Domestic hot plate heat exchanger for condensing also in DHW. 6 liter heating expansion tanks. Circulator in Energy Class A. The ErP legislation and the new energy labels The future of heating systems Starting from 26 September 2015, heating and hot water production systems must comply with the ErP (Energy Related Products) regulations issued by the European Union in order to be placed on the market. 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 appliances, favoring comparisons. Regulations N 811/2013 and 812/2013 provide for a specific energy labeling of appliances for heating and the production of domestic hot water. 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 underperforming technologies from the market. The energy label will be supplied by the manufacturer with the appliance and will represent a concrete aid for the consumer, allowing him to better understand the characteristics of the system, acquire greater awareness of energy saving, and allow him to choose better 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 for an increase in the score attributed to each appliance and increasing the energy class of the system: therefore, the task of whoever builds/installs the system is to provide the consumer with 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 consumption in the home, approximately 80% of which is due to heating and the production of hot water, and are now tax-incentivized. Junkers Bosch, already in line with the dictates of the ErP legislation, represent a future that has always distinguished the brand. Warranty: All products for sale on our site are new and packed.

AVAILABLE TO ORDER GAS BOILER IMMERGAS VICTRIX 28 KW TT METHANE CONDENSATION Immergas Victrix 28 KW TT condensing boiler Capacity: 28Kw Useful heating power kW : 24.0 DHW useful power kW: 28.0 Type: snapshot Modulation range: 11 - 100 % Hot water production (∆t 30 °C) l/min: 13.4 Electrical protection degree IPX: 5D Power supply: methane VICTRIX TT The VICTRIX TT ErP range, intended for new installations and above all for the replacement of existing appliances, has been designed to comply with the new European Directives on the use of energy, increasingly oriented towards condensing technology to more easily reach the efficiency classes high in space heating and in the production of domestic hot water in homes. VICTRIX TT ErP, produced in the new highly automated lines of the company's historic headquarters in Brescello, incorporates the innovative condensing module which guarantees high flow rate and head on the heating circuit, low risk of clogging due to any impurities in the system and greater corrosion resistance thanks to the special alloy with which it is made. Reduced consumption thanks to the class A circulator and boiler power modulation up to 15%: ideal condition for mid-seasons or reduced loads. In addition to a very low environmental impact, the boiler features an advanced and easy-to-use user interface with adjustment knobs, selection buttons and LCD display for viewing operating temperatures, operating status and error codes. HIGH HYDRAULIC PERFORMANCE The condensing module has been designed to have large water passages which allow interesting flow rate and head performance even on old heating systems. This also means a low risk of clogging in the presence of impurities in the system water. It is made of a special Aluminium-Silicon-Magnesium alloy, a material which – together with the high thicknesses used – is particularly resistant to corrosion. The water circuit runs through the exchanger in an ascending manner, in counter-current with respect to the flame. The dense pinning allows you to increase the exchange surface ensuring excellent water yield. It is important to keep the pH of the heating system filling water between 6.5 and 8.5 with a hardness of 15°F (ref. UNI 8065 - DI 26/06/15). CLASS A CIRCULATOR The low-consumption modulating circulator guarantees considerable savings in electricity compared to a traditional circulator, it can be set in Auto or Fixed operating modes. WIDE MODULATION RANGE The electronic card reduces operating costs thanks to particularly high yields even with low energy absorption, as occurs for example in the mid-seasons. In fact, the wide range of modulation of the appliance (from 15% to 100% of the thermal power) determines high seasonal yields. LOW ELECTRICITY CONSUMPTION IN STAND-BY (LESS THAN 6 W) EVOLVED DESIGN The VICTRIX TT ErP range is designed to make the work of professionals easier. Immergas has invested significant resources in the industrialization of the parts of the appliance, making it particularly robust and has paid the utmost attention to details and finishes. VICTRIX TT ErP presents new technical features such as: • safety valve drain conveyed to the condensate drain • removable cover for direct access to the electrical connection compartment • cover casing for the water connections to better position the boiler in domestic spaces DIRECT ACCESSIBILITY TO THE ELECTRICAL CONNECTIONS COMPARTMENT In the lower part of the boiler there is a connection compartment accessible without the need to open the product but simply by removing the aesthetic cover, to house the electrical connections of the main devices that can be combined (for example CARV2, external probe, CRONO 7). ELECTRONIC AIR/GAS CONTROL The electronic gas valve allows air/gas control by means of a multifunction electrode placed inside the combustion chamber; the car electronic card adapts the combustion parameters in the event of variations in the density of the air or of the fuel. This allows VICTRIX TT ErP to be powered with any type of fuel (methane/LPG or propane air), by intervening only on the electronic board software even at a later time (for example at the first commissioning by the Authorized Assistance Centre). The boiler is therefore supplied with a single product code. Product Warranty All products for sale on our site are new and packed.

Ferroli condensing boiler Bluehelix HiTech RRT 34 H complete with low NOx methane or LPG fume exhaust kit for heating only - New Heating ERP Class A Heating capacity max / min kW 34.7 / 3.5 Efficiency 30% % 109.5 NOx emission class (EN 15502-1) - 6 Heating expansion vessel capacity 8 litres Protection degree (IEC 60529) IP X4D Dimensions HxWxD mm 700x420x320 Bluehelix HiTech RRT H (Heating Only)   The new user interface with «capsense» technology, without mechanical keys and equipped with a 2.8'' graphic display, allows the user to interact with the product easily and extremely simply. Thanks to the energy efficiency of the space heating ηs 94% among the highest in the category (Class A ErP, scale from G to A++) and to the combination with the Connect remote control, able to read the external temperature directly from the internet, reaches the system energy class A+ (scale from G to A+++). Easily adapts to load conditions thanks to the wide modulation range which can reach up to 1:10 (1:10 mod. 34 C, 1:9 mod. 28 C, 1:7 mod 24 C). Thanks to the "Hydrogen plug-in" system, one of its most important innovations, it is already able to self-regulate to work with mixtures of natural gas and hydrogen, which will soon arrive in Europe, to combat global warming. Designed to fully satisfy the requests for a "robust" product from every point of view thanks to the high-passage primary exchanger capable of guaranteeing maximum efficiency and reliability over time also, and not only, as a replacement for old generators in particularly dirty systems . Silence at the top The particularly careful design of BLUEHELIX HITECH RRT has made it possible to achieve significant values ​​in terms of silence and acoustic comfort, so much so that it could almost be difficult to distinguish the background noise of a home from the noise produced by the boiler during normal operation. It will be difficult to realize whether the boiler is on or off from its noise, as on older generations of boilers, because even the on/off transients have been optimized according to acoustic comfort. The planning also took care of the design, creating a precious mantle in 3 removable pieces, which descends to cover the pipe connections Characteristics Boiler with thick stainless steel primary exchanger , with increased passages (at the top of the category) to guarantee durability and reduced maintenance, it maintains high efficiency even on old systems with oxidation and dirt thanks to the combination with the CONNECT modulating remote control and the reading of the external temperature directly from the internet, it reaches the maximum energy efficiency A+ (scale from G to A+++) Class 6 NOx: already in line with the provisions of the ErP regulation from 26.09.2018 (NOx emissions < 56mg/kWh) MC2: Multi Combustion Control, new combustion system with patented gas-adaptive technology of industrial origin for better adaptability of use to varying conditions of the gas network (e.g. fluctuations or reduced pressures) MGR: Methane LPG Ready, through a simple configuration the boiler is able to operate on both methane and LPG without the use of additional conversion kits Exclusive exchanger-burner system with self-cooled door (without insulators): simplifies maintenance and reduces its cost thanks to fewer perishable parts Hydraulic connections covered by the boiler shell Large backlit multifunction graphic display for easy and correct parameter setting Standard by-pass Easily adapts to load conditions thanks to the wide modulation range which can reach up to 1:10 (1:10 mod. 34 C, 1:9 mod. 28 C, 1:7 mod 24 C). Particularly suitable for operation in flues that require "heavy" ducting thanks to the approval for operation with 50mm diameter flue pipes FPS: Smoke Protection System. The flue clapet valve inserted as standard on the boiler allows easy connection to pressurized collective flue systems (e.g. in renovations), in accordance with the UNI 7129 standard Designed to simplify and facilitate normal maintenance and cleaning operations Digital flame control with three re-ignition attempts in the event of malfunction due to lack of flame detection (only for methane operation) Place of installation: also for outdoors in a partially protected place up to -5°C as standard and up to -15°C with the help of the optional antifreeze heater kit Boiler control The new user interface with ''capsense'' technology, without mechanical keys and equipped with a 2.8'' graphic display, allows the user to interact with the product easily and extremely simply, customizing the operation of the appliance in so as to manage the environmental comfort according to one's needs. Thanks to the remote connection via bus, this can also be done directly from the CONNECT remote control, even via smartphone. The boiler is also set up to connect a second room thermostat to dedicated terminals to manage multi-zone systems. TOP EFFICIENCY Even on old systems (replacements) The BLUEHELIX HITECH RRT heat exchanger THERMOBALANCE™ (fig. A) compared to the more classic and widespread steel exchanger (fig. B) also used in the past by the Ferroli Group exclusively on a small series of boilers produced for the market English, and then immediately abandoned in favor of the evolution towards the proprietary steel exchanger used in the Bluehelix models (2012 -> ). This geometry allows the heat exchanger of the THERMOBALANCE heating unit to operate almost at maximum design efficiency even in conditions of partial blockage, while with the same amount of deposits and sediments (e.g. due to installation on old systems) the exchanger in fig . B tends to block up much faster in the part in contact with the flame due to the reduced passage area of ​​the fluid, in which a real barrier of deposits * is formed which hinder the heat exchange and reduce the efficiency beyond below the nominal values MC2 Multi Combustion Control The electronics control the flame ionization current in order to ensure optimal combustion as the air density or gas quality varies. The relationship between the air/gas ratio (λ) and the flame ionization signal is used to control the air-gas ratio itself and therefore the combustion. MC2 : Multi Combustion Control, the new combustion system with patented gas-adaptive technology improves the adaptability of use as the conditions of the gas network vary (e.g. fluctuations or reduced pressures). EASY MAINTENANCE Trouble-free maintenance At the time of the first maintenance, the technician can appreciate the care with which every detail has been designed to facilitate his work. Thanks to the maximum accessibility of the main components, the "Thermobalance"TM thermal group allows maintenance to be carried out with maximum precision and speed. Some examples: Internal accessibility is favored by the 3-piece mantle with removable side panels. The electrical box of the electronic card can be easily extracted from the chassis leaving free access to the internal parts. - The fan, offset from the burner and placed underneath, must not be disassembled to access the steel burner-exchanger group. The burner door is totally self-air-cooled and therefore does not require an insulating panel, avoiding the risk that this could be damaged or broken during disassembly for cleaning. The burner can be disassembled by loosening just 3 bolts leaving free access to the stainless steel exchanger. The exchanger with extra-large passages is designed to challenge the hardest waters and is easy to clean thanks to the non-collectorised single-pipe circuit. Any disassembly and replacement of the plate heat exchanger takes place simply by removing the two Allen bolts accessible from the front Warranty All products for sale on our site are new and packed. The warranty on this item is 24 months from the date of purchase.
