New ModelsNew 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.

Pre Sales Dept.

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.

Applications

FeaturesFeatures

▪ 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)

Pre Sales Dept.

FeaturesFeatures

▪ 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)

Pre Sales Dept.

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.

FunctioningFunctioning

Heat Recover

Pre Sales Dept.

The heat recover absorbs a further part of the heat contained in the fumes, allowing to preheat the water before the primary heat exchanger.

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).

Applications

Pre Sales Dept.

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

Applications

Pre Sales Dept.

• Simple condensate disposal, thanks to built siphon, similarly to other condensing models

Condensing drainCondensing drain

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