Rating of the 8 best gas boilers for home: double-circuit, single-circuit, floor-standing, wall-mounted
No one wants to depend on centralized systems, so many tend to decide for themselves when to start the heating season. Gas boilers are able to help in this. Today, the types and functions of gas boilers are quite wide. There are single-circuit, double-circuit, wall, floor. Each consumer can choose exactly what he needs.
The best double-circuit gas boilers
Double-circuit models are quite easy to use and heat the room with high quality. They also have the function of supplying hot water for domestic needs. Made of durable metal. Almost everyone has a draft sensor. They can withstand high temperatures and quickly heat water. The main disadvantage is their price and the cost of spare parts. Although they break quite rarely, no one is immune from this.
The best gas boilers:

The best floor standing gas boilers
Floor standing gas boilers are in great demand even today. Floor-standing boilers include both double-circuit and single-circuit. They have no power limitations, which in other cases often leads to the inability to achieve a uniform temperature. Such boilers can boast of the strength and reliability of the units. There are no unnecessary additions in them, which greatly simplifies installation. Outstanding representatives of such devices are:
Lemax Leader-16
This is a floor-standing single-circuit boiler. Its distinctive feature is a cast iron heat exchanger. Thanks to this, the boiler heats up rather quickly and heats a large area. Has a high efficiency of 91%. It is a chimney installation. Among the pluses is the transition to liquefied gas and an overheating sensor. The maximum pressure that it can withstand is measured in 4 bar.

The best wall mounted gas boilers
When installing wall-mounted gas boilers, we always deal with risks. All fire safety rules must be strictly followed. Wall-mounted, unlike floor-mounted, are quite compact and weigh little. With such a boiler, it is more convenient to bring the coaxial pipe outside. But in contrast to these advantages, their relatively low power is worth. It is also important to consider that such boilers cannot be installed in corridors, balconies and bathrooms. Notable examples are:

Conclusion
Today there are a huge number of gas boilers. Each of them has its own unique features. Some are suitable for heating apartments, others for communal buildings and summer cottages. They also have different volume, power and other characteristics. Single-circuit ones are more suitable for heating communal buildings. While double-circuit ones have a more developed diagnostic system, a mode of heating water for domestic needs, they are more suitable for apartments.
Also, boilers can be divided into floor-standing and wall-mounted. Wall-mounted ones are easier to operate, but they require compliance with all fire safety standards. They cannot be placed on balconies, terraces, in the bathroom, in the corridor. They have low power, but it is enough to heat the house. They are opposed by powerful, durable, but also very demanding floor standing boilers. High power is fraught with instability of this type of gas boilers. They don't have many mechanisms, which makes them easy to set up. Wall-mounted and floor-standing boilers can be either single-circuit or double-circuit. Boilers have become an excellent substitute for district heating. Thanks to this article, anyone will be able to determine which gas boiler is best for him.
