it also increases winter indoor humidity. a house that needs a humidifier
in wintertime is probably too air-leaky.
a window exhaust fan might help you find leaks, and you might measure
air-sealing progress (and find which leaks to fix next) with testo's $150
405 v2 "velocity stick," a durable hot-wire anemometer that measures
airflow from 0 to 2000 fpm down to 0 fpm with 1 fpm resolution and 20 fpm
accuracy on the 0-400 fpm scale, and also measures temperature from -20
to 160 f with 0.5 f accuracy and 0.1 f resolution. testo (nj) is at
(800) 227-0729 or www.testo.de/us/en. crack open a window and put the
stick in the crack and measure the air velocity with the fan running.
as you seal up the house, the air velocity will increase.

vertical thermosyphoning air heaters below the windows with david delaney's
"flow organiser" near the top...

what was your solution? i like the idea of thermal mass in the ceiling,
(as in "the barra system") where it can supply some radiant heat and be
warmer than the room (storing more heat than room temp mass) and allow
night setbacks. a room air thermostat and slow ceiling fan can control
the room temp.
