I thought about that and it is still an option, for that to be viable though I'd need to add casters on my brewstand (it's wheelbarrow style now) to haul it outside as there is no way I could move it with two full 26 gallon kettles on top with a rims setup. I like the concept though. I would also need a BCS or timer to kick it off early enough with pumps to get it to temp by the time I wanted to brew.

I have a Bosch tankless water heater that runs on gas. I have the flush kit installed in the bottom so I can run a hose from a tap through a carbon filter to the inlet side. I then run a food grade vinyl reinforced hose from the outlet side to my brew kettle. I have endless hot water that way. The only drawback is the highest I can set my heater is 140* and I wasn't able to find a household size heater that would do more than that. But 140* water instead of 55* water shortened my brew day quite a bit.

That's exactly the sort of feedback I'm looking for, would you mind sharing the model number?

I second Marcb's request. I am looking to do something similar.

Did you install the flush kit & hose outlet yourself? What does that look like?

I rent and old victorian in San Francisco. Wiring is shot so I can't use heating elements above 1,500w. Looking to use my already installed nat. gas tankless to speed things up.

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!
I visited Yakima Craft Brewing company and I know they were using a tankless water heater for their brewing water, and it was coming out at the 170 range.

You could try contacting them to see what kind of rig they have. They are doing like 3bbl batches at least a couple of years ago they were when I was there.

My sister has a commercial Rinnai model (propane) that does a heck of a job for her home AND her honey extracting facility. I'll check the model # next time I'm up there. I thing you change the output temp with jumpers...so that could be a pain.

I've looked in to this fairly extensively regrading Rinnai heaters. I have a RL75 natural gas unit. It requires a dedicated 3/4" water line input and a 3/4" dedicated gas connection, plus a 20A 120VAC connection.

The residential controllers will limit you to 140F, but you can get a commercial controller for these units and get 165-185F water depending on the unit. for my unit the RL75 my max water temp is 165. with the RL94 I believe you can get water out at 185

My BIG disclaimer, is that it is really easy to forget you have the water heater cranked up past 140, which can result in very bad burns if your SWMBO decides to take a shower when you are brewing.

That is an awesome idea, we are building a home and it comes with a Rinnai tankless water heater so I am finding out what model it is and see what I can do. Most likely it is the lowest one by them being "contractor grade" but we'll see

I found this propane powered tankless hot water for $200 and ordered it. It's normally $280 so I couldn't resist.

Here is the manufacturer's website.

It looks like you need this extra part to get over 140, but it was only $10

Hopefully it will come before the weekend and I can do some testing and report back. I don't expect to be able to sparge directly from it, but it should at least be able to give my HLT a big head start.
