Indirect solar system – ITE Renewables
Indirect solar system – ITE
The indirect solar system ITE consists of an indirect tank which is connected to a boiler (electric, gas or oil) or water heater. The optimum installation can be constructed by using different accessories. The ITE (as well as the ITS) can be part of a solar water heating system. It can be installed with or without a drainback system. Features Indirect solar system ITE

A SGE
SGE is a compact installation with integrated solar heat exchanger. Apart from its excellent suitable size for restricted spaces, the SGE is also a very efficient appliance. The collectors are connected to the lower heat exchanger, and the heat is transferred from the collectors to the water. The upper heat exchanger afterheats, if necessary, until the water has reached the desired temperature. In this installation the solar contribution is fully utilized. If a higher draw-off temperature is required than can be provided by solar contribution, only then additional gas heating is needed. This functionality delivers the optimum use of solar energy and a minimum use of gas. Features SGE
- Fully room-sealed condensing high efficiency gas-solar water heater with integrated solar heat exchanger
- Maximum solar contribution through fully integrated intelligent solar controller, heat comfort guaranteed
- Automatic gas/air premix burning system including burner modulation
- Delivered with low-maintenance inert anodes
- Efficiency 96% (gross)
- NOx emission ≤ 30 ppm (dry – air free) – NOx class 5
- Whisper quiet operation (<45 dB(A) on 2m distance from duct)
- One control and display unit for the complete installation
- Easy fault diagnosis and computer controlled digital week timer
- Programmable for legionella purge cycle
- Very small footprint because of integrated solar heat exchanger
- Varying water temperature setting from 40°C to 80°C with use of week timer
- BMS interface for easy connection to a building management system, learn more...
- The SGE is suitable for combining hot water and heating, learn more...
A SGS – solar system with ITE
SGS solar system with ITE is installed in combination with an ITE storage tank with integrated heat exchanger. The collectors are connected to the heat exchanger and the available heat is transferred to the tank. If the temperature of the water in the SGS differs more than 5 degrees from the water in the ITE, the heat transfer from the ITE to the SGS starts up. If necessary, the SGS heats the water to draw-off temperature. In the installation the solar contribution is fully utilized. If a higher draw-off temperature is required than can be provided by solar contribution, only then additional gas heating is needed. This functionality delivers the optimum use of solar energy and a minimum use of gas. Features SGS solar system with ITE
- Fully room-sealed condensing high efficiency gas-solar water heater
- Maximum solar contribution through fully integrated intelligent solar controller, heat comfort guaranteed
- Automatic gas/air premix burning system including burner modulation
- Delivered with low-maintenance inert anodes
- Efficiency 97% (gross)
- NOx emission ≤ 30 ppm (dry – air free) – NOx class 5
- Whisper quiet operation (<45 dB(A) on 2 m distance from duct)
- One control and display unit for the complete installation
- Extra solar contribution possible up to 40% compared to standard solar systems
- Easy fault diagnosis and computer controlled digital week timer
- Programmable for legionella purge cycle
- Suitable in combination with ITE indirect water heaters up to 1024 litres
- For larger applications A.O. Smith developed the IT storage tanks up to 3000 litres
- Varying water temperature setting from 40°C to 80°C with use of week timer
