Bottle heater question

Has anyone used two bottle heaters off of one 12v source? The reason I ask is that even here in Florida I have trouble heating the bottle to 950psi @ 70 degrees.

It's not the 12V source you need to worry about, its the AMPs the heaters draw and what the fuse your source has. If the Heaters only draw 8amp each then any 20amp 12v source should work. Best bet would be to just run a wire from the battery to a toggle switch with an ample fuse inline.

Thanks for the response. I have my bottle heater wired to the batter and a a toggle switch already. Where the toggle switch run to the heater could I splice into the existing two wires that run to the heater and run two heaters On one switch? Not sure what the amp draw on the Zex heater is.
NVM i got you on the wire size you may need
For 15' of wire with a 15A or 20A draw you need to use at least 10 Gauge wire.
For 15' of wire with a 25A or 30A draw you need to use at least 8 Gauge wire.
For 15' of wire with a 40A draw you need to use at least 8 Gauge wire.
Here is a Chart you can use for reference.

You need to get a hold of Zex and see what the max draw of 1 heater is. IF and ONLY IF you have a strong enough switch and fuse can you run them on a single wire. You need to do some research and find out what guage of wire you need for the amps needed and the distance of the source from the battery.
