When choosing a suitable indirect water heater, experts recommend taking into account several factors:

• Volume of the tank. On average, a family of 3-4 people need a tank of 100 to 150 liters to ensure an uninterrupted supply of hot water. With low consumption, models with a smaller useful volume are suitable, but if the consumption is high, you should pay attention to the larger and more productive versions.
• The possibility of installing a heating element will turn the device into an ordinary electric water heater. This is true in the absence of centralized heating in the summer.
• Internal coating - it can be of three types: stainless steel, enamel or titanium. Versions with the first two types are more common, while at least 1 magnesium anode is required, which provides anti-corrosion properties.
• Heat exchanger design. One coil in standard configuration, two in models with connection to an alternative source of heating medium. Coil-in-coil is a more expensive but effective option.
• Additional functionality. Convenient when the model is equipped with sensors, automation, thermometers, turn-on indicators at the factory or as an option. There are also important safety functions - protection against overheating, switching on without water.
• Number of tapping points. Most often, there are models with two outlets for supplying hot water, which allows it to be brought out at once to several separate rooms, for example, to the bathroom and toilet or kitchen.

In addition to the above, indirect heating boilers differ in the way of connection and installation. It is better when the model can be connected to a boiler or any type of heating system. The installation is divided into two types: wall and floor, subdivided into vertical and horizontal. There is also a difference in the side of the coolant supply. All this should be taken into account when planning.
