Services to match the heating system Modern heating systems are packed with sophisticated techno- logy and complex electronics. Particularly in commercial and public buildings, it is essential to have a system with a full ser- vice history. The failure of the heating system can have dire con- sequences in these buildings, resulting in production losses, rent cuts and action for damages. Schools and hospitals also need to be able to rely on trouble-free operation. For this reason, ELCO offers the right services to match each heating system and every requirement. From the professional commissioning, to the routine maintenance through to servicing and reliability checks over many years. Assure yourself long-term functional reliability and cost certainty with an ELCO service agreement.

This is approx. 14 kW per m² greater output than a comparable boiler that also almost weighs twice as much, with far bigger dimensions. The modulating, water- cooled premix burner ensures maximum combustion efficiency – and what is more with extremely low NOx emission values of just 11.5 mg/kWh, i.e. significantly below the BREEAM standard. The heat exchangers, fully equipped with stainless steel compo- nents, increase the durability and service life of the RENDAMAX 3400/RENDAMAX 3600 SB series. The modulating premix burners with innovative water cooling excel with their precision controll- ability coupled with high efficiency and clean combustion processes. Thanks to rated output ranges of 660 kW to 1.9 MW and the option of connecting up to 8 boilers in cascade, the RENDAMAX 3400/RENDAMAX 3600 SB gas condensing boilers are ideal for use in commercial buildings, such as office blocks, schools, shopping centres, hotels, residential buildings and district heating plants. New building: Watermark Place, London ELCO gas condensing boilers utterly convincing There are various rating systems and certificates governing the sustainability of buildings. BREEAM (Building Research Establishment Environmental Assessment Method) is the most widely used certification system, which was comprehensively updated in 2008. In eight assessment categories, BREEAM awards a seal of quality in four grades: excellent, very good, good or average. The criteria take account of effects on global, regional, local and in- door level. To date, over 100,000 buildings have been certified and over 500,000 registered in accordance with BREEAM.
