THE BOILER IS SUPPLIED WITH METHANE, FOR THE TRANSFORMATION TO LPG, CONTACT THE AUTHORIZED AREA ASSISTANCE CENTER IN ADVANCE Technical features Heat and DHW energy efficiency class (ErP) For heating and domestic hot water production Forced draft sealed chamber Declared load profile: L Nominal heat output: 24 kW Nominal heat input max. in heating: 25 kW Seasonal space heating energy efficiency: 88% Continuous sanitary production: 10.5 l/min Dimensions (Depth x Width x Height): 355 x 440 x 725 mm; 37kg Version: CNG CONDENSING 2000 W Condensation efficiency at the best value for money Condens 2000 W is a condensing boiler with instantaneous domestic hot water production, fueled by methane and convertible to LPG. The Condens 2000 W wall-mounted condensing gas boiler guarantees you the energy efficiency of condensing at an unbeatable price: with this boiler, savings start with the purchase and will also be evident in subsequent gas and electricity bills. Convenient from all points of view With an energy production of up to 25.6 kW, Condens 2000 W is the ideal efficient and convenient solution for single and two-family homes. This boiler is designed to last over time, thanks to the robust stainless steel lamellar bithermal heat exchanger and the 1:3 modulation range, which allows to reduce the number of times the burner starts, increasing the efficiency of the boiler and ensuring a longer life. To further reduce heating and domestic hot water production costs, Condens 2000 W is ready for integration with a solar system: thus, in addition to saving money, you are doing good for the environment. Simple and economical installation and maintenance Thanks to the compact dimensions of just 355x440x725 mm, the low weight (37 kg) and the 8-litre expansion tank on the heating side already integrated in the rear, Condens 2000 W can be installed very easily even in the smallest spaces. Thanks to the distance of the connections from the wall of 50 mm, installation is quick and easy. Boiler programming is also extremely easy, thanks to the intuitive LCD display, which shows all the necessary information and any codes in the event of malfunction, and the possibility of remote control via the TRZ 12-2 On/Off digital room chronothermostat. Advantages Wall-mounted condensing gas boiler in combined version for instantaneous production of domestic hot water, fueled by methane and convertible to LPG High domestic comfort: according to UNI EN 13203 for the production of domestic hot water Easy to install and maintain thanks to the casing composed of three parts: front cover, side panels and visible control panel Robustness and maximum use of energy, thanks to the integrated bithermal exchangers, the primary in stainless steel and the secondary recovery unit in aluminium-silicon alloy The power adapts to your real needs, thanks to the modulating gas valve/fan unit Very quiet operation with noise emissions below 36 dB(A) The ErP legislation and the new energy labels The future of heating systems Starting from 26 September 2015, in order to be placed on the market, heating and hot water production systems will have to comply with the ErP (Energy Related Products) regulations issued by the European Union. The ErP standards favor the eco-compatible design of products that consume energy from fossil fuels and have the aim of reducing energy consumption and CO2 emissions, as well as providing consumers with transparent and homogeneous information on the energy efficiency of the appliances, favoring their comparison. Regulations N 811/2013 and 812/2013 provide for a specific energy labeling of appliances for heating and domestic hot water production. Regulations N 813/2013 and 814/2013 prescribe, among other things, the minimum energy efficiency and pollutant emissions requirements that manufacturers of equipment for heating and domestic hot water production must comply with. These regulations therefore raise energy efficiency standards, improving system performance and excluding less performing technologies from the market. The energy label will be supplied by the manufacturer with the appliance and will represent concrete help for the consumer, allowing him to learn more about the characteristics of the system, acquire greater awareness of the energy savings allowed and make the best choice of what to buy. The energy label will provide information on the energy class of the product, on a scale between A++ and G, and on other additional notations, such as power and noise emissions. The ErP legislation provides for two types of labelling: the former is supplied by the manufacturer together with the product for heating and/or domestic hot water production appliances the second for systems composed of several elements. In this second case, the label indicates the levels of energy efficiency that can be reached thanks to all the components used, allowing the score attributed to each appliance to increase and increasing the energy class of the system: it is therefore the task of whoever makes/installs the system to supply the consumer the correct explanatory label. The ErP standards represent an opportunity to develop a market of highly efficient technologies, such as condensing, heat pumps, solar thermal, cogeneration and the integration of different energy sources in a single system. These technologies will have an impact on home consumption, approximately 80% of which is due to heating and the production of hot water, and are already being incentivized at a tax level today. Junkers Bosch is already in line with the dictates of the ErP legislation, demonstrating the future orientation that has always distinguished the brand.
