Built to be installed outdoors in partially protected places and prepared for integration with a solar panel system. It has an excellent quality-price ratio and is entirely Made in Italy with a 2-year guarantee. The cheapest in its category Arrangement for solar systems Eco-comfort system for rapid domestic hot water production High efficiency low consumption circulator (class A) Ideal for residential homes up to 120 m2 2 Year Warranty Divaproject is a heat generator for heating and instant domestic hot water production. The series has been designed in each of its components to have top performance in its category while maintaining characteristics of simplicity and compactness. The control electronics allow for easy and functional combination with solar collector systems. The series includes two models: C24 and C30 The boiler is designed to operate on natural gas and LPG or even on propane air by means of a special transformation. The efficiency of Divaproject is the maximum for its category, certified at 3 stars according to the 92/42 EEC Directive for energy classification Components Expansion vessel Combustion chamber Copper primary exchanger Atmospheric burner Sanitary exchanger Modulating gas valve Motorized 3-way valve Boiler control Control panel and functions Divaproject's control and management electronics allow the user to customize the operation of the appliance in order to manage environmental comfort according to one's needs. The control panel with the adjustment knobs makes the programming operations for the production of hot water, both for domestic hot water and for heating, extremely easy and intuitive Remote control "ROMEO" timer Divaproject boilers can be combined with a wide range of remote timer controls which allow the appliance to be adjusted and operated remotely. The ROMEO series consists of 4 models, respectively with weekly or daily comfort programming and with the possibility of choosing between wired or wireless connection for both With ROMEO you can: Adjust the heating and DHW temperatures Know the operating status of the boiler View the temperatures inside and outside the house Restart the boiler in case of temporary lockout Program the daily or weekly environmental comfort Activate/deactivate the heating function via the telephone The ROMEO modulating function allows boiler output to be modulated as the set room temperature value is reached. This improves the quality of comfort by eliminating heat peaks with consequent energy savings. With solar systems Sun Easy function Divaproject boilers have been designed to be easily inserted in systems made with the most recent technologies. The SUN EASY system, standard on the boiler, makes use of electronics that simplify the combination with both natural and forced circulation solar panels. Through a sensor placed on the DHW circuit, it continuously controls the temperature of the water coming from the solar panels, foreseeing the ignition of the burner only if the latter drops below the level necessary to guarantee optimal comfort for the user Comfort and Safety Functions Eco-Comfort function In COMFORT mode, thanks to the particular heat exchanger temperature maintenance system, the delivery of domestic hot water becomes even faster and more comfortable. In ECO mode, the production of domestic hot water takes place according to traditional standards. Antifreeze function Even in stand-by mode, i.e. in the absence of a heat request, if a water temperature of 5°C is detected, it activates the anti-freeze protection by igniting the burner at minimum power, in order to avoid damage due to freezing. Post-circulation device All models are equipped with this particular timed device which allows, after the burner has been switched off in heating mode, to recover all the heat accumulated due to thermal inertia in the exchanger, transferring it to the radiators and therefore to the rooms to be heated Circulation anti-blocking device After 24 hours of inactivity, the boiler circulator is automatically started for about 5 seconds to prevent it from blocking after a long period of inactivity.

Designed to meet all the needs of its customers, the Immergas meior Nike boiler respects the environment (ErP), as well as guaranteeing the functions that preserve the integrity of the generator over time, it also has the function of managing the systems with solar system, capable of delaying ignition to optimize the reading of the incoming water coming from the solar tank. This function is even more performing with the aid of the DHW inlet probe kit. Finally, to facilitate installation, it is made up of unchanged attachments to ensure that it is replaced with other instantaneous wall-hung models in the Immergas range. Dimensions (HxWxD): 785x440x340; Product Guarantee The warranty on this item is 24 months from the date of purchase.

It can be integrated into solar systems and, thanks to the easy front access system, allows extreme maintainability without the need for tools. It is available in the heating and domestic hot water production version: 24 kW (open chamber). Characteristics: Digital multifunction display Continuous modulation high efficiency circulator Predisposition for on-off thermoregulation Predisposition solar systems natural circulation Self-diagnosis system by code Mono-temperature zone management Primary heat exchanger in copper Double exchanger technology Integral minimum pressure switch Cold water inlet filters and heating return High efficiency circulator with continuous modulation: It allows automatic adaptation of the power based on the system temperature, guaranteeing boiler performance and reducing electricity consumption. Optimizing thermal efficiency.ÿ Optimization of comfort with constant temperature.ÿ Maximum silence. Ecodesign Directive: In fact, after very long negotiations, the ÿEcodesign regulationÿ was approved, which introduces a new energy labeling on minimum efficiency standards for boilers.ÿIn particular, an energy classification from A+ to G is envisaged for space heating appliances and from A to G for appliances for the production of domestic hot water. ÿHence the obligation to installÿonly condensing boilers, heat generators capable of recovering a large part of the latent heat contained in the fumes which, otherwise, would be dispersed in the chimneyÿas occurs in traditional boilers. The recovered heat is transferred to the heating system, making it possible to achieve a yield of 106% with 92% of the traditional boiler and 84/85% of an oldÿÿtraditional generator.ÿThe installation obligation concerns manufacturers of boilers which will no longer be able to place on the market non-condensing starting from 26 September 2015. This means that starting from this date, anyone who wants to install a boiler in their own home will have to install only condensing models. Only one particular type of non-condensing boiler will continue to be produced which is technically called open room? to be installedÿ when it is not possible to replace an old boiler with a condensing boilerÿdue to problems related to the collective flueÿof some multi-family buildings. Products for heating water and the environment represent around 30% of the world's energy consumption in Europe.ÿ Designing eco-friendly products and promoting high performance technologies to end users in 2020 will lead to: An annual energy saving equivalent to 56 million tons of oil, quantifiable to the savings obtained if the water and environmental heating systems of two large nations like Italy were deactivated. As of 26 September 2015, the ErP regulation and ÿenergy labelingÿwill be applied in Europe to water and space heating products (boilers, heat pumps, micro-CHP devices, water heaters, and hot water storage tanks) u. There are different labels, based on the type and function of the product (only room water heating of both, and in this case the label must bear both classifications). In addition to the energy class, the label provides other information that could be useful for understanding which product has the least environmental impact (for example power and consumption in different climatic zones, noise levels, etc.). It is possible to increase the energy efficiency of hot water production and space heating by connecting several products and accessories in one system. In this case it is necessary to prepare a system label in addition to that relating to the single product Warranty All products for sale on our site are new and packed. The guarantee on this article is 24 months from the date of purchase.
