How many zones does your boiler have? It sounds like you have just 1
zone. If thats the case you would have to zone off the downstairs
seperately by adding on a circulator pump or a solenoid valve after you
isolated off the basement pipes. You also need a thermostat and a
control box. Could you give us a little more info?

As far as I know, the boiler only has one zone. I was hoping that some
sort of three-way solenoid valve would do the trick (upstairs open,
downstairs open, both open) but I haven't been able to find any info on
that. Would I need a valve on both the supply and return lines? What
sort of control box would I need.

First you would need to isolate the basement zone from the upstairs by
redoing the plumbing. Next you have either 1 of 2 choices. Get the
solenoid valves and put them on each zone. Or get an extra circulator
pump and put it on the basement zone. You will also need a control box
to interface the basement thermostat to the new circulator pump.
You don't need valves on both supply and return sides. Just on the
supply side.

Cheapest would be more radiators in the basement. Is it baseboard, or a
mix of the two, between upstairs and down stairs. Large cast iron will
get you the most BTU. This is what happens when you don`t have a pro
do a load calculation and you are guessing. Best would be excess
capacity and a valve to allow you to manualy reduce flow-heat. Do your
floors have or will floor have carpet, that and foam padding will help a
little.

Yes, sort of. They may be plenty big enough if they were on an separate
zone. Is it ossilbe to damper down the upstsairs heaters to force it to
take longer to heat totaly? Not as good as a zone, but a cheap solution.

Yes. Can be done. This is the best way to handle situations like that.
