Hey, Duke.
Spec lists temp adjustable from 140° to 200° - any plan to temper to 110° somehow? Or do you think it’ll cool enough by the time it spins off the wheels?
I’m also trying to figure out how a 1300-watt heating element uses less electricity than a 40-watt lightbulb.

If instead of using a 50 gallon water barrel, you used a 5 gallon bucket, you might be able to get by with a fish tank heater which would be way simplier and cheaper than the system you are proposing.

Duke as an HVAC guy, you know that dissolved minerals are attracted to hot surfaces, are the heating elements replaceable?

I suppose if you poured one cup of hot tea, at 8:00AM then just let it cycle on/off to keep 2 quarts at 140° it could possible be less that the 40w bulb on all day but even that is a stretch.

I put hot water in my 5 gallon bucket with the submersible pump that came with my Cab King. By the time the 5 gallons runs out or the water cools off, it's time to quit grinding for the day.

I like pumps systems that recirculate water. I have a one gallon rubbermaid bowl with a handle. I fill it with hot water from the tap add coolant and pour into a tray. It is kind of a jump start on a colder day. I don't change water until I go from grinding to sanding.

They are All very good questions, I will need to investigate further and may add another type of heater and just dump the water in a open top bucket with a float switch to keep water in the bucket to the desired level and use the pump just to recirculate water through heater then back into bucket. As far as minerals Go I have a KICK ASS Reverse Osmosis System I built a Few Years Ago That I use to wash My 38 Solar Panels with. I have about 55 gals of water stored up with a float system and a Pump That I have that runs underground to them. Naturally in the winter time it is non operational. I ac have a couple Barrels filled with RO Water in my garage ahead of time and just take a hose when empty and start my RO system being it is located in my house. But lets get real here by the time that system gets all corroded up ill be dead anyways! No doubt I have some figuring to do, now that I have run these Ideas past my SKUNK WORK SCIENTIST Dept. ~Duke

TheRock Thanks for keeping an open mind to the feedback you're getting - I'm all about simplicity and I definitely don't mean this as a 'you should' just simply showing you what I built for delivering recirculated warm water to my wheels. I rebuilt it once a couple of years ago to go to a larger glass aquarium - and I upgraded the water pump once - but for the most part this system has been running uninterrupted and flawlessly for the better part of five years. The best part is as of lately, many months go by at times when I haven't used my wheels and the water system doesn't care - it's operating exactly like a fish tank would with a flow and return designed to last years and years and not fail and kill fish. My garage stays pretty cool in the summer so even evaporation has not been an issue. The operation in a nutshell is - 30 gallon glass aquarium on the bottom shelf of the workbench my grinders sit on. Water is pumped with an impeller motor up to a 2" PVC manifold then back into the main chamber of the tank. When the flow valve is closed, water is forced into the small feed lines that go to the grinders and are controlled by a needle valve at the wheels. During winter months the temperature is kept at a steady 82 degrees with a 75w submersible aquarium heater. Waste water is returned to the system separately and has to go through two chambers of fiber fill (one $5 Walmart pillow a year) before rejoining the main tank. [Edited to add] I Forgot to mention that I have a bypass system on the 4-wheel "dirty" grinder - when I know I'm going to be shaping a material that is either toxic or very muddy I divert the grinder drain hose into a bucket and let it settle before disposing of it separately. When this causes the tank water level to drop I just fill it back up to normal range with clean water. Hope this makes sense -

I use an empty gallon oil container for my winter water, fill it up inside with hot water and gravity feed to the grinder. Duke look at trying to stop the tornado that whips around the rotating wheels, that really is the main cause of cold hands, even with hot water. I built the guards of my machine with a gap down the bottom at the back, most of the tornado just blows straight out the back and not around and around on my hands.

Now you have me wondering what the heating element looks like in the water heater in my trailer? We replaced it once, but that was a few years ago...

TheRock Oh dear, my mistake sir. I wasn’t seeing your diagram correctly, I thought you had the drain piped back to the 55 gal drum!! All good if using water single pass.
