3 strikes you're out.

I've installed 3 of these boilers. Each one has had significant problems on startup. They're very finnicky. The domestic flow switch is made of a plastic impeller and they wear out in less than a year. The the heat exchanger is a push fit onto the internal piping with gaskets...They leak. They're excessively large and heavy too.
