Comments about Aquarium Heater by Deltatherm:

Bought 300 watt, Set to 25 and the themostat goes on for 5 seconds then cuts out even turned it up to 30 and does exactly the same even though the actual temperature is 20. Very disappointed.

Comments about Aquarium Heater by Deltatherm:

I already had one of these heaters on one of my other tanks, and had no hesitation in buying another one for a new tank that I've just set up.

The original one has been in use for over 18 months now and I have never had a problem with it.

The new one that I purchased at the weekend is even better still.. The suction cups that hold it in place are better, and hold the heater exactly where I want it.

All in all, very good value for money.

Comments about Aquarium Heater by Deltatherm:

I have used this brand of heater for many years with no issues. My last 100w Deltathermheater came my new 48 litre fish box and I noticed the heater was fogged up right from when I first switched it on.

This lead me to believe there was a fault with the heater which could be dangerous. I went onto interpets web site and under the Q&A this can be perfectly normal. The fog can appear in the heater is dependant on how humid it was when the heater was made in the factory and is not a fault and is not dangerous.

The heater does keep temperature and should be used in conjunction with a thermometer. All heaters are not 100% accurate and could be + or - by one degree out, therefore there is some trial and error to get the desired temperature.

Not a good buy

By Jonfish

from Swansea on 23/4/2012

Cons:

Ineffective

Best Uses:

Freshwater Tanks, Small Aquariums

Describe Yourself:

Casual Fish Keeper

Bottom Line:

No, I would not recommend this to a friend

Comments about Aquarium Heater by Deltatherm:

Received this as part of an interpet fishbox setup. Tank is great, but this heater fails to get the water temperature to the correct level. I've got the thermostat set to 25, but the temperature barely reaches 20. This is the first time I've ever had a problem with an aquarium heater so I'm very disappointed with the quality of this product. This may just be a faulty unit, but even so you would expect some sort of quality assurance to pick this up - I could have ended up with a tank of dead fish.

Sort of ok...

By Bordois

from Scotland on 4/10/2011

Pros:

Easy to Use, Effective

Cons:

Poor Value, Unsafe

Best Uses:

Bottom Line:

No, I would not recommend this to a friend

Comments about Aquarium Heater by Deltatherm:

I had the 100W running, it kept the temperature very well, but I noticed after not so long the glass fogged up and I couldn't read the settings on the heater anymore. I thought it was just a case of needing another heater as that one must have been faulty, so I bought the same heater. Straight away I encountered the same problem of the glass fogging up. So I gather this is a typical problem with this heater. I don't think this is very safe at all as moisture inside the glass which causes the fogging could obviously potentially lead to shorting the heater, or electrocuting the fish. An unsafe product, but I will say it did keep the temperature well.

Comments about Aquarium Heater by Deltatherm:

i put this heater in my 15l tank it takes up alot of the room at the back because it has to be on a diagnal and nothing is aloud to touch it like (plants ect). it works great and has stayed at the same temprature i had to get a stick on thermometer to check the temprature because you cant see the scale very well. it is easy to change the temprature and i would recomend this to anyone.

It works!

By Mark Hewitt

Bottom Line:

Yes, I would recommend this to a friend

Comments about Aquarium Heater by Deltatherm:

They are pretty good heaters, but you should always use them in conjunction with a thermometer to monitor the temperature. The guides on tank sizes are for 'ordinary' shaped tanks. If like me you have an unusually long tank you may need the next size up, or even two of them!
