The Torrent ECO is a superior quality Thermal Store. Thermal stores are the inherently safe way to produce mains pressure hot water without the dangers associated with their counterpart - the unvented cylinder.

A thermal store provides the perfect solution to a homes heating and hot water requirements. Torrent ECO offers more options than any other store or cylinder, and is designed to reduce heating costs by offering complete flexibility for householders to use multiple energy sources.


Apart from being safe, thermal stores have several other advantages. Possibly the most notable is the fact that a thermal store can safely accept thermal energy from just about any heat source whether it be controllable or uncontrollable. For example:

  • Conventional boiler systems (gas or oil)

  • Solar panels

  • Wood burning stoves & back boilers (or other uncontrollable heat sources)

  • Gravity or pumped heat sources

  • Heat recovery systems (Ground source & Air source)

  • Electricity (from grid or renewable sources)

Other advantages include:

  • Being inherently safe being an open vented cylinder

  • No G3 requirements for installation

  • No discharge pipework

  • No annual maintenance or safety check requirement


So what's new with the NEW Torrent ECO?

With the new Energy-related Products (ErP) Directive for hot water cylinders in mind, the new Torrent ECO range has not only improved the benefits of the Torrent, but also added some fantastic new features to provide the home owner a immensely energy efficient thermal store.

  • Energy saving with a high efficiency ErP ready pump

  • Flow sensor providing a 75% reduction of hot water response times

  • Improved PCB and software

  • Higher store temperatures can be utilised, providing greater benefit from solid fuel inputs

  • Secondary return functionality (optional kit available if required)


A thermal store is inherently safe

The simple fact is a thermal store remains open vented and as such cannot suffer from dangerous 'over pressure' scenarios that could lead to explosion as with an unvented cylinder. Heat sources that cannot be regulated such as wood burning stoves (deemed uncontrollable) can safely supply heat to a thermal store - something you are prohibited from doing with an unvented cylinder.

When you look at the multitude of heat sources that are commonly available and consider that the energy from each may be harnessed safely by a single device, giving back in the form of heating and/or hot water, you can begin to appreciate the unique value of the Thermal Store.

Advantages don't stop there. When appropriately incorporated into a heating system a thermal store can pass heat accumulated from all alternative energy sources to the central heating system - a feature only possible with a thermal store. So now, for example, your stove can heat your entire home, not just the room in which it sits.

Mains pressure hot water from a Torrent ECO

The fundamental task of a Torrent ECO thermal store is to provide mains pressure hot water safely. One might however look beyond the comfort of a safe and vented appliance to its operation. The environmental credentials of the Torrent ECO are impressive.

Torrent ECO is insulated to a very high specification with an industry leading Ozone Depletion Potential (ODP) and global warming potential of ZERO.

Domestic hot water (DHW) is generated via a highly efficient plate heat exchanger through which cold water is generated instantaneously upon demand. This method completely removes the risk of Legionella and has the potential to produce impressive flow rates of up to 35 litre/min.

Torrent ECO is available in five different models.

To facilitate use on a multitude of system configurations the Torrent ECO is available in five distinct models, each of which are available in a range of sizes.
