usmcjsy, I have an Attwood forced air furnace in my perm. I can run a full weekend easily, (Friday afternoon to Sunday late) with the house maintained at a comfortable temperature on 2 batteries. I have the house circuits divided that the primary lighting, TV and radio are on 1 circuit and the heating, circulating fans and a secondary/emergency lighting circuit are on the other. I also have a built in jumper circuit (just in case). I run 2 Trojan SCS-225 Outdoor series 31 batteries, that during the summer are my trollers for my boat. This winter will be the 9th season on them, the reciept shows 5/2001. I figure in another 1 or 2 seasons I'll need to replace them with fresh. (You can BET they'll be Trojans). I think I got my money's worth. Phred52

I have another question about a forced air heater. I have a 6.5x16 ice castle with a forced air heater. Is it worth while to put in a fan or two to keep the air flowing? Any recommendations on a fan? Anyone play with the new clam LED/fan combos? Thanks in advance.

jfish21, YES!! In my house (6.5x16') I have fans mounted 3" from the ceiling pointed down and toward the windows. Each is seperatly switched so I can turn on or off the ones that are needed. They are just computer (12volt 'muffin fans'). They keep the windows from fogging over and help equalize the temp from ceiling to floor. Phred52

where the best place to find Mono-Crystalline 50 W solar panels?

hibanks1...check out that bay area on the internet or email me at rosatti1@yahoo.com. The key to a good working panel is to get a good one.
