The display allows you to view all the information and set the operating parameters in an intuitive and immediate way. Efficiency and savings Wide modulation range: greater efficiency given by fewer starts and stops: with a high modulation ratio, the reduction of the continuous on/off cycles leads to a significant reduction in consumption (by 8-10%) and an equal reduction in polluting emissions adaptation of the thermal power produced to the power dissipated thus avoiding excessive overheating / cooling of the premises GAC Gas Adaptive Control It is an innovative system which, thanks to a new control electronics and a new electronic gas valve, guarantees automatic control of combustion to constantly maintain maximum efficiency values. Advantages: there are no manual interventions – reduced measurements, calibrations with this system, the boiler self-adapts to the quality of the gas (methane) and to the length of the flue gas pipes, keeping the efficiency constant the boiler also constantly self-regulates to maintain the maximum efficiency values ​​favoring a reduction of gas consumption and generating less pollution thanks to the continuous control of emissions. Fully modulating pump with de-aeration The circulation pump can operate at maximum speed, minimum speed or in "automatic" mode: in the latter case, the speed (min./max) will be selected so that the delivery/return ∆T in heating remains constant at 20 °C thus ensuring a significant reduction in pump consumption and, given the lower mechanical stresses (compared to a pump that always runs at maximum speed), also in maintenance costs. During the first ignition phase, we recommend activating the automatic de-aeration function. This function eliminates the presence of air in the heating circuit and therefore avoids any blockages of the boiler, overheating of the system, etc. Guidelines in case of replacement of a conventional boiler with a new condensing one There are two main problems that can be encountered: Flues and smoke exhaust duct Condensate drain To overcome the above, Baxi recommends: the use of a Ø50 mm exhaust pipe Baxi has in fact developed a system that allows easy ducting in existing flues (for 24kW models). For condensing boilers, the novelty is brought about by the low temperatures of the fumes which allow the use of specific plastic materials; however, in the presence of existing 316 stainless steel flues, installed correctly and with gaskets suitable for receiving damp fumes, there are no problems and they can easily be reconnected to the new boilers while it is absolutely not compliant with the use of aluminum flues or smoke pipes . In fact, aluminum is a metal that is not resistant to the acid condensates present in the fumes. (*) Each Ø50 mm diameter bend decreases the length of the drain by 4m the use of the condensate drain pump Baxi has designed this kit to collect the condensate produced by condensing boilers for domestic use: the pump allows the creation of condensate drainage systems in the absence of natural drainage near the boiler. The operation of condensing boilers determines the formation of condensate, due to the principle of condensation. This water therefore needs to be disposed of through special drains. If there is no adequate slope and therefore it is not possible to dispose of the condensate by gravity, it is necessary to install a pump that conveys it towards the drains. The pumps used are also equipped with special non-return valves to avoid bacterial contamination due to any stagnation and return of the waste water. The use of buildings avoiding the use of annoying pipes. Condensing Boilers The ranges of Duo-tec+ condensing boilers are characterized by very high modulation, the GAC system and remote capability. Very high modulation The wide modulation range up to 1:10 allows a reduction of the switching on/off of the boiler, resulting in an improvement in efficiency and consequently a considerable saving. GAC system The GAC (Gas Adaptive Control) system continuously measures the flame signal during boiler operation and adjusts the gas flow rate in order to keep the combustion quality constant. The resulting advantages are: reduction of installation times/ there are no manual adjustments to make/ reduction of gas consumption and lower environmental impact. Remote control For optimal comfort management, the Duo-tec+ offer a wide range of modulating units. In Platinum+ the extractable control panel and room thermostat are supplied STANDARD with the boiler. Available as optionals are the modulating chronothermostat and the LED interfaces that allow the units to be remotely remoted via wire or wireless. Also for the Duo-tec models, the offer of thermoregulation accessories includes both the remote control and climatic regulator and the wired or wireless modulating chronothermostat, in addition to the wired or wireless modulating thermostat. All boilers are provided with an antifreeze function and IPX5D degree of protection. Duo-tec Compact+ wide modulation range up to 1:7 greater efficiency and silence GAC (gas adaptive control): automatic combustion control high-efficiency circulation pump with total modulation digital control panel with large backlit LCD display predisposition for combination with the Baxi integrated solar system Ø50 mm exhaust pipe: solution for restoring flues - mod 24 kW ultra-compact dimensions: 700x400x299 mm antifreeze function and IPX5D degree of protection Product Guarantee: All products for sale on our site are new and packed.

The performances Energy classification DHW load profile (maximum flow rate at the corresponding efficiency declared in DHW) Efficiency in the production of domestic hot water FOR COMBINED BOILERS The "climate-energy 20/20/20" package sets ambitious targets for the reduction of greenhouse gas emissions, of energy consumption as well as the increase in the use of renewable energies, corresponding to a percentage of 20% to be reached by 2020. In this context, the European regulation ErP (Energy Related Products) introduces an energy classification also for water generators hot water for space heating and domestic hot water purposes. This classification translates into an energy label which must necessarily accompany all the products affected by the Regulation, introduced on the market from 26 September 2015. The labeling constitutes an easy guide for the consumer, who can choose - through standardized and objective indications - the product more efficient. In this way, the choice will be the most sparing in terms of consumption for the benefit of the user, but also the most virtuous for energy balances and consequently, for the environment. The most significant parameters indicated on the label are the seasonal efficiency index in heating and efficiency in the eventual production of domestic hot water, according to a scale which, in the case of the single boiler product, ranges from A to G*. Furthermore, for combined boilers, a load profile is indicated corresponding to the DHW flow rate of the appliance measured in a series of typical samplings, guaranteeing at least the declared DHW efficiency. This index is identified with a letter/”size” (S, M …XXL). Solar circuit integration DIVACONDENS D PLUS boasts electronics that simplify integration with thermal solar systems, both with natural and forced circulation. The microprocessor controls the temperature of the water coming from the solar circuit through the domestic hot water sensor and turns on the burner only if necessary. To reach the desired temperature, SUN EASY allows considerable savings even during the coldest seasons, exploiting and integrating even the smallest solar contribution, otherwise lost. In case of insufficient irradiation and therefore a modest pre-heating of the domestic water, the boiler will contribute with the heat necessary to reach the required set point temperature. If the sun and the solar system fulfill their "duty" no integration by the boiler will be necessary, the hot water will be conveyed to the tap, without the need for additional devices, with the mixing of the thermostatic valves. Safety and comfort ANTIFREEZE In the event that the temperature in the boiler drops to 5°C, the burner ignites automatically and the circulator is activated in order to protect the appliance from damage caused by frost. This function is active with the boiler powered by the gas circuit and under electrical voltage. POST-CIRCULATION This function makes it possible to recover all the heat supplied by thermal inertia of the exchanger and transfer it to the heating system, and consequently to the rooms to be heated. This is a timer function (customizable duration) and is active after the burner goes out in heating mode. SLIDING TEMPERATURE OPERATION With the installation of the “external probe” kit it is possible to operate the boiler in sliding temperature. This means that without using the system temperature adjustment keys, the boiler will self-regulate according to the variations in external temperatures. All this translates into energy savings while ensuring maximum comfort for the user. EASY CONTROL The electronic board of DIVACONDENS D PLUS adopts the Opentherm protocol. It allows the integration of other peripheral control units such as, for example, the ROMEO remote timer control. In fact, the Opentherm standard has been specially designed to share the logic and operating algorithms of the boiler with other additional control units. As a digital protocol, it allows total integration between the boiler and the satellite, with full control of the functions from the boiler and similarly from its satellite.
