hydro hot solution

(1/3) > >>

Roger Baldwin:
Our hydro hot is not working well and we checked and saw the solution tank is empty. We have shut it down.  We did not have a warning of any kind.  We need to refill this tank but our manual only says it is a solution of antifreeze and water, but not the dilution amount.  Is this standard antifreeze and is it a 50/50 mix?  Heating with electric heaters for now.  Also, looks difficult to fill because of the proximity to the top, but we have an antifreeze hand pump that should work. Model # HHE 500-04M. Also, Gerald, do you know if any certified techs will be at the Rally in Albuquerque at American RV?  We probably need a tune up and would like to call now and make an appt. because they are so busy during the rallies.

Thanks,

Thanks Gerald, do you know the dilution rate and what kind of antifreeze we could put in the overflow for now?

Gerald Farris:
Aqua-Hot changed to non-toxic coolant on their units to prevent dangerous contamination of drinking water in case of a leak in a heat exchanger, but I am not sure when the change was made. I think that Aqua-Hot recommends propylene glycol-based, boiler-type antifreeze in all of their units, but I am not positive, since I have a Hurricane heater, and seldom work on Aqua-Hot units.

 Orman may be of more help here.
