Am wanting to wrap my wood burner with 3/8 soft copper pipe to heat water going to an heat exchanger in my furnace. Will the copper withstand the heat?
Most alarms work well enough, but my son came up with an interesting twist. He put the siren inside the car, hidden enough that a thief could not spend the time to find it and rip out the wires. When the alarm goes off the inside of the car is filled with siren noise way beyond the threshold of pain and it is hard to loot or steal a car with both hands clamped over the ears. Coupled with an immobilizer it should be pretty effective. He also put a hidden kill switch on the electric fuel pump of his car. The car can be towed away but not driven away. A cheaper but less convenient way to do the same is to remove a critical fuse, like the one for the ECU (fuse #32). The car won't start and it would take a thief too long to figure out why.
I assume you've ruled out some new animal in the area bumping into the car and running away before you see it? The type and setup of the alarm would help, but that may be beyond the level of this forum. If you have a proximity sensor those can sometimes get triggered by random wireless signals. Also consider the possibility that someone has your remote control code, and is messing with you. By sheer coincidence over the years, I've been able to arm/disarm two other vehicles in random parking lots. But my alarm is a mid-90s model, and code security has probably improved since then.
1064?C or 1960?F How hot a wood fire gets depends on the draft and other conditions. Various references seem to mention 800?F, although a catalytic converter can raise that to 1200?F as it burns carbon monoxide. .
