Choosing a method of heating a house or apartment is one of the most important investments in your life. Condensing boilers meet all safety requirements, are suitable for floor and radiator heating, they can be multifunctional - they serve only to heat water or perform a double function. They have a number of other benefits, with an emphasis on those that help save money and energy. If you decide to purchase condensing gas boilers, the pros and cons of this equipment should be known in advance. Consider their main characteristics in more detail.
This is due to the design of this type of heating equipment. In contrast to the non-condensing, the operation of the condensing boiler makes it possible to maximize the use of combustible fuel. It also uses the energy that is usually lost during cooling of the exhaust gases as a result of condensation of water vapor.This gives an additional 11% to the heat received! After deducting the heat that is lost, we get about 107% of the heat.
We can safely assume that opting for a condensing boiler saves fuel. Although the cost of the condensing boiler is higher than the traditional, but after 4 years of normal operation, the purchase price will return. In order for this to happen, it is important that the heating system is reliable, good fuel is available (the gas must not have pollution), adequate, not too hard water.
It would seem that if you buy a device, it should give a 100% return every time it starts. Nevertheless, the condensing boiler is smart - it adapts its work to the external conditions, that is, to the temperature outside the window and, therefore, it “knows” how much you need to heat the house. It can be programmed, while it is possible to specify the heating temperature (that is, the lowest temperature that we expect during the cold period). And only then it will heat up to full capacity, and on the other days of the year it will dispense the heat adequately to your needs.Anyway, you don't even have to customize it! It adapts to the working conditions.
The condensing gas boiler is “smart” and therefore very economical. Only for a few days a year it will operate at full capacity, while on other days the device consumes significantly less fuel - you will save a lot of money on gas. In addition, the condensing boiler is much more efficient than the traditional one. It works much more efficiently and better when the temperature outside the window is above the calculated temperature. Paradox? But the one that pays off!
Most condensing boilers are closed. And the fact that they are closed automatically guarantees at least two big advantages - convenience and safety of operation.
Is it not absurd that the device used to heat the room for this purpose is forced to pull air from the street into the room, thereby cooling the room in which it is located? According to this principle, only boilers with an open combustion chamber, that is, traditional ones, work. They must constantly receive the air necessary for the combustion of gas, and this air comes in from the street and passes through your dwelling. Coppers closed much better solve this problem.They are convenient, since the ventilation system of the combustion chamber is carried out using an installed fan. With its help, the outside air enters the boiler not from the room in which the boiler is installed, but directly from the street. As a result, the room does not cool down due to the continuous circulation of air and warms up much better, especially in winter.
The fact that the boiler is closed also makes it safe. The additional case separates from vapors and protects against carbon monoxide poisoning. The very type of tightly “armored” boiler allows you to feel more confident and comfortable with it. In addition, the flow of air in this type of boiler is more efficient, since it is automated and the work of the exhaust sensor will not interfere with any, even accidental, intervention of an unwary family member.
Gas condensation wall boilers with a closed chamber require less space than models with an open combustion chamber. Thus, the boiler can be installed even in a small room. Condensation boilers are certainly much smaller than wood or coal kilns.You can buy condensing wall-mounted boilers or floor standing, so it is very easy to adapt them to different interior designs and your needs. They can be installed not only in the boiler room or bathroom, but also in almost every room. You can freely install it even in the hallway or in the kitchen. The condensing boiler works so quietly that you forget about its existence. Even more than that, it can be hidden in a niche or cabinet ordered specifically for this purpose.
A significant disadvantage of a condensing boiler is its higher price; however, given the savings in energy consumption, it must quickly pay for itself.
