To heat the water: the original method i had worked well, but the new method works better.
the best part about the new method i have for heating the water is that it is incredibly simple ! I separated all the electrical stuff including the fans from the rear bus heater, stripping it down to just the core. Then i simply place the heater core into the hot tub and drive. That's all it takes.
The old method was very related: I put the heater core into a large container full of water. Then i used bilge pumps to circulate water from the hot tub, through the container and back to the hot tub. I kept burning up the bilge pumps, so i went with the new method. |
