Heat Pumps do not work like ventilation systems. Ventilation systems introduce fresh air into the area and they may also heat the air on the way. When it warms the air it can only supply one dollar's worth of heat for every one dollar spent on power. On the other hand heat pumps only transfer heat and there is no need for a heating unit. In fact for every dollar you pay to run your heat pump you will bring more than three dollar's heating into the room. In summer heat pumps can be reversed to pump the warmth out and act as Agent Compressor Condensing Units air conditioners. If you do require ventilation some Fujitsu Heat Pumps can be supplied with ventilation capabilities. Cassette and ducted varieties are the ones to choose for this. https://www.bfcold.com/product/heat-pump-unit/ Humidity is normally a problem in the warmer months and that is when heat pumps are able to dehumidify. In winter they do not actively dehumidify but keep the room temperature above the level at which condensation occurs. Condensation occurs when warm moist air cools and can be prevented by either removing the moist air or keeping the area warm. It is expensive to heat the cold winter air and although it would be ideal to both heat and ventilate it is most cost effective to heat only.

Most homes will need more than one heat pump to heat the entire house. Heat pumps offer three times the heat of a comparable fan heater. Most heat pumps can heat a single room or a large 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. However, Fujitsu Heat Pumps now have a range of larger capacity units with single phase inverter technology Frequency Condensing unit which are able to heat much bigger areas.

Most heat pumps today operate with little noise. Some Fujitsu Heat Pumps come with a quiet mode and when the desired temperature is reached they will be almost inaudible. 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. Inverter models are able to accommodate a greater range of temperatures but it is not unlimited. 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.
