The only problem is that it is very slow to respond, so that most users
simply leave it on all the time. For people who need heat for only a
couple of hours per day, say in the morning before leaving for work, it
probably is not as energy efficient as a conventional system with a
programmable thermostat. I'm using it for a child care center, which I
think is nearly an ideal application. BTW, it seems to be cost competitive
with conventional package HVAC units, although of course you do not get
mechanical ventilation and AC.
