HYDRO HOT FLUID LEVEL CUTOFF SWITCH

(1/3) > >>

George Harwell:
The hydro hot in my coach is eating the low fluid cutoff switches 1 per year. The original lasted 4 years and the last 2 have failed in 11 months. Had to go outside this morning to disconnect the switch leads and install a jumper to have hot water and heat. I talked with factory last year and they indicated I may have gotten a defective part but would not stand behind it. Just offered to sell me another unit.I'm considering leaving the jumper in place and checking the overflow tank every morning. Can't believe they haven't solved this problem. Heck of a way to start out 2010!

HYDRO HOT HHE-500-07m

Joel Ashley:
So the last 2 replacement switches weren't warrantied?  (Electrical parts often are only 90 days, if that)  Even if not warrantied, AquaHot should have seen a red flag, given their switches aren't lasting a year.  With demand for coaches down in this economy, they should be alert to any ongoing problem that might besmirch their reputation, and with fewer units to build they should have time to research fixes.  It would be nice if they at least asked you to send them the failed switch(es) for testing and examination.

Gerald Farris:
The idea of operating your Hydro-Hot system with the low fluid level sensor by-passed can cause some very expensive problems. As a short term emergency repair (if you are sure that the system is not low on fluid) it is OK. But if left in place, and a bad leak developes while the system is running the burner chamber can overheat and cause major damage.

Bruce Benson:
Hopefully you would notice a leak when it occurs.  Ours, a model AHE-100-01S was not built with a fluid level switch, so we take that chance everyday of operation.  The fluid level switch appears to be an addition added to later models due, I am sure, to problems eluded to by Gerald.

I agree that Aqua Hot needs to be a little more responsive.  I just had to have one but can honestly say that it is the most troublesome system in the coach.  I thought it would be quieter than the forced air but in our old coach it is not.  

I does provide a little better BTU for the dollar but I question how much of that is lost through the plumbing.  The heat exchangers on my coach are difficult to clean and noisy.  Admitting that I never had a forced air system this old I do remember the forced air as being trouble free.  The hot water is nice but a little management can make a 10 gal hot water heater work fine for us.  No, I would not go out of my way to buy another one.

George Harwell:
After further research I have determined that I am the victim of lowest bidder syndrom. I found a fellow BEAVER owner 02 Contessa with the same model Hydro Hot and his float switch is of a different design and color and is the original that came in the unit, No problems with it. I suspect the company (VEHICLE SYSTEMS INC. at the time) found a lower bidder and the product most likely came from China. I appreciate the responses and am well aware of the potential for disaster if a leak were to occur. I am also well aware that it is 32 degrees here in Florida and I'm not into cold showers.

WAITING FOR WARMER WEATHER!
