The one present on KON stands out from others for its low pressure drops, thus optimising the circulation of hot water in the boiler.\u003cbr\u003eTotal premix burner with constant combustion ratio with modulating electropneumatic gas valve and modulating fan\u003cbr\u003eElectronic ignition and single-electrode flame control\u003cbr\u003eModulation ratio 1:8\u003cbr\u003eMinimum heating power adjustment\u003cbr\u003eThree-way diverter valve\u003cbr\u003eSafety limit thermostat\u003cbr\u003eOperation down to -15°\u003cbr\u003eFlow temperature sensor\u003cbr\u003eReturn temperature sensor\u003cbr\u003eDomestic hot water temperature sensor (KON \"C\" model only)\u003cbr\u003eExpansion tank 8 litres\u003cbr\u003eAutomatic air vent\u003cbr\u003eSafety pressure switch against lack of water\u003cbr\u003e3 bar safety valve\u003cbr\u003eControl panel with display, function selector and temperature adjustment potentiometer and unlock button\u003cbr\u003eHydrometer\u003cbr\u003eBurner inspection and exchanger cleaning system with quick-release closures\u003cbr\u003ePaper mounting template for hydraulic connection pre-arrangement\u003cbr\u003eFixing plugs\u003cbr\u003eCondensate drain trap\u003cbr\u003eFixed flow circulator with air vent: Robust, powerful and reliable with excellent flow rate and head characteristics.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003ePatented exchanger: It is made of a special Aluminium\/Silicon\/Magnesium alloy that ensures its efficiency and resistance, so much so that it is guaranteed by Unical for 5 years. Thanks to the internal heat exchange configuration, efficiencies of over 107% are achieved in condensing mode, which means great economic savings and a very low environmental impact for the user.\u003cbr\u003e\u003cbr\u003eHWS \"Hot Water Speed\": to eliminate the delay in DHW production: The transition from heating function to DHW production normally occurs with a delay of about 6 or more seconds, depending on the switching of the priority valve that turns off the pump and burner. In fact, the user has to wait uncomfortably in the shower for the system to restart. The new electronics adopted here, instead, perform a \"change on the fly\" with the burner and pump always operating, significantly improving user comfort.\u003cbr\u003e\u003cbr\u003e2-zone management with 2 thermostats: KON also offers installation flexibility. Ideal for all systems, thanks to the electronics that allow managing 2 heating zones at different temperatures (high for radiators and fan-coils, low for radiant panel systems) by controlling them with both modulating and on-off dedicated thermostats.\u003cbr\u003e\u003cbr\u003eElectronic anti-freeze function: activates at 5°C and is active for both domestic hot water and heating, bringing the boiler temperature to 15°C. This prevents the risk of KON freezing if low temperatures persist in the room where it is installed. If there is a lack of gas, a fault signal will appear on the display.\u003cbr\u003e\u003cbr\u003ePump anti-blocking function: even after long periods of inactivity, KON's electronics send a 5-second command pulse every 24 hours of downtime, starting the pump rotor and thus preventing oxidation from blocking it.\u003cbr\u003e\u003cbr\u003ePump post-circulation function: for 15 seconds, it controls the thermal balance between flow and return in all conditions, even after intense DHW withdrawals, while in heating, with a duration of 5 minutes, it allows all residual thermal inertia to be dissipated.\u003cbr\u003e\u003cbr\u003eChimney sweep function: facilitates combustion adjustment operations. By pressing the unlock button for more than 5 seconds, it will be possible to operate at minimum or maximum power for 15 minutes to analyse combustion.\u003cbr\u003e\u003cbr\u003eSliding temperature operation for maximum operating economy.","brand":"Unical","offers":[{"title":"GPL \/ COAXIAL","offer_id":55708330459461,"sku":"UNICAL-KONM35-GPL-COASSIALE","price":1410.0,"currency_code":"EUR","in_stock":true},{"title":"GPL \/ SPLIT","offer_id":55708330492229,"sku":"UNICAL-KONM35-GPL-SDOPPIATO","price":1410.0,"currency_code":"EUR","in_stock":true},{"title":"METHANE \/ COAXIAL","offer_id":55708330524997,"sku":"UNICAL-KONM35-METANO-COASSIALE","price":1410.0,"currency_code":"EUR","in_stock":true},{"title":"METHANE \/ SPLIT","offer_id":55708330557765,"sku":"UNICAL-KONM35-METANO-SDOPPIATO","price":1410.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0952\/2023\/6613\/files\/konm_1_1.jpg?v=1758534784","url":"https:\/\/www.worldclima.com\/en\/products\/caldaia-a-condensazione-unical-kon-m-c35-kw-con-kit-fumi","provider":"Worldclima","version":"1.0","type":"link"}
