For new construction, sure. There are lots of old units out there from before EZH2O was available and they just don't die quickly. There not cheap to replace if it's nonessential maintenance.
I do MEP design for commercial buildings in the US. If a job ever shows "EWC", I don't ask for specs, I assume the EZH2O until either the job goes out with that spec, or the client directly refuses to use that model.
