Ventilation systems with heat and moisture recovery
Extremely economical and quiet, yet large power reserves to have the best indoor air quality even at a large party. Is of course part of the basic equipment.
For 3 decades I have observed that ventilation systems with heat recovery almost do not spread because of absurdly high prices. Here I explain why a ventilation system, which every ventilation engineer would call “The mother of oversizing”, is the most economical solution and belongs to the basic equipment of a “GEMINI next Generation” house.
