CONDENSING EOLO Extra kW HP Wall-hung condensing boiler for high temperature systems ADVANTAGES EOLO Extra kW HP Wall-hung condensing boiler designed for high temperature systems The continuous investment of Immergas in projecting and manufacturing domestic use gas boilers, the constant research for low environmental impact solutions and the always new requests from the market’s side, gave birth to EOLO Extra kW HP boilers. HP range boilers distinguish for the ability to achieve high efficiency and respond to the installation requirements of new construction buildings. In particular, they satisfy the specific exigencies of high temperature heating systems, still being able to benefit from condensing boilers combustion efficiency. HIGH EFFICIENCY AND LOW CONSUMPTIONS The technology characterizing EOLO Extra kW HP boilers allows to accomplish the best comfort optimizing the efficiency and reducing gas consumption to the minimum. Thanks to a special combustion system, compared to traditional appliances, HP range boilers greatly exploit the combustion generated heat with great advantages in terms of performances. The nominal outputs of 24 and 30 kW fully suit the home wellness and sanitary comfort necessities of the most demanding users. EASY INSTALLATION The compact dimensions of EOLO Extra kW HP boilers consent to easily install them in your home, even inside the kitchen cupboards, or to locate them outdoor in a protected place, for example under a balcony. The boiler installation features a simple connection to the condensate drain (e.g. to the kitchen sink siphon), while the use of the proper plastic flue system allows for an easy evacuation of the combustion products in any installation situation (roof, wall or relined chimneys). REMOTE THERMOREGULATION: A COMFORT CHOICE The appliance can be remotely controlled using the CAR remote control (as option), allowing a better climatic regulation of the room temperatures. In fact, it substitutes the boiler control board carrying out all its functions. This last aspect results particularly useful when the boiler is installed outdoor, allowing to manage the appliance staying comfortably inside your home. HP boilers can be also combined with other Immergas thermoregulation range devices. ADVANTAGES .01 .02 .01 MORE ENERGY WITH THE HEAT RECUPERATOR Peculiar characteristic of EOLO Extra kW HP boilers is the use of a special heat recuperator positioned at the bottom of the combustion chamber; this solution allows to transfer further energy to the system, otherwise dispersed by the combustion products. The combustion products heat is given to the system through a copper primary exchanger. The return circuit gets preheated by the outlet flues, inside the heat recuperator. The condensate deriving from it is evacuated by the proper boiler siphon, without interesting the primary exchanger. All EOLO Extra kW HP boilers must be installed in high temperature systems with heating bodies such as radiators or air convectors. .02 GUARANTEED SANITARY COMFORT The sanitary hot water production makes use of an accurately dimensioned heat exchanger to optimize performances over time. EOLO Extra kW HP boilers are equipped with a 16 plate heat exchanger for the 24 kW model and with a 22 plate one for the 30 kW model. OUTDOOR APPROVED The IPX5D electric protection, along with the possibility to install a -15 °C anti freeze protection kit, make HP range boilers suitable for outdoor installation in a partially protected place.
