When buying a heat pump in NZ, a lot of Kiwis make a very common mistake. They choose the wrong size. It is either too small for their requirements, or it’s far too big. Very rarely do they get it just right the first time around. If you’re looking to invest in a new heat pump for winter, we don’t want you to make that same mistake. That is why we urge you to ask us to come around for a free home assessment. We can check out your house and give you our opinion on the right size heat pump for your requirements.
Without our input, you may opt for a heat pump that is far too big for the room you want to heat up. In this case, the preferred temperature will be reached extremely quickly and the unit will cycle on and off, again and again, and again. This repeated on-off process is extremely inefficient (which will be reflected in your power bills) and can significantly reduce the life expectancy of the unit.
On the other side of the coin, if the heat pump is too small, it will run continuously without ever reaching the set point. This will increase defrost requirements by reducing the outdoor coil running temperature and driving it into below zero temperatures for prolonged periods. As the unit will continue to defrost at minimum intervals, it may never catch up and achieve that preferred set point.

- The quality of your current insulation

- The amount of solar gain in your home
