Gas condensing boiler (wall mounted) TopGas Modern gas condensing technology generates up to 15 % more heat from the consumed energy source.
TopGas. Advanced technology attractive and compact. TopGas. Advantages at a glance. TopGas wall-mounted boilers offer compact and advanced gas heating technology built to Exhaust gases cooled to around 45 C the high quality standards of Hoval. With its condensation technology, TopGas makes 15 % more efficient use of the energy source than modern low temperature boilers. Radiators TopGas wall-mounted boilers employ modern condensing technology. This principle recovers energy that would otherwise be lost with the exhaust escaping up the chimney, as is the case in conventional heating systems. Gas boiler Economical Save energy costs Compact, complete system 15 % greater efficiency and energy yield through advanced condensation design Minimum space requirements due to compact size Excellent fuel utilisation and significant electric power savings through needsoriented, modulating boiler operation Ideal for use in living areas due to very low operating noise Superior price-performance ratio due to Hoval quality workmanship Additional usable heat Heat exchangers In condensing technology, the hot steam contained in the exhaust is cooled to 40 50 C. As the steam condenses, the heat it contains is released. This additionally usable heat is returned to the heating system through heat exchangers. As a result, consumption, energy costs and emissions are reduced by around 15% compared to a low temperature boiler. Rapid installation due to intelligent, ready-to-connect complete system Ecological Easy to use Low in emissions and consumption First rate emission values due to optimised burner operating times and grid burner system Around 15 % lower energy consumption due to condensing technology and optimised burner operation Easy to combine with solar energy system to further improve eco-friendliness 2 Hot exhaust Sophisticated 15 % less energy consumption and emissions due to modern gas condensing technology Top quality Efficient heat transfer through premium heat exchangers Reliable and long lasting due to high quality materials and workmanship Comfort on demand Compact and discrete The modulating burner of the TopGas continuously adjusts its heat output to the heat demand, producing only as much heat as is needed. This reduces stand-by periods and high-energy, high- emission burner startups to around 10%. As a result, combustion is considerably cleaner, lower in emissions and consumes less energy. In addition, the burner service life is prolonged. The compact dimensions of TopGas wall-mounted boilers enable them to be installed anywhere with ease: in the heating basement, under the roof or even due to their quiet operation and unobtrusive design in living areas. Long service life and excellent energy yield Low emission grid burner system Quickly mounted and serviceoptimised The heat exchangers of the TopGas classic and comfort are made of high quality aluminium silicone on the exhaust side and copper on the water side. These materials provide excellent protection against corrosion. In addition, the thermal con ductivity of aluminium is ten times greater than that of stainless steel. In conjunction with the heat exchanger's special surface structure, these features optimise heat transfer and improve energy efficiency. The TopGas grid burner system additionally reduces emissions and thereby improves the already superb eco-friendliness of the TopGas unit. The patented grid burner achieves virtually flame-free combustion. The flat flame pattern stays markedly cooler than gas flames in conventional gas burners, significantly reducing nitrogen oxide and carbon monoxide emissions. TopGas wall-mounted boilers are delivered fully assembled and are quick and easy to mount due to a colour-coded connector system. All service-related components are conveniently accessible and can be readily exchanged when necessary. 3 4
