I LOVE hydronic heat!
Is your system hot water, or steam? What kind of radiators do you have, baseboard, cast iron, radiant floors? These things are awesome and tend to work for a good long time.
Who needs a dryer when you can just drape things over a radiator? (Answer: Everyone needs a dryer, you don't want the washer to get lonely.)
I am trying to move to Boston, if I can find a job. Hydronic heating is way more common in New England than it is in DC, and I can't wait to get there.
Keep warm,
Dave
