Residential buildings
The ITS is fitted with 2 coils. In the solar alignment the upper coil is connected to a water heater or boiler. This water heater or boiler
provides the pre- or after heating if the solar contribution is not
sufficient. The lower coil of the ITS transfers the heat from the collectors. This indirect solar system has a high comfort level because the water heater or boiler as well as the collectors transfer the heat to the ITS.
An ITS solar system is a very suitable application in residential and small commercial properties. This system will provide the needed hot water in a very energy efficient manner.
