Coil Kit Installation Summary | Off Grid Wood Fired Hot Tub 

Called a thermal syphon this kit is a rip off !

We used a 64mm hole saw drill bit. Any size between 64mm and 70mm will work with our coil kit

You pump it with a gas honda pump. Look them up.

A round stock tank pool 8ft in diameter and 2 ft deep holds around 750 gallons of water. The stock tank in the video holds 200 gallons and heated up in 2 hours. Your large stock tank would take over 5 hours to reach 104F. If the stock tank is uninsulated and the ambient temperature is too cold you may not reach hot tub temperatures. You could use two coils simultaneously to achieve a faster heating time

Yes, it works great for that

It comes with the kit from us at Salty Barrel

Do you guys make a coil that would wrap around a standard metal barrel

@@SaltyBarrelhow do I buy the kit?

No pump needed. The heat from the fire causes the water in the coil to rise so it circulates naturally without a pump. This phenomenon is called thermosyphon.

@@SaltyBarrel Что ж здорово, а хотелось узнать что за трубу используете в змеевике, не поржавеет ли она по истечению времени или не поведет ли???

@@SaltyBarrel Задумка неплохая, нужна только подложка снизу,чтоб ветер снизу поддувал
