12 best indirect heating boilers

Among the wide variety of water heaters, buyers are particularly interested in indirect heating boilers. Externally, these models do not differ from conventional storage devices. Most often, manufacturers stop at a rectangular or cylindrical body shape. Indirect boilers have their pros and cons. Experts recommend paying attention to several technical parameters.

How to choose an indirect heating boiler

1. Power heater is selected taking into account the volume of the tank and the desired rate of heating water. When studying the documents on the boiler, it is necessary to consider the useful power of the device.
2. Spaciousness The water tank depends on the number of users. To take a shower in the country a couple of avid gardeners and gardeners, enough 100-liter drive. If the family is big, there are small children, then it is necessary to give preference to more spacious boilers (200-300 l). But at the same time, the capacity of the heat exchanger must be greater so that the water heating does not take long to last.
3. Heating rate also depends on the area of ​​the heat exchanger. To find the optimal combination, you can build on the following relationship. The rate of heating water of 120 liters with a coil area of ​​1 square. m will be about 30 minutes.
4. Reliability and durability boiler is largely determined by the quality of manufacture of the tank. The stainless steel tank will last the longest, but the price of such models is high. Tanks of ordinary steel manufacturers enamel or glass-ceramic. Magnesium anodes also help to resist corrosion, they also protect the internal cavity from the formation of scale.
5. Keep the temperature water at a given interval helps heat insulation. Low-cost boilers have a foam layer, more modern products are equipped with polyurethane foam insulation.
6. Functionality. Various options help minimize human intervention in the boiler. It is overheat protection, safety valve, thermostats and thermometers.
7. Number of water intake points. With the help of a boiler, you can hold hot water in several rooms. To do this, select a water heater with several points of water intake.
