Single-circuit and double-circuit gas boiler.
Single-circuit gas boilers are designed only for heating a house with an area of \u200b\u200bup to 250 m2. This is an ideal option for inexpensive, ergonomic equipment for heating a country house. There are bifunctional single-circuit boilers with a built-in water heater, their installation involves the immediate supply of hot water in those places where it is necessary (for example, a bathroom). The capacity of the water heater varies from 40l. up to 200l.
A double-circuit wall-mounted gas boiler not only provides heating, but also heats water, this option is the best choice for a home where there is no central heating. But, there is a drawback, if you use water in the kitchen and in the bathroom at the same time, the temperature of warm water drops, here the whole family will have to remember this.
Open or closed combustion chamber?
Traditionally, wall-mounted gas boilers for heating and water heating have two types of combustion chambers - open and closed. A gas boiler with an open combustion chamber consumes air for combustion from the room in which it is located, if there is insufficient air intake in the room, there is a possibility of a high oxygen consumption by the gas boiler in the house, which will cause residents to feel stuffy. For this reason, most often a boiler with an open chamber is installed in boiler rooms.
A gas boiler with a closed combustion chamber uses air for combustion from the external environment using a chimney. The boiler always takes as much air as it needs without disturbing the air exchange. A boiler with a closed chamber can do without forced ventilation, in the case of boilers operating on LPG reduced gas, supply ventilation is always necessary in any case.
Installation of a gas boiler.
Gas boilers can be installed in almost any accessible place, for example in the bathroom or in the kitchen. If you have little space, the best gas boiler is a wall-mounted compact size. When installing near living rooms, make sure that it is not loud, especially at night, when you can even hear the operation of the refrigerator.
The boiler must have some gaps around itself in order to function properly without overheating. This is a minimum of 100 mm of empty space from the ceiling and floor, 5-10 mm on each side, 450 mm of empty space in front of the boiler. Installation of wall-mounted gas boilers requires caution; avoid sharp steel corners. The device must be firmly fixed and have a stable connection with pipes and ventilation holes before starting work. Do not forget about grounding and the correct connection of cables - each color of the wire corresponds to another, brown to brown, green to green, black to black.
The control panel is located at the bottom of the boiler, it is open or closed, the closed panel is protected from unauthorized access, it is easy to open by pulling the handle. The sight glass is usually located directly above the control panel, it shows the operation of the gas boiler. Before starting the system, make sure that the power is turned on and the maximum thermostat level is selected, after about 15 seconds. after switching on, the boiler will light up. After a while, you can adjust the temperature you need.
Care and safety.
According to statistics, every year dozens of people die from carbon monoxide poisoning, its presence in the air occurs due to malfunctioning ventilation or lack of maintenance of heating equipment. A few minutes after the leak, its concentration in the air is approximately 70%, causing irreversible changes in the human body. The situation is aggravated by the fact that there are no warning signs, such as a headache or sudden weakness, leading to very sad consequences ...
In order for the gas boiler to be completely safe, the following rules must be observed. Call the service wizard at least once a year for a technical inspection. Long-term non-maintenance operation pollutes the device and leads to malfunction. Regularly check the permeability of the chimneys, do not use mechanical ventilation in the rooms where the boiler is installed. But, where there is an additional source of heat, for example, a fireplace, you should take care of an adequate supply of air.
Replacing an old boiler with a new one is no less responsible than its contents. Choose models of medium or higher prices, the safest models with a closed combustion chamber.
