To create a cozy atmosphere and a comfortable stay in your own home, heating plays an important role. No matter how expensive and with what kind of design repair the apartment may be, living in it will turn into torture if the indoor temperature during the off-season is equal to the outdoor temperature. It is so nice to return dank in the fall or fierce winter to your own apartment or house, if it is dry and warm.
During construction or major repairs, great attention should be paid to the selection and purchase of a heating system. And if the pros and cons of choosing a fuel are usually obvious, then you need to reflect on the functionality of the purchased device.
Difference of a double-circuit boiler from a single-circuit
How does a double-circuit boiler work? Already from the name of the types of heating boilers, their distinguishing features are intuitively clear. The single-circuit boiler is connected to a closed system of batteries or radiators and uses energy only for heating the room.
The water heated by such a boiler circulates in a circle and is not used for any other domestic needs.
What is a double-circuit boiler? In the absence of a centralized supply of hot water, you will have to think separately about organizing its heating for the kitchen and bathroom. Dual-circuit devices work on a different principle and are divided into two types.
- Flowing water heating.
In standard mode, it works to heat the room. If you need to take a bath, you need to switch the toggle switch on the boiler body. Thus, the bulk of the energy will be directed to heating the water, which subsequently flows from the tap. It should be borne in mind that heating is performed "in real time" and this solution is suitable for small areas. The optimal size will be up to 100 square meters.
- Boilers of the second type have a storage boiler in which water is directly heated and stored. Due to the constant maintenance of high liquid temperatures and a rather large volume, the amount of water is enough for a comfortable quality of life for a large family. If necessary, the boiler can function in the mode of flow heating. However, the water temperature will be slightly lower than that of the liquid from the storage.
Important!You can independently choose the amount of stored fluid. Depending on the model of the boiler, it can be from 100 to 250 liters.
The principle of operation of a double-circuit boiler
The principle of operation and the device of the dual-circuit boiler is such that it can operate in two modes: heating mode and water heating mode.
In the first case, energy is transferred from the burner to the liquid in the heating system. Thanks to the valve, water circulates in a closed system using a pump, returning chilled in the return pipe line.
When the valve is closed, the heated fluid enters the water supply. That is, when the tap is open, the heating system of the house does not work. And as soon as it closes, heat immediately rushes into the batteries. Thus, two systems cannot work simultaneously.
The boiler may contain either one or two points of water intake. That is, provide a kitchen, bathroom or both rooms.
Pros and cons of the dual-circuit model
The pluses of the dual-circuit model include:
- Small dimensions. Such a boiler takes up quite a bit of space. Since you do not need to buy additional components, you can immediately plan;
- No need for a separate room. All piping can fit compactly in one secluded place;
- Easy to use
- Economical fuel consumption for heating.
The disadvantages of this model are as follows:
- When working on two sources of water supply, pressure and temperature may be lower than desired;
- Maintenance. With a high content of metal salts in local water sources, water heating elements quickly become covered with a layer of scale. To prevent equipment breakdowns, regular cleaning is required;
- Cost. Based on the configuration of the model, the cost goes more.
Complete set of double-circuit boiler
Such a device is already in the factory configuration is an independent system. To install it, you do not need to purchase additional tanks, pumps and valves. It is enough to buy the proper footage of pipes for supplying and discharging water and fasteners. Install such a boiler in your home and enjoy the heat.
