Default Recommendations for a tankless water heater

Hi, I do large batches (avg 20 gallons) and want to filter water through a tankless water heater that can provide on demand hot water (160 degrees) for mashing and hlt to shorten my brew day and hopefully double batch. Anyone have any suggestions for me? This will be dedicated for brewing in the garage.


Thanks!

Seriously you are looking for a 100 degree lift above ground water that is 1 very powerful heater

The biggest rheem makes the RTE 27 takes 112 amps at 240 volts to produce a 100 degree lift at 1.84 gallons per minute.

Scroll to the bottom of this page. Not sure what's been modified, but 3gpm at 170* sounds good to me.

Is he looking for gas or electric is the question. A 200,000 but or so gas fied tankless heater will make 5 GPM at 70 degree rise. I'd think you would be able to get a good flow at 100 degree delta t. You would need a commercial model to allow an output that high.

But most homes do not have a big enough gas line

I have normal house gas line and a 240v 50A circuit so either gas or electric. I've looked at several models, just looking for some advice before I plunk down 1K + on a heater. Heating 60 degree ground water now takes a long time with my propane rig so anything would be an improvement. An endless flow of 160 degree water would allow me to go nuts on brew day with back to back brews and cleanup.... I'm totally open to either gas or electric and looking to see if anyone has any experience with brewing with these. Thanks!

People on the site have made rims tubes that were able to heat sparge water to 170. That would probably be a lot cheaper option than a commercial tankless.
