5 Delivering Quality nsuring excellence through our process. ThermaQ range is the first choice for value while providing superior performance. How do we guarantee our customers the best possible performance, quality and reliability from our products, whilst ensuring our system provides powerful mains pressure for showers and faster-filling baths, with maximum reliability and efficiency? The answer is in our process. When developing the ThermaQ range of products we set about using the most advanced water heating technology available. When this doesn t meet the high standards of performance, efficiency and reliability we insist upon, we develop innovative new technology of our own. These advances come in many forms; Sophisticated Duplex stainless steel cylinder construction for maximum strength and corrosion resistance, manufacturing the cylinder by robots for efficiency and technical accuracy, CFC and HCFC free injected foam, encasing the entire system for the best possible heat retention. To prove our confidence in this process, we provide every new cylinder with a 25 year guarantee* against manufacturing defects. Manufacturing our Cylinders ThermaQ manufacture all our domestic cylinders using Duplex stainless steel. Duplex has been selected against other materials such as copper, glass lined mild steel and lesser grades of stainless steel due to its substantially higher tensile strength and because it is a low carbon, high chromium content alloy. It allows units to be produced using thinner walls resulting in a lighter unit and offers a superior resistance to all forms of corrosion including, pitting, crevice corrosion and stress corrosion cracking. When welding our cylinders a backing gas is used to ensure deep welding penetration and a clean internal weld surface. This ensures the welded area has the same corrosion resistance and mechanical strength as the parent metal. Once the welding process has been completed the cylinder is pickled and passivated, this involves coating all internal surfaces of the cylinder with a chemical solution followed by water flushing, restoring the chromium surface finish. This process restores the passive film to all welded areas providing protection against premature corrosion, ensuring the longest possible working life for every cylinder. Installer friendly design. Standard units available from litres. Bespoke units manufactured to your own design. Full range of slim units available, 60L to 210L, featuring a diameter of only 475mm one of the slimmest on the market. A range of horizontal cased units. High performance coil-in-coil heat exchanger manufactured by ThermaQ. xternal expansion for reliability and flexible locations. Full NSF-WRc product approval. Vessel constructed from Duplex stainless steel for maximum strength and fully pressure tested. Totally insulated with 50mm HCFC & CFC free foam. Comprehensive controls and fixing kit from leading manufacturers. All cylinder connections are 22mm compression. Minimum water supply 1.5 Bar, 20 Litres/ Min. Stainless steel stat pocket guaranteed against corrosion. All units are pickled and passivated to ensure longer life. 25 year fully transferable warranty*. All other cylinder components guaranteed for 2 years. Our coil-in-coil heat exchanger is a technical triumph. Manufactured in-house from one single piece of stainless steel tube, this high efficiency heat exchanger allows the cylinder to heat all the way to the bottom of the cylinder. * See page 17 for guarantee details. thermaq specification hotline

16 ThermaQ has made significant investment in the latest manufacturing technology and systems to develop robust and automated processes that ensure we produce the best product at the best value. Installation Our product guidance. Regulations ThermaQ is covered by Section G3 of the Building Regulations (ngland and Wales), Technical Standard P3 (Scotland) and Building Regulations P5 (Northern Ireland). All Unvented units with a capacity over 15ltr must be installed by a competent installer in accordance with these regulations. Mains Supply The unvented cylinder needs a minimum of 1.5 bar (max 10 bar) mains pressure and 20 litres a minute flow rate to ensure that the cylinder meets its minimum capabilities. Higher mains pressure and flow rates will result in a higher performance from the cylinder. Cylinder Siting With no header tanks to consider, ThermaQ units can be sited almost anywhere in the house. can supply outlets both above and below its location and must be fitted on a flat surface capable of holding its full weight. (Refer to installation instructions supplied with cylinder). Boiler Compatibility Any appliance that is fitted with an integral control thermostat and Its own energy cut-out (these include natural gas, lpg, electric and oil boilers). Solid fuel appliances such as Aga, Rayburn, etc., without full thermostatic control cannot usually be installed with an unvented unit. Please consult the installation guide for further information. Secondary Return Connection As standard 210, 250 and 300 litre models are fitted with a secondary hot water tapping. Other sizes can be fitted with a secondary return if required. Wiring All electrical wiring should be carried out by a competent electrician and be in accordance with the control scheme being used and the latest I regulations. The controls provided with the will ensure the safe operation of the unit within a central heating system. The is compatible with Y, S and S plan plus layouts. xternal wiring to the immersion heaters must comply with the relevant I wiring regulations and the circuit must be protected by a suitable fuse and a double pole isolating switch.

Please contact thermaq for technical support. Using ThermaQ units in Series A popular option is, instead of having one large cylinder, to have two small cylinders installed, as a possible solution to limited space in a cupboard. The method of installing cylinders in series is so that the cold mains feeds the first cylinder, and the hot draw off from the first cylinder provides the feed for the second tank. The second tanks hot draw off then provides the hot supply for the property. The supplied combination valve will be installed on the mains inlet to the first cylinder and this is also where expansion vessel for both cylinders are connected. We recommend the use of ThermaQ calorifiers for large domestic or commercial applications, however when space is of a premium it is possible to connect smaller cylinders in series or parallel to achieve the quantity and flow required. Using ThermaQ units in Parallel For situations when very high flow rates or larger volumes of hot water storage are needed, units of two or more can be linked in parallel. When connecting two units in parallel, individual cold feeds are taken to each cylinder and then hot draw offs are connected together. Subject to the size of the incoming cold mains the flow rate available effectively doubles.
