Testing

The primary things that were tested for the device were the temperature of the water from heating, the amount of time it will take for the water to heat up to the desired temperature range and the output flow rate of the water so that it is in the desired range.

Test 1:

Steps:

Clamp the device to the table. The side parallel with and furthest away from the heater should be clamped.
Place the outlet tube into the large bucket.
Connect the hose to the inlet of the copper piping.
Connect the burner to the propane tank.
With both ball valves all the way open, turn on the water from the hose.
Open the valve for the propane and open the valve for the burner as well. (Make sure the maximum amount of air flow is allowed into the burner by adjusting the plate at the end of the burner.
Light the burner through the opening where the coils are seen.
Adjust the ball valves to dial down the flow rate of the water until the desired temperature is reached. Do not shut the inlet ball valve and make sure enough water is flowing through the coils to ensure some flow out of the outlet pipe.
Using the thermometer, measure the temperature of the outlet water.

Test 2:

The second test that was done for this project was to measure the output flow rate for the hot water heater. A 1 gallon bucket and a timer were used to see how long it would take to fill the gallon bucket at the desired temperature. This was tested five times and the numbers were averaged to come to a final number. This was then converted to gallons per minute to determine if the device met the flow rate requirement.
