DIY Inline aquarium heater
My first blog, be gentle ;). Here is a guide on making your own DIY inline aquarium heater.
Although inline aquarium heaters are available, they all have internal (or very small readouts to adjust the temperature)and the biggest wattage I could find was just 300 watts.
With my new aquarium ordered, and someone who likes building my own equipment I thought I’d attempt making my own with a Bigger display, easier to access controls and 500 watts heating power (the new tank is 5ft x 2ft x 2ft and has a large sump and will hold close on 700 litres in total).
Although this tank will be for Coldwater Fancy Goldfish, I like to have a way of ensuring it doesn’t drop below 20 degrees C, esp when doing water changes (more on that soon when i finish my water change station, but it is going to make water changes a doddle). Anyway, back to the build.
What you will need:
PVC Pipe (diameter/length decided by the heater size) this one is 1 1/2 inch and 14 inches long.
1 x Tee joint for water exit and heater install.
2 x hose barbs, 1 90degree one straight – plastic barbs are fine but had problems finding so I went with brass and made up with reducers.
1 coupling to make an inlet at the bottom.
1 Endcap drilled for uni seal shaft.
The photos below show how this all fits together, but Joey the King of DIY is where i got the idea for it and the link is below. There’s also a hang on the back version if you don’t have a sump or external filter.
Here are the photos that show how this equipment is put together to create a DIY inline aquarium heater:
Here is the video from The King of DIY’s Youtube channel which shows this DIY inline heater build in more detail:
