Gas parapet boilers: a review of models
- one of the most convenient and common types of fuel for autonomous heating systems that are installed in homes. If we compare it with coal, then the consumer will not have to worry about replenishing stocks; it will only be necessary to connect the equipment to the local gas pipeline. Therefore, the largest number of heating systems is designed to use gas.
As one of the best options for such devices appears parapet boiler. Such units were originally developed as an alternative to the wall. The latter, although they had many advantages, were demanding in terms of operating conditions. In order to work properly, they needed a certain pressure, suitable water, good fuel and uninterrupted power supply. Non-compliance with these requirements led to the fact that they often broke down and needed maintenance.
Over time, they were replaced by parapet boilers, which are not so tough with regard to operational requirements, they are able to ensure the normal operation of the entire heating system.In general, such equipment is a non-volatile heating installation for private houses and apartments. The units combine the positive qualities of convectors and gas boilers. In order to make the right choice, you need to familiarize yourself with some of the offers of the market.
Overview of models: boilers from the manufacturer "Danko"
These devices are presented for sale in a wide range. Among them, the models “Danko 7-U” and “Danko 10-U” should be highlighted, which are made in the form of single-circuit devices with the additional option of water heating. It is possible to use such units for heating industrial premises and residential buildings, the area of which does not exceed 140 m.2.
Parapet boilers "Danko" have several options for power and steel heat exchangers. Side doors are missing in the designs, which saves space. The heat exchanger allows you to abandon the left-and right-hand execution. As practice shows, a double-circuit boiler of the “Danko 12.5” brand is notable for its usability, because the design is equipped with a panel that allows you to visually monitor and regulate the operation of the device.
Another parapet boiler - KSG-7 - has stainless steel micro-torch burners. The device is intended for private houses and apartments, to which there is no possibility to bring a vertical chimney. The cost of such a unit is 15 700 rubles. If you need a smokeless boiler, then you can choose a double-circuit version of 12.5UV from the manufacturer “Danko”, which costs 17 900 rubles. The unit is used not only for houses and apartments, but also for industrial premises, where it is not possible to bring a conventional chimney. Heated area can reach 120 m2. The steel heat exchanger is made of stainless steel, the design has a piezoelectric ignition and a micro-torch.
Overview of parapet boilers "Lemax"
Parapet gas boilers "Lemax" have a closed combustion chamber and are designed for heating small rooms. The output of products of combustion and air intake for work are carried out from the street through a coaxial hole, which is made in the outer wall. The combustion chamber is hermetically closed and fenced off from the room, which reduces the requirements for ventilation and prevents the penetration of carbon monoxide into the inside.
Such parapet boilers when installing require compliance with two rules. One of them is the presence of non-combustible materials at the base of the wall to which the equipment will be adjacent. In addition, a coaxial hole must go out into the open air. Coaxial chimney can not go on the closed loggias and balconies, as well as in the entrances.
The main features of Lemax boilers are the following features:
- protection of the room from carbon monoxide;
- the ability to work without organizing a chimney;
- compact size;
- easy installation;
- high efficiency due to the hermetic steel combustion chamber.
