ETH 200 In-Line Heater UL Listed 200 Watt for 12mm & 1/2" Hose External thermal heater which includes the PTC system. Suitable for all external canister filters
The Hydor ETH in-line external heater is designed for vertical use in most aquarium applications involving water hose of the specified diameter. The ETH must be used in a vertical manner for correct operation. The most common application is for use with canister filter, however the ETH is easily adapted for use in almost any situation where heated aquarium water is required, such as with wet/dry sump pumps. The ETH is easily installed by cutting the tubing and connecting the two parts of the tube to each side of the ETH. For reduced maintenance, it is recommended that the ETH be installed within the filter`s output assembly. As most canister filters are not designed to bear weight, it is recommended that the ETH be properly supported by the use of the attached loop to avoid stress on the output assembly. The ETH is completely safe and UL Listed. There is no danger of damage if the ETH is left running dry for short periods as the ETH will switch itself off in that event. The ETH heats with high efficiency by means of an internal heat pump system that avoids temperature variations. For use in freshwater and marine aquariums. Fits most canister filters such as the Hydor Prime, the Rena Filstar, Eheim canisters, and the Fluval canisters with the use of a short section of tubing to complete the connection. Use of the ETH cleaning brush is recommended.
Features:
Completely safe.
No danger of damage if the equipment is left running without water for a short period of time.
Patented heating element made with the exclusive PTC system. The traditional metal resistor coils have been replaced by a special polymer sheet silk- screened with heating ink.
Setting of temperature controlled by an electronic circuit with indicator light.
Connectors suitable for any flexible pipe of all external filters.
Two year manufacturer`s warranty.

Q
Is this heater for europe only or do they make them for the US market as well? I noticed in the video the heater has a european power plug.
I haven't used this long term yet, but I did talk to a few people that have had many years of service from theirs with no issue. The only negative I've found is the temperature dial seems to be pretty far off from the actual temperature.
I had this heater for about 3 months, was perfect during that time-but slowly started to heat the tank higher and higher. I have it set to 78, the tank is 90! Luckily I have discuses, so they were fine in the higher heat, but would not last too long at that temp. I had to un-plug the heater and r...Read More

Luckily I have discuses, so they were fine in the higher heat, but would not last too long at that temp. I had to un-plug the heater and replace it.Hide
Nice to get the heater out of the main tank when using an external canister filter. Temperature settings on the knob show degrees and they seem to be within a degree or two. Only hick-up was I ordered the Hydor 600 filter and the Hydor 300 watt heater with the largest (5/8") tubing connections ...Read More
Nice to get the heater out of the main tank when using an external canister filter. Temperature settings on the knob show degrees and they seem to be within a degree or two. Only hick-up was I ordered the Hydor 600 filter and the Hydor 300 watt heater with the largest (5/8") tubing connections but the tubing connections on the heater are too small for the 600 so I had to use a couple of reducing adapters. Did not seem to noticeably reduce flow. Also have another 300 watt with a Hydor 450 filter (5/8" connections) and a 200 watt on a Hydor 250 filter with 1/2" connections. The heaters were bigger than I pictured and barely fit under the tank in the stand with my over-sized canisters but it all worked. They seem to hold the temperature steady within 0.2 degrees in each tank. I have only had them a short while so we will see about longevity.Hide
I own 10 of these heaters, most being the 300 watt model
Over the years I have owned many heaters, NONE of them come close to the accuracy and longevity of the ETH. Some of mine are over 10 years old and still continue to perform as well as the day I got them. If you have a canister filter this is ...Read More

works great, so far temps have dropped to mid 30s and has been able to keep my 40G sump(set in garage) and 155G display tank temp at 72.Love the fact that I do not have to worry about breaking inside the sump and chocking my tank
