What is a parapet gas boiler?

Colonial gas boilers are heating systems that combine elements of turbocharged and atmospheric models. They have a closed combustion chamber but are otherwise entirely energy independent.

The use of a coaxial chimney, which is connected to the back of the unit and empties into the street, is a unique feature of this design. Convection processes are responsible for both the intake of fresh air and the removal of smoke.

There are no smells in the room when the boiler is running, and there aren’t even any remnants of soot or other combustion products.

Furthermore, oxygen in the space does not exhaust, enabling you to preserve a typical microclimate.

The capacity of parapet boilers to function as standalone heating components is another feature. Hot air escapes through unique holes in the lower section of the case.

It maintains the appropriate temperature in the space by moving around it.

What is the difference from the usual?

The ability to obtain increased safety from the energy-dependent structure and the absence of influences on the interior atmosphere of residential premises are the main differences between parapet models and ordinary boilers.

When a traditional atmospheric boiler uses surrounding air to burn oxygen actively and necessitates continuous ventilation, parapet models function independently and do not interfere with the air exchange system.

An additional distinction is that the parapet boiler functions similarly to a stove because it can heat the air on its own.

Advantages and disadvantages

The following are some benefits of parapet boilers:

• no electricity consumption;
• no internal air is used, there is no additional load on the ventilation system;
• there is no need to connect to a common chimney;
• low fuel consumption;
• efficiency, practicality, resistance to external loads.

The models’ drawbacks can be taken into account:

• installation requires making a hole in the wall from 25 to 31 cm in diameter;
• installation is only possible near an external wall;
• it is not possible to provide full-function control and protection of units and parts of the unit (for non-volatile models).

Even with the current drawbacks, users give parapet boilers excellent ratings. They are in ever-increasing demand.

Device

The parapet unit’s design is nearly identical to that of every non-volatile boiler.

After reaching a high temperature in the primary heat exchanger, the coolant enters a three-way valve, also known as the mixing unit. It involves mixing colder "return" with hot liquid to raise the heating agent’s temperature to the levels dictated by the mode.

In double-circuit models, the coolant goes through a secondary heat exchanger that prepares hot water before it enters the three-way valve.

The structure of the chimney and combustion chamber, which are unusual for these kinds of devices, is where the differences lie. A coaxial double pipe is used to remove smoke; the inner cavity serves as a chimney, and the outer cavity allows fresh air to enter.

The combustion process is ensured by drawing air into the closed combustion chamber. It expands upon heating, pushing aside smoke and other fuel-burning gases. Certain models have two independent pipes, one for air supply and the other for smoke exhaust.

By selecting this option, you can improve convection and stabilize the gas movement processes.

Kinds

Parapet boilers come in a variety of design options that are categorized based on particular attributes.

By way of installation:

• wall-mounted. Installed in a hinged manner on an external (load-bearing) wall. According to installation conditions, weight and power are limited;
• floor. Installed on the floor. If it is wooden, a non-flammable stand is required. There are no restrictions on weight, dimensions and power.

Using a power supply:

• volatile. The design contains components that require the use of electricity – a circulation pump. electronic control board, etc.
• non-volatile. Work only on mechanical control. A good choice for remote villages and areas with power outages.

By group of operations:

• single-circuit. Able only to provide heating of the coolant;
• dual-circuit. In parallel with heating the heating element, they are capable of preparing hot water for household needs.

The most efficient floor models are single-circuit ones, which are preferred by most users.

Our list of the top 5 parapet gas boilers for heating includes models that balance user satisfaction, dependability, and efficiency. Homeowners are given clear insights into their heating options by evaluating each boiler based on customer reviews and technical specifications. In order to keep your home warm and cozy during the winter, this article will guide you through the best options, regardless of your preferences for energy efficiency, compact design, or sophisticated features.

Operating principle

There are not many differences between the typical operation of gas convection units and that of a parapet boiler.

The coolant, which is heated by the burner and partially used to heat water, is then released into the heating circuit via a three-way valve.

This hasn’t changed at all. One unique characteristic is the boiler’s capacity to act as a convector, allowing the room where the unit is located to be without radiators.

Furthermore, a unique technique for smoke exhaust and air supply is employed. Excess air pressure in the upper portion of the combustion chamber is created when the burner is lit, and this causes the air to be expelled outside with the smoke.

Simultaneously, a vacuum forms in the lower section, forcing fresh flow through the coaxial pipe’s outer section. There appears to be a pressure differential akin to that found in traditional ovens.

This eliminates the need for a turbo fan when using a closed combustion chamber.

The air intake pipe and chimney may be constructed independently in some designs, but this does not alter the basic working principle.

Rating of TOP 5 parapet gas boilers

Parapet boilers are becoming more and more popular because they lack many of the drawbacks of wall-mounted models.

Let’s examine the most well-liked models:

Lemax Patriot-12.5

Domestically produced floor-standing parapet boiler that is not volatile. The unit has 12.5 kW of power. This works well for spaces up to 125 square meters.
