I know this is a new option but has anyone any info on the concern I have expressed. Also how is the noise level when the blower is activated.
The sales person is full of it. I saw a demonstration of it up in Prescott last Spring and it put out water hot enough to scald you while being pumped through an Oxygentics shower head. When the flow was adjusted to enough to take a shower, it was still hotter than I cared for.
One problem with the Girard is, in order to cut costs so the price could be kept significantly lower than it's closest competitor, the RV 500, they used only bare bones control componentry (this doesn't mean low quality). Because of that, usage is different from a conventional water heater. Temperature contol is achieved by regulating the flow of the water instead of blending it with cold water; the faster the flow, the lower the temperature. Many people don't understand this, use it incorrectly, then they assume the unit is no good. Also, many people have trouble getting it to work correctly because of flow restrictors in the plumbing. Using it is a completely different ball of wax but if one can adjust to it, it will do just fine.
I don't recall any blower noise from the demo unit (we were outdoors) so it's probably not any worse than a conventional water heater.
Being an old dog, I prefer staying with something I'm used to and would prefer the RV 500 even though it cost almost twice as much. But then, that's me. Your mileage may vary.
