Hydor makes a far better heater IMO than Eheim for being inline. When my 2262 was running, I had a hydor 300W heater inline on the smaller intake.turbid;1373090;1373090 said:the pro 3e or 2180/2080 are a bit easier to clean.. that s the only advantage they have on the 2260 etc range (plus of course the 2180 housing a heater, which is a pity the 2260 does not have the the thermo version) since they have 8 or ten thumb screws that are quite a pain to unscrew and screw back. i use a plier to lock/unlock the screws.
do the 2076/78 come as thermo versions? they would suit my needs better since they are smaller than the 2180, so more practical to house under the cabinet
