In winter, heating and hot water take away the lion’s share of the family budget. A modern gas boiler will help save money. The device quickly heats the room, consumes little fuel, does not spend too much if the temperature in the house has become comfortable.

How to choose a wall mounted gas boiler

Types of units:

1. Single-circuit – are intended only for heating the area up to 350 m².
2. Double-circuit – heat the room and heat water.

Type of combustion chamber

• Open (with chimney). Combustion air comes from the room where the appliance is installed. Carbon monoxide leaves under natural draft in a vertical chimney, the height of which must be at least 4 m.
• Closed (turbocharged boilers). Air is supplied and discharged by a fan – turbine. It simultaneously draws in air from the street and emits carbon monoxide there. This option is suitable for urban apartments..

Heat exchanger material

• Carbon steel. Not the best material, because condensate is constantly forming on the walls of the tank, which oxidizes the steel, which leads to rapid damage to the boiler. Replacing a heat exchanger often reaches 50% of the unit price.
• Copper. This material is rust resistant. The heat exchanger from it is lighter, less voluminous, but in reliability inferior to steel.
• Cast iron – strong, but heavy, so it is used for floor models.

Other options

• Power. It is recommended to take a wall-mounted boiler at the rate of 0.3 kW per 10 m². Much depends on the climate, insulation of the house and other parameters. In order not to make a mistake, add 20% of power to the final digits.
• Type of ignition – electric or piezo. The first method is more economical and safe. If a piezoelectric element is installed, the fire must be maintained constantly.
• Autonomy. Most gas wall mounted units are dependent on electricity. Without it, the circulation pump does not work, the ignition does not work. To protect equipment from power surges, you need a stabilizer or uninterruptible power supply.
• Adjustment – mechanical or electronic.

Most popular models

Bypass systems are in demand, which are designed to heat an area of ​​up to 250 m². When choosing a budget model, give preference to reliable brands (Bosch, Protherm, Vaillant). Their boilers are high quality assembled, reliable, durable, easy to operate..
