Lochinvar Lochinvar as fired storage water heaters Knight water heaters Traditionally hot water systems in coercial and industrial buildings have been supplied indirectly by heating boilers and indirect cylinders - also referred to as calorifiers. This type of system had many operating and logistical inefficiencies especially during the suer months when the main heating boiler was required to run in order to deliver only the buildings hot water requirements. number of overnment sponsored energy saving campaigns have promoted system separation and de-centralization of the heating and hot water plant, a philosophy for which direct gas fired storage water heaters are ideally suited. The design principles of Lochinvar Knight and harger water heaters are based upon low storage capacity and fast recovery times. This means the water heaters can be sized to suit each individual application and sited close to the point of demand helping to reduce transmission losses and installation costs and enabling increased operating efficiencies and a reduction in energy usage. namelled vessel for extended operating life affled flueway for maximum heat transfer igh level of insulation minimises standing heat loss ustom designed steel baffles suspended in the flueways increase the amount of heat transfer from the flue gases. layer of cfc-free polyurethane foam envelops the storage vessel reducing standing heat losses to an absolute minimum, whilst further insulation encapsulates the combustion chamber, ensuring maximum heat transfer from the burner into the water vessel. This ÔscrubbingÕ action helps to achieve fast recovery of hot water. ll Knight water heaters have a single baffled flueway, harger models have between 5 and 7 baffled flueways increasing the heat surface area by up to 35. t the heart of both ranges is a heavy gauge welded steel vessel. The vessel is lined internally with a vitreous enamelled material, protecting it from any corrosive elements in the water and ensuring the water remains contaminant free. hoice of 7 models for specifying flexibility There are 7 models available in the Knight range, 5 of which have permanent pilot and 2 with automatic ignition. Storage capacities range from 09 to s and recovery rates from 27 to s/hour (based upon a temperature rise of 50) are achievable. ll Knight models are available for Natural as or LP. harger water heaters Knight features igh outputs harger features Vitreous enamel lined storage vessel free foam insulation - reduces standing losses Suitable for unvented and open vented installation vailable for Natural as or LP Lochinvar harger water heaters incorporate multiple flue tubes rising vertically through the water vessel. This allows for higher rated burners to be used enabling faster heat up times and larger volumes of hot water to be available.

The Knight L75, L75, L5 and L5 models incorporate one 00 clean out access point. There are 5 models available across the harger range, 7 of which have permanent pilot and having automatic ignition. Storage capacities range from 252 to 357 s and recovery rates from 44 to 53 s/hour (based upon a temperature rise of 50 ) are achievable. ll harger models are available for Natural as or LP. Note: lean out access only available on models L75 and L5 The lining has a coefficient of expansion similar to that of the vessel itself and therefore is not subjected to any stresses that could cause fracturing. itted as standard, magnesium sacrificial anodes prolong vessel life and inhibit corrosion. n alternative method of protection is available in the form of orrex non sacrificial electrical anodes. These are available as an ancillary option.
