now.Modern heating boilers, spend less fuel due to more efficient heat exchanger.The flue gas emitted barely warm.Therefore, for heating the coolant requires less fuel.When using modern boilers have to remake the chimney, asash are formed during combustion acids that because of the low temperatures remain in the flue channel and destroy it.To prevent this, the chimney should be insulated or made of corrosion-resistant material.



Modern boilers

modern gas boilers step further.Now they do and do not need a chimney, they use a system of forced removal of combustion products.Such boilers except for the fuel gas, electricity demand, which is necessary for them to the controller, which in turn, provides automatic, timely lit burner, controls the temperature of the coolant and hot water (if applicable).Typically, these boilers have in their arsenal a pump that circu
lates coolant is forced through pipes and radiators, which in turn increases the efficiency of the latter.These boilers set the bar "economical" to a new level.Nevertheless, and in such boilers have a number of its shortcomings, and Sami significant of these is dependent on electricity.Given that power outages are frequent enough and tend to occur in cold and windy weather, with ice and snow storms.Draw conclusions.Of course, for the urban dweller power outages scary, they were either not at all or quickly eliminate those.But for residents of small towns and villages, the element can become the number one problem.

Even if you have an economical, efficient boiler obtained from a heat to be distributed through the rooms of a house or apartment.For the distribution of the heat is used coolant, as is often serves water.Water is the most affordable, clean, cheap coolant.Can be used as products of water is steam, but couples often used for heating industrial premises.In order to keep the water gives up its heat to the room it is necessary to deliver and pass through the radiator.For delivery of water in the radiator is used, as you know the pipe.

pipes are different.They are made of iron, bimetal, stainless steel, plastic, plastic and methane.All thicket and often we used to see metal pipes.The newest development in this direction is "Ekoplastik".Unlike conventional plastic pipes, pipe systems "Ekoplastik" have a more complex structure so have a higher resistance to high pressure and temperature, and also have a lower heat transfer through its surface.Thanks to this energy does not dissipate until the coolant reaches the radiator.Such pipes can be embedded in the wall plaster.

And when the heat from the boiler to the room we were taken to the radiator, radiator must give to receive energy for heating the room.Radiator in Latin - "emitting", about 25% of the energy it gives in the form of radiation, and the rest in the form of - convection.Convection is translated from the Latin - "the offering and delivery."Radiator always in mind, this plays a significant role and its design.In other matters the design is not the most important parameter of the radiator.Perhaps more important for the radiator is its thermal power dissipation.The larger the size of the radiator, the greater its power.True, this rule does not always work.Various types of designs and materials from which the radiators are made in different ways give off heat.

heatsink should primarily bladeless, the consumer should receive not just warm, safe and warm.Although the temperature of the water that circulates in the radiator 90-95 C radiator cover must not exceed a temperature of 40-45 C. These measures are important for furniture and for electrical and for the child not have to worry.For the modern city dweller who spends at most 24 hours a day in his apartment it is very important to receive heat was great.This is ensured by a uniform distribution of heat.The lower the coolant in your radiator, the lower its inertia, and this affects the efficiency of the equipment.Modern radiators included in the mode for less than 10 minutes, which contributes to more rapid heating of the premises.

Radiators made of various materials, and this pig-iron, steel, bimetal aluminum.

choosing radiators for your home you need to pay attention to the following parameters:

  • operating pressure;
  • Rated heat flux - the higher it is, the more efficient the radiator;
  • size, weight;
  • cost.

Cast iron radiators have a high thermal conductivity, pressure-resistant, slightly susceptible to corrosion.This type of radiators is obsolete, more than 100 years this type of radiator heats the house, and a modern heating system it is no longer used.

Steel panel radiators , consisting of two stamped sheets are available in our country since 1960.From cast iron, they are mainly distinguished by the proportion is three times lighter, and thermal inertia, heat up more quickly, exactly as cool.These batteries are used mainly in low-rise buildings.

Aluminum , made of an alloy of aluminum and silicon.Aluminium - material that has high thermal conductivity, but it is not resistant to corrosion.In this very demanding these radiators to the chemical composition of water.They are used in individual heating systems.

Bimetallic resemble aluminum.The coolant is circulated through the steel pipes, which carry heat from extruded aluminum heat sink.They are also used as the aluminum, but they have a considerably longer service life.

convectors - enclosed in a special housing under which air enters and passes through the heat sink.In such systems, 90% of the heat transferred by convection.
