POWER EFFICIENT HEATED BUILDING Russian patent published in 2013 - IPC E04H1/00 F24D5/10 E04B1/76 

FIELD: construction.

SUBSTANCE: design of a power efficient heated building comprises heat-resistant barrier structures, a heat-resistant foundation, a water tube boiler with a furnace gas feed heater, a system of heat recuperation between flues and plenum air, and also a system of heat recuperation comprising an attic room, a system of air ducts placed inside heat-resistant barrier structures and a heat-resistant foundation. With the purpose of efficient use of not only heat of ventilation air, but also furnace gases in the heating season for regions with cold climate, a gas mixer is installed in the attic room for mixing of the main gas - ventilation air, convectively arriving from building rooms into the attic room and auxiliary gas - furnaces gases convectively arriving along a ventilation channel equipped with a bypass ventilating exhaust from the water tube boiler feed heater.

EFFECT: reduction of fuel burnt for heating of a building and environmentally hazardous gas and air exhausts, higher level of comfort of building rooms, higher durability of bearing parts of barrier building structures, maintenance of necessary technical and sanitary level of moisture in barrier structures and in a heat inertial space under a building.
