What is hot water in a heating boiler?

Every person wants to provide themselves with heating and warm water. However, to do this you need to know which system is responsible for this and how to configure it correctly. What is hot water in a heating boiler? This will be discussed in this article, and we will also look at the pros and cons of the device.

What it is?

Hot water supply is a system that allows you to supply users with water at a certain temperature (up to 75 degrees). It is most often used in residential buildings or industrial facilities. DHW is considered an important device because with its help it improves not only the living conditions of the population, but also the quality itself.

Types of devices

There are several classifications. Let's look at each of them:

1. If we evaluate from the point of view of the degree of centralization, then two types can be distinguished. These include local and centralized. The first of them is installed exactly where consumption occurs. The other system is prepared at the heating point itself. And additional pipes are already connected to it, which are able to deliver the desired liquid to users.
2. In addition, there are two models that differ in the degree of preparation. Thus, single-circuit and double-circuit cycles are distinguished. One of the presented heat sources is water at elevated temperatures, and the second also has steam.Naturally, the process of a boiler with one circuit is much simpler than the same one with only two. The presented types of systems are also called open and closed.
3. The last division is based on the use of recycling. It can be either with its absence or with its presence. That is, in the first liquid, if it is not lost, it cools down due to the transience of time. This type is convenient for using small networks with pipelines. In the next case, water up to 35 degrees, which was not used, is diverted specifically for reverse heating.

IMPORTANT! It works only when the local system is more than 2/3 of the entire length.

Advantages and disadvantages

To really determine the characteristics, you need to differentiate between the pros and cons. The first category includes:

• Thanks to modern technologies, high energy efficiency is achieved.
• Some designs have a low cost, which indicates the availability of purchase.
• Low rate of deposits in pipes and metal corrosion.

Speaking about possible defects, it is worth mentioning:

• Required accuracy in open system calculations. This may cause difficulties in interacting with the unit.
• In addition, the state of the double-circuit design is much more complicated than with a single circuit.
