Open Vented TORRENT Multifuel Store (OV)


Gledhill TORRENT Multifuel OV - open vented thermal store

The Torrent MultiFuelStore OV is intended for use with an open vented boiler and / or direct electric immersion heaters as its primary energy source.


It comes fitted with tappings for a woodburning or solid fuel stove (with boiler capability) as standard, which can be blanked off if not required at the time of installation.

No efficiency losses through heat exchangers

One of the benefits of the open vented boiler configuration is that the whole output of the boiler is available to the thermal store, unlike the indirect Sealed Primary (SP) version where the output from the boiler is limited by the heat exchanger. This will provide an improvement in the operational efficiency of the boiler, reducing the primary energy usage and running costs.


Mains pressure hot water and heating

The Torrent MultiFuelStore OV provides high-performance mains pressure hot water. 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.


None of the dangers of unvented mains pressure systems

Thermal stores (or Heat Stores) are fast becoming the preferred way to create mains pressure hot water without the dangers associated with unvented systems. The Torrent thermal store is so easy and safe to install it is not governed by the G3 Building Regulations in the UK. What's more, if you have a suitable incoming cold water main, retrofitting the TORRENT is simple way to convert a domestic system from gravity to mains pressure.

Because there are no dangers associated with the TORRENT, such as pressure or relief valves, the cylinder does not require annual servicing like its unvented counterparts. With no moving parts you can expect long and trouble-free service from your Torrent.


In situations where no gas or solid fuel source is available the Torrent MultiFuelStore 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.

Off peak cheap rate economy tariff electricity

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

The Torrent is now available with (SP) or without (OV) a primary heat exchanger (boiler coil). If you wish to fire your boiler directly into the shell of the cylinder and run an open vented central heating system choose the OV Model. If you wish to run a sealed primary and central heating system (i.e. pressurised radiator circuit) choose the SP Model. Don't hesitate to ask for advice.
Don't forget, if you wish to add Solar Energy choose the SOLAR version

Please be aware, these prices are SPECIAL OFFERS and may alter without notice

An optional Incalloy Immersion Heater (calibrated to run at store temperature) is available for use with the Torrent range of Thermal Stores. Please be aware that whilst this immersion heater looks similar to many standard types it is designed to operate at the much higher temperatures typical to thermal stores. Installing a standard immersion heater in a thermal store can give the impression of a fault because of its inability to reach the required operational temperature.


inc VAT

An F&E Tank (feed and expansion tank) is required when installing a thermal store which provides both a vessel into which the store may breathe and means by which to maintain the store level. The F&E tank is not included with the cylinder. A 16 litre model is available as an optional extra and should be specified at the time of order. You are of course at liberty to supply and use an alternative vessel of the appropriate size.
