When I saw this heater on ebay I started to drool http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...item=2311463134
I found that there was little on the internet for reviews, but I went ahead and took the chance. I recieved the unit nicely packaged within a couple of days from www_aquacave_com , he has great customer service and good correspondence. (so you can depend on this guy if you are looking to purchase one of these units)
I was worried that one of my roommates or his friends might see the lighted display and dial and "play" with it no even knowing that he would kill my fish, so I ended up putting this unit on a tank that is temporarily at my fiance's house.
As soon as I hooked it all up I was impressed by it's "real time" temperature readout. The temperature readout fluctuates about every second, this means that this isn't a unit that only recieves a reading every 10, 30 or even 60 seconds like some digital thermometers. I also was impressed by the bright red digital readout, it lit up the room at night!
I set the dial on the unit to about 77 degrees F. The readout on the unit showed 78.4 degrees F. I went and had dinner then went to a movie, so about 5 hours later I came back and it was reading about 78.5. I decided to watch the unit while it went throught two complete cycles of heating and cooling. The heater let the tank cool down to right between 78.3 and 78.4 before it kicked in. The heater then heated until the readout read 78.9. I watched it do this twice like clock work. I then went to bed and slept for 10 hours. I got up and looked at the unit and the heater was just turning off, and it was turning off with a readout of 78.9 just like the night before.
This review is obviously not a review on the durability since I have only had the heater for two days, but is a review of the initial reliance of the heater.
One other thing I wanted to bounce off of you guys. It is pretty obvious that glass and titanium heaters are the leaders in the industry right now, but has anyone thought about the heating differences of the two? I work with titanium a lot, and in working with it I have found that it holds heat very well for long periods of time...unlike glass does. I have been wondering if there would be a benefit in having titanium over glass (strictly in terms of heating) because there would be a less drastic teperature drop when the heater turns off. A titanium heater will cool off more slowly than a glass one will. Do you see this as a pro or a con of a titanium heater?
I will be keeping you guys up to date on the new Pro Heat II heater. I look forward to hear your opinions and feedback on the review and the titanium vs. glass issue. Thanks guys! :D

Hi Superman,

The only comments I can make is that there is a large quantity of water in thermal contact with the heater so the fact titanium can hold heat better than glass is not really an issue. The heat will only disperse away from the heater via the thermal gradient between it and the water, and the water has many times the volume of the heater, so it is the heat retention of the water that is the issue (I am pretty sure this is correct, but it is a long time since I did my physics, etc. I am sure someone will jump all over me if I am wrong :) ).

Great review :thumbs:

Cheers, Eddie
 
I knew that there would be people on the forum that know more about physics than I do!! :p
 
I almost forgot, the temperature on the readout vs. the dial was 1 degree warmer on the readout, but that didn't bother me at all. Also the temperature readout on this unit was the same temperature as a thermometer that was already in the tank. The display unit for this heater acts also as the plug that plugs into the wall outlet, so if you want to be able to place the display unit anywhere you like you must get an extension chord, this is what I did. This heater has three prongs for a three prong outlet.
 
I don't think I've got a single heater where the temp on the dial matches the water temperature exactly. I always rely on a thermometer and adjust the heater gradually to get the temp I want. I have read of people having heaters with dials which are 5 degrees C out from the actual water temperature - very rare, but could be fatal to fish.

Probably to do with the speed of heat loss from the tank - type of hood, surface area, lighting, room temperature, etc. It is probably also affected by the flow rate of the water past the heater/thermocouple. The heater can only measure the temp. at it's sensor so they must make assumptions on the other factors.....

Very true, I forgot to state that the tank that the heater is on has very good water movement, not much still stagnant water at all.
 
First of all EDDIE is right you do not get much more heating from the fact that titanium holds the heat better that means it just takes a little longer to dissipate and the water dissapates much faster than glass or Ti. plus its all about conservation of energy the heat is just transfered faster in glass to the water but still transfers the same amount of energy(heat). The difference that normally comes from temp on thermo vs.heater is normally due to placement. I'm guessing if you have 4 thermometrs placed at 4 cornes every on reads alittle different but the one near the heater probably reads closest to what the dial is set to. But then again some heaters just suck. I will never buy another cheap heater after one I had took a crap and turned my tank into a bowl of fish soup :sly:
