Exhaust pipes what should be the necessary element of

Ventilation in a house or apartment is necessary to remove burning waste, odors and steam. Even if your home is provided with central heating and hot water, you can’t do without a hood in the kitchen and bathroom. Especially obligatory exhaust pipes for ventilation, where the boiler, furnace or gas equipment.

Types of chimney and ventilation pipes

1. Multi-Shell Prefabricated Analogs. They are a body of concrete of light varieties, covered inside with glazed fireclay. Thermal insulation is mineral wool. Such a chimney for a gas boiler, a furnace is lightweight and easy to install.
2. Factory made. Their design is similar to multi-shell. Standard quality elements simplify installation and repair.
3. Analogs with exhaust ventilation channel for removal of combustion products. This type is well suited for autonomous heating installations. The exhaust pipe for the boiler, in addition to the removal of waste substances, simultaneously delivers the necessary air for the combustion process.

1. Moisture resistant pipes. They are optimal for low-temperature heat generators and condensing boilers.

Note! When the temperature of waste substances below 100? condensation forms, settling on the surface. The air entering the basement section of the pipe collects and removes moisture to the outside through a special opening.

1. Free-standing chimneys. This variant is applicable for large central heating systems. Consists of one or more internal gas outlet pipes, an insulating layer and an outer casing. The shell is made of steel, brick or reinforced concrete.

Hood for gas boilers

What should be an individual exhaust pipe for a gas column, depends largely on many factors. Location, power and type of boiler is important. Also important is what the equipment works on (also learn how to make a greenhouse from plastic pipes).

So, the exhaust pipe in a private house for a coal boiler is different from a pipe for a gas boiler. Cylindrical stainless steel pipes are the most popular among homeowners.

Sizes of chimneys

It is clear that the hood must cope with its task and not bring trouble to the owner. What should be the exhaust pipe for ventilation in a private house to meet all modern requirements?

What should be the height

1. Depending on the volume of produced gases, the height of the pipe directly depends. If you have purchased an individual low-power installation, an instruction must be attached to it. Including recommendations for supplements, and pipes in the first place.
2. Experts advise not to make the level of height less than 4 meters. In the case of using gas as fuel, the pipe is set at 4.5 meters.
3. The minimum height of the exhaust pipe above the roof is 40 cm.

Note! In the case of increased thermal capacity of the heating installation, as well as in the presence of several boilers, it is necessary to take appropriate measures. Each of the heat generators must be supplied with a separate pipe.

About diameter

1. The diameters of both the pipe and the holes for it do not make more than the same parameter of the chimney.
2. Pipe for geysers and furnaces must be equipped with a hatch. It is necessary for the removal of accumulated soot.
3. Do not make more than three turns tap. Also under the entrance to the pipe there is a space where soot will accumulate. This is important for cleaning, and for the proper accumulation and removal of condensate to the outside.

Roofing ventilation ducts

It is difficult to imagine a private house without a pipe on the roof. Without it, it will not be possible to create the microclimate necessary for a full stay.

If no one lives above you, it is advisable to divert the burning waste through the roof.

1. The ventilation system must be supplied with a protective cap. This will prevent the ingress of precipitation inside. Displays the channel of kitchen hoods, as well as systems with a channel heat exchanger and a fan.
2. Pipes not only remove all unnecessary, but also reliably protect the ventilation equipment from moisture and dirt.
3. Careful attention to installation and compliance with all rules will contribute to the proper operation of all equipment, as well as ensure the safety of homeowners.

Note! The chimney must have a margin of safety. By standards, the pipe must withstand a 10-point wind (up to 30 m / s). With storm winds, even for every m 2 of walls there is a load of 50–60 kg.

A thin and loosely fixed product will simply break.

PVC Products

The usual galvanized add-ons are gradually being replaced with more modern and technological counterparts.

Polyvinyl chloride is distinguished not only by an acceptable price compared to metal, but also by practicality.

1. PVC pipes are not subject to corrosion, they are not at all afraid of high humidity.
2. A distinctive feature is the increased strength, respectively, and service life.
3. At the very least, compared with metal counterparts weight, accessories are able to withstand significant loads.
4. For those who intend to do the installation with their own hands, it will be extremely easy to handle plastic taps.
5. Features of production are such that the finished product has no seam and roughness. Perfectly smooth surface prevents static resistance to the passage of air.
6. If a plastic duct is treated with an antistatic composition, it will not attract particles of dust. This will save the owner from frequent cleaning and extend the life of the equipment.

Installation Features

1. Before installation, calculate the optimal output location. The pipe is installed relative to the downwind slope, to reduce wind load.
2. If condensate drips from the exhaust pipe, it means that the length of the sinus for snow accumulation is too large.
3. For a certain type of equipment, an appropriate elimination is selected.

Conclusion

Only a properly selected and installed pipe will improve the performance of the entire system and eliminate unscheduled repairs and adjustments (find out here how to warm up the pipe).
