RE: Water Temp. Problem

[Theo Smit <theo.smit@dynastream.com>]

If the thermostat was stuck, then you'd still get hot air out of the
heater, since heater circulation isn't dependent on the thermostat. It
sounds more like a clogged bypass hose, as described by Bob, where there
is no water flow to speak of until the thermostat opens.
