Space Heating Rules of Thumb A Space Heating Capacities Well-insulated buildings Minimally insulated buildings It is recommended that at least two units be used for space heating applications. Multiple units add redundancy and also promote a more even heating distribution across the space. Natural winter infiltration rate is 0.10 to 0.20 ACH for tight buildings. Colder climates will tend to be at the higher end of these ranges. Proven Performance Typical Space Heating Application Greenheck’s space heating systems have heated millions of square feet of warehouses, distributions centers, and manufacturing...

System Analysis Greenheat® 100% Outdoor Air System The Greenheat 100% outdoor air systems provide maximum heating with maximum airflow. Air is supplied to the space at a high velocity and high discharge temperature (120-140°F). This unit cycles both the blower and direct-fired burner on a call for heat from a remote space thermostat. Utilizing 100% of the outdoor air positively pressurizes the space to offset the effects of cold air infiltration. This system is great for poorly insulated spaces with high infiltration rates such as warehouses and distribution centers. Greenheat® 50/50 Recirculation...
