The heater works as I had hoped. He keeps my L46 breeding ponds stable at 29 ° C. This Eheim heater thermostat acts super processed and high quality. This heater is unconditionally know. Have some more Eheim heater in use are safe over 12 years old and still do their job. Hope this makes it that way ...
Had previously bought a cheaper L46 for this pool, which I then sent back because it was not working properly. better to spend 5 euros more and invest in a Eheim / hunter.
