Are MVHR Systems Worth It

Yes, MVHR systems are definitely worth it.

That being said, the decision to install an MVHR system is a significant one, sometimes involving a substantial upfront cost. However, the long-term benefits in terms of improved indoor air quality, energy efficiency, and comfort can make it a worthwhile investment for many homeowners.

Key benefits of MVHR systems:

• Improved indoor air quality: By constantly circulating fresh air and removing stale air, MVHR systems help to reduce allergens, pollutants, and moisture, creating a healthier living environment.
• Energy efficiency: Through heat recovery, MVHR systems can significantly reduce heating costs by reusing heat from extracted air to warm incoming fresh air.
• Reduced condensation and mould: By removing moisture-laden air, MVHR systems help to prevent condensation and mould growth, common problems in many homes.
• Consistent temperature: By distributing warm air from the heat exchanger, MVHR systems can help to maintain a more even temperature throughout your home.

Factors to consider:

• Upfront cost: MVHR systems can be expensive to install, including the cost of the unit, ductwork, and professional installation.
• Running costs: While MVHR systems are generally energy-efficient, there will be ongoing costs associated with electricity consumption for the fans. However, this is offset by the proposed savings you can make from not needing to use your heating as much, due to the MVHR system.
• Home suitability: The effectiveness of an MVHR system can vary depending on the size, layout, and insulation of your home.
• Maintenance: Regular maintenance is essential to ensure optimal performance and longevity of the system.

To determine if an MVHR system is worth the investment for you, consider the following:

• Your home’s condition: If you experience issues with dampness, mould, or poor indoor air quality, an MVHR system can be a valuable solution.
• Your energy bills: If you’re looking to reduce your heating costs, an MVHR system can help to achieve this.
• Your long-term plans: If you plan to live in your home for many years, the long-term benefits of an MVHR system may outweigh the initial investment.
• Government incentives: Check if there are any government grants or incentives available to help offset the cost of installation.

Ultimately, the decision to install an MVHR system is a personal one. While it’s a significant investment, the potential benefits in terms of health, comfort, and energy savings can make it a worthwhile choice for many homeowners.

Is there an alternative to MVHR?

In terms of mechanisms, there are little to no alternatives that provide the same level of help that https://www.i-sells.co.uk/product-category/ventilation-heat-recovery/ can. However, there are non-mechanical options that could help ventilation issues in your home.

If you’re losing too much heat, you should…

• Check whether you need to replace your insulation.
• Invest in double or triple glazing windows.
• Ensure your front and back door has no drafts passing through them.
• Check the walls of your home for any large cracks or drafts.

If your home is too humid, you should…

• Consider employing a basic ventilation routine daily.
• Open windows when cooking/showering
• Keep fluffy items out of rooms such as bathrooms or kitchens, as moisture can catch onto these surfaces.
• Use your central heating at specific times, such as when you wake up, when you arrive home from work, and before you go to bed.

What are the downsides to MVHR?

There are practically no downsides to having a MVHR unit. Its function and effects do not leave any room for any negative consequences. Depending on the MVHR type you purchase (single or multi-room), you may require additional space in the home. Whether this be for additional venting or to house a multi-room unit. This can be an issue if you live in a small dwelling.

Some would argue that the unit does not heat up the room it is in enough. However, the unit is not designed to be a heating unit. It is primarily for ventilation, its function via the heat exchanger is so no additional heat is lost, rather than being used as a heating unit.

The only time you would have an issue with MVHR in terms of functionality is if it is not installed correctly, and has not been properly commissioned. You can easily avoid this by using recognised professionals in the installation and setting of your MVHR unit.

Can MVHR help with allergies?

Yes, MVHR systems can significantly benefit people with allergies.

By continuously circulating fresh, filtered air, MVHR units help to reduce the levels of allergens like pollen, dust mites, and pet dander indoors. This is achieved through a combination of factors:

• Filtration: MVHR systems use filters to capture airborne particles, including allergens. Regular filter replacement is essential for optimal performance.
• Dilution: By constantly introducing fresh air, MVHR units dilute the concentration of allergens in indoor air.
• Reduced humidity: MVHR systems help to control humidity levels, which can reduce the growth of mould and dust mites, common allergens.

It’s important to note that while MVHR systems can greatly improve indoor air quality, they might not completely eliminate allergens. For those with severe allergies, additional measures such as air purifiers with HEPA filters might be necessary.
