Yes, I forgot about them. Thank you for the reminder. If you have a
supplier of it would you contact me off list? Chris

I will second that, Todd. I've had a Hartell MD-10-HEH mag drive
pump pumping glycol in my SHW closed loop for 23 years direct powered
by a 20 watt PV. It does make a little noise when your close to
it...so be it.

I would look at the pump that Thermodynamics LTD of Canada sells.
Pretty bullet proof in my experience of 20 years of installing their
products. Don't deal with the people in VT. Call the business in
Dartmouth Nova Scotia, eh? Laing are expensive but very reliable.
March is not great for small closed loop. I really support dc pumps
for solar hot water unless the customer has a solar electric system
too.

Hi All,
I need to replace 3-5 El Sid pumps I'm using in a low volume
hydronic heating system. Other than laing pumps, are there any
recommendations for 12, 24, or 48 vDC pumps? Having magnetic
drives that mate with the impeller body of the El Sids, would be a
bonus.
Thanks,
Howie
