I have had exceptional experience using Hartel brand brushless DC
circulation pumps on my home's solar hot water system.

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
