Megaflo eco Unvented hot water cylinders

Megaflo eco. etter for you, your customers and your environment. Our Megaflo eco range is the best choice for conserving energy while providing superior performance. How do we guarantee our customers needs the best possible performance, quality and reliability when developing unvented water heating systems? How do we ensure our system provides powerful mains pressure showers and fasterfilling baths and with maximum reliability and efficiency? The answer is simple. We use only the most advanced unvented water heating technology available. nd, where this doesn t meet the standards of performance, efficiency and reliability we insist upon, we develop innovative new technologies of our own to bridge the gap. These advances can come in many forms. Sophisticated Duplex stainless steel cylinder construction for maximum strength and corrosion resistance; CFC / HCFCfree injected foam, encasing the entire system including the bosses and valves, for the best possible heat insulation; a floating baffle system to replace a conventional external expansion vessel for quicker and simpler installation. nd to prove our confidence in this advanced new technology, we provide every new system with a lifetime cylinder guarantee with onsite service support. Then we detail precisely what sets the Megaflo eco apart from everything else Installerfriendly design. Fully indemnified design service. Improved performance at low pressures down to bar. New water inlet controls increase flow rates by up to 0%. Improved insulation for maximum heat retention. Reduction in heat loss of up to 7%. No anode eliminates costly anode maintenance. Insulated casing for the temperature and pressure relief valve to minimise heat loss. Unique Lshaped longlife Superloy immersion heater reaches deeper into the tank giving more hot water. Titanium immersions as standard on all direct models. Patented cold water inlet diffuser minimises mixing of cold and hot water. High performance coilincoil heat exchanger. Exceeds CHeSS * est Practice for recovery times and insulation. Complies with future Energy Related Products Directive. Constructed in Duplex stainless steel for maximum strength pressure tested to 5 bar. Compatible with a wide range of UK solar systems.

Innovative technology For domestic and commercial applications Cylinder construction Duplex stainless steel offers a superior resistance to corrosion especially in aggressive water areas, compared with some grades of stainless steel, glasslined steel and copper. ecause Duplex is a low carbon, high chromium content alloy, it resists all forms of corrosion including pitting, crevice corrosion, uniform corrosion and stress corrosion cracking without the use of a sacrificial anode. In addition, the tungsten inert gas welding coupled with the special postweld processes ensures the welded area has the same level of corrosion resistance and mechanical strength as the parent metal. This ensures the longest possible working life for every cylinder. Internal air gap and floating baffle The internal air gap and floating baffle system allows for a compact selfcontained unit which eliminates the need for an external expansion vessel and allows for a quicker and simplified installation. Expanded water is accommodated within the cylinder using an internal air gap maintained by a patented floating baffle. This baffle floats on the surface of the water within the cylinder to maintain the integrity of the air gap. efore expansion fter expansion Floating baffle The combination of its lightweight yet very strong construction makes Megaflo eco easier to handle onsite. Every unit is pressure tested in the factory to 5 bar five times the normal operating pressure making Megaflo eco suitable for all domestic and commercial applications. No sacrificial anode is required with Megaflo eco. With inferior grades of stainless steel, glasslined steel and copper, sacrificial anodes are required to achieve a degree of corrosion resistance. However they require regular replacement which, if not carried out can result in premature cylinder failure. Megaflo eco overcomes any need for this by using top quality Duplex stainless steel.

System benefits In addition to the performance benefits of fast filling baths and powerful showers, unvented hot water systems offer many features and benefits over other types of hot water systems. Flexible siting Unlike traditional vented systems, there is no requirement for a cistern tank in the loft, giving users a quiet hot water system. Installation locations are also flexible, so the cylinder can be installed in an airing cupboard, loft, cellar, utility room or even in a garage.

Megaflo eco solar pplications and installation Which unit to use The choice of capacity for traditional cylinders is based on the hot water requirements of the dwelling. With solar cylinders the usable hot water will vary due to a number of factors such as siting of solar panels, time of year and weather conditions. For this reason, when choosing a solar cylinder you should ensure that sufficient usable hot water will be available during winter months where solar gain is at its lowest.
