Hot and Cold Water Systems

Hot and cold water systems have changed very little of the last 100 years. Traditional systems store cold water in storage tanks feeding a hot water cylinder that would be heated by electric immersion or via a boiler heated by solid fuel, oil or gas.

With the introduction of power showers in the early eighties out traditional hot water systems started to change to accommodate our demands and needs. The bathroom has now become one of the most important rooms in the house. Spending time to make sure you have the right system to support your hot water needs is extremely important, get it wrong and you can be left disappointed with a system that under performs, and doesn’t meet your demands and expectations.

With our many years of experience in the industry we can offer the right solution for your needs supported by knowledgeable staff to discuss all your hot and cold water requirements. We offer simple advice on traditional systems with shower pumps; combination boilers and modern mains pressure systems.

Unvented cylinders are now the preferred choice for many developers, heating engineers, architects and end users, with many benefits over traditional systems

An unvented cylinder is a storage water heater sealed to the atmosphere that is connected directly to the mains water supply, delivering mains pressured hot and potable cold water to all outlets. Unvented cylinders are quiet in operation, have quicker heat up and recovery times. Made to a high specification the cylinders also allow for greater choice in bathroom and shower fittings.

• Choice of quality unvented cylinders to suite your needs
• Direct and indirect cylinders available
• Range of Solar cylinders for use with Renewable energies
• Finance options available

Introducing Dualstream Systems:

Standard unvented cylinders are totally reliant on the main supply, for both pressure and flow rate. A poor main supply will cause pressure and flow fluctuations, poor performance and ultimately customer dissatisfaction.

Dualstream systems are a combination of a stainless steel unvented cylinder and accumulator technology and have been designed to over come poor flow rates, and maximise performance. Using accumulator technology to help boost mains supplies is something GAH have been doing for over 9 years with a proven track record within the industry. Surab Ltd has been working with GAH promoting accumulator technology for many years, with many satisfied customers.

Accumulator technology how does it work

The accumulator is a vessel with a controlled action diaphragm that can hold mains pressured water. The accumulator is installed on the incoming main supply and the diaphragm starts to fill with water. The diaphragm is surrounded by a positive air charge that forces the water in to the supply chain feeding outlets, increasing volume and stabilizing pressures. Simple and extremely effective in over coming flow rate issues and without requiring a power supply or drainage requirements and no expensive running costs.

• Will provide a substantial increase in water volume, to both hot and cold-water outlets, with-in the building. Will work at very low flow rates (9LPM) 1.5 Bar
• Balanced hot and cold water supplies, giving wider choice of Taps and mixers
• Designed to work on 15mm shared main supplies and Overcomes problems associated with low-fluctuating mains pressure or inadequate flow rates
• Models designed for small flats, large properties and light commercial, Accumulators and cylinders can be linked together for greater demands, for the larger properties, small Hotels and Leisure and Sports Clubs
• Indirect Models from 125 -500-litres (heated from a Boiler source) Direct Models from 125-500 litres (heated from Electric Immersion) Twin Coil Cylinders for use with Solar Energy or other heating source 210-300-litres
• Accumulator models from 100- 500
• Dualstream systems covered by Patent Number GB 2349908 and WRAS number 0109003

Accumulators can be used to increase flow rates to mains fed appliances such as combination boilers and existing unvented cylinders with the guidance and approval of GAH and Surab Ltd.
