<p>#CMT# #/CMT# The installation (100) has an air extraction system for extracting air from a room, where the air extraction system is provided with a motor-driven fan unit (16) to create an extraction air flow in the air extraction system. A water-heater (18) is filled with water to be heated by a part of the extraction air flow. The air extraction system modifies the flow of extraction air for heating water based on an operating state of the water-heater. The air extraction system reduces the part of extraction air flow for heating of water in an observation state with respect to the operating state. #CMT# : #/CMT# An independent claim is also included for a method for regulating a combined room ventilation and water-heater installation. #CMT#USE : #/CMT# Combined ventilation and water-heater installation for a room e.g. garage, laundry room and kitchen, of a dwelling. #CMT#ADVANTAGE : #/CMT# The air extraction system modifies the flow of extraction air for heating water based on the operating state of the water-heater, so as to reduce the flow rate of extracted air supplied to the water-heater based on the operating state of the water-heater, thus reducing the pressure loss of extraction air flow between inlets and outlets of the extraction system, and hence reducing power supplied by the device for creating air flow to reduce energy consumption of the installation while improving heating performance of water and room ventilation performance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a combined ventilation and water-heater installation. 14a : Bypass pipe 16 : Motor-driven fan unit 18 : Water-heater 32 : Outlet 34 : Electronic control unit 100 : Combined ventilation and water-heater installation.</p> |
