Gas boilers are a fundamental solution for heating systems in many homes. On the correct choice depends not only on the comfort of living, but also on the safety of the occupants, as well as the economics of operation for many years.
Varieties of gas boilers: features and recommendations on choice
Gas boilers are the most popular solution for heating houses, flats and other objects. When choosing it is necessary to pay attention to the type of boiler, its functionality and area of application. Let’s consider the main varieties of gas boilers and their features.
Single-circuit and two-circuit boilers
- Single-circuit: These boilers are designed exclusively for heating. They are connected to the heating system and heat only it.
- Double-circuit: These boilers fulfil two functions – heating the room and providing hot water. They are ideal for private houses or flats, where you need to solve both tasks at the same time.
If you only need heating, choose a single-circuit boiler. If you’re looking for a complete heating and hot water solution, a dual circuit boiler is the best choice.
Wall and floor standing boilers
- Wall-mounted: Smaller boilers are ideal for smaller rooms. They require less space and are usually less powerful.
- Floor standing: Larger in size, have a higher output and can heat larger areas. Suitable for cottages or larger homes.
The choice between wall and floor standing boilers depends on the size of the room and the required output of the heating system.
Boilers with open and closed combustion chamber
- Open combustion chamber: These boilers use air from the room to burn the gas. Good ventilation is required in the room where the boiler is installed.
- Closed combustion chamber: The combustion air is taken from outside, through a special coaxial chimney.
Boilers with a closed combustion chamber are safer because they eliminate the possibility of carbon monoxide leaking into the room. They are particularly recommended for residential applications.
Key selection criteria
- Capacity: To choose the right boiler, it is necessary to take into account the area of the room and the number and type of radiators in the heating system.
- Type of installation: Wall-mounted boilers are ideal for smaller rooms, while floor standing models can provide more power and are suitable for larger houses or cottages.
- Efficiency: This rating reflects how efficiently the boiler uses gas to generate heat. A high efficiency rating ensures economical consumption.
- Safety: Modern models are equipped with gas leakage control, overheating protection and other features for safe operation.
