The growing area of \u200b\u200bmodern country houses require significant energy consumption. In addition, more and more additional sources of heat are used underfloor heating, heated steps of the porch, and so on. All of this expends more and more resources. And the tariff growth over the past ten to fifteen years, according to some estimates, has changed by an order of magnitude. For some this is not upset, but most owners of suburban real estate tend to save. There are not so many ways to save additional warming of rooms and the use of more modern technology, which allows to increase the possibilities of country heating systems. It is imperative that you familiarize yourself with such a technique in more detail to make sure significant fuel economy is possible. And it’s not so expensive.

Private house heating system

Natural gas is increasingly supplanting solid and liquid fuels that were familiar and common. In addition, in recent years there has been a sharp jump in the development of gas infrastructure in suburban areas. Therefore, gas is becoming the most optimal resource that can be used for heating private houses in cottage and summer cottages. Manufacturers of heating systems are offering more and more equipment that runs on these environmentally friendly and relatively inexpensive raw materials. The standard heating system of a private house is simplified to the limit and eliminates complex appliances and requires minimal maintenance.

The manufacturers and users come to the forefront of the device system, which allows to save even more on fuel. And here, the real breakthrough was the use of not an ordinary boiler, but an improved one, with additional functions to increase productivity.

Condensing boiler

Condensing heating boiler is able to select the latent heat of condensation of water vapor, which is contained in any type of fuel and when burning in ordinary boilers simply fly into the pipe. In addition, when the condensation effect is activated during combustion, the emission of harmful oxides is reduced, because, as you know, oxide is a chemical compound with oxygen, and if more oxygen is burned, then less of its molecules react with other elements. Two important factors of efficiency and environmental friendliness have long made condensing boilers popular in Europe, now their demand is palpable in Russia.

The most popular gas condensing boilers, but their use, obviously, depends on whether the blue fuel is brought to the site. There are various models of condensing boilers, both expensive and budget options are presented on the market. It all depends on the load on the heating system and the solvency of the buyer, and you can buy a condensation boiler in any hardware store offering plumbing products.

Before buying, you need to consult with specialists, as well as get acquainted with reviews about condensing boilers, since there are enough of them on the Internet.

The principle of operation of a condensing gas boiler

The classic way of heating water in traditional hot water boilers, where the heating process occurs due to the transfer of heat from burning fuel (wood, coal, diesel fuel, gas) in condensation boilers, is supplemented by the ability to use part of the heat that is carried out through the chimney. For this, an additional heat exchanger is built into the boiler. Such a pattern during the combustion process, the hydrocarbon oxidation product immediately turns into vapor and evaporates. If this steam is condensed, then upon cooling it will provide additional energy directed to heating the coolant.

Thus, over the same period of time, more water is heated, and less fuel is needed for this. This is where the savings are hidden. Measurements showed that the emission of harmful gases is significantly reduced when using the condensation effect. For example, CO (carbon dioxide) enters the atmosphere up to 90% less than with conventional boilers.

Condensing boiler installation

Installation of a heating system using a condensing boiler is similar to the process of installing a conventional hot water boiler. It is important to take into account the safety requirements for the entire system, and it is advisable to install the boiler on a ramp (with the floor version), wall-mounted boilers are hung in places where the least amount of dust is accumulated.

The condensation boiler is most effective when working in low-temperature systems, as ideal conditions for condensation are created if the return temperature is below the dew point, i.e. 40-50 degrees Celsius. Therefore, their use is very desirable with systems of underfloor heating or heating the steps of the porch.

Condensing boiler maintenance

Sophisticated equipment, which includes a hot water boiler, including a condensing boiler, must undergo regular preventative maintenance. It is not always possible and dangerous to independently carry out this procedure, and therefore it is better to entrust this task to a specialized organization. And personally, you can keep the boiler clean, and not only the boiler, but the whole system. Regular cleaning of dust and dirt will prevent it from entering the work departments and increase the life of the device.

Ways to increase boiler efficiency

From a school course in physics, we learned that efficiency (efficiency) tends to 100% and excess is impossible. However, this is not quite true. If additional mechanisms are included in the system, then its efficiency will increase above 100%. This is confirmed by the example of the use of condensing boilers.

If the thermal power of a classic boiler is approaching maximum (and this is not such a difficult task with the development of new technologies), then with the additional use of condensed water heated by the latent heat of the fuel and then cooling the energy transferring to the coolant, you can get up to 10% more power . Thus, under ideal conditions, the efficiency of the heating system will be 110%. It must be remembered that this is only the efficiency of the boiler, and not the entire heating system, so here we are talking only about the condensation boiler. The whole system increases efficiency when using, as we have said, a low-temperature circuit.
