Our Frequently Asked Questions


Heat pumps do not generate heat but extract it from one body of air and transfer it to another. They use the same principle as your fridge, compressing gas and then allowing it to expand, extracting heat as it does so.

Even if the air outside is freezing, heat pumps can extract heat energy and transfer it inside to keep you warm. In summer the system works in reverse, extracting heat from indoors and transferring it outside leaving you comfortable and cool.

Heat pumps offer many benefits over other forms of heating. Firstly they are much cheaper to run giving up to 4 times more heat than you pay for, they can be used all year round for cooling, air filtering and dehumidification. They are safe and easy to use.

Heat pumps produce low density heat which is safe for children and the elderly, unlike fires or electric heaters. They are unmatched for convenience and ease of use (Remote Controlled). They don’t pollute our atmosphere as with products for combustion and they use ozone friendly refrigerants.

Every home is as individual as its owner. The key to selecting the right heat pump for your home is accurate assessment of the heat that will need to be transferred into your home in winter for heating, and out of your home in summer for cooling.

The amount of heating needed will depend on the potential for heat loss through walls, windows and roofs. To minimise this loss, good insulation is recommended. By insulating first, the size of heat pump selected will be generally smaller and therefore cheaper to run.

The aspect of the home is also an important factor as north facing rooms are generally warmer and require less heating.

Lots of old ideas about how heat pumps work. Technology is so much more advanced these days. The heat pump constantly measures your environment inside and out to give you the best outcome by varying it’s compressor speed to suit the environment and maintain the set temp.

At Napier Heat Pumps. Our advice is to run the heat pumps when you are home.
Running constantly lessons the life span of the heat pump. Heat pumps should last about 25000 hrs or approx. 15 years.

Using a timer to switch on before getting up in the morning and switching off before leaving for work will help save power and run time.

There is a sweet spot for both heat and cool 18-21 degrees in heating. This helps reduce damp and mould in the home closing unused rooms and curtains will help reduce power consumption.

In cooling, set 23-26 degrees also shutting off unused rooms and closing curtains. This will help reduce the heat load in summer.

In winter, set to heat once set temp is reached. The heat pump will slow down and idle along or stop.

Set your louvre to point on the floor ½ way into your room and the fan on auto this will heat the cold on the floor first and it will rise to the ceiling. The heat pump will suck it up and send it to the ground again.

In summer set to cooling. Point the louve up in the air and auto fan. This will give you nice even cooling as cold air drops.

Set the fan on Auto mode. This will quickly heat/cool the room and will then slow down and maintain the required temperature which will be energy efficient. Auto mode for heating and cooling uses more power as it constantly switches between both modes to maintain the set temp and the heat pump is constantly running using more power.

At Napier Heat Pumps we recommend having your heat pump serviced before winter as this will be when you use it the most.

Cleaning the filters, disinfect the coil, flushing out the drain tray and cleaning off mould from the interior fan area.

Flushing out the outdoor coil and cleaning the paint work helps maintain the outdoor unit in the harsh Hawkes Bay environment.

Service at least once a year but if you use it a lot in cooling you may want to get it done before summer as well. This will increase the lifespan of your heat pump.

  • Single-split system (one indoor unit and one outdoor unit) suitable for an individual room
  • Multi-split system (multiple indoor units connected to one outdoor unit) suitable for multiple room situations.
  • Ducted systems. One outdoor unit connected to one or more concealed indoor units with the heat distributed via ducting tubes to individual rooms. Suitable for whole house solutions.

Yes. Heat pumps are extremely reliable. They use the same process as a home fridge or freezer and have the same level of dependability and life expectancy. The top brands come with 5 Year manufacturer’s warranty or more.

All Heat Pumps that are sold in New Zealand are required to have a star rating and must meet a Minimum Energy Performance Standard (MEPS).

The MEPS (Minimum Energy Performance Standard) for New Zealand is a COP (Coefficient of Performance) (Heating) and EER (Energy Efficiency Rating) (Cooling) of 2.3. All appliances that reach this level are awarded 2 stars. For every .3 increase in either the COP or EER the appliance receives another star.

All Heat Pumps have two star ratings, one for heating and one for cooling. The more stars the more energy efficient.

No. Unlike fires and glowing electrical elements, heat pumps don’t burn oxygen.

Yes, they are, but it is still very important we visit your property to ensure complete compliance.

There are multiple benefits to ducted air conditioners and ducted heat pump systems.

A ducted system is a great way to cut costs on your electricity bills because you get to control the rooms you heat or cool in your home. Another bonus is you won’t have to worry about bulky heat pump units within your home since each unit is installed within the roof or underfloor cavity. There’s no need to worry about any noises – a ducted system is exceptionally quiet.

Yes, heat pumps are generally considered energy-efficient heating and cooling systems. Heat pumps transfer heat from one place to another rather than generating heat directly. In heating mode, they extract heat from the outside air and transfer it into the indoor space. In cooling mode, the process is reversed, and they extract heat from the indoor space and release it outside.

The lifespan of an air conditioner depends on many factors, such as the quality of the unit, usage, maintenance and environmental conditions. However, a well-maintained air conditioner can last up to 10 to 15 years or even longer with proper care.

Regular maintenance is recommended to prolong your air conditioner’s life. This includes cleaning the coils and replacing the air filters.

They don’t need to be changed at all! However, you should check and clean the filters regularly. Check your user manual or seek guidance from professional technicians like our team at Napier Heat Pumps for recommendations

Yes, in cooling mode – the coils of the indoor unit of the air conditioner work as an evaporator and drain out the water from the hose attached to it which leads to sweating.

Yes, generally heat pump/aircon aids people in such conditions with its technologies that eliminate allergens and pollutants.
