Stainless Lite is an unvented mains pressure store in Duplex Stainless Steel that establishes new criteria for quality, performance and life.

Providing powerful, mains-pressure performance, it incorporates high flow rate controls, ideal for multi bathroom homes, where baths fill very quickly, and flexible sitting options.

The Stainless Lite uses the very latest high specification Duplex to resist all forms of corrosion including crevice and stress whilst its high mechanical strength gives it the strength for long life. It is particularly light and easy to handle on site.

the gledhill connection

Gledhill have been at the forefront of the revolution that has taken place in recent years in the provision of domestic heating and hot water. making gledhill a natural partner to team up up with solaressence® to produce the most advanced solar systems on the market place.

We are both pro-active in the recycling of old copper cylinders in order to help reduce the impact of waste on the environment. all products have an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of either one or zero.

Full support to the benchmark scheme - the code of practice for the installation and commissioning of central heating systems. benchmark is designed to raise standards by placing responsibilities on both manufacturers and installers to ensure that consumers are provided with the correct equipment for their needs and that it is installed and commissioned in accordance with the manufacturer's instructions by competent persons. the objective is to improve the professionalism of the industry and raise levels of customer satisfaction.

Essence® Torrent ‘RE’ Solar

Mains pressure domestic hot water and central heating that is either open vented or sealed primary without the need for pressure & temperature relief valves, runaways to ground or annual safety checks.

Built on the expertise gained with our popular range of Torrent thermal stores, with models suitable for gas, electricity or oil, Torrent ‘RE’ Solar incorporates a highly effective heat exchanger to maximise the energy collected by the solar panels. These can be either flat plate or evaporated tube. The solar dedicated section of the Torrent ‘RE’ Solar then extracts this energy to provide hot water for domestic use but also, importantly, for heating.

Solar heated water flows through the boiler thus reducing the amount of fuel used for HEATING and hot water. This is particularly useful in Autumn and Spring when sufficient energy is still being produced through the collectors to provide background heating.

These flow rates are capable of providing a ‘power shower’ or filling a bath in 3-4 minutes.

Cold and hot water distribution design

Torrent ‘RE’ Solar models are designed to be fed directly from the mains. They fulfil the requirements of the Water Regulations and therefore do not require a check valve to be fitted to the supply pipe. The performance of the Torrent ‘RE’ Solar is directly related to the adequacy of the cold supply to the dwelling. This must be capable of providing for those services which could be required simultaneously and the maximum demand should be calculated. Torrent ‘RE’ Solar will operate at dynamic pressures as low as 1.5 bar (at the appliance) which must be available when local demand is at its maximum, but the preferred range is between 2 and 3.5 bar. As a general guideline, although a 15mm external service may be sufficient for the smaller dwelling with one bathroom, a 22mm service is preferred (25mm MDPE) and should be the minimum for larger dwellings.

Thermally advanced

It is not widely appreciated that uncased foam insulated cylinders can lose up to 40% of their insulation value within weeks of manufacture and can emit dangerous smoke if involved in a fire. Torrent ‘RE’ Solar uses safe, non-toxic non-combustible Rockwool for continuous high performance during the life of the unit. Heat loss is inline with the requirements of Part L for Thermal Stores as outlined in the WMA Specification for Thermal Stores.

Environmental

We are committed to minimising the environmental impact of our operations and work hard to comply with all relevant environmental legislation. We are pro-active in the recycling of old copper cylinders and can offer incentives to customers in order to help reduce the impact of waste on the environment. All our products have an Ozone Depletion Potential (ODP) of zero and a Global Warming Potential (GWP) of either one or zero.

Whatever the type of alternative energy chosen, the key to its success is the primary storage vessel and the control system. This is because all the inputs (whatever the source) and the outputs to both heating and hot water flow through a primary store.

Long life

The thermal store is manufactured from copper sheet to BSEN 1653:1998. The computer designed heat exchanger is produced from finned tube and incorporates a patented expansion chamber which is sealed for life. The units are tested hydraulically and pneumatically both during and after manufacture.

Essence® Sunspeed

Solar Essence® SunSpeed domestic hot water cylinders are designed for use with solar panels. The heat exchangers are purpose designed for this application because: -

( a) The primary flow temperature from these sources will normally be significantly lower than from conventional heat sources e.g. gas boilers. Therefore heat exchangers with large surfaces areas will be necessary to transfer the heat at low temperature differences.

(b) A second heat exchanger for conventional heat sources e.g. gas boilers will often be required. In this case the solar panel heat exchanger must be of a compact design and capable of being fitted very low down in the cylinder.

Performance
The ‘SunSpeed’ heat exchanger is designed to heat the cylinder water content from 10°C to 49°C in one hour with a constant primary flow temperature of 55°C.

The heat exchanger for use with conventional heat sources (e.g. a gas boiler) in SunSpeed 2 is rated to give the recovery time under 30 minutes as specified in BS1566.

Heat exchanger specification
The heat exchanger in a SunSpeed cylinder designed for SOLAR is manufactured from ‘Integron’ integrally finned copper tube and is only suitable for pumped circuits.

In a SunSpeed 2, the heat exchanger i.e. coil for use with a conventional heat source is manufactured in either 22mm or 28mm plain copper tube to meet the requirements of BS1566 and Part L of the Building Regulations.
