Vaillant gas wall boiler

Rating of the TOP 15 best gas boilers Vaillant

In this rating, we have collected for you the best Vaillant gas boilers of different types, so that you can choose the one that suits you best.

How to choose a Vaillant wall-mounted gas boiler

When selecting a suitable heater, pay attention to several thermal characteristics and parameters:

• Features of the heated building - technical conditions in apartment buildings will not allow installing a boiler with an atmospheric combustion chamber. For an apartment, models from the turboTEC series are optimal.

Functional purpose:

1. The wall-mounted gas single-circuit boiler Vailant is installed in rooms where there is no need to heat hot water, or it is planned to additionally connect an indirect heating boiler. Heaters with one heat exchanger are characterized by high performance, therefore, they are used for heating large buildings.

The Vaillant wall-mounted gas double-circuit boiler satisfies the room's need for heat and the residents' need for hot water supply. The heat generator heats the water using a flow method. In the summer, the boiler operates on the principle of a conventional gas water heater.

Modification - the main difference between the PLUS and PRO series lies in the installed equipment and the degree of automation:

1. PRO models are equipped with the equipment necessary for work, without any special “frills”.

The PLUS series provides maximum operating comfort and is equipped with weather-sensitive automation and other useful devices.

After determining the basic operating parameters, the device is selected according to power and price range.

How to calculate what power a boiler needs

The easiest way is to calculate a wall-mounted single-circuit gas boiler Vaillant. For this, the formula is used: 1 kW = 10 m² + 10% reserve capacity in case of severe cold. Calculations will help you find the approximate power value, given the average thermal insulation of the building and a ceiling height of no higher than 2.7 m.

If the heated area is 100 m², an 11 kW boiler will be required. In the model range there is no standard power size that exactly corresponds to the result obtained. Therefore, a boiler is selected with productivity rounded up. For indoor use, turboTEC plus VU / 5-5 at 12 kW or an analogue with an atmospheric combustion chamber is optimal.

Determining the required power of a boiler with two heat exchangers is a little more difficult. When calculating, the thermal energy costs for heating the hot water supply are taken into account. Typically, another 15-30% is added, depending on the actual needs of residents for hot water.

For a room of 100 m², you need a wall-mounted double-circuit gas boiler Vailant, with a capacity of 10 kW + 10% power reserve + 20% average DHW value. In total, it turns out that 13 kW will be enough. We round the power up. You will need to purchase a 15 kW boiler.

Price range for mounted boilers

Prices for wall-mounted gas heating boilers Vailant are standard for equipment of this class produced by a European manufacturer. You can buy the boiler you like starting from 45 thousand rubles. and higher.

Several factors influence the price:

1. Burner type.

The principle of removal of combustion products.

Degree of automation and equipment configuration.

Power.

If we take into account that heating costs after installing Vailant boilers will decrease by 25-40%, the full payback of the equipment will be achieved after 2-3 heating seasons.

What to look for when choosing?

To choose the right gas boiler, you need to pay attention to the following:

• Heat exchanger material and design . There are heat exchangers made of cast iron, stainless steel and copper. The most durable is the cast iron option. But it is heavy and can burst if not used correctly. Therefore, a copper heat exchanger with a bithermal coil is considered good.
• Type of instalation . Boilers can be floor-mounted or wall-mounted. Mounted ones are inferior to second models in terms of power. But the choice still depends on the preferences of the buyer.
• Number of circuits . The manufacturer produces single-circuit and double-circuit gas boilers. The first type acts as independent equipment, designed to connect heating. Double-circuit models are capable of heating water for domestic needs and heating; they are used in private homes.
• View of the combustion chamber . There are two types - open and closed. A boiler with an open chamber is suitable for installation outside residential premises: in a basement or a special extension. With a closed one - in apartments where it is not possible to install a chimney.

By number of circuits:

• Single-circuit (VU). The boiler is equipped with one heat exchanger and serves only for heating the area. To organize hot water in the house, it requires connecting an additional boiler.
• Dual-circuit (VUW). Ensures the operation of the heating system and the supply of hot water.

By type of combustion products removal:

• Atmospheric type (Atmo TEC). The boiler is equipped with an open combustion chamber. Installed in a separate room. Does not depend on the electrical network.
• Turbocharged type (Turbo TEC). It is a wall-mounted device with a closed chamber. Requires connection to the electrical network. Equipped with a fan for adjusting thermal power, special fasteners for wall mounting.

How to choose the power of a gas boiler

You can make the calculation using an online calculator program . It will be necessary to enter data on the area of ​​the room, the thickness of the walls, the number of doors and windows, take into account thermal insulation and other information.

The program is free and allows you to select a boiler with minimal error.

To independently calculate the power parameters of a gas heating boiler, use the simple formula 1 kW = 10 sq.m.

This calculation is suitable for a room with a ceiling height of 2.7 m and an average degree of thermal insulation.
