Rating of the best single-circuit gas boilers for 2022

In the autumn-winter period, great importance is given to the issue of heating. Speaking of residential buildings or buildings for administrative purposes, in which a water heating system with natural (forced) circulation is installed, one can resort to the installation of single-circuit gas boilers. The review was made up of boilers of various price categories, which, according to buyers, have good heat dissipation.

General idea of ​​the product - selection criteria

The product is a tank, inside of which a heat exchanger is placed. The coolant in it heats the water for hot water supply. There is also a valve that controls the flow of fluid from the boiler, which is also based on the principle of DHW priority. It is worth noting that almost all gas single-circuit boilers are equipped with devices for the operation of the boiler.

How to choose a product - classification of boilers

Based on the name of the product, the question arises: what other boilers are there?

There are 2 types of equipment - single-circuit and double-circuit. The first of them are intended for heating only rooms, others can also supply hot water.

Note! If a single-circuit model is connected to an indirect heating boiler, then it will also be able to supply you with hot water.

Types of boilers are considered according to the following parameters:

• Combustion chamber type (open/closed);
• Management (mechanical/electronic);
• Raw materials (liquefied gas, natural gas or a combination);
• Installation method (floor / wall).

In order not to make mistakes when choosing, you need to clearly understand what type of product you specifically need. Therefore, you need to focus your attention on such conditions as performance (power indicator), installation conditions (compare the diameters of the nozzles and chimney with the room in which the boiler is located), as well as special features.

Special features include a security system, the presence of additional devices (thermometer, pressure gauge, etc.), various controls and functions.

Selection Guide

To understand with which camera it is better to purchase a product (open, closed), you need to study the principle of operation of the equipment.Boilers with natural draft take combustion air from the room in which they are located, and the exhaust gases enter the chimney. Therefore, it is very important that the inside of the chimney be lined with a stainless steel insert to prevent collapse of the brickwork due to condensation.

Models with a closed combustion chamber are equipped with a special smoke exhaust system, so they do not require a chimney in the room. Combustion products are eliminated immediately from the furnace. Such devices are the best, but expensive.

As for the installation of equipment: the floor version will require space not only for the apparatus, but also for the piping (includes the installation of the pump, all its elbows, bushings, taps), as well as for the boiler, plus you need to add the installation distance according to the requirement. It is important that a vertical chimney be equipped. If you need a powerful unit, then the floor model is your option.

Wall models differ from their counterparts in compactness, as well as economy in terms of installation. The removal of combustion products can be done either through a vertical chimney or directly through the wall. The main disadvantage of this design is the low thermal power (up to 35 kW), the need for annual maintenance, while the floor boiler is enough to clean once every 3 years (sweep everything out of the furnace).

Despite all the nuances, the choice of a gas single-circuit boiler remains with the buyer.

Purchase and its nuances

The popularity of models among gas boilers is explained by reliability and practicality, at a time when the condensing apparatus, although modern and more economical, requires more electricity. Its efficiency can vary between 110-115%.Other disadvantages include its high cost, which is 2-3 times higher than for gas equipment and the formation of condensate during operation, which is highly oxidized and cannot simply be drained into an autonomous sewer.

The parapet boiler, although a chimney-free non-volatile device, is intended only for heating small rooms, houses. The main disadvantages of the product are the need for constant gas and its pressure, stringent installation requirements, constant monitoring of gas leakage, as well as the assistance of specialists during connection and maintenance.

What else to look for when purchasing a single-circuit gas boiler. By studying the product description, customer reviews, it is easy to track popular models. The best manufacturers always occupy a leading position in the market, which means that they can “boast” of the quality of the goods and the flawless operation of the boilers. In the online store, you can put a filter by price, by type, new items, and the like, which makes it easier for the consumer.

Take note of what product you need right away: from a domestic manufacturer or a foreign one; with mechanical control or electronic, budget options or more expensive.

The purchase can be made online - this is the fastest and most reliable way. To begin with, in the "Filters" section, you must specify all the requirements for the equipment, then select the appropriate model from the proposed list and add it to the basket. Next - placing an order (filling in the data and delivery address at a convenient time for you).

Conclusion: installation tips

How to choose the right model of the device is described in detail above, but finally, it is worth listening to advice if the consumer decides to install a gas boiler:

• The 1st start must only be carried out by a specialist;
• The equipment should be selected in such a way that in the future it would be easy to get to its service center;
• During a thunderstorm, the boiler must be turned off;
• In order for the equipment to work stably, it is necessary to purchase a voltage stabilizer for those models that suffer from power surges in operation.

Which one is better to buy a gas single-circuit boiler from the proposed list - the choice is yours. The rating consists only of high-quality models that justify their cost. But before installing the device at home, it is necessary to draw up an installation project and coordinate it with various regulatory authorities on this issue.

The buyer must understand that the installation must meet the mandatory conditions: the presence of a good ventilation system and the removal of combustion products, and these are additional costs.
