EU Comfort number (1-4 stars)

Of course I'd hack a brand new device, wouldn't be the first time. The trick is don't do anything detectable to the original device until after the warranty expires, if ever.

As for Legionaries, seems there's around 40 variations that cause various problems including pneumonia showing up with no apparent cause. Below 55 F it's killed by other things in the water. Above 130F it's killed by long term heat. Short blasts of hot water doesn't touch it, nor does chlorine.

It loves rust.

But apparently it has trouble with flowing water so something like the water pipes coming from the street main or through an on-demand heater are ok. Small amounts but not enough to bother people.

Tank type water heaters can build it up in the bottom and hydronic heating systems during summer idle times. As far as I know all hydronic systems have to be isolated from potable water by check valves, pressure difference, and heat exchangers. This new heater has all 3 built in. The heating loop only runs at 1-2 bar.

Boiler mostly installed. The system has since been tested at pressure and heat (yesterday).
