For July’s product of the month we are supporting the McDonald ELSOflow – a rectangular, copper hot water tank which is the perfect like for like replacement for the original Elson hot water tanks.


McDonald Water Storage specialise in manufacturing a variety of hot water systems and launched the ELSOflow tank in 2011 to provide direct replacements for the discontinued Elson water heater range.  The rectangular tanks were originally designed as space saving solutions to fit snugly within tight areas, such as airing cupboards and lofts, and were fitted widely in the 80s, 90s and 2000s in social housing and housing where the space was at a premium.

The McDonald ELSOflow is the only tank on the market that is direct replacement for the Elson tank. It can have the connections custom located for convenience, meaning that replacement installation costs are kept to a minimum. Whist the ELSOflow is convenient as a replacement, it also requires 27% less space than a cylinder.


Other benefits include:

  • Direct replacement for existing Elson tanks, providing a simpler installation and reducing disruption to the homeowner
  • Available in a range of standard sizes for like for like replacement, or bespoke designed to suit the installation requirements
  • Flexibility with models to incorporate a range of heat inputs including  electricity, gas, oil or central plant boilers and renewable energy
  • Fit and forget solution – open vented water heating
  • Models suitable for either floor standing, on a frame or wall hung
  • Being copper provides complete peace of mind, killing 99% of bacteria
