These are still the most popular cylinders for storing hot water.  A large tank (cold water storage cistern) in the loft supplies cold water to the base of the cylinder which then pushes the hot water out of the top of the cylinder, and onwards to your tap outlets.

This means that your hot water is ‘gravity fed’.  (Usually, for a good shower experience an additional shower pump will be required).

Modern cylinders are supplied factory insulated and will retain the heat much more efficiently than an older cylinder with a ‘jacket’ for insulation.

We supply & install RMCylinders or Gledhill depending on your requirements.
