When installed properly and correctly, a copper line from heating system can be used to heat concrete slab.
Of course as you as you protect it JUST like radient heating is considered water lines in a concrete slab
If you're talking about the copper refrigerant line then the answer is no.
No If the hole is smaller then the diameter of the supply line
Epoxy coating is a possibility for repairing lines that are run through concrete. It is a god proven technology, and is fairly costly, but it lasts a long time, and does not involve removing the concrete slab.
Looking through the top by the fan . Look at your compressor if its a heat pumpbyou will have a accumalator which looks like an long can which your copper line runs to and you will also have a reversing valve which is attached in your line sets it will have three copper lines running to it and an electrical line to it also. A straight cool unit you will see nothing but a compressor. Also if your thermostate has a emergency heat most likely its a heat pump.
Plates for printing handbills and copper was used in pots and pan bottoms. It still is today in the Revere pot and pan line of products. Copper is a good conductor of heat.
Nothing. It is water and it's supposed to do that.
Hot water line. If you did hook it up to your cold water line make sure your dishwasher is set to heat the water (some models have a selectable setting for this.)
always use copper for any kind of water installation
Yes.
its not the co.pper line its the faucet stem or angle stop
You could drain the line, sandcloth flux and solder it. Otherwise, see if you can get a compression fitting that would fit the copper tubing
