When a house is built, and it's time to do conduct communications, one of the most difficult issues is the choice of the boiler.As a rule, as the main element in favor of heated water heating system.And all kinds of oil radiators, electric underfloor heating systems, infrared heaters, wood and electric fireplaces are used for additional heating.The first step is to decide what kind of fuel you prefer, and then select the model of the unit.It should be noted that in recent years the most popular gas boilers - private home is the best option.


main fuels ↑

Depending on the type of energy orcombustible material is separ

ated gas, electric, solid and liquid fuel boilers.Many manufacturers also offer a fairly wide range of so-called combined boilers to switch from one fuel to another.So in areas where there is no central gas supply and electricity shortages often occur very convenient to use boilers that can run on both electricity and solid fuel (coal, wood, briquettes).

Floor gas boiler - the most demanded type of equipment justified the popularity of his power, the ability to serve two circuits

makes the final choice is based on convenience and cost of operation of the heating equipment.The most economical is it gas boilers, and too much trouble, they do not deliver.Modern heaters are equipped with automatic control system, which ensures trouble-free operation with virtually no human intervention .

the undeniable benefits include gas central heating and there is no need to stockpile fuel and high efficiency (up to 95%), and relative safety.Furthermore, gas boiler often does not need a separate space - a boiler.And with enough attractive design unit to easily fit into the interior of your kitchen.

types of gas equipment ↑

In order to choose the right gas boiler for a private home, you must first understand how they differ from one another.

Separation of on-site ↑

There are floor and wall units.Wall boilers are usually equipped with a copper coil, which causes their light weight.It is because of the rapid burning of the copper heat exchanger for large loads such boilers have a power limit of 35 kW.Outdoor boilers are equipped with cast iron heat exchanger and are indispensable for heating large areas.

differences on the basis of the work ↑

Volatile boilers

This equipment is equipped with not only the burner and heat exchanger, and a circulation pump, which pumps a constant pressure in the system.When properly installed, this boiler ensures that the coolant will reach all corners of the heating system, maintaining the set temperature.In addition, the installation of pipelines for this boiler is much easier, since there is no need to comply with a constant slope.Choosing a gas boiler for the house, remember that during a power outage, volatile equipment is not working.So if in your area such troubles are not uncommon, reserved by diesel or petrol generator.

volatile boilers

This is quite an outdated view of the gas equipment, which requires a larger diameter in-house pipeline compliance bias and installation of open expansion tank.However, when combined with a circulating pump and a few in-house to improve the system, the installation of gas boilers of this type may be the best option for areas where it is often cut off electricity supply.

Setting pump gravity systems Heating ↑

Make it easy enough.

Installing the circulation pump
circulation pump is inserted into the gravity heating circuit if the system can not cope with the work and the temperature set at different points radiators differs significantly
  • In return, 20-30cm in front of the entrance to the boiler, it is necessary to build a bypass onand wherein the pump is installed.
  • pump must be installed before the filter cleaning rigid that prevent getting into the pump mechanism of solid particles and thus will protect it from damage.
  • On the return line between the inlet stroke and its output is set valve.
  • pump is connected to the mains.When the pump is in operation, the valve on the main tube must be closed.If the power is switched off, it is enough to open the valve and gravity circulation resumes.

Important!This method of switching is possible only on the pipeline, which was originally prepared for the installation of non-volatile boiler.That is when all the slopes and diameters of the pipes.The system, designed for the installation of the pump, self circulation of coolant is impossible.

Progressive condensing boilers ↑

This is a new generation of heating equipment.In order to understand what is the main difference, you need to understand a little principles of the conventional gas boiler.The fact that, together with the combustion products through the flue displayed significant part of the steam, resulting in a loss of thermal energy.Manufacturers go for it completely consciously to prevent condensation inside the boiler that could quickly lead to corrosion of the boiler and damage it.

Internal structure of condensing boiler

Condensing gas boilers for the home designed in such a way that the steam is cooled in a heat exchanger to a temperature at which condensation occurs.This occurs due to the interaction of steam and water from the return line.When this heated coolant itself and hence heat losses are reduced.

most advantageous to install such equipment in homes where the water is arranged a "warm floor", then there is no radiator and heating is provided by a long pipeline laid under the floor.

Separation of gas boilers in the category ↑

classification intended ↑

most often when there is a question of choice, installing a gas boiler which type of expedient - single-circuit or two-circuit.Single-circuit boiler is designed only for heating, but also a double-heat water for hot water supply.The answer to this question is quite simple: it all depends on the boiler output.If you are planning a large enough home heating, and thus set a powerful boiler, it is better to establish a separate single-circuit heating system and boiler.For the home area of ​​200m2 and you can use two-circuit system.

By type of heat exchanger ↑

to bypass the boiler is very important to choose the right type of heat exchanger.On this depends the life of the unit.There bithermic heat exchangers operating on a "pipe in pipe", and devices with separate heat exchangers.In such boilers used for heating a copper coolant heat exchanger and the hot water supply - stainless steel.Bithermic boilers are only suitable for heating water received from the central water supply system.If you use water from a private well or a well - install the boiler with two heat exchangers.

By way of flue gases ↑

Another important characteristic of the gas boiler is a method of exhaust gas.There are turbo (nedymohodnye) and device chimney.

Installation of gas boiler chimney systems flue gases, as the name implies, requires a chimney with a natural draft.In addition, such units in an open combustion chamber is maintained by a fence of oxygen from the room where it is installed.Enterprises gas industry imposes very strict requirements to the installation of boilers.As a rule, it has to be specially equipped boiler.

Turbocharged boilers are equipped with a closed combustion chamber, to which oxygen is forced from the street by a special tube.And the products of combustion are discharged by the fan.Most of these devices are equipped with a coaxial tube - internal contour is given by carbon monoxide, and external air is supplied for combustion.

Automation and safety ↑

Virtually all modern heating systems are equipped with an automatic safety system, which blocks the boiler if there is any problem.This system stops the gas supply if the burner goes out, that will save you from poisoning.Most security systems react as there is no smoke, overheating, water, power failure and overheating of the coolant.

Automation for boiler

When choosing a boiler note, whether the automatic unlocking system for solutions.If after the safety system has been activated, the boiler will be enabled manually, it is not suitable for people who are often absent at home.Depending how long the heating in the winter there is a danger to "unfreeze" the heating system, which will lead to the rupture of pipes and will entail the need for replacement.

Installation and maintenance of gas boilers ↑

Remember that the installation and maintenance of gas equipment should be done by the gas company.Do not try to do it yourself.This may cause not only serious penalties, but also a danger to life and health of your loved ones.Any work on the gas pipeline and gas equipment must only be carried out by specially trained people.
