mike have you done any reaserch on this yet
there are alot of exotic systems out on the market today but dont rule out oil . Oil is got a bad rap but the efficiency is way up there now .
electric is good for on demand heat but a killer on price for heating forced hot air is a good heat source but pros and cons there with dry air a good humidifier installed works wonders on it
what is nice about forced hot water /base board heat is you can zone it out to different parts of the house and heat the areas you use the most as with other types of heat you can do this too
but baseboard is more effective at this and easier to maintian I have a 6500 square foot house with a 85 % efficient boiler baseboard heat and it cost me around 550 dollars a year including hot water i live in massachusetts
the best thing to do is have a heating consultant do a heat load on your house for your area and give you quotes on the systems for you
they would know better.
