Choosing the right size heat pump is important to maintain comfortable indoor conditions during colder months. Factors such as location, room size, and insulation levels within a room are all factors which determine which heat pump size needs to be installed.
Insulation and building design are two important factors influencing the degree of heat loss inside a home. A poorly insulated old house will lose heat at a faster rate; therefore, a larger heat pump system will be needed to compensate for this heat loss.
Outdoor ambient conditions in winter also play a big role in unit size selection. When temperatures drop, the output capacity of the heat pump also drops. Areas of New Zealand that experience sub-zero temperatures in winter will require either a larger capacity heat pump or an upgrade to a Mitsubishi Electric HyperCore® Heat Pump, in comparison to a same sized room in a warmer region. It is therefore very important that units are not undersized in low ambient conditions.
