I would like to know if this is normal for a hydro-hot system or if this particular system is cursed
it is a coach I am looking at for possible purchase.
Between 2008 and 2015 (I don't have dates for all the repairs as the receipts are not all date) the following occurred:
Electric heating element replaced (7/2012)
Float switch, high limit switch, O-ring, blower motor- $1234
Fuel nozzle, photo disc, electrodes, grommets, PC control board, 12 volt control unit, combustion chamber (warranted)- $2476
Stir pump replacement retrofit kit, mixing valve tempering 145 degree-$822
I just have parts numbers for the next one- "no heating zone 1"-$349.35
Replace zone pump (part warranted)-$372
Inoperative, "problem between panel and heater"- $523
Circulation pump, incorrect wiring (this was 12/07)-$426
Bedroom hydro-hot switch stays on, never goes off- problem not found 5/08
That is all I have records for, don't know that every record was saved
Total repair costs over this 7 year period were at least the $6200 listed above...is it really $1000/ year (roughly, as maintenance is not included, yet I assume needed) to keep a hydro-hot system going or is this beyond normal?
Thanks
