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 20 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 heater can heat an 8’ tank from 50 F degrees to 100 F degrees in about 3.5 hours. Or if you only need to add 10-20 degrees (in the summer for example) it takes about an hour.
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.
