Hey all,
Wanted to let you know that @tronsington and I have received two unique M64 based boilers to test. The RY3T mini, thanks to Christian at RY3T. And the HS05, courtesy of PG at Heat Core.
These units will be installed into a radiant floor system at The Space. We’ll make sure to document our process and findings here.
Let us know if you have any specific questions!
What are the pecs of the power input in those cabinets?
Would be a bit counterintuitive if they require 3-phase, given that the M64 is specifically built for single-phase home use.
same question here i would be wondering how the singe phase is managed by RY3T mini. Two input Cables? Should not be 3 Phase correct? I mean the M64 was probably for a reason designed to be singe Phase.
I’ll have to go look up the exact connector type. But it seems to be a normal 30 Amp plug for single phase, 220 V.
Radiant install in progress. 1/2" PEX. Will do 5 zones across the two first floor sides of our building. As close to 300 ft runs as possible. Using the aluminum heat transfer plates to spread the heat out across the sub floor boards.
30 Amp, 220 V. Same for each unit. We wired them up with a standard L6-30 receptacle.
Both the RY3T Mini and Heatcore HS05 units have PDUs built in to the boiler. Single power cable into the boiler. Then a connector sends power to the M64 miner. I’ll start a unique thread for the RY3T Mini and HS05 respectively so we can organize information. I’ll keep this thread dedicated to our Radiant floor demo site at The Space.
The Exergy radiant floor install at our office in The Space is finally complete.
This took a bit longer than expected to be completed. We ended up hiring professionals to help us complete the job in a timely manner.
The plumbers did good work with the wall portion of the loop. There were a few pain points that required fixing, however:
Also, we ended up needing 6 zones.
System is up and running. We tested out the heated floors for the first time yesterday. Here are my initial reactions.
Came back in this morning after letting the system run overnight and I’m pretty sure we have an air lock in zone 5 and 6. No flow. Bubbles in the flow meter. Will troubleshoot today!
Radiator installed out back so we can choose to heat the floors or dump heat outside in the summer. We have 20kW of solar on the building, so this lets us mine full time.
Your setup looks sooo good!! Is there control functionality to ramp up and down or do you have to dump heat to the radiator if the floors reject it?
We are building the logic to “step” up and down in wattage with the default high, medium, low settings on the whatsminer firmware. But We’d prefer to control exact wattage. That elusive firmware problem looms over us (Whatsminer M64 Firmware - Dynamic Power Adjustment?)
So most likely a mix of step changes and bang-bang. Still in development.
Any recommendations on a heat exchanger if I want to use a similar setup to heat a pool?
Pools would need a titanium heat exchanger. They usually come in “tube and shell” style. Not sure on sizing, that would depend on a lot of factors. @Exergy might have the math chops to sort that out.
