Hi Everybody...I'm a newbie to this message board and hopeful I can obtain some great information. I'd like to change my existing Central Boiler 6048 circulating pump to a 12v model that I can run simply on solar panels and deep cell batteries. Any suggestions or ideas is greatly appreciated.

No more current than the pump uses, I would think it would take forever to get your money back on solar panels and batteries. Just my thought. I think it is great that you are wanting to try things like this. Keep us posted if you do it!!

A lot of folks are totally off grid... You'd be surprised how many

Forgot to mention that I've already purchased the panels (2@35w and 2@70w) for $150 on Craigslist and have about five deep cycle batteries here that I've acquired over the past year. Just wanted to see if they even make a 12v pump.
Thanks for your replies!

Yea, it's called a 12v to 120volt adapter--cost about $15 on line for the adventurous folk' looking for
another way to "follow the yellow brick road".... :bash:
Guess I will never understand.....

If it were me I would get an old battery backup and open it up and connect the batteries you have to it and then run the pump through it. (if you want the pump to run when power is out)
Then just get a grid tie inverter and put connect the solar panels to that. It would be a lot more efficient.

After lots of searching, I've come up with this Topsflo 10pv 12V solar powered hot water circulation pump.

Any thoughts? I'd really like to take my Central Boiler completely off grid. The solar panels are sitting in my barn just waiting to go up.
Thanks for any ideas!

Not sure how the solar panels work. Do they have any built in regulation? What is there voltage range? That pump has a huge input voltage range. You could likely just tie the panels to a battery via a diode. Looks like it only draws less than an amp. Then as a safety, you could get a wall transformer and hook it in with a diode too just in case the batteries start getting low and there is no sun. I would look for a 10V wall charger.
Is that pump big enough though. 1/2" pipe and only 2.6gpm seems pretty tiny. Would not think you could get much heat out of that.
I would need the details on the solar panels to really design the system out. I have never worked with them.

That pump is way too small.
You will be way better off just getting a 300w one of these and plugging it in an outlet http://www.ebay.com/itm/300W-500W-1000W-micro-grid-tie-inverter-for-solar-home-system-MPPT-function-/271049903292?pt=LH_DefaultDomain_0&var=&hash=item3f1bd54cbc (http://www.ebay.com/itm/300W-500W-1000W-micro-grid-tie-inverter-for-solar-home-system-MPPT-function-/271049903292?pt=LH_DefaultDomain_0&var=&hash=item3f1bd54cbc)
Will be way less headache than trying to use 12v pumps and batteries.
