    question about re-circulated water units

    How long should it take before you should start to feel the heat from a 4 pipe re-circulated water unit in a condo? I should add that the cool setting was on for about 2 hours before switching over to heat mode.

    Should be just a couple of minutes ... assuming they have the boiler on.

    Are you sure it's not a 3 pipe system? A 4 pipe should only take a few minutes whereas a 3 pipe could take much, much longer depending on overall demand.
