Why are the aquarium heaters expensive?
A tank heater can be more expensive and less expensive depending on watts. Usually, they are costly because they have to supply heat consistently and need proper machinery that serves the purpose. It also depends on the type of aquarium heaters.
The most common placement of a heater in a tank is submersible to distribute the heat properly. For this reason, a heater should be waterproof and energy-efficient that can work consistently without stopping.
Also, a larger tank requires more heat, so you have to choose a heater with more wattage rating, and it will cost more.
What is the running cost of an aquarium heater?
A fish tank heater has a moderate cost of the run, and you can determine its running cost per month by calculating the used wattage. Generally, heaters consume considerable electricity to run efficiently, as they supply heat in the fish tank.
Mostly freshwater fish require a temperature around 78 to 80 degrees Fahrenheit. The continuously working heater increases your electricity bill.

How to reduce the running cost of a fish tank heater?
Usually, the running cost decreases in the summer as the atmosphere is already warm and you can turn off the heater at night.
The running cost increases too much in the winter where you can not turn off the heater due to cold, freezing temperatures.
You can reduce cost by turning it off for a few hours but make sure to stabilize the temperature inside and rendering heat release or escape out of the tank.
