Hey guys,
I recently changed over to heat cord, I made some groves in a sheet of MDF around 2cm apart wide enough and deep enough for the cord to sit flush with the board, not tight, perfect fit. I originally had a 2m 15w reptile one cord, and made the length of the board and grooves long enough to make 4 runs of the cable, I then placed aluminum tape over the cable, I made one groove a bit deeper and long enough so I could slide the thermostat probe underneath the heat cord. I had two 7l Stiema tubs siting on the tape which had dual thermometers to monitor the hot and cool ends, it was very difficult to maintain identical temps most of time, the tub on the left would be hotter than the tub on the right, sometimes it was hard to maintain a high enough temp in the right tub, I put this down to the the cable length.
While at SOFAR, I purchased a new heat cord, this time 25w 4m, I'm still getting inconsistencies, I've been testing a tub with two probes at the hot end, they have been degrees apart, Ive also tested with a heat gun some spots at the hot end are reading 35 while the thermometers read 32, obviously the heat gun may not be 100% accurate. I've now put a couple of tiles over the aluminum tape, the temps seem a bit more consistent, but when using the heat gun on the tiles they read different temps all over, ranging from 30 -37, I put this down to cool drafts etc. I have the thermostat set to 36 - 38 degrees. Any one have any ideas how to get more consistent temps across the board so I can run two click clacks on the same cord.
Cheers.
