I spoke again to my plumber - seems the main thing is that the Mersey is still
in production, while the Medway was discontinued 3months ago. He further said
that the only difference between the models was that the Medway had a flow rate
control at the heater (rather than at the tap), and noted that this was in
reality a rheostat rather than a thermostat. And so, being a flow rate
inhibitor you could achieve the same thing by turning the tap further on or
off. I suppose, therefore, that Baxi deleted the Medway since the Mersey was
doing the same job in practice. Is all this correct? Andy
