Condensing gas boilers with connection to external storage tank

section-header-2.png

The series of "With connection to the external storage tank" boilers uses a built-in three-way valve for the option to heat water in an external storage tank. This type of boiler operates in the same way as the series of “Only for heating” boilers. Due to the wide range of models and quantities of indirect heating heaters, this type of heating produces a relatively high volume of water.

Sources of this type are recommended sources of heat for heating systems for new buildings, low-energy houses and residential units. They achieve a maximum efficiency of 108% in combination with floor heating. Outdated gas boilers can also be replaced with the existing heating system.
