Gas Storage Water Heaters CONVENTIONAL FLUE FAN FLUED BALANCED FLUE DIRECT STORAGE TANKS
Andrews Storage Water Heaters For the continuous production of hot water in domestic, commercial and industrial applications Andrews Storage Water Heaters are the perfect answer. Efficiency and economy of operation are achieved by separating the hot water generation from the space heating requirement. The heaters can be sized to accommodate specific applications and in many instances, located close to the point of use eliminating transmission losses and reducing installation and running costs. For applications where there is a constant demand for hot water or where demand peaks at specific times the fast recovery rates guarantee hot water when needed. Of particular significance to the healthcare sector, Andrews Storage Water Heaters eliminate the conditions that allow legionellae to be present. The extensive range comprises eleven models with recovery rates from 160 to approximately 1800 litres per hour at 50ºC rise. General features of all models (Additional features are shown for each range) CE approved to European Water Heater Standard EN89.

This provides a tough interior surface for storage tanks, which must withstand the wearing effects of high volume and high temperature hot water. Factory installed dielectric nipples no dielectric fittings or unions needed. Two magnesium anode rods for more even distribution of corrosion protection and longer service life. Hand hole clean-out for removal of accumulated lime and sediment deposits. Solid brass drain valve Steel tank heavy gauge steel automatically formed, rolled and welded to assure a continuous seam or vitreous enamel lining. Each tank is triple tested to ensure quality. Mini-Plate space heating package When the heating demand is small but high volume hot water is required the combination of an Andrews MiniPlate and an Andrews Water Heater provides the complete solution. A plate heat exchanger, pumps and electronic control assembly neatly packaged inside a compact enclosure provide an add-on space heating function for Andrews Water Heaters.
