Choosing the right sized heat pump is key to ensuring optimum comfort levels; particularly when outdoor temperatures drop. From location to room size, every home is as individual as its owner, with many factors determining which heat pump size should be installed.
As such, Mitsubishi Electric recommends that a free in-home consultation and quote is always completed by an authorised Mitsubishi Electric dealer before a system is purchased.
Insulation and building orientation are key factors which may influence the degree of heat loss in a home. An older style home with poor insulation will lose indoor heat much quicker than a modern well insulated home that faces north. The quicker a home loses its heat, the bigger the heat pump system will need to be to overcome 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 (like most of the South Island) will require either a larger capacity heat pump or an upgrade to a HyperCore® Heat Pump, in comparison to a same sized room in the Auckland region. It is therefore extremely important that units are not undersized in low ambient conditions.
