We have a pro build Boat . At some stage the heating pump has been changed and a pump with 15 mm connectors. Has been installed The original pump was 22 or 28 mm
What would be the best replacement pump to help with the flow rate and an diesel stove on it also has a clarifier on the system . We. Don't like the idea of a back boiler in 28 mm copper to 15 mm though a pump then back to 28 mm copper tube.
Can any body help.
Kind Regards NB wild kitten. Tracey &Steve
