Compact 300W Heater

[DEL 707]

I've been adding equiptment to my sump and things have got a bit cramped.
My D-D Titanium 300W is VERY close to touching the walls on my sump.

Can anyone recommend a heater? Good enough for 250l and slightly shorter then my current titanium?
According to the website, the titanium 300w is 256 mm long.

I have an inkbird, so I don't need to worry about a controller.

Innovative Marine Helio heating elements are among the smallest titanium ones I’ve seen at any given wattage so far, the 200W element is 177mm (7 inches) long, you could do a 2x200W with a single controller

Unfortunately it's hard to get those heaters in the UK.

I'm using a 300W glass heater at the moment, but my temperature is swinging about.

So coming back to titanium heaters.

The Hugo kamishi titanium 200W is 23cm, which should fit.
They also do a 100W which is 20cm.

I'm going to need another Inkbird to make this work.
I need to keep my current Inkbird because it also controls my cooling fan.

If I buy 2 x 200W, should I be running them both off 1 Inkbird, or split them between 2?
Would 3 x 100W be a stupid idea?

Nothing wrong with 3x100W as long as you can handle all the cords. A single 100W heater failing out of three is less of an emergency as well

You should be able to run multiple heaters off of one inkbird but you’ll probably need a splitter to get 3 on there, I think most models have either 1 or 2 heater outlets

2x150 or 2x200 might be less expensive to buy than 3x100W
