| Efficient log burning boilers for home and commercial applications  "Home grown", carbon neutral and easy to store: wood is an attractive alternative to heating with oil or gas. This indigenous fuel is renewable and independent of fossil fuel reserves. Its combustion is CO2-neutral and therefore does not impact the atmosphere with environmentally damaging carbon dioxide emissions. Moreover, wood is available year-round, irrespective of the weather, and is easy to store. Burning wood in modern Viessmann combustion systems is efficient and environmentally clean. The Pyromat ECO developed by Viessmann Group member and wood combustion expert Köb offers new Ecotronic control for unsurpassed operating convenience when heating with wooden logs, wood briquettes and scrap wood. In contrast to the previous versions, the new programming unit of the Pyromat ECO has now been integrated into the boiler.The large, impact-resistant, graphics-capable display of the new Ecotronic control makes all information easy to read. The intuitive interface and multiple-line plain text display allow the various menus to be quickly navigated. Menu navigation is identical to the interface of Viessmann's compact gas, oil and heat pump units introduced at the 2009 ISH trade fair. All parameters are conveniently set via a scroll button, similar to many modern mobile phones. The new control can also be expanded via a bus to operate up to three mixer circuits or two mixer circuits and DHW. It is also compatible with accessories from the comprehensive Viessmann range of products. The Pyromat ECO can thus be combined with a solar thermal system or operated with a second boiler. The Pyromat ECO is available with outputs from 35 to 170 kW. It is particularly well-suited for buildings with higher heat demands such as two-family homes, apartment buildings and commercial premises. The large top-loading hopper (185 to 500 liters) can accommodate half-meter or meter-long logs depending on boiler size and allows combustion periods of roughly six to eight hours depending on wood type and boiler utilisation. Combustion in this unit is not sensitive to foreign materials such as screws and nails, which are often present in scrap wood. A lambda probe and a flue gas temperature sensor ensure efficient fuel combustion. They regulate the supply of combustion air via an induced draught fan, depending on the current wood gas/air ratio and the flue gas temperature. This allows the Pyromat ECO to achieve a boiler efficiency of up to 92%. Furthermore, the integral buffer heating management in Ecotronic control intelligently uses residual heat from the boiler water during the combustion phase, providing an incremental heat yield of up to 9 percent per burnout. The Pyromat ECO can also be operated with fuel oil. The addition of an oil burner is useful during longer absences, for example holidays, when manual loading of logs is not feasible. The necessary connections have been pre-installed. The Pyromat ECO comes fully wired with the return temperature raising unit pre-mounted on the boiler to save installation time and thus costs. write your comments about the article :: © 2012 Construction News :: home page |
