Having just replaced a blocked DHW HX, any views on the relative merits of
the Sentinel

http://www.sentinel-solutions.net/en...s/systemfilter

and the Magnaclean (both stocked by BES).

The Magnaclean has built in isolation valves for cleaning; is the Sentinel a
cyclone type device which you flush periodically from the bottom of the
cone?

The Sentinel looks a bit more suited to my layout.
