Default Tankless Waterheater?

Anyone use a tankless water heater instead of a HLT? I was thinking it might work. Set the temp on the highest setting and use a PID or BCS to turn it off and on.

Pull fresh water through it to get the proper strike temp then use a valve to bring in the wort (using a pump) to recirculate through the tankless heater and back to the mash tun.

It seems like it would sort of be a RIMs system, but one you used to heat the strike water as well. I am assuming if the flow rate was high enough you would avoid scorching of the wort.

The hottest my tankless gets is 140. Not sure how that would work for an HLT without some extra massage.

You can get tankless water heaters that hit 180. You wouldn't want another controller. They have an integral controller that works pretty damn good. There are people that do this. I visited a 3BBL Nonabrewery that did this exact thing for strike water.

Here's some related threads:
