Turn your Stock Tank into a Hot Tub!
Using a simple propane outdoor water heater from Amazon, you can turn your stock tank pool into a hot tub for as little as $200 (for a small heater). Depending on your pool size and water temperature, allow 1-3 hours to heat to ~90 degrees. These propane water heaters are designed to be placed outside and use propane from a standard 20 pound tank, the same as your portable gas grill!
Note: you’ll need to mount the water heater to something sturdy like the side of a house or a fence. Be sure to follow water heater instructions carefully and avoid mounting anything above the exhaust pipe.
Step 1: Pick your heater size
There are three sizes of propane water heaters, varying in price from about $120 - $330.
Small Propane Heater 6L (Amazon): Great if you have a small stock tank (smaller than 8’). Or, if only need to add 10 degrees to an 8’ stock tank, it can do that in about 2 hours.
Medium Propane Heater 10L (Amazon): Perfect for large stock tanks, this is the one I use and recommend for most people. This heater can heat an 8’ tank about 10 F degrees per hour, or from 60 degrees to 90 degrees in about 3 hours. See the unboxing and setup video for more!
Large Propane Heater 16L (Amazon): This is the grand-daddy propane heater! It can heat a stock tank from 50 F degrees to 100 degrees in as little as 2 hours.
Step 2: Install the heater and pump.
