I am in the design process of what will be a retirement home. The property is 43 acres near Perth, Ontario. The home will tentatively be off grid. I'm thinking a solar/ wind hybrid system. I was leaning towards an air to water heat pump as the heating system, but a masonry heater as a primary when we are home. I am considering the Legalett system that you discuss in many of your articles. They have a heat exchanger that goes from liquid to their air distribution system. Would this be compatible? Are there unnecessary inefficiencies in going from air to liquid and back to air, and if so, how to remove them? Should I just go straight to hydronic with glycol and forget the Legalett air distribution part but keep the forming? I'm trying to achieve the least amount of electrical use required to make the in floor system work. Pumps vs fans, liquid vs air for heat transfer, such a complex comparison! Advice please.
