Even if insulated, isn’t this setup always heating the home? The insulation slows down the heat transfer but if I’m following correctly it’s basically running the heat element anytime the sun is up. I think this would be counterproductive in my climate as I’m cooling the home most of the year which is an even more energy intensive process
Hrm. You probably know better than me, but I always assumed that since my cooling cost in Summer is 5x the cost of my heating cost in winter (with similar differentials, eg. heat+30 degrees, cool-30 degrees) that it was a less efficient process.
The napkin math still doesn't make since if I have to increase the cooling of house ~half the day (would be more since summer has longer days.) Other considerations would be extra wear on the HVAC equipment and just the comfort impact of increased fluctuations.
All cooking appliances are heating the home if you view it in that lens. Fridge, normal cooktop, oven, airfryer, dishwasher.
