What size heat pump will I need for my home?
Modern inverter Heat Pumps have a greater capacity for variations in temperature. That is because they can increase pr decrease their output, but obviously, there is a limit. It takes almost twice as much energy to heat a house from 2˚ – 20˚C as from 7˚ – 20˚C. Therefore; if you want to make sure you are going to get heating in all situations the Heat Pump needs to be sized correctly.
-Why is this so important? If the Heat Pump is incorrectly sized it will not work correctly to heat or cool your room and will cost you a lot more money than it should to run the appliance. Hence why it is so important to be sure your installer head selected a correctly sized unit.
How important is good installation?
Installation is critical. Sizing, positioning and installation are very important to good operation. The units require connecting piping plus professional wiring during installation. The piping can carry huge pressures and without all attributes of a skilled installer, there will be major problems later. Correct installation requires specialist tools with a combined worth of $5000. Fujitsu Accredited installers are your safeguard of sound, professional workmanship, and although they are not employees or agents, they have the tools and have contracted to follow the installation instructions.
Will a Heat Pump heat my entire house?
Heat Pumps are like powerful, yet efficient fan heaters. A typical Heat Pump provides the same amount of heat as having three fan heaters lined up together, but only costs around the same as running a single fan heater. So if you can heat your house today from one heating position then you can probably do so with a heat pump. However typically, Heat Pumps are sized and installed to heat a single room or open area. To heat your entire house you would most likely need several Heat Pumps or a ducted or multi system.
How 'environmentally safe' are Heat Pumps?
EECA (Energy Efficiency and Conservation Authority) recommend heat pumps for heating, because they use significantly less energy to heat your home than any other type of cheating. This reduces both pollution and the release of green house gasses. Check the model you are buying for its Energy Star rating.
How are Heat Pumps cheaper than heaters?
A heat pump simply “transfers” heat from the atmosphere outside, to inside your home. All other heaters use an element (electricity) or naked flame (gas, open fires) to “convert” energy to heat heat. The only energy a Heat Pump needs is the electricity to drive the fans and compressor. The result is up to 4 times less energy needed, saving your heating bill, and the environment too.
Do Heat Pumps need maintenance?
Like all things mechanical a Heat Pump which receives regular maintenance will perform better than a neglected one. That performance reduction is reflected in the cost to run and the output. the filter associated with the indoor unit should be cleaned to ensure a good airflow. We recommend cleaning the filters yourself at least twice per year. In addition the outdoor unit should be kept clear from greenery and the coil clean from blockage.

How much will it cost to buy and install a Heat Pump?
The cost of a Heat Pump is different for each home and will depend on the size and type of Heat Pump, and how easy it is to install. A hi-wall Inverter single system, suitable for a small area or bedroom, starts at around $2,500 for a 3kW unit including installation. Larger capacity models – say between 5kW and 9kW cost between $3,200 and $4,800 including GST and installation. Some local governments are offering financial assistance if you are replacing an open fire or a solid fuel burner. Your Fujitsu Accredited Installer will advise if this is possible in your area.
How much does it cost to run a Heat Pump?
In response to our most commonly asked question, we have prepared our own Fujitsu Heat Pump comparison chart to compare Heat Pumps commonly installed by us. We have estimated the weekly and monthly cost of running a Heat Pump, and the Heat Pump efficiency. All of those Fujitsu Heat Pumps have been installed professionally throughout New Zealand by us at Heat Pump City.
Heat Pump running costs are based on running the unit 7hrs/day, auto fan and on 20-22˚C. These are geographic variables of course.
Can Heat Pumps help with condensation?
Yes they can. Condensation is caused by warm moist air cooling and condensing. There are two ways to stop “crying windows”. You can either remove the warm moist air (ventilation) or, you can stop it from cooling by heating it. The best option is to do both, but the problem is that in winter the fresh air (ventilation) can be very cold, and expensive to heat. Better to keep area warm.
Will a Heat Pump dehumidify?
Yes. They will dehumidify in cooling mode, in summer. They will not “decondensate” in heating mode (in winter). In winter, your Heat Pump will keep your room, or house, above the dew point so condensation does not form. However, in summer uncomfortable humidity occurs, at which point you change your Heat Pump to cooling.
Where do I place the inside unit?
Positioning is important. Heat Pumps are like big fan heaters and your installer should consider the airflow that will be created, along with the need to circulate the warm air. Consider the area that is to be heated so that air can circulate freely and not be short-circuited. For example, a unit blowing across a hallway will not be as effective as one blowing along the length of a hallway.
Where do I place the outside unit?
The copper used in the connecting pipes and wiring is very expensive and so the shortest distance is the cheapest, but might not be aesthetically pleasing. Discuss with your installer the best place and the cheapest places, and then decide. It is best to avoid positioning of the outdoor unit adjacent to your, or your neighbours bedroom.gs.
How long does it take to install?
A Fujitsu Accredited Installer will usually take around 5 to 6 hours to install a straight forward (back-to-back) system. More complex installations including multi-systems and ducted systems can take longer.
