This is a very cool instant hot water heater that can run off of regular cooking/vegetable oil and generate heat/hot water for your home for up to 24 hours running on a single small tank of oil.
This instant hot water heater only weighs three pounds. It is very lightweight and can be carried in a backpack and used in a case of a power outage or emergency.
Also, any water can be boiled down so that it can be used as drinking water in case of a water outage. In case it is used indoors, an exhaust pipe has to be installed to vent the fumes outdoors so that the heat radiation can also be used as a source of heat.
For the sake of the video, we used a small fountain pump, but a heat pump may need to be used that is designed to handle boiling water temperature.
