I think kstills is correct when he writes that my heat loss is likely outmatching boiler output. just for the hell of it, I put the upstairs on it's own zone and turned down the heat up there, and the boiler was easily able to get the downstairs house temp to 72*. I can live with a colder upstairs, but now the switching relay for the upstairs zone is dead, so I am back to where I started with the downstairs at 66* until I get the chance to buy another. I have noticed that the baseboards upstairs get warmer than the ones downstairs, which is confusing to me.
Part concern, part obsession.
Some things you can do immediately to help out the situation of heat loss that don't cost a ton of money:
1) bubble wrap for your windows. http://www.staples.com/Staples-Large-Bu ... uct_929853
Rolls are better, but using this will effectively double the insulation value of a single pane window, huge in terms of change in heat loss.
2). Fill cellar windows with insulation.
I used fiberglass batt stapled to a fitted board and stuffed it into the window wells.
3.) Insulation on your pipework.
Fitted foam insulation at Home Depot is ~1.50 for three feet, less if bought in bulk, will stop you from heating the basement and direct more heat upstairs.
4) spray foam insulation into any hole to the outside (cellar) or from one floor to another.
Cans are fairly cheap, but use it all up in one go as the nozzle clogs with the goop and it's hard to reuse.
Of course, any insulation added to the attic is a huge factor in reducing heat loss.
Aren't your zones independently valved? Sounds like you have less resistance to flow going upstairs, so if you have a valve in line throttle it back a good bit and see if that helps.
Good news is, after this week it looks like the weather begins to moderate and you shouldn't have any more low temps to deal with.
