The problem is that it CANNOT work the other way around where the heat comes on with the blower. Heat strips are […]

Here is another great explanation from Michael Housh of Housh Home Energy in Ohio. Thanks, Michael! I’m going to lay out and compare the sensible heat rate equations for both the air-side and water-side of HVAC to help draw similarities and dive deeper into the science behind these equations. This is the beginning of a […]
