Several weeks ago when running hot water in the tub, I noticed the
water was discolored...brownish like rust or sediment. The cold water
is clean. A friend suggested I drain the water heater. I turned off
the main water valve to the home, opened several hot water spigots
upstairs, and ran a hose from the drain fitting on the bottom side of
the hot water heater. Water from the hot water heater was drained and,
at times, a brown sediment was noted as the hot water heater drained. I
repeated the process at least six times over the course of three days.
I'm still getting discolored hot water.

I did note some rust forming around a joint in the line running to the
cold(water) recirculating loop connection. I did not note any leakage.

The Apollo Hot Water Heater provides potable hot water for the home and
also provides hot water through exchangers where air is blown over a
hot waterfilled coil...and the house is heated.

Is anyone familiar with this type of hot water heater? and does anyone
have a idea as to what is causing the discolored hot water.

One other question. Does anyone know of a dependable, competent
plumber/HVAC in the Cary/Apex, NC area?

This is a shot in the dark....

I have the same system in my house and I am going through the same issues.
Do you remember what your resolution was. I have flushed the hot water
heater out many times. I have installed filters and it appears the brown
sediment is coming out of the furnace. Any input you can give would be
helpful.

You need to flush the whole hot water system. The heat exchanger,
lines, - the whole enchalada. Wouldn't hurt to put a bit of phosphoric
or something through it too. Heating systems are generally "closed"
with a limitted amount of oxygen to oxidize the system. Your system is
an open system, with disolved oxygen in the make-up water.

Bad system when it comes down to it.
