The Gledhill TORRENT Heat Store


TORRENT and TORRENT RE thermal stores from Gledhill
 

The most exciting product development in the field of mains pressure hot water for years.

Thermal stores (otherwise known as Heat Stores) are fast becoming the preferred option in the field of mains pressure hot water to the complications and hazards of an unvented hot water cylinder. Building Regulations in the United Kingdom states: Any vessel storing more than 15 litres of hot water under pressure is subject to section G3. This means virtually ALL unvented cylinders, but not so the TORRENT. Because the bulk of water in the Torrent heat store is vented to atmosphere it present no danger and is therefore exempt of regulation. And this is as it should be. The water in a Torrent cylinder is used to store energy in the form of heat, nothing else. The clever part is what the cylinder does with its energy.

Torrent Cylinders are available as the following models -

  • TORRENT Indirect - a vented thermal store obtaining energy from a boiler. This model is ideally suited to the typical household offering the added benefit of easy upgrade to a mains pressure system during refurbishment. For more information choose from the options below.

  • TORRENT Direct - an electrically heated model with two immersion heaters. Typically used in conjunction with an economy tariff electricity supply. For more information choose from the options below.

  • TORRENT RE - An advanced vented thermal store providing mains pressure hot water with multiple input capability from SOLAR, WOOD BURNER, BOILER, GROUND SOURCE or AIR RECOVERY and AGA and the facility of running central heating directly from the store. CLICK for more on the RE Model

So what is a Thermal Store?
A Thermal Store is a vessel which acts like a battery for heat. Mains pressure cold water enters a heat exchanger within the store where stockpiled energy in the form of heat is quickly transferred directly to the incoming water supply. Mains pressure hot water exits the cylinder via the heat exchanger never mixing with the contents, hence the cylinder remains vented to atmosphere. This is what makes a Thermal Store inherently safe.

 

Open vented - highly insulated, efficient and most importantly - SAFE. Because the TORRENT does not store more than 15 litres of hot water under pressure it is exempt G3 Building Regs (UK) which means you do not need Building Regulations Approval to install one, certification by the installer or annual maintenance.

Easy to install - the TORRENT can be fitted simply into existing systems, including the existing boiler and controls, where appropriate. Can be fitted without specialist certification.

Does not require - expensive safety controls or temperature and pressure relief pipework to outside.

No need - for external expansion vessels - and wiring is the same as any traditional Y, S or W plan system.

Long Life - the TORRENT is manufactured from copper sheet to BS2870. The computer designed heat exchangers are produced from finned tube and incorporate a patented expansion chamber which is sealed for life.

Economical to install - No specialist fitters required to install a Torrent. Inherently safe by nature you won't be needing to pay premium prices to your installer.
