All this by 2020. To achieve these objectives, the EU has issued the ErP Directive (energy related products) which specifies the minimum eco-design requirements for equipment that uses energy, including energy efficiency. The world of heating will also be affected by this revolutionary change. In fact, from 2015 the energy efficiency of boilers will be based on new performance indexes that will take into account seasonal performance. Among the most significant changes to the new methodology for measuring seasonal efficiency are the introduction of different nominal temperatures, operation also at partial loads and in standby mode. The new methodology will make it possible to evaluate the performance of a boiler in real conditions, based on the level of efficiency calculated over an entire year. ecoTEC PLUS VMW+ The most efficient and versatile combi condensing boiler there is. ecoTEC plus. Wall-mounted condensing boilers capable of always guaranteeing maximum efficiency and maximum comfort. This is German quality. ecoTEC plus has always been the most popular Vaillant boiler. Today it guarantees even lower consumption, a further increase in efficiency and versatility and the certainty of immediate sanitary comfort without jolts. The best of Vaillant technology to satisfy every need Every component and every function of ecoTEC plus has been designed to combine efficiency and reduced consumption in favor of greater respect for the environment. ecoTEC plus self-adapts to your needs by always choosing the most economical solution, mixing the right amount of gas and air; all this with an electrical consumption of less than 2 Watts (less than half of a radio in operation). The combined version satisfies all comfort needs, guaranteeing both constant hot water without sudden changes in temperature and a comfortable climate. Sanitary comfort, in particular, is managed by the efficient Aqua Comfort pre-heating system which, thanks to 4 probes, controls, verifies and guarantees the immediate delivery of hot water always at the same temperature. Lots of hot water, immediately, without sudden changes is the real comfort offered by ecoTEC plus. From today it can also be installed outdoors where the climate is mild even in winter. In fact, the boiler has a standard antifreeze device which allows it to resist down to -5°C. To have heating and domestic hot water in a single solution The VMW ecoTEC plus condensing wall-mounted boilers combine the production of domestic hot water with the heating function. Unlike all the other boilers, the Vaillant ELGA system is installed inside, which expands the modulation range, but above all electronically regulates and monitors combustion to always ensure the lowest gas consumption, guaranteeing maximum efficiency. The boiler adjusts itself automatically and continuously, as if it were assisted every 30 seconds. In addition to a new, simpler and more intuitive design, the new electronics together with a very high efficiency pump make ecoTEC plus VMW+ the wall-mounted condensing boiler that consumes less on the European market. the ecoTEC plus VMW+ boiler is compatible with all Vaillant components and accessories already on the market. The dimensions are reduced 70cm high, 44cm wide and 35cm deep (identical to the previous version), the weight has been optimized making installation easier. and with vSMART... and go to Class A+ (Optional) All models of the ecoTEC plus VMW+ range have an efficiency etas = 94%. For this reason, if combined with a class VI thermoregulation (such as vSMART), they reach a system efficiency of 98% and therefore the ErP energy class in heating A+.

FLEXIBLE INSTALLATION The characteristics of Residence and its compact dimensions make it the ideal solution for both indoor and recessed installation (model 25 KIS only) or outdoors in a partially protected place. RESIDENCE, HEART OF STEEL The new RESIDENCE exchanger is made of stainless steel, with a smooth tube with a large section to guarantee the best efficiency and cleanliness over time. NEW PRIMARY EXCHANGER IN STAINLESS STEEL The single coil geometry (hydraulic circuit in series) guarantees constant flow in all sections of the exchanger and intrinsically prevents clogging. Front access facilitates periodic maintenance and cleaning of the combustion chamber. SELF-ADAPTING ELECTRONIC COMBUSTION CONTROL The new Residence is equipped with the intelligent ACC combustion control system, which guarantees that the process always takes place in an optimal manner in any condition, thanks to the modulating gas valve and the ionisation electrode. Thanks to the ACC, Residence is able to automatically adapt to the fuel (methane or LPG) without resorting to specific codes or accessory conversion kits. Residence also reacts to the variation of the fuel title and to the pressure drops on the flue gas side. The ACC system detects the excess air value and intervenes by modulating the mixture. The ACC system also simplifies installation. During ignition, it does not require calibration and it is sufficient to select the type of combustible gas used by the boiler via the interface, if different from the default one (methane). Since the system keeps the value of the CO2 produced constant, even the smoke control during the ignition phase is no longer necessary for the correct functioning of the product. Controlling combustion also means guaranteeing constant emissions, which are always well below the limits set by the law. In fact, if the process takes place in an optimal manner, the gases produced will also have the best theoretical composition with respect to the other conditions. MANY NEEDS, ONE SOLUTION RESIDENCE IS ALWAYS THE IDEAL CHOICE THANKS TO THE TECHNICAL SOLUTIONS AND THE COMPACT DIMENSIONS, IT CAN BE USED IN ANY INSTALLATION SITUATION INTERIOR Inside the home, thanks to an elegant aesthetic that allows it to be inserted pleasantly into any environment. OUTDOOR Outdoors in a partially protected place, thanks to the IPX5D degree of protection and the accessory antifreeze heater kit RECESSED Inside a built-in box thanks to its compact dimensions (model 25 KIS only).

Unical KON X SLIM 35 C condensing boiler complete with low NOx LPG fume exhaust kit - New Minimum/nominal useful power in condensing kW 4.6 ÷ 33.8 Heating efficiency class A Declared load profile XL Sanitary efficiency class A Efficiency at nominal thermal power in high temperature regime (Tr 60°C / Tm 80°C) η4 % 88.7 Production DHW cont. Dt 25 K (mixed) l/min 18.6 Total expansion vessel capacity l 6 IP X5D degree of protection NOx class 5 Dimensions HxWxD mm 800x520x180 KON X SLIM KONx SLIM is a condensing boiler running on methane or LPG, with instantaneous production of domestic hot water. Covered with a satin finish AISI 304 stainless steel casing, it is ideal for outdoor installations, but equally elegant indoors. KONx SLIM is: Performant 24 and 35 kW (Range rated) Modulation ratio 1:8 Low NOx class 5 High energy efficiency A+ (System) the top of the category, >98% Hs (superior calorific value) Insulated and protected IP X5D, suitable for outdoor installation according to current standards (up to -15°C with antifreeze kit) Extremely compact with its depth of only 18 cm, Unical's record among wall-hung condensing boilers KONx SLIM, thanks to the RCh chronothermostat, OT multiprogram modulator, connected to the ambient and external probes supplied as standard, reaches seasonal efficiency equal to energy class A+ in heating. HWS "Hot Water Speed" is the new KONx SLIM electronics that switches from heating to DHW function with burner and pump always active, considerably improving user comfort who does not have to wait for hot water. Covered with a satin-finish AISI 304 stainless steel casing with a tapered-edge casing finish, KONx SLIM appears to have an essential and very elegant line, combining, with its hi-tech style, with the other appliances in the house Super small size depth of only 18cm Management of 2 temperature zones (high/low) by applying a second on/off thermostat Sliding temperature programmed to operate with the lowest possible delivery temperature to help save energy Intelligent system filling to guarantee functionality If the pressure is below 0.4 bar in the system circuit, the automatic water filling starts for 30 seconds once a day. If the request is repeated several times, a warning signal appears on the remote control Anti-overheating post-circulation automatically after the burner goes out, the boiler keeps the pump running for 5 minutes, preserving the components Chimney sweep function allows maintenance technicians to carry out the checks required by current standards in terms of efficiency and emissions Multigas operation (natural gas or LPG) with simplified switching Double expansion tank If necessary, it can mount an external auxiliary expansion tank (optional) Product Warranty All products for sale on our site are new and packed.
