2 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.

5 The Andrews balanced flue models offer all the advantages of the established range of storage water heaters with the addition of balanced, sealed combustion flue system. This adaptable, concentric flue system draws all primary and secondary air from outside the building and provides solutions for those otherwise troublesome installations contaminated atmospheres, areas where air extract canopies cause problems and difficult flue runs. CSC models have a fan assisted flue. Features of Models RSC150 & RSC 190* Horizontal or vertical concentric flue kit included Hydrojet tank recirculation Room sealed flue system Optional Ancillaries Fully automatic control with BEMS interface Solenoid control kit Additional flue components Features of Models CSC 39, 59, 78 and 93 Horizontal or vertical concentric flue kit included Hydrojet tank recirculation Available for natural gas or LPG Fully automatic control BEMS interface (Natural gas models) Optional Ancillaries Additional flue components Balanced Flue Range RSC / CSC Each Water Heater is specified with the following horizontal or vertical flue components RSC Horizontal Flue 500mm flue piece 90º elbow 750mm terminal outlet with wall RSC Vertical Flue 1m vertical + 750mm terminal outlet. Additional flue components available (see price list) The following concentric flue components complete with heater connections are supplied with each water heater. CSC Horizontal models 90º elbow and horizontal flue terminal (approximately 0.9m long) complete with wallplate. CSC Vertical models Vertical flue terminal (approximately 0.8m long) A wide range of additional flue components are available ex stock from Andrews Water Heaters. *Maximum CSC horizontal or vertical flue length 7.0m, each 90º elbow reduces this distance by 1000mm. Before designing the installation for RSC models contact the Andrews sales office for an installation manual showing maximum flue length. *Note: On all flue installations, for distance over 1.5 metres we recommend that a condensate trap is fitted (see ancillary price list).

6 Options Storage tanks Mini-plate space heater ST Storage Tanks ST Storage Tanks Of similar construction but without burner and heat exchanger the ST storage tanks are complimentary to the water heaters where extra storage is required to satisfy heavy peak demands. Features Foamlock Insulation a full 2 of polyurethane foam exceeds the insulating value of 5 of 1 2 lb density fibreglass insulation and gives extra rigidity.

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.
