How is the flue gas outflow from the boiler better?Side or vertical?

The combustion line has two very important functions

The combustion duct performs two very important functions - this is a wired structure for removing combustion products from heating devices to the atmosphere, which is also responsible for the production of the room in which the heating appliance hearth is placed, appropriate vacuum, thanks to which it is possible to suck effectively through holesventilation air necessary for combustion.This second function is performed only in chimneys, which operate on the basis of a natural chimney draft.

The chimneys consist of several parts: a chimney, a flue, an internal combustion system, an exhaust outlet and an exhaust inlet, as well as a chimney flue.The type of combustion system is strictly dependent on the type of heating device chosen by the investor.Manufacturers provide requirements that such an installation must meet to ensure effective heating and safety.

Only after thorough familiarization with the technical specification of the device can you start designing an internal combustion system and choosing the right types of cables.In today's post we will focus on two types of exhaust gas discharge: a vertical cable and lateral throw.We will describe their specificity and explain when to take into account these solutions.

What characterizes the vertical cable and what is the use of?

Most buildings are used vertical cables.The regulations specify the direction of conducting such wires in building facilities and should be vertical.Light deviations from the vertical on a section not longer than 2 m are allowed.The internal combustion ducts must be made of non -flammable materials and should be placed a chimney buzz located in the wall of the building.The type of vertical cable used must always be in line with the type of heating device and have a minimum height to be able to effectively fulfill its function (minimum 4 m for gas fired boilers, and 5 m for boilers fired with fuel oil).

What characterizes lateral edition and when can it be used?

Side east is a solution that allows flue gas discharge through the building wall.However, it cannot be installed in every building.It is allowed to use them only for heating boilers with strictly defined nominal power (it cannot exceed 21 kW in the case of free -standing buildings and 5 kW in other residential buildings), and its location on the wall cannot be accidental - it must be preserved - it must be preserved -Specified distance from windows, doors, hoods, etc.., as well as the appropriate height above the Earth (not higher than 2.5 m above the ground level).

Side east should be used as an alternative to vertical flue gas discharge from the boiler.Its assumption is recommended when it is not possible to use a traditional vertical cable.This solution is recommended for buildings where the heating system is modernized and problems with exhaust gas discharge by the existing chimney appear.

Side east also works in situations where the investor intends to add a second boiler to his heating installation (e.g..Hanging gas boiler) to ensure better thermal parameters.In such cases, it happens that in existing chimney shafts there is no place needed to place an additional exhaust gas discharge from a new device, so lateral discharge is the only possible option.
