HVAC Energy Conservation

Welcome to Energy Conservation toward reducing your heating & air conditioning costs & to ask all kinds of questions.Feel free to post about anything related to HVAC and/or Energy Conservation.There are many areas where your air conditioner or heat pump may be losing efficiency, together we can achieve optimal efficiency of operation.This is valuable free information being offered to you so you can save on your energy usage costs, & practice Energy Conservation for America.

The design of the some OIL furnaces’ with their ultra large heat exchanger coming to near the top of the furnace and the blower set to the side at the bottom of the furnace, can be an engineered airflow problem. The blower set to the side blows against the heat exchanger and the back of the furnace which blocks directional airflow velocity thus generating high initial velocity & static back pressures against the blower.Most installers set the A-Coil directly on top of an oil furnace with no transitions resulting in another restriction, between the huge HEAT-Exchanger resulting in blocking of directional velocity airflow, killing velocity flow & causing a huge leap in (ESP) static pressure.A Major “Oil Furnace” Airflow Problem FixRegal & Hallmark & nearly all Oil Furnaces - Installation manuals: http://www.boyertownfurnace.com/ProductDocuments/index.aspxDownload the installation & service manuals:  http://www.boyertownfurnace.com/ProductDocuments/HallmarkONLYManual042909.pdf 
If the oil furnace is used in connection with summer air conditioning the evaporator coil must be installed at least 6” above the oil furnace for proper airflow. Distances less than 6” will result in decreased airflow. Make sure outlet supply takeoffs are NOT blocked by the coil. In all cases, refer to the manufacturers’ data for static pressure losses to ensure the total system static pressure does not exceed 0.5” WC.

SW WI Tri state area, MOLO Plumbing & Heating sets the A-Coil at least 6″ above a Thermo Pride OL 11 oil furnace. They know the importance of unrestricted airflow!http://www.molocompanies.com/plumbingandheating/index.html
