Choosing a gas boiler is an excellent solution that will improve the comfort of your home in the next 10-15 years. This article shows in detail what you need to pay attention to when choosing a burner.
1. The tightness of the boiler is significant
The first and most important thing is to properly manage the necessary tension. There is a simple formula: 1 kW of tension per 10 m² of area with a bed height of up to 3 meters.
Butt rozrahunku:
- Booth area: 150 m²
- Power required: 150 / 10 = 15 kW
- With reserve (20%): 15 × 1.2 = 18 kW
It is important to take into account additional factors: the degree of insulation, the thickness of the windows, the region of residence. For cabins with poor insulation, the tension reserve factor should be increased to 30-40%.
2. Single-circuit or double-circuit?
Single-circuit boiler
The purpose of this is for scorching . An ideal option if you already have a large hot water boiler or are planning to install one.
Advantages:
- Simple design
- The most reliable robot
- Easier in service
- Нижча ціна
Double-circuit boiler
Provides scorching + hotter water supply . A compact “2 in 1” solution to save space and budget.
Advantages:
- No boiler required
- Економія місця
- Lower quality of the system
Недоіки:
- GVP productivity is limited (8-15 l/hv)
- Not suitable for great homelands (4+ specialties)
- When a number of cranes are pressed for one hour, the pressure drops
3. Camera type
Vidcrete chamber (atmospheric boiler)
Taking air from the fireplace from the premises will require a classic chimney and good ventilation of the boiler room.
- ✓ Nizhcha tsina
- ✓ Simple design
- ✓ Energy independence (all models)
- ✗ A vertical dimokhide is required
- ✗ Obov'yazkova okrema boiler room
Chamber closed (turbocharged boiler)
It takes air from the street through a coaxial flue. The products of the fire are taken out with a Primus stove behind the help of a fan.
- ✓ Classic Dimokhid is not required
- ✓ Can be installed in any location
- ✓ Greater KKD
- ✓ Bezpechnіshiy
- ✗ Вища ціна
- ✗ Availability of electricity

5. Condensing boilers - future technology
Condensing boilers are a premium class of combustion technology with an efficiency factor of up to 109% . How is it possible? The secret lies in the heat of condensation of water vapor from combustion products.
Savings with a condensing boiler:
During the burning season (180 days), a 150 m² cabin burns approximately 3000 m³ of gas. A condensing boiler saves 20-30% of fuel - it costs about 600-900 m³ of gas or 15,000 - 22,000 UAH per river (at a price of 25 UAH/m³).
6. Top 5 brands of gas boilers 2024
- Vaillant (Nimechchina) - a standard of sweetness and reliability
- Bosch (Germany) - innovation and efficiency
- Ariston (Italy) - optimal price/capacity
- Baxi (Italy) - compactness and functionality
- Protherm (Slovakia) - affordable prices, good quality
7. How to increase your respect
Automation and control
Modern boilers are equipped with weather-dependent automation, Wi-Fi modules for remote heating, and programmable thermostats. This allows you to save up to 25% on gas .
Protection system
Turn the truth around:
- Frost protection
- Protection against overheating
- Traction control
- Half control
- Protection from pump blockage
Modulation of tension
Boilers with modulation automatically adjust heat according to demand. The most important thing is to service the property and save gas.

The choice of a gas boiler depends on many factors: the area of the booth, the number of people, the availability of the flue, the budget. For a cabin up to 150 m² with 3-4 bags, the best option is a double-circuit turbo boiler with a power of 20-24 kW of a verified generator.
