How a Dehumidification Heat Pump Can Help You and Your Family

During the summer on the North Shore MA and Seacoast NH areas, humidity is a problem for many homes. High moisture levels in air cause discomfort for those inside and can lead to damage to the home and even mold growth.

Unlike traditional furnace-based HVAC systems, heat pumps dehumidify during the cooling season. This is thanks to their ability to pull moisture out of the air during the cooling process.

Energy Efficiency

Many heat pumps come with a dehumidification mode that works even when the unit is not in heating mode. This is because of how heat pumps work: by circulating air through the refrigerant, they also pull in moisture from the outside air, and the moist air will cool down as it passes through the condensation coil. The condensate will then give up its heat to the air (which is cooled by the indoor fan) and the condensation cycle will continue until the humidity is low enough for your comfort.

This means that your heat pump will be able to dehumidify your home without impacting your heating efficiency. This can have energy savings implications, especially during the summer. Having lower humidity levels allows you to set your thermostat at a higher temperature, meaning your heat pump will be running less. This can reduce your energy usage and bills.

Of the four systems studied, system 3 is the best. This system uses a membrane-based total heat recovery for the incoming ventilation air. This system recycles the enthalpy of the exhaust air by cooling and drying it with a membrane. This system saves primary energy by 29-42% compared to a dehumidification system without any energy recovery measures. Hour-by-hour energy consumption of the systems was measured to compare their performance. The results show that the system of independent air dehumidification using a membrane-based total heat recovery saves the most energy.

Health

High humidity levels encourage mould, mildew and other microbial growth, which can cause respiratory illnesses. A dehumidification heat pump extracts moisture from the air and keeps it at healthy levels, which helps you feel better and avoid illness.

While all heat pumps control humidity as a natural byproduct of heating and cooling, newer models have an added benefit of a dry mode that actively removes moisture from the air, even when it’s cool. It does so by alternating constantly between cooling and heating modes, drawing moisture dehumidification heat pump out of the air without sacrificing temperature control. This means your home will feel cooler at a lower temperature, which saves energy while improving comfort.

Humid conditions also increase the likelihood of developing mould on clothing, furniture, bed linens, towels and curtains. This can create odours that make a home smell musty and unpleasant, but dehumidification reduces the risk of such problems.

Ductless mini-split heat pumps, such as the Mitsubishi Electric ductless mini-splits installed by our experts, are an effective solution for tackling both summer humidity and winter heating in North Shore MA and Seacoast NH homes. They’re highly efficient and offer superior dehumidification capabilities, including in heating mode. They’re also powered by clean electricity, which further amplifies their environmental benefits. This means you’ll cut your carbon emissions considerably compared to the typical gas furnace used in the area.

Safety

Humid air can make your home feel warmer, which makes your air conditioner work harder to cool the space. By eliminating excess moisture with a dehumidification mode, your system can keep up with the temperature without overworking its compressor and using more energy. That’s good news for your electric bill and a healthier home environment.

Dehumidification also makes your heating and cooling system more efficient. The air is less humid, so you can set the thermostat a little higher and still enjoy comfort. That’s better for the HVAC system and your energy bills and can help you reduce wear and tear on equipment and the costs of repairing or replacing it.

Your basement may be prone to condensation, but a dehumidification heat pump can remove that from the air before it enters your ductwork. This can help protect your flooring, walls and furniture from mold, mildew and rot. It can also reduce the odors that are associated with these conditions and keep your family comfortable.

Your ductless heat pump is designed to dehumidify in both heating and cooling modes. This is because, like traditional central air conditioning systems, it operates using a closed loop design that pulls in cooler outside air, heats it, then sends it back into the house. As the refrigerant in this process goes through a cycle of compression and expansion, it condenses water vapor into the surrounding air.

Comfort

Excess moisture in the air promotes dust mite and mildew growth and contributes to allergies and asthma. Keeping your home’s indoor humidity at the optimum level with a dehumidification heat pump prevents these triggers from affecting your family.

Dehumidification also makes your heat pump more efficient. High humidity can cause your home to feel warmer than it really is, leading you to set your thermostat at a higher temperature in order to maintain comfort. dehumidification heat pump The dehumidification mode causes your heat pump to alternate between heating and cooling modes, allowing it to continually draw moisture out of the air without sacrificing temperature control. This has the knock-on effect of lowering energy costs and reducing your carbon footprint.

If you have a ducted or split system heat pump it’s worth checking whether it has the option to dehumidify. Many modern ducted and split system heat pumps come with smart features which can heat, cool, dehumidify, ventilate and purify your air at the touch of a button on a user-friendly remote. This is especially useful in homes where a stale musty smell is lingering.

In summary, a dehumidification heat pump is an excellent investment for any home. Not only do they help to maintain an optimum temperature and reduce energy consumption, but they can also protect your health, save you money and give you a fresher more pleasant smelling home.
