Pet Forum / Aquaria / Cichlids / May 2005Tank Heater
I have a Tank heater which has a sticking thermometer cut-out, It does not connect when the water temperature drops, But if I tap the thing the thermostat clicks in. It does disconnect OK. Has anyone taken one of these units apart, It looks like the Rubber outer case , with the control on the top is moulded to the inner plug. If I remove the temperature adjusting switch does the outer case pull off. Has anyone been successful, in stripping down a heater, and assembling it again, in a water proof working state. Or is it quicker to throw it away, and buy another one. bassett If there is one thing I wouldn't mess with it is probably the heater. Unless you have a really fancy titanium one or substrate heating cables they are pretty cheap. IMO, unless you are using several heaters that are all low wattage the risk is too great. BTW, what are you going to use to heat the tank while you are fixing this one? If your fixing projects go like mine it may be a while before you get it back together. Do you have multiple heaters in the tank? --Paul >I have a Tank heater which has a sticking thermometer cut-out, It does not > connect when the water temperature drops, But if I tap the thing the [quoted text clipped - 6 lines] > Or is it quicker to throw it away, and buy another one. > bassett I take your point, Thanks Might be an idea to just get another Heater, and then try a repair of the old one.. The dodgy one is in a 3ft tank and is the only form of heating bassett . > If there is one thing I wouldn't mess with it is probably the heater. > Unless you have a really fancy titanium one or substrate heating cables [quoted text clipped - 17 lines] >> Or is it quicker to throw it away, and buy another one. >> bassett > I have a Tank heater which has a sticking thermometer cut-out, It does not > connect when the water temperature drops, But if I tap the thing the [quoted text clipped - 6 lines] > Or is it quicker to throw it away, and buy another one. > bassett I was able to get a Hagen Thermal Compact apart with some difficulty, and worry about breaking the glass. The hardest part was to separate the plastic top pieces that clamped around the flared rim on the glass. The actual seal was a ridged rubber plug with some silicone grease on it. I think that you can clean and regrease the seal and expect it to be waterproof again. At least it worked for me. In my case I just wanted a heater and I soldered a wire across the contacts. I used a few times and then threw it away. As far as repairing the contacts, I would say that it is not worth trying. They are probably pitted, which would require that you file down to a smooth surface again. They may also be plated, in which case you cannot restore the original contact finish and the repair will not last. The new electronic heaters seem to be proving themselves to reliable and accurate too. The Hagen Tronic seems very reasonably priced at under $20, probably less on eBay. Many positive reports on the Won Brothers heaters with titanium tubes, at somewhat higher cost. George Thanks for the info, george bassett.
