As the name suggests, a ventilation system is designed to ventilate – introduce fresh air into an area. When the introduced air is colder than inside they can use electric heaters to boost the temperature. The heating efficiency is therefore the same as an ordinary electric heater. Spend a $1 and get $1 worth of heat. Heat pumps transfer heat, not air, from outside into the home. They do not need a heating element.. A heat pump will return more than $3 worth of heat for every $1 you spend with a properly sized and installed heat pump. They also reverse to cool your home in summer. Fujitsu Ducted and Cassette heat pump systems are able to have connections providing fresh air ventilation.

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 to the new “dew point” 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 the area warm.

Yes, in summer they will utilize the cool air to act as a dehumidifier. They will not “de-condensate” in heating mode (in winter). In winter they will keep your room (house) above the dew point, which will inhibit condensation.

A single outlet heat pump like a Hiwall or Console type is very unlikely to heat your whole house. Heat pumps are likely powerful, efficient fan heaters. A typical heat pump provides the same amount of heat as having three fan heaters lined up together, but only costs about 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. But typically, heat pumps are sized and installed to heat a single room or open area. To heat your whole house, you will probably need several heat pumps, or a multi head heat pump system or a ducted system.

Until recently, the bigger heat pumps could only work with a three phase power which is not available in most homes. Now, Fujitsu have single-phase Inverter technology for our heat pumps, which has allowed bigger capacity units to be capable of heating very large areas.”What size heat pump will I need for my home?”Modern inverter heat pumps have a greater capacity for variations in the temperature. That is because they can increase or decrease their output. But there is obviously a limit. It takes almost twice as much energy to heat a house from 2 degrees to 20 degrees as from 7 degrees to 20 degrees. So if you want to make sure you are going to get heating in all situations the heat pump needs to be sized correctly.Size Matters – this statement is on all our product brochures. There are many methods used to size and select a heat pump, the results can be widely different causing unnecessary confusion. Fujitsu have decided to help fix this and release a software program that will produce an accurate and easy to read report allowing you to see exactly how your heat pump has been sized. Just ask for EzeCalc report and get an accurate sized heat pump for your home.

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 it is important that your installer has selected a correctly sized unit for your home. You can get an accurate size for your ventilation system with EzeCalc.What is the “star rated” figure?Inverter heat pumps have a range of outputs depending upon the load put on them. The ’star rated’ figure is the point at which the unit is running at its most efficient self. That is the running speed you want to have in your home for best efficiency. The efficiency of the system decreases when there are sudden temperature differences in the environment of your home i.e. when very cold air enters your room from the outside or when you first turn it on heat the room.

No, most modern heat pumps are very quiet. The source of noise in a typical heat pump is the air passing over the grill, as it is blows through the unit. This sound is usually only marginally higher than ambient room noise. Fujitsu technology also developed a “quiet mode” on many models, which means that once the room has reached it’s desired temperature, the sound is usually less than the sound of a soft whisper. We measure sound levels of all our heat pumps (in decibels) and they are clearly set out in the specs page on our brochures.

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. This could require cleaning twice per year. In addition the outside unit should be kept clear from any greenery and the coil should be cleared of any blockage. Further instructions relating to these requirements are in your user manual. A wise alternative is to arrange your installer to schedule an annual clean and maintenance check on the unit.

Yes. The indoor unit on cooling will dehumidify and the resultant water needs to be led away. That is why they are typically mounted on an outside wall. If not, a condensate pump can be used to lift the water to the ceiling to be drained out. But sometimes condensate pumps can be heard when they operate. The outdoor unit when on heating will also produce water. The amount of water produced is similar to a dehumidifier in use.

The units require connecting piping to be added plus professional wiring during installation. When installing a unit, the pipes need to be connected, and the wires have to be professionally installed. There is a national shortage of skilled installers. Correct installation requires specialist tools with a combined worth of more than $5,000. Fujitsu accredited installers are reliable and have professional workmanship. They are not our employers or agents of ASAP AIR but we have the confidence that they have the tools and professionalism to follow installation guidelines.

Heat pump technology is so advanced these days, that choosing the best type to suit your needs can be confusing. So, to help simplify your decision, here’s a checklist:

How many rooms do you want heated? You can buy a single heat pump to heat a single area or room, a “multi-system” to heat 2, 3 or 4 areas, or a fully ducted system if you wish to heat your whole home.
Split Systems – All modern heat pumps are split systems. That means they have an outdoor unit which contains the compressor, and an indoor unit which contains the fan that circulates the warm air (or cooled air in the summer) in your home. These units are designed to be discreet both in appearance and operation.Next, choose the indoor type and model that suits you best.

Today’s heat pumps are unobtrusive in size and style, with low noise levels. There are various types. Some can be recessed into walls, Hiwalls are mounted on walls close to the ceiling, floor consoles look like traditional heaters, and some can be recessed into walls. Cassettes and Ducted split systems can be hidden in the ceiling.

Outdoor units vary in size, but most are about the size of a large suitcase. The outdoor unit is located in a position that is unobtrusive, and where it is easiest to run pipe work between the indoor and outdoor units. Your accredited Installer will suggest the best location for your system.

EECA has recommended heat pumps for heating because they use significantly less energy than any other type of heating systems. Because they use significantly less energy to heat your home than any other type of heating. This reduces both pollution and the release of green house gases. Check the model you are buying for it’s Energy Star rating.

A heat pump (also known as a reverse cycle air conditioner) is a very clever device that extracts heat energy from one volume of air and transfers it to another. So one body of air gets warmer, while the other gets cooler.

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.

This depends on the amount of heating required. Heat pumps transfer heat from outside air and in this way produce three to four times more heat. Its efficiency is 300% to 400%. This means for every 5kW of heating you pay for around 1.5kW of electric energy. Heat pump heating is roughly one quarter the cost of electric heating and about one third the cost of gas heating.
