My flash boiler can take it from 50* to boil at about 1/2 gal per minute and cost me about $60 to build. Works great for me and I also use it to mashout on 1bbl batches.

The devil is in the details of course... If you flow it at .3 GPM, it will shut off. It turns back on at .4GPM. It's too fast. I also can't find if there is a max temp or selectable temp range. I don't think they'd let it get over 140F for safety.
FWIW, My house is using a tankless (Bosch) and they have safety features to prevent scalding. I dont know if you'd be able to override those, but the thermostat for my unit does not go above 128F

That's what I was thinking about before I built the flash boiler. I was not sure if they could get hot enough of if the parts inside were rated for anything that hot.

I was thinking the same thing today, but instead of feeding cold water, feeding in water from my hot-water tank at about 130F. Can a smaller wattage tankless raise this to 170F? I've been looking at specs for models by Bosch and I can't seem to find the maximum operating temp.
I have on demand hot sparge water from my RIMS tube... it was pretty cheap and easy to do. My new rig that is in process will have the same, no wasting energy keeping a pot of hot water around. Just heat it when needed at the point of use. I figure, I already have a RIMS, why not use it for mash and sparge?? I can get .7gal/min. from 60-165F which is plenty for a fly sparge.

I'm not familiar with electric, as I prefer fire, however I have a tankless gas water heater in the house. Mine is adjustable and will go up to 170 before a safety shutoff occurs. This thread has me tempted to remove it and take it with me for brewing and throw a cheap tank model in the house. I would need a natural gas hookup. Adjusted right and with the outflow closer than my shower the tankless could definitely work. Don't forget about fire.
