Electric Storage Calorifiers

Ancillary Items & Options

GMS Electric Storage Calorifier
  • Pressure Relief Valve: Needed for all unvented calorifiers and where working pressure exceeds 25 m.w.g.
  • Temperature/Pressure Relief Valve: For unvented systems there is a requirement for a temperature relief valve. This is usually combined in one unit with the pressure relief valve.
  • Pressure Gauge & Gauge Cock
  • Temperature Gauge
  • Anti-Vacuum Valve: Anti-vacuum valves are needed for all copper-lined steel calorifiers. They may also be fitted to copper calorifiers where there is a possibility of partial vacuum.
  • Automatic Air Vent: Normally only needed on unvented systems
  • Inspection Opening: Offered as standard unless specifically excluded. Inspection of the calorifier internal surface is possible when the tube bundle or immersion heater is withdrawn. If better facilities are required for inspection, or if construction is to BS853 (see below) then the inspection opening is required.
  • De-Stratification Pump and pipe-work: Timed to operate during periods of low demand, will ensure the complete heating of the calorifier contents at least once a day to kill legionella bacteria. We can offer a suitable pump and pipe-work assembly for new or existing calorifiers.
  • Sacrificial Anode: Except for unusually aggressive water a sacrificial anode is unnecessary. For galvanised calorifiers an aluminium anode is best. For copper calorifiers a magnesium anode would be offered.
  • Expansion Vessel: An expansion vessel should be connected to the cold feed pipe of unvented calorifiers.
