This will Provide an Improvement in the Operational Efficiency of the Boiler, Reducing the Primary Energy Usage and Tunning Costs


This Gledhill Torrent Stainless OV allows the homeowner to utilise inputs from a wood burning or solid fuel boiler to supplement the energy generated by a conventional boiler. The Torrent Stainless OV can be programmed to maximise all alternative energy sources, before diverting to a conventional boiler. One of the benefits of the open vented boiler configuration is that the whole output of the boiler is available to the thermal store. The TorrentStainlessOV provides high-performance mains pressure hot water via the plate heat exchanger. The heat energy provided from the primary heat source and/or solid fuel input is circulated from the store to the central heating circuit, allowing rapid heat-up of a radiator system.

In situations where no gas or solid fuel source is available the Torrent Stainless OV can be used exclusively from the two 3kW electric immersion elements which will provide both hot water and heating for the property. The obvious application is apartments where no gas main is available, but this could also be appropriate where electricity is available from a renewable or low carbon source. It is possible for the auxillary heating to be supplied from the store, but this is only powered by the lowest immersion. It is important to note that the design heat loss, of the rooms to be heated, must be less than the lowest immersion power.

If connected to the standard grid then the thermal store is the perfect solution to maximise usage of an off-peak tariff where arrangements should be made to power the lower immersion element, in order to minimise the running costs.


Please Note:


  • Additional height for feed and expansion tank will need to be allowed if it is to be sited in the same cupboard
  • Vent pipes shown through the side of the feed and expansion tank may not be suitable for all systems. Installers must check suitability
  • The standard open vented store relies on a feed and expansion tank suitably sited above the highest radiator point to provide sufficient head for the system
  • The feed and expansion tank must be sized to take the water expansion of the whole system (ie. solid fuel boiler, cylinder, open flue boiler and auxiliary heating)
  • The feed and expansion tank is not supplied as standard with the unit


Key Features of Gledhill Torrent Stainless Open Vented Cylinder 180 Litre


  • Utilises open vented boiler to heat the store directly, with 3kW immersion heaters for emergency back-up
  • 3kW immersion heaters available when electric only is used as the primary heat source
