Gas home equipment
In private homes, gas is used to heat homes and get hot water. Therefore, very carefully it is necessary to approach the choice of equipment. Otherwise, if you change the boiler or column, you will need to make adjustments to the gas project of your house. Most often, a column is installed in the houses, for heating water and a boiler for heating the premises. It is rather difficult to purchase two devices and install them separately, taking into account technical requirements. The simplest way is to buy a dual-circuit boiler that will warm up the housing perfectly and provide consumers with hot water. This option is well suited for standard houses with one bathroom. If the house is a large area and there are several bathrooms in its layout, you should equip your own mini boiler room, but this is a different matter. When choosing a heater, it is necessary to calculate the required power of the device. For this, it is necessary to take into account a number of factors:
- the climate of your region;
- the area of the house;
- heat loss;
- the required amount of hot water.
So, the power of the boiler can be calculated by the following formula:
MK = S * UMK / 10,
where MK is the capacity of the heating boiler;
S - the area of the house in sq.m;
UMK is the specific capacity of the boiler, it is set for each region separately. This indicator is:
- for the southern regions 0,7 0,9 kW;
- for the middle band 1.0 1.2 kW;
- for the northern regions 1.5 2.0 kW;
- for Moscow and the region 1,2 1,5 kW.
Calculating by this formula we find that for a house of 200 sq. M located in the southern region, a boiler with a capacity of 16 kW is required. It should be remembered that it is not necessary to install a too powerful heating device. This threatens a greater fuel consumption and a strong overheating and dehumidification of the air in the room. Therefore, choosing a boiler is better than the required capacity, then it will serve you for many years with faith and truth.
Gas boiler for heating houses, how to choose
If you own a private house, then gas heating is the most optimal option. This is the most economical type of fuel and heating systems are reliable. All gas boilers can be divided into two types:
- wall;
- floor.
Wall-mounted boilers are most convenient. They are mounted on the wall, they have small dimensions. And according to technical data they are not inferior to outdoor analogues. The first kind of devices are installed in any suitable place of the house or they are assigned a separate one for them. Boiler room. Typically, these are cumbersome models that can take up enough space. This is their main disadvantage, especially if they are installed in small rooms. By type of device boilers are divided into:
- single-circuit;
- two-circuit.
To save money and space, dual-circuit models should be preferred. They work not only for heating the premises, but also for the production of hot water. In the warm season, when the heating is off, it is necessary to switch the mode from "Winter" to "Summer" and the boiler will act as a column. It is very convenient and functional. Also, one should not forget about safety, because heating boilers are related to high-risk equipment. Preference should be given to models with electronics that will regulate the gas pressure in the system. Disconnect gas when blowing the burner, report fuel and water leaks, and monitor the temperature. This will help you safely use the equipment and quickly troubleshoot the system.
Two-circuit gas boiler for heating a private house
Two-circuit devices are called devices providing heating of premises and supply of hot water to the consumer. The principle of operation of this type of model is based on heating the water with two circuits. The first supplies hot water to the heating system, and the second heats it for consumption. Also there are two-circuit models with a biothermal heat exchanger. They are two tubes, one is inserted into the other. Water from the inside goes to hot water supply, and from the outer tube the liquid enters the heating system. There are still differences in the type of burner:
- open burning occurs due to the access of oxygen from the room, and the combustion products are removed through the chimney;
- closed combustion occurs due to oxygen and a coaxial chimney (air for combustion of gases comes through the chimney pipe from the street).
To date, the market presents a variety of models of boilers. All of them are distinguished by countries' producers, capacity and, of course, price. Let's consider the most optimal models of devices.
CONORD KSTS GV 12N -floor two-circuit model of domestic production with a power of 12 kW. It is quite enough to heat the area of 120 sq.m. The manufacturer claims a service life of at least 15 years. The advantages of the device include:
- affordable price;
- ease of installation and operation;
- works well at low gas pressure;
- resistant to temperature changes.
The price of the boiler is 18-20 thousand rubles. This model will be an excellent option for heating and hot water supply of a small house.
From the wall models, the following cauldron should be noted.
VAILLANT TURBOTEC PRO VUWINT 24 - 2 3 H -the German production model has the ability to control the temperature for hot water supply. The control panel is located at the bottom of the case and is closed with a cover. Boiler control is easy and convenient. The design of the device is pleasant and looks good in the room. Another nice feature of this device is a system of self-diagnosis and troubleshooting. The only thing that must be considered is the water quality. If you are not sure about the water, it is better to install a filter at the system input. This will help to avoid trouble. The cost of this model varies from 53 to 59 thousand rubles.
Single-circuit gas boiler for heating a private house
These models perfectly cope with the heating of houses. As fuel, they consume the main or liquefied gas, which burns with the release of heat. It is transferred to the heat exchanger through which the heat carrier passes, most often water. Which spreads throughout the system giving away heat, thereby warming up the rooms of the house. Such a system is simple and reliable in operation. When choosing a boiler it is necessary to be guided by the reliability of the manufacturer, the safety system of the device itself. Currently, there is a large selection of single-circuit models on the market. Consider the best of them.
AOEV 23.2 - 3 Comfort -this is a floor boiler produced by the Zhukovsky machine-building plant. The power is 23.2 kW, which will ensure a good warming of the house with an area of 230 sq.m. Also, the boiler is easy to operate, economical. Is able to work well with low gas pressure. The price of the model is 22 thousand rubles. This is a great option for a private house.
PROTERM Bear 40 TLO -a Slovak-made boiler with a capacity of 40 kW. The advantages of the device include:
- independence from the grid;
- external control panel; protection system against overheating and flame control.
The only drawback is the exaggerated price of the model from 74 to 110 thousand rubles. And otherwise it is an excellent solution for heating the house, besides if you buy a boiler and install it on the boiler you can use hot water.
Two-circuit heating, what is it?
To install this heating system, it is necessary to use two-circuit heating boilers. Such systems can differ in the type of water heating:
- direct-flow water is heated while traveling through a heat exchanger;
- indirect heating is possible with the use of boilers, from which water enters the system.
As with any system, there are advantages and disadvantages here. The positive features include:
- saving money by purchasing one device;
- the possibility of using different types of strapping.
The disadvantages are:
- if there is a breakdown, there will be no heating or hot water;
- the need to drain cool water for the receipt of hotter.
It must also be taken into account that the heating circuit must be closed with a constant volume of water. A hot water circuit needs to be recharged, so it is advisable to install a boiler in which there will be accumulation and warming up of water for domestic needs.
Single-circuit house heating
Single-circuit heating is very simple and easy to assemble. Water passes the path from the boiler and passes through the pipes in succession into each radiator and then returns to the boiler. The only drawback is getting less heat from the last radiator. In a private one-story house, you can do without horizontal piping. When installing it, it is necessary to provide an inclination angle for the entire system. Also put radiators strictly in one plane, so that there is no difference in altitude. This scheme is not as simple as it seems and it is better to entrust it to specialists, otherwise some part of the house will remain cold.
For two-story houses there is a vertical wiring. The distribution of the flow goes along the installed riser, which is mounted before the first radiator. Such a system can be made gravity, but it is better to install a pump that will force the coolant through the pipes. Mounting the pump will help to not calculate the angle of inclination of the system and use pipes of small diameter. Installation of a single-circuit heating system requires consideration of many nuances, so it is better to seek help from specialists and enjoy the warmth of your home.
