Cold climate zone
Heat pump installers in Christchurch
Canterbury sees real winter — frost, occasional snow, sub-zero overnights. The published kW rating on heat pumps is measured at 7°C; at Christchurch's actual cold-snap temperatures it can fall 20–30%. Sizing matters.
Local climate notes
DWG-03 / CHRISTCHURCH
Cold winters (lows -1 to 4°C, occasional frost). Add ~20% to standard kW-per-m² for living areas, and check the unit's rated heating capacity at 2°C, not 7°C.
