Sure and with forced air you can run your blower 24x7. Ive lived with HW
for years and run an aquastat. I dought a 100w pump will do it mine is
apx 225 watt. it all adds up, for me running 225watts 24x7 adds apx 30$
a month. If you want to do it then be sure to correctly find out the
btu of what you have, it will take research, don`t guess. Then oversize
the baseboard and use valves to throttle it down if it is to hot .
Another consideration is boiler temp, although you say you are set at
170 my boiler never reaches 170 till apx 0f outside. Otherwise 140-155
is all it reaches. Some Baseboards are designed for 170-190 you need to
know btu output at low temps, Large cast iron start putting out heat at
apx 85f. Im guessing but Id look into also water capacity and mass in
Lbs. of both to help in matching. I would be sure if I were doing it to
oversize output and have a valve you can cut back water to only that
room , non others on that run-takeoff. If you research it well and can
cut that room down it will work. " The Wal l" is a good group you will
get alot of boiler pros at, and answers, unlike alt. Hvac "hacks"
