Traditional wall-mounted boiler with low NOx emissions, combined for heating and water domestic hot water, ErP efficiency class C in heating, B in domestic hot water with XL profile. Micra 5 E Low NOx , a boiler at the top of its category in terms of consumption and polluting emissions, can feature the exclusive Aquaspeed system for the production of domestic hot water. The exclusive Aquaspeed system guarantees the immediate delivery of domestic hot water at the desired temperature: the preheating of the primary circuit and therefore also of the secondary stainless steel plate exchanger, allows an immediate response from the boiler to any sudden request from the user. Reliability and Hermann Saunier Duval standard quality Specification for branched collective rods (CCr) Low NOx emissions Aquaspeed system for high sanitary comfort Hot water immediately available with pre-heating The exclusive Aquaspeed® system guarantees the immediate delivery of domestic hot water at the desired temperature. The operation of the Aquaspeed® system is brilliant in its simplicity: the DHW exchanger is kept constantly at the set temperature; the hot water, passing through the preheated plates of the exchanger, reaches the taps already at temperature. The pre-heating, combined with the special oversized and externally insulated plate exchanger, allows an abundant quantity of domestic hot water even with low boiler temperatures.
