in cold weather I turn the heater on. At first it is warm , but then cools off.
When I shut the heater off for a bit and then turn it back on, it blows hot air for a while, but the cool air returns.
Last year I had a new water pumpt put in, a new thermostat and I had the system backed flushed.
What could be causing the problem?
