  1. EOLO Extra kW HPWall hung boiler with condensing heat exchanger, for high temperature systems

  2. Main features • New models • Functioning • Efficiency • Dimensions and connections • Control panel • Applications • Outdoor installation • Main Option kits • Availability and list price

  3. New Models Immergas expands its range of condensing boilers with the new EOLO Extra kW HP range. The new boilers are characterized by the presence of a traditional heat exchanger (copper made) combined to a special condensing heat exchanger.

  4. Applications New versions EOLO Extra kW HP represent the Entry Level in the Immergas condensing range. This solution takes the advantages of the condensation technology and it represents the best choice for residential new buildings (where price assumes detail relief) or in case of traditional boiler substitutions.

  5. Features • Two models with heat outputs of 24 e 30 kW • Instantaneous production of D.H.W • Designed for traditional systems, working with high temperatures only (for example radiators). • Outdoor and indoor installation (IPX5D)

  6. Features • Special condensing heat exchanger, located downstream main heat exchanger • Remarkable structural simplicity, thanks to a conventional boilerlike frame • High efficiencies • Compact dimensions (25 cm depth)

  7. Functioning The structure is completely similar to a traditional boiler with copper heat exchanger, to which a special Aluminium condensing exchanger has been added in series. Heat Recover

  8. Functioning The heat recover absorbs a further part of the heat contained in the fumes, allowing to preheat the water before the primary heat exchanger. Heat Recover Primary Heat Exchanger Condensate drain pipe

  9. Efficiency • Efficiency targets are analogous to ones of Condensing Boilers • Efficiency at nominal heat output (80/60 °C): • EOLO Extra 24 kW HP = 97,3 % • EOLO Extra 30 kW HP = 96,4 %

  10. Dimensions and connections • only 25 cm depth • standard provided with anti-freeze -5 ºC (-15 °C with option kit)

  15. Applications The main difference with the condensing models is that EOLO EXTRA kW HP are designed for traditional systems, working with high temperatures only (for example radiators).

  16. Applications The EOLO Extra kW HP models can’t be combined directly to underfloor panels (low temperature systems).

  17. Condensing drain • Simple condensate disposal, thanks to built siphon, similarly to other condensing models

  18. Outdoor installation The boiler can be installed outside, in partially protected places (for example under a balcony); the protection index is IPX5D.

  19. Climatic thermoregulation (optionals) Amico Remote Control (CAR) External Sensor • Central heating temperature modulation according to the external and internal temperatures means lower consumption

  20. Super CAR Remote Control (optional) • Climatic programmer and modulating room thermostat • Easy to use thanks to a wide display and only one setting knob

  21. Option kits • Connection kit cod. 3.019329 • Anti-freeze protection kit a -15 °C cod. 3.017324 • Cover kit cod. 3.016022 • Additional 2 litres expansion vessel cod. 3.016224 • Telephonic Remote Control cod. 3.013305 • DIM range

  22. Flue pipes green range EOLO Extra kW HP can be matched to the same flue pipes for the other Immergas condensing models; the main kit options are: • Twin pipe kit Ø 80/80 cod. 3.012002 • Concentric horizontal kit Ø 60/100 cod. 3.012000 • Concentric vertical kit Ø 60/100 cod. 3.016833
