Gledhill Torrent Greenheat HP thermal store

With a Torrent Greenheat there are no health issues because the water is being heated indirectly and the lack of a heat exchanger/coil for the heat pump means that the full output is delivered to the store, both of which ensure that less boost is required to achieve an acceptable hot water temperature at the tap.

In fact, the ease with which renewable energy sources, such as wood burning stoves, can be connected to a Torrent Greenheat store means that these are often chosen to provide the boost in preference to electrical heaters.

However, separate immersion heaters can be fitted to boost both the central heating and the domestic hot water sections of the thermal store.

Additional tappings for heat inputs such as a wood burner and/or solid fuel stove can be added if required at a small extra cost.

It is worth remembering the lower temperatures delivered by a heat pump also means that radiators need to be sized to take account of this, or an underfloor heating system that operates at temperatures that can be achieved by the heat pump being used.

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)
