Hydor THEO Heater 150 Watt Information




Theo 150W For Aquariums 23–40 gallons
New aquarium heater functioning with the exclusive PTC (Positive Thermal Coefficient) technology.

The Hydor Theo heater line features PTC patented thermal technology which makes it among the safest aquarium heater lines on the market. UL Listed by design, not by the use of accessories. Made from specially engineered shatterproof glass which, while not unbreakable, is designed to resist breakage in most normal aquarium situations. Highly accurate due to the use of precise micro-switch technology. For use in freshwater and marine aquariums. Two year manufacturer`s warranty. The 50W & 100W/150W models, at 7" & 8.9" respectively, are among the smallest sized heaters on the market. The Theo "minimum water line" requirement must be followed for proper operation.

Features:
  • The first shatter-proof heater thanks to the peculiar glass tube.
  • Maximum security: THEO is shock resistant thanks to the PTC heating element and the shatterproof glass tube.
  • Free positioning in aquarium with supplied suction cups.
  • Self-limiting: the patented PTC heating system guarantees operation in complete safety because in case of dry running there is no danger for damage.
  • Complete range: 3 new sizes 25W, 150W and the unique 400W.

Comments: I am using my heater in my saltwater mixing tank. Out of box the temp gauge was right on what i set it to 78.I bought the 400 watt heater was a overkill for mixing tank but plan on using it for backup heater for 80 gallon tank if needed. Very happy with this heater and price would buy again!

Comments: Hydor makes good products, but these heaters are terrible. I have a pile of them I need to send back to hydor because they either won't turn on or won't turn off after about 6 months of use.

Comments: I had the 400W version of this heater and when I went down stairs tonight I was shocked when I touched the sump. I found out that this heater had split open and was spewing electricty into the tank. The heater is less then 6 months old and its already died. I have had to Jager heaters for 6 years w/o issue. The only reason I didn't get another one of them when I bought this one is b/c I needed a bigger heater for a new tank. Worked good at first but like I said didn't last long at all.

Comments: Our house gets very cold at times and this heater does a great job in my 3 gallon tank. It fits well and doesn't take up much room. It is making it possible for me to maintain a healthy and happy freshwater tank. Couldn't recommend it more!

Comments: been using one for several years now - no problems. It's a pretty tough little heater - great for 10 gallons. It holds the tank around 80F when it's around 65F in the house.

Comments: Bought 2 of these to heat my 75 gal. saltwater tank. They has been a pain right from the start,hard to adjust,turned all the way down and they still raise the temp to 80 degree. Good thing I had a chiller or I`m sure my tank would be wrecked. Took a bit to figure why my chiller kept on coming on, this was why!!

Comments: I bought the 300 Watt unit as it fits my requirements... Its 15 inches long! I have to be creative with placement as its too long to tuck in my sump, my original idea. But it does have a very accurate dial setting. So I think its a decent unit. Maybe you might buy two 150 watt units that are shorter to be able ti hide them out of sight.

"As always my experience with Marine Depot was 'overall satisfaction.' If on the phone, by video or the write-in reviews on the product I am interested in, they are always helpful. When I am in doubt of what product will help me or where to find it, Marine Depot is usually the first and last place I go to."
