ok, so i too am in the process of replacing my LP CD-6 with the CAP-1 NG electric ignition. I hadn't bought the NG one because i wasn't sure if it generated co2 as efficiently, but it sounds cheaper anyway, so that is good enough for me.
Thanks for the info!
i have a tap right next to my room (literally 4" outside the wall) that feeds the hot water heater and it has a on/off lever so i plan on putting a Y on that an running the other gas line into my room. no more refilling tanks for me!
i may post up and let ya'll know how it goes once it is done in another month or so.
BTW- you guys pay a lot for LP, i spend mebbe 45 dollars every 6 months and i run 1900ppm co2 most of the time, in a 10 W x 20 L x 10.5 H
and personally i don't think the heat generated by the CD-6 is anything compared to a 1000 watt light. right now it is winter, and i 2 little ceramic heaters in my room to keep it 75 - 78 degrees, so i can run 1900ppm co2.
