Most gas furnaces in the US are forced air distribution just like the

Here in New England water is still used a lot. I have baseboard and it
does an excellent job providing even heat and no noise. Central AC is
not as popular here as in warmer climates.

Another reason is fuel. Oil is still the most used and works best with
water. Electric, either resistance or heat pump is very expensive here
with the highest rates in the country.
Oil Forced Air was the "standard" for North American central heat
for decades. A LOT less problems than hydronics - and if the power
goes out and it gets cold Hydronics can get REAL EXPENSIVE, and REAL
FAST!!!!!

There is nothing simpler for central heat than forced air - whether
gas,(natural or propane), oil, or wood fired. Electric is just as
simple, but HELLISHLY EXPENSIVE - particularly here in Ontario.
