WON heaters junk?

[cvonseggern]

I've had the thermostats on two different WON titanium heaters fail in the last week. Both stuck "on" and were continuously heating, even with the temp probes in a bowl of cold tapwater. Neither heater was more than about 8 months old...I can't figure out what's going on. I was led to believe that this was a good heater brand. Was I misled?

Can't comment on quality of WON heaters, but ... do you really need a heater? I have never run a heater in a SW system, "warming" the water has never been an issue.

You said you put the probe in cold water? You might want to re-think that as a test. Warm/hot water should make the heater turn off.

I had the heaters fail also when I used them, but yes, you want to put them in hot water to see if they turn off.

Yeah, just had a short-circuit in the brain there. They were both heating the water with temp turned all the way down and tank water at 82 degrees...I'm going to go test them with hot water

Sure enough, with my brain working right the thermostats on both are out of whack. A little bench-testing with a thermometer and cups of warm water showed neither will go below 87-88 degrees, even with the dial turned all the way down. I'm really disappointed in this brand and won't buy it again. I spent some extra money on these to avoid just this problem.

The only reason I have heaters in the first place is to provide stability when the house temp drops. Turns out I might well be better off without them.

I use a Won, its the one with the remote thermostat, not the one with the temp probe, never had a problem, however, the iones wth the probe have been guily of wiping out many a tank for the exact reason you describe. Search RC, youll see what mean. Those things are junk... IMO.

Has anybody had any bad experiences with ViaAqua titanium heaters? The one I have has a probe and a remote thermostat control. It looks like it is solid state. I thought it would be safe. It may not be solid state though. I'm just guessing.
