I am considering building a new enclosure for my EWDs.
I have previously built fake rock walls using rendered polystyrene and colored oxides which look great.
I want to build a larger enclosure for them and want to get rid of the ugly heat lamp hanging into the enclosure.
I was thinking of using heat cord laid in a zig zag in the polystyrene I will use for fake rock wall/ basking shelf, then rendering over it. I want a heat source that is effective, and is not visible.
If I do this I am thinking of creating a heat gradient by laying the heat cord close together in one basking shelf/rock and further apart in others so my EWDs can choose what suits them. i will also run a thermostat to keep overall temperature controlled
I have read a few threads about heat mats burning due to a lack of air flow around them, is this also a problem with heat cords??
I have a couple of possible installation methods in mind. I was thinking the heat cord could be used similar to underfloor heating in houses. This is laid in cement bedding under tiled floors, under carpet, and on the underside of timber floors and sandwiched in place with polystyrene insulation sheets. As far as I can tell, heat cords are a similar concept/product.
option 1 use a router (or hot soldering iron) to cut grooves into polystyrene, line grooves with foil tape, lay heat cord in groove, then render over it as per the rest of the rock wall.
option 2 set a ceramic tile (or slate) into the poly styrene, glue heat cord onto tile, then render over the top of it. this method would give me some separation between the heat cord and polystyrene.
Does anyone see a problem with either method?
