G115WS Cast Iron Residential Oil Boiler - Buderus

G115WSA better way to heat your homeThe Buderus G115WS boiler is based on the highly successful G115, the World’sbest selling boiler. The G115WS has been redesigned and reengineered to extractand deliver more heat from every fuel dollar, and now has higher outputs at lesscost per BTU. Acknowledged as the leader in high-efficiency, low emission hydronicheating, Buderus offers innovative design and quality manufacturing with exceptionalefficiency and performance.A G115WS cast iron oil boiler is idealfor new installations or as a replacementfor virtually any make or model of boiler.They are compatible with most hotwater tanks. Constructed with superiormaterials and designed by the industry’sleading engineers, the G115WS boileris raising the standard for the industry.With two ETL approved venting options, either into a chimney or directly through thewall, the G115WS allows a wide range of installation possibilities.It’s nice having peace of mind when itcomes to my heating needs. Buderusgoes the extra mile with theirproducts, using meticulous standardsand top quality materials for yearsof reliable service. For example, allsections are tightly joined and sealedwith profiled, beveled steel pushnipples and use a patented GL180-Mflexible cast iron.”ComfortableKeeping your home comfortable and warm is a high priority—but it doesn’t haveto come at a high cost. Whether you heat by baseboard, panel radiators, hydro-airsystems or radiant flooring, our advanced heating systems will provide many yearsof exceptional comfort and economy. Unlike a conventional boiler which heatsand circulates water at only one temperature—typically 170° to 180° F and keepsheating and circulating this high temperature water until the thermostat signalsit to stop. A Buderus boiler, especially when paired with the Logamatic control,eliminates these room temperature swings by adjusting the boiler water temperatureto the current conditions, saving fuel while keeping you warm and comfortable.Special compounds provide agas-tight seal for safe and efficientoperation. And, thanks to theGL-180M cast iron’s amazingflexibility, this boiler resists thermalshock under conditions of rapidtemperature change.EfficientEnergy star ratings for boilers are based on an Annual Fuel Utilization Efficiency(AFUE) rating, which is a ratio of the heat produced to the energy consumed on anannual basis. Not only is the Buderus G115WS boiler Energy Star rated, but it isalso designed for ease of installation and maintenance. With features like a compactdimension and integrated handles for ease of transporting, adjustable leveling legs,rear tappings and flue connection, baffles and clips for adjusting stack temperaturesand a heavy gauge blue enameled jacket, a Buderus boiler is not only efficient, but itis easy to install.A full swing burner door, which can be hinged on either the left or the right, andfront access plugs which permit flushing of the boiler’s interior, allow the G115WSto be thoroughly and properly cleaned in a fraction of the time it takes to clean aconventional boiler.The full swing burner door on thecombustion chamber allows foreasy, thorough and proper cleaningin a fraction of the time it takes toclean a conventional boiler.

G115WSCast Iron Residential Oil BoilerIntelligent Heating—By DesignThe G115WS is designed in Europe where fuel costs are significantly higherand environmental regulations are more stringent. Using state of the art techniques inthe design and manufacturing process, the G115WS is built to maximize the heatingvalue of every ounce of fuel and constructed with the highest quality materials.Manufactured without a heat-consuming refractory or target wall, service andmaintenance calls are minimized, while fuel efficiency and heat transfer ismaximized. The patented Buderus GL-180M flexible cast iron ensures that theboiler resists thermal shock under conditions of rapid temperature change. Sectionsare securely joined together and sealed by profiled, beveled steel push nipples,ensuring a long life with no leakage. Special compounds provide a gas-tight sealfor safe and efficient operation. The full 3” thermal insulation around the boiler,including underneath, increases efficiency by almost eliminating standby and stacktemperature losses.Buderus, the World leader in heating technology, manufactures the highest qualityboilers based on centuries of experience. With its innovative design and qualitymanufacturing, a Buderus boiler will outlast and out-perform virtually any otherresidential hot-water system in the world.Complete your system for added comfort to your home!Once you have a Buderus boiler you can add a Buderus indirect fired hot water tank,an optional Buderus Logamatic control or both. The Logamatic control maximizesyour comfort and fuel savings, it will also accommodate specialized heatingapplications such as radiant flooring. Combined, this premium heating system willprovide years of exceptional comfort and economy... for little more than cost of astandard replacement components.Domestic Hot Water TanksNeed domestic hot water? Then combine your Buderus boilerwith a Buderus indirect hot water tank. A Buderus tank is sowell insulated that it loses less than ¼º per hour. Available in avertical, or a horizontal space saving model that installs under theboiler, these tanks have a higher recovery rate than stand aloneor tankless coil models. While a Buderus boiler works great withany hot water tank—you can be sure of increased boiler efficiency,system longevity, and minimized service calls when you insist on aBuderus tank and boiler.The Three-Pass Boileris Designed for❚ Optimized combustion with positivepressure-fired boilers and tailoredchamber geometry — no need for aheat-consuming refractory or target walleliminating the need for costly repairs.❚ Minimal stack losses with themodified three-pass flue design’slarge heat transfer areas.❚ Low standby losses with a full 3½" to4" jacket of thermal insulation aroundthe entire block — even underneaththe boiler!How It WorksThe flame fires into the first chamber.Then the flue products flow throughthe second pass to the front of theboiler. From there they reverse directionagain—moving through the third pass tothe back, and finally exiting via the flueconnection into the chimney. Becausethe gases are held in the boiler longerthis allows the cast iron to absorb themaximum amount of heat, resulting ina lower stack temperature and ahigher efficiency.Convenient Logamatic ControlAdding a Buderus Logamatic control will give you theultimate in comfort and fuel savings. Microprocessor-basedcontrols allow the Logamatic to intelligently manage both your home heating anddomestic hot water. The Logamatic has 16 standard functions including day/nightsetback, automatic summer/winter changeover and even a vacation mode. Set itonce and relax in the comfort of your warm home.
