The Effect Of Heat Pumps On Indoor Air Quality

Charlie Clark • June 9, 2024

Heat pumps are an extremely popular heating and cooling solution for many households and businesses. Heat pumps are well-known for their ability to maintain comfortable temperatures throughout the year, however, their impact on indoor air quality is often overlooked. Throughout this blog post, we will explain the effect air source heat pumps have on indoor air quality, followed by some advice on how to maintain a healthy indoor environment.

How Do Heat Pumps Work?

Air source heat pumps work by transferring air from outside to heat or cool your home. They utilise a compressor, an evaporator coil, and refrigerant to transport heat from one location to another. Heat pumps gather heat from the air inside your home and release it outdoors when it's in cooling mode. In heating mode, they absorb heat from the outside air and transfer it inside.

Do Heat Pumps Improve Indoor Air Quality?

Heat pumps utilise clean energy and do not use fossil fuels, this leads to a reduction in indoor air pollution and carbon emissions. They provide constant air circulation, eliminating stagnant air and maintaining steady indoor temperatures. Most heat pump units possess air filters that are able to catch dust, allergies, and other pollutants, improving air quality even further.

Potential Changes To Indoor Air Quality

Failing to properly install or maintain your heat pump could potentially lead to poor air quality. If your air filters are clogged and have not been replaced in a while, this will cause a reduction in air filtration efficiency. Inadequate ventilation within a home that utilises a heat pump can lead to stale indoor air and elevated levels of contaminants.

Tips To Maintain Healthy Indoor Air Quality

- Keep your system's air filters clean and replace them on a regular basis to continue efficient filtration. 

- Schedule
annual maintenance with a trained HVAC experts in order to check for issues with your system and ensure it operates efficiently.

- Consider using a
dehumidifier alongside the heat pump to maintain proper humidity levels and prevent the development of mould. 

- To
reduce indoor pollution levels, open windows or operate exhaust fans on frequently.

- Add an air
purifier or UV air sanitizer to your home to help eliminate particles from the air.

- Ensure you are utilising
natural cleaning products and avoid smoking indoors to decrease indoor air pollution.

- Consider welcoming some
plants to your indoor space to bring oxygen and clean the air, such as a spider plant or peace lilies.

Heat pumps are an energy-efficient and sustainable heating and cooling solution that is able to improve the air quality inside your home. Understanding how heat pumps work, the benefits they offer, and the potential issues they can cause allows homeowners to take proactive measures to maintain a healthy indoor environment. Follow these maintenance tips and extra measures to ensure that your heat pump contributes to better indoor air quality and a more comfortable living environment for you and your family.

The first compelling reason air-source heat pumps are becoming the standard in modern homes is their remarkable efficiency. Unlike traditional heating systems that generate heat by burning fuel, heat pumps transfer existing heat from outside air into your home. This fundamental difference means they can produce up to three times more heat energy than they consume in electrical energy. For homeowners, this translates to substantial savings on heating bills while maintaining consistent comfort throughout their living spaces.

Careful planning is the first step in building an energy-efficient home. Think about how the entire house can function as a system when integrating an air source heat pump into your design. Start with adequate insulation; well-insulated foundations, attics, and walls reduce heat gain in the summer and loss in the winter. This enables your heat pump to run as efficiently as possible, consuming less energy to keep temperatures acceptable. By lowering heat transfer, high-quality windows with double or triple glazing go well with your heat pump system. Larger windows should be placed on south-facing walls to absorb winter solar heat, and summer sun should be blocked with the proper shade.

Household carbon emissions are greatly increased by traditional heating systems. Electric resistance heaters and gas boilers are energy-intensive devices that frequently directly or indirectly use fossil fuels. You can retain maximum comfort and drastically lessen the environmental impact of your house by making the switch to an air-source heat pump.
