As the winter season approaches, many of us may wonder how to block heater vents to save on heating costs or redirect heat to other areas of the house.
However, it’s crucial to prioritize safety when it comes to blocking heater vents. In this blog post, we will discuss the importance of safely blocking heater vents and provide step-by-step instructions on how to do so.
So, whether you’re looking to block heater vents entirely or partially, this blog post will provide you with the necessary information to do so safely. Let’s get started!
Can You Block a Heater Vent?
So, you’re probably wondering if it’s safe to block a heater vent.
The short answer is, it depends!
Blocking heater vents can have benefits, such as reducing heating costs and redirecting heat to other areas of the house.
However, there are also risks and safety concerns that you need to be aware of before blocking your heater vents.
Risks and safety concerns in blocking heater vents
One of the main risks of blocking heater vents is overheating.
When heater vents are blocked, the air cannot circulate properly, which can cause the furnace or heating system to work harder than it should. This can lead to the system overheating and potentially causing a fire.
Another risk is that blocked heater vents can cause uneven heating throughout your home, which can lead to discomfort and wasted energy.
Difference between partial and complete blockage of heater vents
It’s important to understand the difference between partial and complete blockage of heater vents.
Partial blockage means partially covering the vent with a material that allows some airflow, such as using a vent deflector.
Complete blockage means completely covering the vent with a material that doesn’t allow any airflow, such as wood or cardboard. Partial blockage may be safer than a complete blockage, as it allows some airflow and prevents overheating.
However, both methods have potential risks and safety concerns that must be considered.
How to Block Heater Vents?
Materials needed to block a heater vent
- Measuring tape or ruler
- Scissors or cutting tool
- Blocking material (such as magnetic sheets, foam board, or vent deflectors)
- Tape or adhesive to attach the material to the vent
Step-by-step guide on how to block a heater vent
- Identify the location of the vent: Take note of the location of the heater vent that you want to block. This will help you determine the size of the blocking material needed.
- Choose the appropriate blocking material: Determine the appropriate blocking material to use based on the type of vent and the level of blockage you want to achieve. For partial blockage, you can use a vent deflector that redirects the heat flow. For complete blockage, you can use magnetic sheets, foam boards, or cardboard.
- Cut the material to the correct size: Measure the size of the vent and cut the blocking material to fit it. Make sure to leave a little extra material on the sides to ensure proper coverage.
- Attach the material to the vent: Use tape or adhesive to attach the material to the vent securely. Make sure the blocking material is in place and covers the vent completely.
Before blocking your heater vents, you will need to gather the necessary materials. These materials include:
Alternative Methods To Redirect Heat From Vents
If you don’t want to block your heater vents completely, there are alternative methods to redirect heat from vents.
- One method is to use deflectors, which are placed over the vent and redirect the flow of heat.
- Another method is to rearrange the furniture in the room to improve airflow and heat distribution. These methods can be effective in improving the heating efficiency of your home while still allowing proper airflow.
- Getting a professional onboard: You might want to hire a skilled heating contractor to inspect the heat work and ensure that it’s properly sealed and free of any leakages, cracks, or crevices.
- Your heating system might need some servicing: Have a professional on board to clear the heating system of any potential issues or blockages that might be a source of disruption within your heating system. Get this done annually or at least once in two years. It would also help you identify any potential issues before they become a serious menace.
- If your furnace has run out of warranty and requires frequent servicing and repairing, it’s time to get a new one. A more modern, more efficient model would help you cut down on your bills with its latest features.
- Check out for annual fuel utilization efficiency (AFUE), which should be closer to 95 percent. As compared to the older counterparts, it would help you save up to two-thirds of the energy.
However, it’s the verdict of a specialist that can make a significant difference to how much you should spend on your heating system, how often you should invest in getting it serviced, and what you need to do to ensure its long life.
In certain instances, it is even possible that you can block some of your heat vents to save some energy.
Until or unless there is a massive system failure of the built-in heating system for the heat to get trapped inside it and result in something fatal or dangerous, such as a fire.
However, if your expert or consultant deems it safe to do so, you may go about using the unused heat inside the vents and siphon it off and push it toward an area where you and your family spend most of your time.
So, what do you do? Well, let’s get started with sorting out the vents, as this might be the most straightforward option among the rest.
While all the systems are interconnected with each other viaducts, at least one vent should be connected to each of your rooms.
Now, depending on the size of your room, there is a possibility that there are several vents inside the room as well.
Hence to cut down the wastage in the areas where you spend the least amount of time and redirect it to places where it’s required, it might be a good option to close the vent.
In some cases, it may be a good idea to merely slide a lever on the vent itself, which pushes a set of louvers over the opening.
In some modern heaters, you might even have the option of closing the vents via remote control.
If this isn’t the case, you may finally resort to blocking the vent manually.
If that’s the case, and you don’t have any sliding covers to block the vents, or the machine doesn’t work, there are at least a couple of companies online that sell a simple magnetic vent cover that you can put on whichever vent you intend to cover or close off.
If you find it expensive, or if it’s not feasible for you to get one, you can even choose to build a cover at home on your own with any heat-resistant material.
One of the options could be using a fitted piece of cardboard wrapped in aluminum foil and held in place with small magnets and weights.
Alternatively, you could use plywood, which is relatively cheap and resists heat.
If you intend to be a bit more efficient and afford to get a bit adventurous with your heating system, then you may block your venting system and redirect the heat to the areas which need more warmth and attention.
This is a long-term, yet safer solution as compared to the rest. As long as the heating system is sound, there’s nothing really to worry about
