Torrent Greenheat SOL - solar thermal store


Gledhill Torrent Greenheat SOL thermal store

Solar compatible open vented thermal store with a vented or sealed heating output circuit




See the new generation of Torrent thermal stores -


TORRENT ECO-SOL replaces this model




Solar thermal store providing  mains pressure hot water compatible with open vented or sealed heating system

The Gledhill Torrent Greenheat SOL is designed for use with a 'wet' solar input heating the cylinder via a solar coil. Other heat sources may be added - both open vented (OV) and seal primary (SP) - by ordering the cylinder with the appropriate configuration of connections/heat exchangers.

Open vented appliances such as solid fuel/AGA/Wood Burner  require a set of direct tappings, whereas sealed primary requires the addition of a boiler coil. Both are optional, both must be specified.

A high-efficiency solar coil to allow the home owner to benefit from a wide variety of alternative energy inputs is included as standard.

If necessary, tappings may be positioned according to customer specifications, or removed if preferred. Tappings that are not immediately required can of course be sealed off for later use.

Torrent Greenheat SOL thermal store with solar input

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.

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)
