DIY Heat Pump Water Heater. DIY. Home made mini split.

I am forced to do this because the USA does not sell mini split water heater other then sanden or now SANCO2 for like 5k which is a ripoff and it sucks. max output is 1400btu at 47f outside temperature. eff is 4.2 at 47f and 2.8 at 17f. my system blower the doors iff this one. my speed of recovery is 22000btu above 47f. Europe lives on mini split water heaters but USA refuses to sell them. daikin, fujitsu, mitsubishi and others sell them there. I even tried to get one from alibaba but they didn't want to send go the US saying taxes are too much. So I have to improvise as our forefathers did to build this country. Enjoy!

I will try to do a update after system is fully working at home. I'll try to do a detailed video on how is did thr coil for this who as interested.

this is a mockup so it will be done properly. this was done to see if I would get any error codes from the system. all is well so I can move on to finish the system.

the mini split is a LG la120hyv3
coil is 100ft 1/4 inch coiled inside the tank to be the same amount of tubing as is in the indoor evaporator lg designed.

no error codes. output is 150f return was 80f with 45f water and As the temp in the mid to top of tank got to 135 midway up and 147f on top. water started as well water. 40f. one hr of running the heat pump used 1200watts and heated 70gal of water to 145f. very high COP. probably 5/600%.

why I chose this lg model is because at 5f running full speed in heating mode it still runs at 310% efficiency. no other on the market does. not mitsubishi bot fujitsu not daikin. no one. only this model lg.

output is 24000btu above 47f and 14000btu at 5f. cop at full blast at 47f is 600% and at 5f its 310%. I live in cold climate so this will still heat twice as fast as a store bought heat pump water heater that takes the heat from your house. they heat at 6-7000btu. this works in worst case senerio at 5f outdoor temp will heat twice as fast as your store bought one and most of the year will heat 3 times as fast if store bought hpwh is in heatpump only mode not using electric resistance heat.

last step is to set up the coil in tank and secure it properly and weld the top back on to the water heat and inject some foam for insulation.
