The solution

It’s no exaggeration—this solution is on the leading edge of its generation! Combining home heating and hot water production with a condensing water heater coupled with a water storage tank, meets all the building’s needs efficiently. And since the air conditioning in each apartment is produced by the cold water network, it’s a totally innovative, competitive design! What’s more, the compact fan coil in the ceiling space of each dwelling diffuses warm and cool air via the minimalist duct design. This concept, intended for 50-unit buildings as well as for smaller ones, achieves a standard of comfort in each apartment while reducing the number of air outlets. In short, a comfortable, competitive new solution!

Optimal solution set-up

1- Compact fan coil
  • Compact, can be installed in the ceiling space 
2- Condensing water heater coupled with a storage tank

The minimalist duct revolution

Did you know that warm air can be diffused from high up on a wall opposite a glass surface without sacrificing comfort—and in both heating and cooling mode? The minimalist heating duct design, as it is called, reduces the required length of the air ducts, creating a compact heating design.
