I tried a Bolin a few years ago, when I learned of (and experienced) the relatively short expected working life of the Johnsons I had been using (which were lasting only a couple of years). However, the pump lasted no longer than its predecessor, and I didn't replace it or try to fix it. It was the motor (bearing) that failed -- nothing to do with the quality of the water in the system, and I had no confidence that another one would have a better bearing. Too bad, as the pump's energy consumption was very small. Bolin was very helpful and courteous. At one point I even ended up speaking to Ms Bolin herself. I then had a long chat with Cleghorn & Waring (which is based not far from me), and as a result bought from it another Johnson. The stated expected life was now much longer. I still have it several years later (it runs the heating all winter). C&W said then that pump design was improving rapidly, and expected life would probably continue to increase. I did consider using a standard house 240 V pump (in parallel to a DC one), using the former only when I am attached to shore power, which is most of the winter. I may yet. Adrian Adrian Stott Tel.
