I did not see any reference to my question and would appreciate a response as soon as possible, as due to medical situation, have to make a decision soon. We own an OLD house with 13′ ceilings in a large part of the home and 11″ ceilings in the LV/DR and BR. We are oscillating on where to place the ducts….Floor or ceiling. It appears to be counterproductive to me to put the duct work in the ceiling since it will have so far to go. We are looking for the most cost effective, not upfront cost but operating cost, solution. In addition, we are considering DF heat pumps. The house will need 2 or 3 to be zoned correctly. Please let me know about the duct placement and thank you for your help? Continue reading “Duct Work and High Ceilings” »

The variable air volume box or VAV box is a commercial solution to adding multiple zones to large buildings. VAV boxes offer zoning solutions so that separate zoning demands or temperature selections can be maintained in different areas of the building. If the president of the company wants the temperature in their office to be 70 degrees Fahrenheit but the vice president wants their office to be 74 degrees Fahrenheit then it is possible with the VAV zoning system as long as their VAV boxes are on different zones. This particular VAV box in the picture is not fan powered. It relies on the main VAV air handling unit to provide all the air. Generally, when a fan powered VAV box is calling for heat the damper inside the VAV box closes down so that minimal CFM’s are coming through the primary duct from the

Heat is energy and when we produce heat we need to use energy in its production. There are natural methods for producing heat without burning or using fuels but these methods are not practical or available to the general populace for residential, commercial, and industrial use. The production heat, whether for residential, commercial, or industrial uses, uses energy and energy costs money. It is thereby necessary to have reliable and proven methods of measuring the amount of heat produced using a specific quantity of energy. Employing these reliable and proven methods we can also use the data to determine the best methods of producing heat for homes, businesses, and industry. 
15) We added a 300 sq.ft. of living space to our home as a sun porch. How do we effectively, efficiently heat/cool this space? We’ve been pitched several options. 1) Use existing with a manual duct damper to the new sun porch. 2) same as above but use a zoned approach w/auto dampers for main house 1st floor and sun porch plus separate thermostats. 3)
