They provide homeowners with a more convenient and affordable option to keep their homes warm during the winter months thanks to their high efficiency, small size, and cutting-edge features. Modern turbo gas boilers are definitely worth taking into consideration, whether you’re looking to install a new heating system in a newly constructed home or upgrade your current one.

What are the turbo gas boilers

The boiler that produces heat is a turbine gas unit that also has a forced air exchange system installed. Owing to this characteristic, it is not necessary for it to have an air exchange system or a complete chimney shaft. к. A coaxial chimney serves as the means of communication with the external environment.

Coaxial chimneys are combined structures made of pipes nested one inside another of varying diameters. They typically arrive in delivery sets with boilers. The central channel, which is the smaller pipe, is used to exhaust combustion waste products, while the outer channel, which is the larger pipe, is used to take in oxygen.

Turbo boilers can be installed in both private homes and urban apartments because they don’t require the room to have good ventilation.

The primary and possibly only major drawback is that they are solely energy-dependent because of the turbine’s presence and more sophisticated automation.

Device and principle of operation

Although the turbo boiler’s basic construction is largely the same as that of its predecessor, the addition of auxiliary units causes some design modifications.

The closed combustion chamber receives the air required for combustion directly from the street. Exhaust gases have no effect on the interior microclimate because it is separated from the living area and only directly connected to the coaxial chimney.

By producing excessive pressure, the fan (turbine) makes sure that the smoke is released outside the house without the need for smoke extractors (turbocharging).

Because the turbine fan speed is automatically controlled, the gas-air mixture’s composition stays ideal even when the gas pressure in the main line drops. The revs are instantly changed to provide the right amount of thrust and air as the power changes. By doing this, the ideal burner operating conditions are preserved, enabling the maximum amount of energy to be released from the fuel.

Atmospheric or turbocharged: which one is better

The air intake for gas combustion in a conventional atmospheric boiler comes from an open combustion chamber. This implies that fresh oxygen must be added to replace all of the depleted oxygen. You need supply and exhaust ventilation for this.

An adequate supply and exhaust ventilation system are necessary for the atmospheric gas boiler to operate normally. The fuel will not be able to burn all the way through, which will prevent the heat carrier from receiving any heat at all. Secondly, life-threatening carbon monoxide (CO) will form in the room.

Consequently, it is preferable to select a turbo boiler for small buildings where it is difficult to designate a separate, vertically chimneyed, ventilated boiler room from the living area. It is also, generally speaking, the only choice for the gas heat supply of offices, high-rise buildings, and small commercial areas.

Reviews of household models with forced air exchange: advantages and disadvantages

Based on the opinions of turbo gas boiler owners, the following benefits and drawbacks can be identified:

By connecting to the turbo boiler voltage stabilizer and a backup power source, such as an electric generator that runs on gasoline or diesel, and a "uninterruptible power supply" (UPS), power supply issues can be easily avoided. It should be remembered, though, that this will require more material outlays.

How to choose a turbo gas boiler for heating a private house

Wall-mounted or floor standing

• floor standing – more versatile and durable, as the design is unlimited in weight, they are often installed durable cast iron heat exchangers.;
• wall-mounted – compact and lightweight, medium and small capacity (10-50 kW) boiler units, often with higher efficiency than floor standing models. However, due to weight requirements, they use less corrosion-resistant steel and copper heat exchangers.

Furthermore, wall-mounted boilers simplify and lower the cost of installation because they house all the heating system’s components in one housing (expansion tank, circulation pump, safety valve, air vent, etc.). Rarely do floor standing models come with every module that’s required.

Single-circuit or double-circuit

The number of circuits in the turbo boiler determines its functionality:

• single-circuit – its possibilities are limited to heating only;
• two-circuit – in addition to heating, it also heats water for domestic needs.

A two-circuit boiler combines a flow heater and a boiler so that the room’s heating is halted while the hot water is being supplied. It is important to note that the temperature in the house is maintained because, in contrast to popular belief, the coolant does not have time to cool down during idle time.

Although the two-circuit version is obviously more expensive by 10% to 30%, it is still more profitable than organizing the hot water supply in any other manner, such as using a boiler and a single-circuit boiler. Additionally, one of the circuits can be turned off if necessary, such as in the summer when the house doesn’t need to be heated.

Type and material of heat exchanger

The heat exchanger’s composition has an impact on how long the boiler lasts:

• cast iron (service life of 25-30 years and more) – the most heat- and corrosion-resistant metal, but fragile and heavy, so it is used only in floor models;
• copper (service life 12-17 years) – very light and heat conductive metal (it heats up and cools down quickly), weakly corrosion-resistant, but it can burn through.
• steel (service life 10-15 years) – metal is well tolerated for transportation, t. к. not sensitive to physical impact, light and inexpensive to produce, but prone to rust formation, which over the years leads to leaks.

Separate (one heat exchanger for each circuit) and double-bithermal (DHW circuit passes through the main heat exchanger) are the two types of heat exchangers used in two-circuit boilers. Although the last option is less expensive than the others, its reliability is lower. It is nearly hard to remove the scale that has built up inside of it, and this is what frequently leads to early failure.

EFFICIENCY

Even though the "net" efficiency of an atmo-boiler (90–92%) and a turbo-boiler (92–95%) is nearly equal, the latter will have a higher gas consumption efficiency.

The key is to use a coaxial chimney because the heat from the smoke (between 100 and 130 °C), which exits through the inner cavity of the same pipe, causes the cold air from the street to warm up before it enters the combustion chamber. As a result, less energy is required for additional heating. Gas consumption can also be influenced by adding more effective air supply and draft control.

Minimum required power

A straightforward formula can be used to determine the turbo boiler’s power requirements: 1* kW of energy per 10 m 2 of heated area.

* Heat losses from the typical Russian strip for a typical residential building with ceilings as high as 2.7 meters.

For instance, a standard Moscow region home with two bricks of masonry, a 2.7 m ceiling height, and 120 m 2 of area would require a minimum of 120÷10×1=12 kW of turbo boiler power.

To avoid operating the unit at its maximum, we advise setting aside 15–25% of this value; for the same object, this means Q≈14–15 kW.

Furthermore, if we take into account a two-circuit model, the use of DHW will need to increase by at least 15%–20%, resulting in a total of Q≈16–17 kW. Avoid using too much power, as this will cause the boiler to "beat," or turn on and off, too frequently, depleting its resources.
