Rectangular

McDonald Water Storage launched their CUBEflow rectangular tank in 2011 to provide direct replacements for the discontinued Elson rectangular water heater range. As well as purchasing machinery from Elson, we also employed a number of key members of the Elson team, including the highly experienced, Production Engineer and Technical Sales Manager, Doug Rodgerson, who brings almost 25 years of experience and knowledge from Elson and their predecessor, Elsy and Gibbons.  This has enabled us to bring the core strengths of the Elson Water Heater and combine them with our technical expertise to offer a solution which can confidently claim to be an exact like for like replacement.

The CUBEflow hot water tank range has a selection of water heater cylinders that can be heated electrically, or indirectly by a gas or oil boiler, multifuel stove or log burner, solar thermal, heat pump, or a combination of these sources.
