I'll also throw in this little contraption for free. It's supposed to be an independent heat exchanger for a HERMS. Never did get the thing to stop leaking, but it's nothing a little, or maybe a lot, of silicone wouldn't fix.
No copper tubing to go with it, sorry.
BTW, any buyer is responsible for checking the safety of any of this stuff before they use it. Electricity and water can kill you. You've been warned.
There, if the microscopic print saying "don't stop taking your medicine without talking to your doctor first" at the bottom of those TV ads the lawyers put out, when they want to sue a drug company, protects them from being sued when people stop taking their meds, because the ad convinced them that medicine x would cause spontaneous human combustion, then this oughta protect me.
