TOP 19 best indirect heating boilers according to customer reviews

If you live in a private house or have installed an individual heating system in your apartment, you simply cannot do without an indirect heating boiler. This device allows you to get the right amount of warm water without connecting to the mains. The required parameters are achieved by heating with a heat carrier 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 free sale. All of them have both undoubted advantages and disadvantages. Let's consider them in more detail.

Selection options

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

Volume of the tank

First of all, this parameter depends on which heating boiler will be connected to the common circuit. In addition, you should pay attention to the daily needs for hot water. An incorrectly calculated parameter can lead to the fact that it will simply be impossible to use hot water at several water points at the same time.

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

Heat exchanger device

There are two versions:

Two tanks placed one in the other. The inner one is filled with water. And a coolant circulates along the outer contour space, providing heating.

Coil system. One coil is used as standard. However, there are models where there are two similar elements. Thus, the boiler can be connected to an alternative heat source.

The presence of heating elements

You should pay attention to this if you want to use hot water not only during the heating season, but all year round. If alternative coolant supply is unavailable, the device can operate as a conventional electric boiler, from the mains.

Tank material

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

Operating pressure

This indicator is especially important for units installed in apartments. Central heating, unfortunately, cannot boast of the lack of regular surges in the system. So it is better to choose models with a safety margin.

The best models with a heat exchanger

You can use such boilers only in the winter, as the water will be heated only from the boiler. But you will not spend a penny of extra money, because there will be no additional costs for electricity.
