According to numerous sources, 68 degrees F is the magic number in winter. That's not to mention the money that goes toward keeping a home and those who live in it cool when the weather turns warm, an effort that reflects roughly half of a household's energy costs during summer months. I can see the recovery rate being less when the geothermal/desuperheater isn't in use (since the water from the preheat tank is colder). Of course, it's possible that the smaller tank could have a better first hour rating and recovery rate, but I'd check the specs to be sure. Then we have to use more hot water to compensate when taking showers. I haven't talked to my installer yet because I wanted to see what happens as it gets colder. Mine would be: Perhaps more people should be using combination (water and air) heat pumps or zones to get 100% of DHW.
