Key considerations include the size of the area you wish to heat or cool, if you want to heat or cool just one room or your entire home, the local climate, the number of windows in the area, insulation in the walls and possible location options. For an electric heating and cooling solution, we recommend that you have an Accredited Heat Pump professional do a full assessment of your home and your comfort requirements to ensure you get the correct heat pump and sizing for your geographical location and unique requirements. For more information, take a look at our ‘How to Choose the Right Heating & Cooling Solution for your Unique Space’ blog article here: rinnai.co.nz/blog/home-heating/choosing-the-right-heating-and-cooling-solution-for-your-unique-space
Every home is as individual as its owner in its requirements and choosing the wrong size Heat Pump for the room you are wanting to heat can leave you cold and cost you more in power consumption. Correctly determining the size of equipment for your space is critical and directly relates to how much energy or heat the unit can produce. An undersized unit will be ineffective in bringing a room to the desired temperature, while an oversized unit will turn off and on frequently, causing wear and tear. Aspects to be considered include – the size of the room you wish to heat; how many doors and windows it has and how they are situated; is the room insulated - to name a few. Because of the technical nature of correct sizing, the key to selecting the right size Heat Pump for your home is an assessment and discussion of your needs with an accredited Heat Pump professional.
Typically, Heat Pumps are sized and installed to heat a single room or area. To heat your whole home, you may need several Heat Pumps, or a Ducted Heating & Cooling System. For more on Ducted Heat Pump Systems take a look at our 'What is a Ducted Heat Pump System' blog article here: rinnai.co.nz/blog/home-heating/what-is-a-ducted-heat-pump-system
Factors such as the energy efficiency of your particular unit, whether it is sized correctly for the area, your individual energy company rates and how effectively you use the unit will all be a consideration here. EECA (The Energy Efficiency & Conservation Authority) has identified Heat Pumps as one of the most energy efficient forms of heating around. Heat Pumps do not create heat, they simply move available heat from one place to another. The little energy that is needed is predominantly used to run the compressor. A Heat Pump typically uses 1kW to create 4kW of heat. The result is around 4 times less energy needed to that of traditional electric heaters, saving you money by reducing your power bill. Running your heat pump is roughly one quarter the cost of traditional electric heating and are one of the most cost-effective ways of keeping your home warm and dry.
Heat Pump servicing is often overlooked as an integral part of maintaining the longevity and efficiency of the unit. It is recommended that you have your Heat Pump professionally serviced every 12 months, ideally before the start of winter, to ensure your unit is working optimally. Whilst DIY home maintenance will help keep your unit working effectively and efficiently, it does not replace the need to have your system professionally serviced by an accredited Heat Pump Air Conditioning technician. A professional service will ensure your system will operate smoothly and efficiently delivering comfort to your home environment whilst extending the life of your investment. As a guideline, your Heat Pump should be serviced annually.
Experienced and qualified installers usually take somewhere around 3-4 hours for a straightforward back-to-back (where the indoor unit and outdoor unit are positioned directly opposite each other on the interior and exterior of a wall) Heat Pump installation. More complex Heat Pump installations will take a bit longer. Ducted systems can take between one to two days depending on the amount of spaces to be ducted. Installing a Heat Pump is a complex process requiring qualified trade professionals so must ALWAYS be undertaken by a reputable accredited installation company.
Common sense tells us that no heating appliance should be used 24 hours a day. Using your heat pump correctly is using it as required. If you are not home during the day, there is no need to run your heat pump during the day, adding to your power bills unnecessarily. If your home has good insulation, a couple of hours in the morning and a few hours in the evening should suffice.
We would advise running your Heat Pump somewhere between 18 and 22 degrees on heating in Winter. If you want to keep it on all night you can drop the temperature back to around 18 degrees – or use the ‘Sleep Function’ (Q Series feature) to take of it for you. During the summer, you can run your Heat Pump on cooling at around 18 or 19 degrees and if you wanted to run it all night you could increase the temp by a degree or two.
When the temperature drops, Heat Pumps perform a defrost cycle to remove ice build-up on the outdoor heat exchanger. Ice build-up occurs during the heat process as the outdoor unit takes the moisture and heat from the air. The defrost cycle is a necessary part of the Heat Pump’s operation, as the airflow can be restricted if the heat exchanger is covered in ice, which will subsequently affect its efficiency. Ice also acts as a thermal insulation barrier on the heat exchanger preventing heat absorption. By defrosting the heat exchanger the unit’s efficiency increases. In defrost mode the Heat Pump will stop heating for short periods of time and it’s important not to turn your system off when it’s going through this cycle.
The average warranty period for a new Heat Pump in New Zealand is five years but Rinnai offer a 6 year warranty when the Heat Pump is installed by a Rinnai Accredited Installer (5 years for non-accredited installers).
Try changing the batteries in the remote again, as even in a new pack there may be faulty batteries. Your remote control will need the batteries changed periodically, when the screen becomes faint or when it becomes less responsive. When you do this, the heat pump will revert to its factory settings and will need to be readjusted. You can avoid this by changing one battery at a time.
