225×300 100W aquarium heater test
Start the test heater temperature is 20.3 degree
I have an aquarium at home so I’m just going in 1.5 liter bottles tested heater for how much it is heated from 20.4 degrees Celsius to 29 degrees Celsius .
The disadvantage of this test is that to give a bottle heater and how much heat rises to the mountains this is the effect that the water reaches the top of the bottle quickly 29 degrees , which is much lower surface warms .
Well aquarium heater ‘d placed down so the heat was rising up through the full height of the aquarium and would like to be there with circulating water filter .
Surface water was heated for 5 minutes and 15 seconds which is a good result.
Heating thermostat stopped when the water reached 29.7 degree that I measured with a thermometer sensor
