Alumini® Extremely compact condensing heat exchanger

The Alumini heat exchanger is a compact, cost-effective and lightweight residential aluminum heat exchanger in capacities up to 38kW.

With its small dimensions, it is perfectly suitable for use in compact, wall hung boilers. It provides a high output to comply with the latest requirements for use in residential condensing boilers. The Alumini® is an aluminum casted monobloc. Aluminum has an excellent thermal conductivity giving eight times better heat transfer coefficient compared with stainless steel.

The heat exchanger is casted, so there are no internal gaskets required. It has a fully water cooled combustion chamber design and therefore no ceramic insulation is needed. It has large and simple water channels resulting in low hydraulic resistance. They reduce your risk of clogging and scaling.


  • High output range in a very compact housing
  • Reduce the risk of clogging and scaling
  • High flame stability over the whole capacity range
  • High modulation range and low pneumatic resistance
  • Can be combined with gas adaptive systems


  • Condensing wall hung boilers for central heating
  • Condensing combination boilers


The Alumini can be combined with a Furinit burner. The Furinit is the most compact, premix gas burner using specific shape features in combination with the Bekinit® material. It is especially designed for compact combustion chambers with limited space.
