My house was built in 2001. We moved in in 3/01. We have a gas-fired Lochinvar boiler (300KBtu) with Hydro-Air.
The circuit has a Primary circulating pump, and then 4 other pumps (1 for the 1st floor Hydro-air, 1 for the 2nd floor Hydro-air, 1 for the indirect hot water heater, and 1 for the radiant floor in the master bath).
Since the floor in the master bath runs 24 hrs/day, the primary circulating pump runs the same amount of time.
We just had someone to the house because we have no heat/hot water. The main (primary) pump is burned out. this is the 3rd time this has happened. It burns out about once a year. Has anyone heard of this? This seems ridiculous to me.
