Envirofan Heating



The effectiveness of an Envirofan system for winter heating is based on the simple concept of heat stratification. That is, within a closed space heavier cold air drops to floor level while lighter warm air rises to the ceiling. As a result the air temperature can increase about 3/4 degree per foot from floor level to the ceiling. This difference can be even greater when there is production process heat or bright lighting in the room.

Consider a room with a 15' ceiling and with no fans. The temperature might be set at 68 degrees at thermostat level (5' above the floor), but would be only 64 degrees at floor level and 76 degrees at the ceiling. The people and floor levels would be cold and drafty and the ceiling level would be hot and stuffy. The thermostat would then be turned up higher than 68 degrees to maintain actual 68 degree comfort at people level. It would keep asking for more heat, even though the ceiling was already filled with wasted inaccessible heat.

Envirofans equalize room temperature by pushing down and mixing wasted ceiling heat with the cooler air below. The thermostat stays satisfied for longer periods of time and can be set at the actual desired temperature level. People will be more comfortable and productive. In high ceiling areas like warehouses, thermostats can be cut 5-10 degrees after installing an Envirofan system, yet floor temperatures will still increase.

Best of all, statistics from the utility industry show that the resulting savings in heating costs can be as high as 30%. For every degree the ceiling temperature is lowered by destratifying heat with ceiling fans there can be a 3% savings in energy costs. With energy savings like that an Envirofan system can pay for itself in the first year!

It takes a high quality, powerful industrial motor and efficient blade design to create enough air movement for results like these . . . it takes ENVIROFAN!
