Have an immediate need to replace a gas furnace which is serving radiators in a 110 year old, 2200 square foot (heating area) home in Toronto, Canada. As we renovate we will add 1500 square feet and convert to either radiant floors or baseboards. (Average winter temperature 32F).
Is there any difference (other than BTU ratings) between what I will need now versus later to accommodate baseboard or radiant heaters?
Can anyone recommend any brand of furnace that they have had success with ?
Does anyone know of an instant / tankless hot water heater system that can be set up to provide both hot water for showers and for heating ?

Different radiator types take different boiler settings, so be sure the addition specs are appropriate.
BTW, you don'tr need a furnace at all. You need a boiler.

*take this to http://www.heatinghelp.com and post it on "the wall".you will have to watch it every 6 0r 12 hours though, because they have no archive and if the site is real active you'll miss the answers.they know more about steam and hot water heat than anyone anywhere else!
*Gavin -Here are a few suggestions:There are 90+ efficient boilers now - more expensive up front but cheaper to operate. Check into a secondary unfired boiler/heat exchanger for domestic hot water. New electronic controls allow use of one boiler for different heat methods all at once with either modulating valves or variable speed injection pumps. Baseboards require hot(160F) water, radiant is warm(115F) and DHW can be set to have priority operation over other two. The house needs to have a heat load calculation done both for current size and for enlarged size - check with your heating contractor for alternatives. Good luck!
*Any specific product suggestions, Steve? Our temperatures are pretty close to yours, except we usually get some moderation from Lake Ontario and less snow than you !
*Thanks Bob, for pointing out such an obvious error. Are there any specific products / manufacturers you have had success with ?And any suggestions for how I should calculate my capacity requirements ?
