Gledhill Torrent Greenheat SOL thermal store

As is normally the case, a sealed system boiler will feed directly to a pressurised central heating circuit and to the store (Y or S Plan config') introducing energy via the optional boiler coil. However, provision for an open vented auxiliary heating circuit output can also be made on the store. If the latter configuration is used all input heat sources will contribute energy that may be utilised by the open vented auxiliary heating circuit output.

In another configuration, an open vented boiler can be used to exclusively heat the store directly, the direct central heating circuit output in turn supplying heat to the property. In such a config' all heat sources contribute towards hot water and the open vented heating output.

Electric backup

An immersion heater element is provided and it is normally envisaged this will be used as an emergency backup for hot water and to provide emergency heat for the auxiliary heating circuit. However, if a 'renewable', 'low carbon' or cheap rate electrical supply is available, this too can be used to add heat to the store.

Gledhill Torrent Greenheat SOL Technical Specification and price list

Cylinders are fully customisable - additional tappings may be added or unwanted tappings delete from order. Additions and options may attract a small additional charge.

Additional tappings for solid fuel/AGA (gravity flow) heat input - Please add £20.00 per pair (flow & return)

Notes on F&E Tanks

All thermal stores require a Feed and Expansion tank (F&E) to facilitate thermal expansion, evaporation and system top-up. Existing tanks and other proprietary products may be suitable and therefore used. However, your strict attention is drawn to the suitability of any tank you plan to use in view of the temperature of water that could potentially reach it.

You should ensure the tank you intend to use can handle water at the temperatures associated with thermal stores, with special attention being paid to this issue if an uncontrollable heat source is connected (i.e. wood burning stove, AGA, Rayburn etc).

Horrific injury or death from scalding can result if an overflow scenario exists with a tank that distorts or sags when subjected to high temperature water.

Gledhill can supply two types of F&E tank (40 litre*) as an optional extra for use with the Torrent Greenheat thermal store. Both types are plastic and utilise plastics technologies suitable for their intended use.

Type 1 is suitable for use on a standard system where the heat source is regulated (e.g. gas or oil boiler controlled by thermostat).

Type 2 is suited for use with less controllable heat sources such as wood burning stoves or an AGA where heat from the source is unregulated.

*F&E tanks must be sized to take the water expansion of the whole system into account. (i.e. if additional system pipework connects directly to the cylinder the volume of the whole must be taken into account)
