Circulating fan shouldn’t result in heat loss
Q. Our split-level home is heated by gas-fired hot water baseboards. Our central air conditioning system, which includes an electric air purifier, is on a separate duct system in the ceiling.
Do we experience an appreciable heat loss in the winter months when both the heat and air circulation fan are operating at the same time? My wife has allergies which are aided by the air purifier.
A. You shouldn’t experience any heat loss using the fan. If all windows and doors are closed, your house in a closed vessel. Using the fan to purify the air simply recirculates the heated air and equalizes temperature throughout the house.
The only possible negative effect (for lack of a better word) is that it may defeat the different temperatures you may want in separate areas of the house if your hydronic heating system has several zones and you set them at different temperatures.by
