Parapet boiler what it is

There are many different systems and technologies available today for heating our homes. The phrase "parapet boiler" is one that’s becoming more and more popular in the home heating industry. However, what precisely is it? In essence, a parapet boiler is a kind of heating system that is placed outside of a building as opposed to inside.

This particular positioning has a few clear benefits. It saves important interior space because the boiler is mounted on the outer wall. This can be especially helpful for homeowners who want a more minimalistic interior design or who have limited space. Furthermore, since any potential problems are less likely to affect the interior of your home, having the boiler outside can lower the risk of water damage to your property in the event of a leak.

Now, you may be wondering how effective and efficient parapet boilers are in comparison to conventional heating systems. These boilers are made to be extremely efficient, and they frequently use cutting-edge technology to guarantee the best possible heating results. They can be especially useful for consistently delivering warmth, even in the year’s coldest months.

The simplicity of maintenance for parapet boilers is another important feature. Since they are installed outside, it is frequently possible to service and repair them without going inside the house. For homeowners, this can simplify and improve the convenience of routine maintenance tasks.

To sum up, a parapet boiler provides a contemporary and compact way to heat your house. Many homes wishing to upgrade their heating system find it to be an appealing option due to its external placement, efficiency, and ease of maintenance. You will learn more about the features and advantages of parapet boilers as we delve deeper into their details and consider whether they are a good fit for your house.

Advantages of gas heating systems

Among all the different kinds of heating equipment, one kind that needs to be mentioned is the parapet gas boiler.

A parapet gas boiler: what is it? This is a contemporary smoke-free unit that is typically used in private homes and apartments in multi-story buildings whose designs do not call for the presence of conventional chimneys. One of these gas parapet boilers’ primary design features is a closed combustion chamber for fuel waste. This benefit is particularly apparent in small buildings because they won’t "give" up their air to improve combustion and smoke extraction efficiency.

When compared to other models with similar functionality, parapet gas boilers offer numerous benefits.

  • Effective heating of the room along with low financial costs for installation and maintenance of the structure;
  • There is no need to equip your home with an additional structure for storing fuel resources;
  • The ability to customize the amount of fuel consumed;
  • there is no emission of dirt, dust and debris, as when heating the house with wood and coal;
  • ease of installation and maintenance;
  • fast heating of the coolant;
  • the possibility of adjusting the temperature regime.

The installation of gas parapet boilers requires a permit, which is provided by cadastral organizations. This is one of the drawbacks.

Coordination of the technical paperwork, authorization, installation, pressure testing, meter checking, and sealing typically takes six to twelve months. Although this is an extremely convoluted bureaucratic process, the system’s overall functionality and significant savings ultimately justify it.

What is the principle of smoke extraction?

Boilers that use parapet gas must be able to operate the combustion product outlet and air supply system with competence. There are two varieties of this kind of equipment: forced and natural draught.

The first option is distinguished by the waste from combustion leaving on its own via a unique chimney that goes through the home’s roof. In contrast, the second kind releases the combustion products through a network of coaxial pipes that exit through the wall overlap outside. Typically, a fan is employed in a forced-draught device to expel smoke outdoors. Additionally, one of the coaxial tubes "takes" the air for blowing directly from the street.

While air is drawn from the room where the gas parapet boiler is located in order to remove combustion products using a natural draught. These heaters go by the name openers as well.

Design of a solid fuel unit’s chimney

Models with a closed draft, or those that remove combustion products from the room without the use of air masses from the room, are the most desirable for residential buildings.

Boiler functionality

This equipment can be single or two-pipe, depending on the type of heater (mini gas wall-mounted boiler or standard floor standing boiler). The first version is only used to heat the space; the two-circuit version is used for both heating and hot water supply.

One notable benefit of these heating units is their ease of connection to the heating mains from any side. This simplifies the boiler installation process by allowing the apparatus to be placed in the most practical location.

A small device like this can be mounted anywhere that is practical.

Natural gas is the fuel that most perimeter boilers run on. However, they are also easily retrofittable. Thus, the heater can be made to run on liquefied gas instead of conventional gas by simply replacing the burner. This implies that in the event of an emergency or when there is no connection to the centralized gas mains, the heating system may be heated using gas from cylinders. These heat units can be installed even in homes without gas or electricity by retrofitting them with a gas-balloon installation, which gives them complete autonomy.

Advantages of heating parapet boilers

Such heating units have a lot of advantages. So, for example, if you read numerous reviews of parapet gas boilers, you can conclude that many people are satisfied with the compact size of the units. And even if you own a small apartment or house, then giving your preference to such heating units you will never in the future will not regret the choice made. Parapet heaters can easily fit under the kitchen table. And some craftsmen in order to increase the usable area of housing in general place heat units in niches under the window sills. Moreover, if there is a possibility to lead the gas pipe to another room, it allows you to install such equipment in any room of the house, regardless of its purpose.

Naturally, it is important to emphasize the use of the pipe coaxial system for the output of combustion products once more. People choose parapet gas boilers over other options because of this benefit.

The fact that radiators do not need to be installed in the space where the heater is located is another benefit of these heating systems. The unit’s casing is actually filled with numerous convection holes, which allow heat energy to be output into the space and warm it to a comfortable temperature for habitation.

When selecting a heating parapet boiler, be sure to consider the equipment’s power as this will determine whether or not it can fully heat your home.

It’s also important to remember that the majority of these devices’ models have sophisticated control units installed. The automatic system allows for the monitoring of the coolant’s condition in the system. This occurs based on the following principle: the heating unit automatically activates and heats the thermal circuit when the control unit’s maximum permitted temperature is reached.

Furthermore, parapet type heaters have unique components (pressure gauges) that allow the heat circuit’s pressure level to be tracked. Furthermore, even those who have never used this kind of technique before can handle this unit because the control system is a reasonably understandable program.

You have the option to express your preference for the heating unit that best suits your home’s needs based on the information provided. Our advice should assist you in making the best decision, which will be based on the effectiveness and caliber of your home heating.

What is a parapet gas boiler?

The majority of private residences and apartments without traditional chimneys are equipped with parapet boilers, which are energy-efficient, smokeless appliances. These parapet gas boilers are unique in that their closed combustion chamber, which is separated from the room housing the gas boiler, is their primary design characteristic. This benefit is especially beneficial in small spaces where there isn’t as much air extraction needed for optimal combustion.

The installation of a special horizontal coaxial chimney is necessary because the parapet gas boiler cannot function without the intake of air for combustion and the removal of combustion products. As a result, all operations are carried out with the assistance of the house’s outer wall. (See also: Which gas boiler is the most cost-effective?)

There are just two pipes in the chimney, and they are nested inside each other. Air enters the chamber with the assistance of an external tube, and as a result of the internal, combustion products are released. As you can see, everything is really simple and practical.

The fact that parapet gas boilers have a convection lining inside the hole is another benefit. Without adding a dedicated heating radiator, this addition aids in providing heating for the room housing the gas boiler.

Important features

Standard boiler construction involves a rectangular shape. This enables a more convenient and straightforward installation process. These boilers are also left- or right-handed. Boilers that have been manufactured in the left version have an automatic system on the left side of the apparatus, and spigots necessary for connecting to the hot water supply and heating systems are on the right side. The correct version of the gas boiler Helios is identical in every way, but it is viewed from a different angle. (See also: Boilers using gas)

Single-function and double-function gas boilers are produced for the parapet type of heating. The boiler body of a dual-function boiler houses a tubular flow water heater that is necessary to heat water for various household purposes. Due to its relatively high coefficient of thermal conductivity, copper is the primary metal used in the construction of these heaters.

One major benefit of Italian gas boiler parapet is that it can be installed anywhere because it doesn’t need to be connected to a chimney. Energy is not a requirement for perimeter boilers. Parapet boilers are frequently placed in the sill niche of a residential home. Additionally, they are employed in the forced natural circulation system of water heating systems to provide warmth to buildings.

Gas boiler Kerber, which has a steel heat exchanger

These boilers, which use a steel heat exchanger, can be installed in both private homes and apartments without the need for chimneys. The parapet boiler’s dimensions enable installation anywhere that is practical, such as beneath a window sill. It is possible to connect the heating system on the left, right, or both sides simultaneously. Furthermore, these kinds of boilers can run on liquefied gas in addition to regular gas. (See: Site Map, too.)

Let’s clarify the parapet boiler’s technical design:

– A coaxial baffle sealed with silicone to guarantee a tight connection to the heat exchanger;

– Turbulizers are installed in the pipes that allow the combustion products to be discharged; their unique design increases the efficiency of heat transfer from combustion products to heat carriers and helps to ensure a high level of efficiency;

– A window that allows for visual control over how the pilot and main burners burn;

– The hot water supply circuit is constructed as coils, or water heaters, using 12 millimeter-diameter copper tubes. Its purpose is to warm up the service water. Because copper is a superior heat conductor, the water heats up considerably faster, saving both time and energy. (See also: Gas boiler room thermostat)

Siberia and Renai boilers

Improved parapet boilers with sealed combustion chambers and universal heating system connections might be available from certain companies. Heat exchangers for heating boilers gas Siberia are rectangular in shape and consist of a single, three millimeter-thick steel case that has been welded together. Semi-automatic welding units are used to create welded seams, resulting in homogeneous sluices of superior quality. In the event that repairs are needed, each external joint is simple to reach. The combustion products travel via welded, solid-tensioned pipes inside the body. The housing is intended to function in a heating system with a 0.3 MPa operating pressure.

The safe and steady operation of the gas boiler Renai is evident during low pressure and fluctuations in the mains’ gas pressure. The entire combustion chamber is uniformly lit by cylindrical micro-flame gas burners, which contributes to the heat exchanger’s ability to heat water quickly and evenly.

The offered assortment

Regarding the model line, it consists of gas boilers with single circuit capacities of 7, 10, 12.5, and 15.5 kW, as well as water heating models. In homes and apartments without a chimney connection that have a total heating area of up to 140 square kilometers, parapet boilers can be utilized. (See also: Benefits and drawbacks of gas boilers that are mounted.)

Modern gas automatic systems with piezoelectric ignition and micro-flame burners are fitted in parapet gas boilers. Steel with a three millimeter thickness is used to make the heat exchangers in parapet boilers.

An entirely new heat exchanger design, which eliminates the need for left- and right-handed execution and greatly simplifies installation, is a distinguishing feature of the parapet boiler models. The connection is special because it eliminates the boiler connection sockets to the hot water supply and heating system on both sides of the appliance. This allows side doors to be left open, saving workspace in the space, and the parapet boilers blend in seamlessly with any kitchen’s interior design.

The enhancement of the device’s appearance is given particular consideration when developing new parapet boiler models. Convenient use and stylish, contemporary design are the primary requirements. The unique elegant appearance of the new parapet boilers helps set them apart from other Russian analogues. They will eventually have a working panel with visual control and regulation devices, which is very convenient during use.

A little bit about the construction

Air is supplied to perimeter gas boilers via a unique horizontal pipe called coaxial that goes through the home’s exterior wall. The chimney is used to release the combustion products. Two pipes are positioned inside one another in a coaxial chimney. The purpose of the outer one is to allow air to enter, and the inner one is to drain the gas.

Parapet gas boilers are separated into two types based on circuit configuration: single circuit and dual circuit models. The hot water supply system’s flow water heater is integrated into the casing of the two-circuit models. Copper is frequently used as a material for heat exchangers due to its high coefficient of thermal conductivity. There is a 92% variation in efficiency.

The qualities of domestic parapet boilers are marginally inferior to those of imported boilers. However, they can also be equipped with an electronic control system to adjust the output and manage the DHW system automatically. Moreover, electronic control boards can guard against pipe pressure drops, pump jams, and boiler overheating or freezing.

What are the features?

These devices stand out due to their closed design that keeps them separate from the combustion chambers in the room. As a result, the air they breathe does not get consumed for the purpose of burning gas. This is particularly valid for compact spaces. One more feature that makes these boilers ideal for living rooms, kitchens, and hallways is their near-silent operation.

One more benefit of this kind of equipment is that it has a convection aperture, which allows the room to be heated without the need for heating radiators. The small capacity of these units, which may have an impact on the maximum amount of space that is heated, is one of their drawbacks.

To sum up, I would like to point out that there are a lot of boiler models available, so careful selection is required. Yes, there will be a clear distinction between domestic and foreign-made boilers. Everything also depends on how many circuits there are, among other factors. We hope your decision turns out well!

Parapet gas boiler

By design, a parapet boiler combines the best features of gas convectors and gas boilers to create a heating installation. These kinds of heat generators are energy-efficient, small-space heaters that are lightweight and portable. They are utilized in systems where the coolant circulates naturally.

Principle of operation and device

The following structural components are part of the heating installation:

  • a gas burner consisting of a gas valve and a burner;
  • heat exchanger;
  • hermetically sealed combustion chamber;
  • steel casing, which acts as a convective heating device;
  • gas duct designed for combustion products discharge and air intake from outside.

The following scheme corresponds to the operating cycle:

  • The pilot burner is ignited by means of piezo ignition.
  • After that, gas is supplied to the main burner.
  • Hot exhaust gases pass through the heat exchanger and heat its walls.
  • The walls of the heat exchanger heat the coolant of the heating system.
  • In the room where the parapet heating boilers are located, there is no need to install a radiator, since the hot air passes through the slits in the decorative casing and heats the air in the room.
  • After heating the heat exchanger to the set temperature (maximum – up to +90 0 C), the temperature sensor signals the need to close the gas valve. Burning of the pilot burner does not stop.
  • When the heat exchanger cools down to a certain temperature with the help of a temperature sensor opens the gas valve and ignites the main burner.

Take note! This type of boiler uses no energy at all and maintains the desired temperature automatically.

The pilot burner will stop burning and the gas supply will be turned off with the assistance of the flame control electrode if the gas in the main line is lost.

To remove combustion products, a coaxial chimney with a "pipe-in-pipe" design is utilized. The inner pipe allows for the outside discharge of flue gases, while the outer pipe allows air to enter the combustion furnace.

Boilers with parapet walls can be wall-mounted or floor-standing. The following units—7 kW, 10 kW, 12.5 kW, and 16 kW—represent the model range.

Advice: The power is chosen based on the heated room’s area.

A parapet boiler is a heating system component that"s installed on the edge or parapet of a building"s roof. Unlike traditional boilers located inside a home or building, a parapet boiler is situated externally, often to save space or due to design constraints. It works by heating water, which is then circulated through the building to provide warmth. These boilers are especially popular in urban areas where indoor space is limited. One of the key advantages of a parapet boiler is its efficiency, as it can be easier to install and maintain compared to internal systems. Plus, being outside means fewer noise disturbances inside the house. However, proper insulation and protection from the elements are crucial to ensure its longevity and performance. If you"re considering this heating option, it"s essential to consult with professionals to determine if it"s the right fit for your home"s heating and insulation needs.

  • The heating unit can be located in a kitchen or in a non-residential room near an external wall. This wall from the inside must be covered with non-combustible material.

Advice: Keep curtains, furniture, and other combustible interior items 200–300 mm away from the boiler.

  • The distance from the heating unit body to the facade elements may be 0,3-2,5 m.
  • An effective ventilation system must be installed in the room.
  • Coaxial chimney is not allowed to lead out into entrances, closed loggias and balconies.

The parapet boiler installation process involves multiple stages:

  • A hole is punched for the installation of the coaxial chimney with orientation on the outer ring.
  • Install the first air pipe spigot.
  • Install a section of water pipe.
  • Fix the fasteners and install the heating device.
  • Install the second spigot.
  • Chimney sections should be installed at an angle.
  • Connect the sections to the spigot.
  • Install the protection, connect the water supply pipes and install the expansion tank.

In essence, a parapet boiler is a kind of heating system in which the boiler unit is positioned high up or on the roof.
