Well this is my take on these 3 idea's
Baseboard is the least expensive but you lose wall space where it or they are installed, they take a while to heat the rooAm up and are expensive to run
In floor heating is the most expensive to buy out of the 3 and the proper thermostat is very expensive, it is real nice on the toes though

Forced air units are small, inexpensive but more than baseboard, heats the room up fast and the lose of space in minimal. A 2000 watt will more than do the job for 170 sqft
