Bad installation & insulation override good equipments
Nibe AMS10-12 (outdoor) + HK200S (indoor with 180-L tank) + SMO20 (control with internet Uplink) supplies hot water & underfloor heating in 2021 2-storey new house, which has good heat insulation (triple grazing, loft installation , exterior wall insulation) plus heat recovery ventilation (minimising heat loss from stale warm air). With correct installation and measures to cut down heat loss through windows, walls, roof, air ventilation, air source heat exchange pump delivers the benefits. With poor installation (lack of experience in the traditional gas, oil central heating contractor sector) & poor heat insulation (in traditional pre-war, post-war houses), none of the modern heat exchange pumps, air recuperation systems could meet expectations.
