kiln venting = heat loss??

Sorry if this is a stupid question folks. I have an electric kiln which I
fire to cone 6. I vent it with a hood. My question is this: some sort of
flow through ventilation seems to be preferred. With an electric kiln
would I not be losing a lot of the heat by circulating outside air
throught he kiln? Would this not increase my firing time a lot?

Thanks,
Ian
