Fire Hot Tub

i was in search for a hot tub system where 1000 liter of water was ready in about an hour instead of 3 or 4 hours like most projects i've seen..

also it needs to be a camp fire to sit around with a drink or maybe grill some meat untill the water is warm

i still had in memory how hot camp fires got after placing wood above wood causing massive flames

this all combined is what i came up with..

Step 1: Buiding the Fire Cage

this fire cage is build like a camp fire so it can hold long sticks in place and is feeded trough the top ring

the water will be pumped in the bottom ring and then trough the thin tubes to the top ring

from here it will be led to the tub again

Step 2: Filled the Cage With Water for Testing (three Little Holes)..

Step 3: Time to Clean the Test Tub

Step 4: A Pond Pump Is Used With Rubber Hoses From a Radiator

Step 5: Everything Mounted and in Position!!

Step 6: Time to Lit the Fire!!

Step 7: Within Minutes the Flames Are Bursting Out at the Top Creating Massive Heat

Step 8: After Just One Hour the Water Temperature Reaches 40 Gr. Celcius

Step 9: Next Morning, the Water Still Has 30 Gr. Celcius

Step 10: This Thing Did an Awesome Job, Time to Make It for Real!!
