THG vs Flexwatt...

Actually that picture is a little mis leading, though I do not think intentionally. Might have been worth you asking about it though-

I make racks a many of you know. I machine a slot in the shelves with an small lip on it to retain the element in place. Works great BUT the element I had been using for years varied a bunch in width. Not a gripe, that is what happens to the laminate as it warms and cools- it stretches and contracts during the manufacturing process. Fact of life on something like this. The tension on the reel can cause it to stretch as it is rolled which can make for narrower element. We are talking 1/16-1/8". This meant that we would need to test each roll that we got in to see if it fit our slot width properly. Too wide it would bow in the middle and too narrow it would not stay in place. We tried each roll as they came in and when we "got lucky" we would set that roll aside for racks. We originally had two cut files, one for wide and one for narrow batches but the problem there was sending replacement element to people sometimes years after purchase. The difference is very small but can be very significant as the lip can only be about 1/8" to start with. I have had 2 other rack makers ask me about this over the last couple of years with the same issue. Luck of the draw.

So now we are making our own one of my requirements was a way to more consistently get the same width. If you bother to look you will see that the bottom layer in your pic is wider than the top layer. That is intentional and it is trimmed to width after it has been run so we can get a much more exact width AFTER it cools. If you are taping it down then none of this matters but if you do what I do it is a big plus. Once we got this worked out I have not had a single roll of 4" that I can not use in all of the rack shelves I produce. Kind of convenient for us reptile folk both now and in the future. Sorry your box got squished bending your corner- So how about you take the 2.5 seconds it will take to trim the end? The laminate will not de laminate any more or less than any other element. The bottom is simply wider than the top.

So while MasonC2K is sort of right he is also not. Seems to me storage containers were originally used for storage. Now several reptile related manufacturers make tubs of the same dimensions but with characteristics for reptile use. Are they hacks? I guess maybe, but that is often how things get improved.

Kitedemon, you seem to think your perfect world is every bodies perfect world. My world must be very different from yours then. The element you described will be available someday I am sure, but today is not yet that day. I will continue to work towards a self regulating element and that day will come but it has not yet. Have a little faith. If you do not want to use it then don't but even you must realize that your conditions are not every bodies conditions and even if you had what you wanted it would still not be right all the time and you would need to regulate it anyhow.

Yes agreed it can happen when a box is damaged but clearly could also happen with sliding a plastic tub over the edge, why is it so hard to say it has an up and down side to protect against possible problems? Better yet IMPROVE the product! You sent a sample for me to test I did not ask you to do so.

Do not disinfect the tape. OK, that is a MONSTER down side, and perhaps you should mention that in your instructions. Most of us choose to disinfect racks once a month or so, the need to remove the tape monthly, is going to be a problem. Again it has a simple solution, tell people to seal the open end up. When you sell a wire kit include enough pads to do so.

I have never needed more than 100ºF there are a growing number of UTH on the market that all are regulated. I run my set up in a room averaging 62ºF for most of the year. It is hard to imagine running in a cooler room to me but hey I guess some do. I know that many animals have been burned by flex watt in the past. It runs cooler than THG so one would guess it runs a higher possibility of buns in the event of a t-stat failure. Low temp tape is the final fail safe.

Instead of doing damage control would it not be better to make the product better? Is that not the point of why you sent the sample to me in the first place. It is what I do, half my job is product evaluation. I find flaws. You sent the sample I never asked for it. The laminate is short of one side it is prone to catching edges (like what happened in shipping) if you place it down problem solved. The solution is super simple but rather than see this you get defensive. Just let people know to place the side you can read UP. Problem solved costs NOTHING. Instead rather than post a hey this could be an issue note you have become defensive. As a designer you simple cannot afford to be defensive you should be proactive and find anything that could be an issue and address it before someone has a big problem that causes harm.

This is the same way I build mine, the proper way is to protect the tape :gj::gj:

Far from perfect Rich. The issue isn't how it delaminated but that it has delaminated at all. It should never have happened. I am pointed out what is top me a flaw. That the layers if you bump the corner it come apart. I believe that repeated sliding over this weak point has a potential to delaminate over time. I am also suggested a simple easy and free solution. The unconcern for others safety is shocking. I expect that kind of attitude from non reptile people but not from a reptile person. Unless you have done cycle tests on the product no one has any idea if the product can delaminate. Keep the short top side down. Simple solution it will not effect performance of the product and does not effect the price.

You can't be serious with this?..... I thought it was common sense that you either tape that end up or don't put liquid in there because there's electricity flowing through it. :confusd:

I was given fully wired strip. I actually did not ever notice it was open.

Tape likely isn't enough to keep disinfectants out, the pads they supply would be great but the wiring kit has two not four as I suggested they include. Simple solution. Would it not be nice to get a product and a kit to assemble it with ALL the parts you need rather than incomplete?

I personally found the pads they supply to be more than plenty, I trimmed mine a bit and used some where I soldered and some over the distal cut end. It more than covered enough.

I also would think that it should be common sense to prevent tubs from scraping directly over the tape by either routing out a recess for the tape, or covering the areas the tub edges slide over with something. I've read about ppl using window shims for this, I use plastic. Correct me if I'm working but even strips of foil or electrical tape should work for that I'd think.

Edit: not everyone has the option to have only one side up. A lot of racks are built to where it's one continuous piece of tape winding from one shelf to the next, one shelf one side will be up and the next the other will be.

I recently ordered one of the THG kits and I just cut the pad into smaller pieces. The ones they send around almost 2" square which to me was overkill.

First off I quess quoting took the day off today LOL

I am still trying to rap my brain around your thinking.
I am not trying to bash you or pick on you at all, just understand you reasoning.

I am responding in blue here............

I do agree that RB never should have sent you a section for free BUT you also wanted to play a big part in the last THG/Flex A Watt debate

Did you not ever wire Flex A Watt?? You have to seal BOTH ends unless you want a little love bite. Also if you have a commercially built rack you shouldn't have more than 4 points of concern. BTW you really only need to disinfect any surfaces that your reptile has/can touch. **I wont bring up the lid thing again, I promise**

Just because YOU don't need it doesn't mean others don't. I am not talking just snakes either. Do you think THG is only used on ball pythons? My dragons are in our living room that stays around 72 degrees year round and they all have heated floors, they run at about 115 degrees to keep 92ish surface temps. I don't know all of the requirements for all reptiles but I do know uromastics(sp) require even hotter temps. So you need to remember that there are a lot more uses than just yours.

Most commercial built racks use one long piece that is in its own grove, the tub will never touch it.

What did you get in a "kit" from flex a watt? I know the clip covers were not water proof. Liquid tape can solve all of your problems.

Now if you are using THG or flex a watt in anything but a commercial built rack you are now dealing with a custom/modified system. Heat tape is about the most fool proof product in my mind. I don't know why everyone wants to make such a huge deal out of it. I know I am not the smartest person in any room but I guess my mechanical inclination is more than most.
If you are using one piece per shelf its not that hard:
1-Connect your wires however you are comfortable but note that soldering is by far the best contact.
2-Insulate your connections AND the other cut end of the tape.
3-Use the tape of your choice to hold down all four sides of the heat tape to the shelf.
4-Make your power connections of your choice
5-USE A STAT!!!!!!!!
****My OCD kicks in on step #3, I only use aluminum tape and its one layer on the back, two staggered layers on the sides and three sacrificial staggered layers on the front.

Hasent been that hard for me but I do know a lot of people tend to overthink things.

I think my point has been lost.

I was very kindly given a product to evaluate. I then came up with initial evaluation and reported it back privately. Then when people speak of using the product I reported what could be issues. And get jumped on.

The product CAN be delaminated. The point I made is protect it from having the edge damaged. If the product is placed with the reading side up (not upside down?) it adds an additional safety. I don't want to see any one have a serious electrical issue.

I did not bring up disinfecting although since it has been brought forward you can't really disinfect an electrical product while it is installed I always remove it and wash it down. No flex watt never bite me because water and electricity do not mix. After the ten min it takes the disinfectant ,I choose to use, to be effective, I dry it with some shop towel. Not THG how do you disinfect it? Seal the end with the product they supply, easy. The electrical tape I used was not enough to keep the disinfectant out. There is a flaw in the instructions, I pointed that out. The the problem is clear, I SHOULD NOT FOLLOW THE INSTRUCTIONS. That makes me a fool? For reading the instructions and following them exactly. I guess I am a fool for ALWAYS following the instructions.

The big issue is why did this NOT come from the Manufacturer? These should be in the instructions so that people whom use the product and are unfamiliar with installation can do so with the maximum safety. Safety is everyones concern, as the saying goes.

During the initial debates I asked about moisture inclusion and was told NO it is not a problem. Well apparently it is.

Do you honestly believe every person whom will ever use the product will think to a cut the pads (mine were pre wire and one was covered I din't have enough extra to cut into 3!) Rather than follow the interactions it come with? Will think they need to protect the surface? No, flex watt has taught us that people don't always think of these things there have been far to many fires and serious issues with reptile keeping.

I am sorry I brought it up. I cannot use it, I am going to replace flex watt in the rack when what I have gets worn as it costs too much to have it legally wired here in Canada.

The arrogance to believe you can develop a new product and think you have everything dialled in is monumental. It simply does not happen there is many many modifications to improve instructions and counter original flaws I actually wanted to improve a product and increase the safety.

I am sorry I wanted to help and seek to improve a product. All this for install it right side up and 30¢ in tape.
