Alternative energy fuel sources are typically low grade, inherently unpredictable and are often available in plentiful supply but not when the heat energy is needed!

A thermal store provides the means to harness the energy when it is available for later conversion into both hot water AND heating.

Being open vented, they provide a simple and inherently safe way to produce high-performance mains pressure hot water. So the householder can enjoy the comfort and luxury of a mains pressure system produced from alternative energy sources.

The alternative energy feeds into the thermal store which is also the water that circulates around the heating system.

This means that the energy available from solar panels or a wood burning stove, for example, can be used to provide energy into the heating circuit to decrease the use of fossil fuel based boilers, and hence reduce household running costs.

It is very problematic and inherently unsafe to connect wood burning stoves or other uncontrolled heat sources to an unvented cylinder, and not easily possible to combine alternative energy heat sources to provide energy to the heating circuit, hence the unique advantages of a thermal store.

A Thermal Store at the heart of an alternative energy system

The Torrent MultiFuelStore is the ideal product to use as the heart of an alternative energy system as it will take energy input not only from a conventional boiler but also from a wide variety of alternative energy sources, including but not limited to:

• solar panels

• wood burning stoves and other uncontrolled heat sources

• ground or air source heat pumps

• electricity from renewable or low carbon sources

If the system is configured appropriately the heat from the alternative energy source will be available for both hot water AND heating. This is only possible with a thermal store such as the Torrent and is not possible with an unvented cylinder where you will only get an alternative energy contribution to the hot water.

A Thermal store with In-built upgrade potential

The Torrent range comes with a full array of tappings as standard so that, for example, a wood burning stove or solar panels can be added as an upgrade to the property at a later stage and the hot water cylinder will be ready to work with it.

Environmental credentials throughout

The Torrent range is insulated to a very high standard with our revolutionary Envirofoam insulation which has an Ozone Depletion potential (ODP) of zero and an industry leading low Global Warming Potential of 0.7. The insulation

incorporates Polyol which is derived from Rapeseed oil - a fully renewable resource. The 350 and 450 models are supplied in a blue flexible jacket and currently use Rockwool insulation which is a high performance insulation and also

HCFC free.

The Torrent thermal store range is manufactured from copper,

a fully recyclable resource, and made at one of our nationwide network of super depot manufacturing units local to the customer, meaning we are not shipping a heavy cylinder full of fresh air half way around the country! We think this makes perfect environmental sense and makes the Torrent the lowest carbon-footprint alternative energy cylinder available in the UK. They are also fully recyclable at the end of their extensive working life. In addition, where a copper cylinder is being replaced as part of the installation of a Torrent we are willing to take it back and provide a credit for the scrap copper which will then be recycled.

Legionella protection by design

Because the Torrent is a thermal store and the domestic hot water is heated via a heat exchanger (no stored domestic hot water) it has the added advantage of not needing any additional heating for legionella protection, which in a conventional or unvented cylinder would have to be provided by carbon-intensive electricity, which undermines the environmental benefits of an alternative energy installation, as well as significantly increasing the running costs!

Thermal stores are simple to install

As each product in the Torrent range is open vented there is no requirement for an unvented pressure and temperature relief discharge and the installer does not need to be specially qualified to fit it.

Thermal stores are compliant with Building Regulations

The Torrent range is Building Regulations Part L1 compliant for both new build and refurbishment projects. It is also fully compliant with the Hot Water Association (HWA) Performance Specification for Thermal Stores.

Water main requirements

The Torrent is a mains pressure hot water systems, therefore it is important to check and ensure that the performance of the incoming mains cold water supply is adequate before choosing to use it.

To achieve the best performance it is recommended that a dynamic pressure of between 2 and 4 bar is available at the appliance although it will work adequately at pressures as low as 1.5 bar.

A minimum flow rate of 30 litres/minute is recommended for small properties although in properties with more than 1 bathroom the required flow rate should be calculated using the method set out in British Standard BS6700 or other suitable design guide.

Torrent thermal stores are designed to be fed directly from your incoming water main.

They fulfil the requirements of Water Regulations and therefore do not require a check valve to be fitted to the supply pipe.

As with any other hot water appliance or combi-boiler the Building Regulation requirements for a suitable scale inhibitor to be fitted on the cold supply to the appliance if the hardness levels exceed 200ppm (mg/l) apply to the Torrent.

If the hardness levels exceed 300ppm (mg/l) an optional phosphate type scale inhibitor can be supplied along with the appliance.

Product selection

The model selection guide shown opposite will allow you to choose the model type that is suitable for the heating system and energy sources being used. Once you have done this refer to the section in this brochure dealing with each model type and also the installation manual for typical details including some system arrangement diagrams and the selection guide for the size of appliance you will need for a range of property types.

Although details of the most common energy supply and heating system options are shown there are so many possible combinations that it is not possible to show them all for each model type. If you have any queries we will be pleased to comment on any arrangements you are considering if you forward a detailed diagram outlining your proposals.

Full technical details including typical wiring diagrams are provided in the Torrent Design, Installation and Servicing Instructions. These must be read in conjunction with this guide and all installations must comply fully with their requirements as well as the appropriate Building regulations.
