A heat pump is not a ventilation system. Ventilation systems introduce fresh air into the area and they may also heat the air on the way. The heating part is like any other electrical heater and for every dollar spent on heating you will get a dollar of heat in your room. On the other hand heat pumps only transfer heat and there is no need for a heating unit. For every dollar spent in heating you will actually introduce at least three dollars worth of heat into the area. In summer heat pumps can be reversed to pump the warmth out and act as air conditioners. However, some models of Fujitsu Heat Pumps can also be fitted with ventilation connections. These are the ducted and cassette models.
Humidity is normally a problem in the warmer months and that is when heat pumps are able to dehumidify. In winter they counteract condensation by heating to above the temperature that it occurs. To prevent condensation you need to either remove the moist air or heat the room enough. Of course, it is ideal to do both but it can be very costly to heat the fresh and cold air in winter so the most effective option is to just heat.
To heat the whole home generally requires two or more heat pumps. You can think of heat pumps as having the three fold ability to heat as a fan heater would. Generally you can expect a heat pump to heat a single area. Heating the entire home would require several heat pumps, a multi head system or ducting.
Not that long ago you would have required three phase power for the larger heat pumps. Fujitsu Heat Pumps are now available in a selection of single phase inverter units with increased capacity and are capable of heating much larger areas.
Modern heat pumps are generally very quiet. Those Fujitsu Heat Pumps which have a quiet mode are practically inaudible once they have reached the target temperature. The sound level of heat pumps is normally specified in decibels in the brochures so that you can compare different models and choose one that operates at an acceptable level to you.
The heat pump you choose will need to be the correct size for the area you wish to heat and the range of temperatures that you will experience. If it is not the right size it will not work as efficiently as it should and will end up costing a lot more to run. If your power bills are higher than they should be you will either need to increase your insulation or the size of your heat pump. The inverter heat pumps are designed to operate in a larger range of temperatures but there is a limit. Suppliers of Fujitsu Heat Pumps are able to visit your home to do a measure and can advise which heat pump or heat pump system will be best for you. They are able to use EzeCalc software to generate a report ensuring that you choose the most suitable heat pump system for your house.
