Can Flex Duct Be Used for Heating?

Yes, you can use flexible ducting for heating, whether this be in ventilation systems that distribute heat, or in systems that extract heat.

However, the effectiveness is subject to the type of ducting you choose. Plastic ducting will not be suitable in some high-heat environments, however, metal ducting presents the perfect solution.

Depending on the flexible metal ducting you choose, they can withstand temperatures of -30C all the way to 150C. We must clarify that this will vary depending on the ducting you choose, make sure to read the product specifications before committing to buying ducting from our range.

We understand that you have specific needs and therefore have more questions, get in contact with us directly if there are questions before making a purchase.

What happens if my ducting overheats?

If your metal ducting exceeds its temperature limits, it may become a fire hazard, along with this, you may find the effectiveness of the ducting reduced. Additionally, it may become misshaped, as heat makes metal expand.

Plastic ducting, if overheated will likely melt, plastic ducting isn’t generally placed in environments where this is a possibility so the likelihood of plastic ducting melting would be in the case of a mishap such as a fire.

Does heat affect metal ducting?

Yes, heat can affect metal ducting, specifically round ducting. This is due to metal expanding when it is under heat, though it is more of a concern for industrial environments than home use. Regardless, if you plan on having ducting in areas with high heat and would like some guidance, we are always here to help.
