19 best indirect heating boilers according to customer reviews

indirect heating. This device allows you to get the desired amount of warm water without connecting to the mains. The required parameters are achieved by heating with the help of a coolant circulating in the circuit.

How to choose a similar device? We have prepared for you a small rating of indirect heating boilers. Each of the presented models can be easily found in the free market. All of them have both undoubted advantages and disadvantages. Consider them in more detail.

Selection Parameters Before we talk about which indirect heating boiler is better to buy, let's look at some points that are worth paying attention to.

Tank volume

First of all, this parameter depends on which heating boiler is connected to the general circuit. In addition, it is worth paying attention to the daily needs for hot water. Incorrectly calculated parameter can lead to the fact that it will simply be impossible to use hot water in several water points at the same time.

In order not to lack hot water, about 70–80 liters of tank volume should fall on each family member. This will not only wash the dishes, but also take a bath without thinking that the water temperature can be uncomfortable. Of course, the power of the boiler must also comply with the calculated parameters.

Heat Exchanger Device

There are two versions:

Two tanks placed one inside the other. Internal filled with water. A coolant circulates around the outer contour space, providing heating.

Coil system. In the standard version, one coil is used. However, there are models where there are two similar elements. Thus, the boiler can be connected to an alternative source of thermal energy.

Availability of heating elements

Pay attention to this if you want to use hot water not only during the heating season, but throughout the year. If the supply of alternative coolant is not available, the device can work as a regular electric boiler, from the network.

Tank Material

There are three modifications on the market: enameled or stainless steel and titanium coating. The latter is much rarer and more expensive. When choosing a tank, you should pay attention to its anti-corrosion properties, as well as the presence of an additional magnesium anode.

Working pressure

This indicator is especially important for units installed in apartments. Unfortunately, centralized heating cannot boast of the lack of regular jumps in the system. So it is better to choose a model with a margin of safety.

The best models with the heat exchanger

You can only use such boilers during the winter period, as the water will be heated only by the boiler. But you will not spend a penny of extra money, because there will be no additional energy costs.
