So a few years ago, I bought an old broken down hot tub for $300 and restored it to working order. This took me about 2 months since all the frame wood was rotten and all of the jets were leaking. I re-sealed everything, rebuilt the 2 main motors and added an additional circulation pump for heating. I also bought a brand new control module with a 5.5 kw electric heater.
Fast forward to September 2023 and I have installed a 5kw solar system with a 30kWh battery that is working amazing. Here is the graph of my solar / consumption:
My hot tub heats 10-11 times per day using avg 6100w for 20 mins each time. This ends up being about 21.9kWh per day, 657kWh per month. This is nuts...I know people on this forum say that a hot tub really drains the power but I had no idea!
My solution was to purchase a natural gas tankless water heater off of craigslist (cost me $100) and use that in place of the electric heater currently in use:
I tested it and it seems to be heating properly up to 140 degrees.
