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.

Features

  • Fully room-sealed condensing high efficiency gas-solar water heater
  • 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)
  • 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
SGE

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.

Features

  • Fully room-sealed condensing high efficiency gas-solar water heater with integrated solar heat exchanger
  • 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)
  • Varying water temperature setting from 40°C to 80°C with use of week timer
indirect solar system

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 water heater (calorifier) for solar applications
  • Nominal output: 52 – 87 kW
  • Capacity 389 – 1024 litres
  • Single-wall spiral heat exchanger
  • Insulated access cover for comprehensive waterside maintenance
  • Replaceable magnesium anode
  • PermaGlas Ultra Coat second-generation glass coating technology prevents corrosion
  • ITE 400-1000: Insulated ring base
  • Insulated access cover for comprehensive waterside maintenance
