ok, today i went out and played with the aquahot.
i took the access panels off of the various units inside.
the first one i did was the one under the kitchen counter. it is easy to get at and one of the two computer fans on the back of the unit was not working. the unit in the bedroom and the one in the rear bath are identical to the one in the kitchen. all 3 are a heat exchanger with two 92x25mm computer fans that have 46cfm, 2.9w and 2900 rpm each with ball bearings each.
the one in the living room has nothing other than hoses coming from the plenum below. one of the two hoses was mostly off so i wasnt getting the best airflow. so i sealed both of them and put them back on. only the HI speed switch setting gives any airflow out of them.
what i have not figured out yet is where the "extra" hose goes that is blowing hot air somewhere that is under that cabinet with the two that come out in the living room.
i am looking for replacement computer fans that have similar specs and have not found them yet. the particular fans that are on it i have not found in the usa yet.
the fan in the midbath is a heatexchanger with a single bigger computer fan on it. it makes a ton of noise and i need to replace it. unfortunately, they riveted the fan on the housing rather than using screws like the other ones. it is under the sink and pretty close quarters. i will have to take the complete heat exchanger out to change it. it is a bigger unit and seems to be a 120mm fan.
i think they all need to be ball bearing fans in that they seem to have higher temperature ratings they can operate at for sustained periods of time.
