Sphere Water Heater Large for home

[panyuming]

i also have plans to build a large heater using a 1 metre diameter sphere. that should be able to heat a house with very little or no power input.

Thanks for sharing!
I believe you succeeded in heating the ball, successful OU, so you will make a bigger one.
Thank you!

If the ball contains water is 1.7 gallons, it may be 6.44 (or 7.72) liters.
If the ball is full of water, it may be 14 liters.
In the video, the water temperature in the ball rises by 46 degrees Celsius (184F-101F) over a period of 2 minutes.
The current of the 9V battery = 0.18A, the power = 1.62W.

Conventional heating of 6.44 liters of water and raising it by 46 degrees Celsius requires a continuous input of 10.1kW in 2 minutes.

Duh. I shared that EXACT same calculation here years ago.

Thanks for sharing! Very encouraging data. Apparently an OU device.

You're welcome. Encouraging data indeed. No doubt it's an OU device.
