Rory Posted December 14, 2005 Report Share Posted December 14, 2005 Hey my water felt a little hot this morning..... ....soooooooo.... I checked the budget thermometer floating around...26-27 Deg C I then checked the heater...set to 26...heater still running Still felt hotish so i got a quality food thermometer...30-31 Deg C I turned the heater right down and it went to 20 befor it turned off, i then turned up and it stayed off for a bit then turned back on (26 Deg C setting). Whats going on here? is my thermostat blown? are all the thermometers wrong? help... i don't want to boil my fish!

alanmin4304 Posted December 15, 2005 Report Share Posted December 15, 2005 The thermostats are not accurate and usually don't give a temperature the same as it is set for. This can be for all sorts of reasons. It also takes a while for the thermostat to change temperature after you reset it. All you can do is test it agains a reasonaly accurate thermometer. I have two identical ones which are both set to the minimum (18 deg C) and one operates at 25.5 deg and the other at 26.5deg) Quote Link to comment Share on other sites More sharing options...
Rory Posted December 15, 2005 Author Report Share Posted December 15, 2005 .... I have two identical ones which are both set to the minimum (18 deg C) and one operates at 25.5 deg and the other at 26.5deg) Do you think that is just terrable!? I mean we pay for these damn things and they seem to be less accurate than my damn toaster! Im sure it can't be to hard to make them accurate.. ...So where can you get good heaters with an accurate, digital thermostat? As im new to this hobby i have little knowledge as to which are the quality brands. Whats your setup? Do you guys/girls use quality thermometers and heaters or $1 rubbish ones like me? I was reading a post the other day about a blown thermostat...is there prevention for this? (listen to me i sound stressed out as! lol) Rory :-?

alanmin4304 Posted December 15, 2005 Report Share Posted December 15, 2005 I have some of each but I also have an acurate digital thermometer to check them against. Most new ones are reliable if you take note of wether they can be submerged. They don't run well when wet. They are not very accurate though. I have just bought two electronic thermastats at over $140 each and they are still only acurate + or- 1deg. Quote Link to comment Share on other sites More sharing options...
Feelers Posted December 15, 2005 Report Share Posted December 15, 2005 Does anyone know how good Sacem heaters are? They are from Italy, and look really well built, but has any one tried of these? Quote Link to comment Share on other sites More sharing options...
